1. Hudson bay was the growth center for the main ice sheet that covered North America during the last Ice Age.
2. 40%
3. 50%
4. They exist because the very tip of the ice burg had an ice cap that melts from its highest point the dome so it melts the water evenly.

1. Hudson bay played a huge role in the last ice age in that it was the bridge to link Canada to Russia. Also the growing of the main ice sheet that covered north America.
2. 20%
3. 40 to 50%
4. Formation of the Greenland Ice Cap: The ice caps form over mountains and when the weather gets cooler, the water freezes near the mountains until it cant melt any more in the summer forming a land glacier. The land glacier then merges with the glaciers in the coast mountains to make a icecap.

What was Hudson Bay's role in the last ice age?
Hudson Bay was the growth centre for the main ice sheet that covered northern North America during the last Ice Age.

What percent of the bay froze last winter?
85%.

What percent of the bay froze in 1959?
Water temperature peaks at 8°-9°C on the western side of the bay in late summer. It is largely frozen over from mid-December to mid-June when it usually clears from its eastern end westwards and southwards. A steady increase in regional temperatures over the last 100 years has been reflected in a lengthening of the ice-free period which was as short as four months in the late 17th century.

Why do ice caps exist?
Additionally, in geologic time scales, the ice caps may grow or shrink due to climate variation.

If you were me, what is one thing you would be sure to see while you were in Churchill?
Polar bears.

What should I take pictures of?
Ice caps and polar bears.

1. What was Hudson Bay's role in the last ice age?
The Hudson Bay was formed during the last ice age. According to Wikipedia, "Hudson Bay was the growth centre for the main ice sheet that covered northern North America during the last Ice Age" The frozen water served as a bridge for animals to cross.

2. What percent of the bay froze last winter?
The entire bay was frozen over.

3. What percent of the bay froze in 1959?
85% of the Hudson Bay froze in 1959.

4. Why do ice caps exist?
Ice caps may grow or shrink due to certain changes in weather. Ice caps exist because of frozen ice.

1. The Hudson Bay was the growth center for the main ice sheet that covered northern North America in the last ice age.
2. 1/3 of the bay
3. 100%
4. Climatic factors still affect ice caps today and during the current warmer climate today, they can retreat in size at a rate easily measured on a yearly scale.

If I were you I would go ona Bluesky Expedition. It is dog sledding!! Doesn't that sound like fun??? You should take pictures of the beautiful landscapes and frozen waters. It must be a sight to see!

1) During the last ice age, the Hudson Bay acted as the growth center for the North American ice sheet. The ice sheet can act as an area for travel or habitat.

2) 20%

3) 40%

4) The surface receives less solar temperature from the sun than other areas.

1. What was Hudson Bay's role in the last ice age?

it was the main source of ice growth during the last ice age. it was also kind of like a big ice-bridge from Russia to North America.

2. What percent of the bay froze last winter?

62% (?)



3. What percent of the bay froze in 1959?

I have no clue, I couldn't find out anything about that.


4. Why do ice caps exist?

because of the sun's rays being the least powerful at the poles, which creates colder weather, which makes the water freeze on the surface.




I think some pictures of the sunrise/sunset would be pretty gnarly-lookin' :)

Hudson Bay's role in the last ice age was that apparently there are pieces of iron scattered throughout the bay that could've affected the plates movement and magnetic field. The percentage of the bay that froze last year was 25% and the amount in 1959 was 75%
Ice Caps exist to move and divide ice away.

4. Ice caps exist there because of the cold climate, allowing them to exist. The ice age could be responsible for this as well.
5. On the first day I got there, I would photograph a glacier/ice cap. On the day I was about to leave, I would photograph the same glacier/ice cap to see if there is any difference due to Global Warming. The Hudson Bay wetlands are very pretty, so I would get a picture of them too.

The last ice age was actually the reason Hudson Bay exsists here today. The reason it was so important in the last ice age was because it completely froze over which made is easy for animals to cross. Ice caps exsists because of frozen water that turns into ice. Hudson bay froze over completely last year in the winter season

1) Hudson Bay was the growth center for the main ice sheet that covered northern North America during the last Ice Age.

2) I can not find the actual percentage anywehere, but im guessing that the amount of the bay that freezes over each year is decreasing due to global warming.

3) Therefore the percentage of the bay that was frozen over in 1959 would be far greater than the percentage today.

4) I have no idea and i dont know where to find it?

The Hudson Bay was the center of glacial growth, during the last ice age. The Hudson Bay fed the glaciers that were on North America at that time. last winter the bay was 50 % frozen and I could not find any data on what % froze in 1959. Ice caps exist because the cold freezes them that way. The extreme cold allows this to happen. I would like to see some pictures of the northern lights and polar bears if possible.

hudson bay in the last ice age was a glacial called "laurentide". it was 4,000 meters thick and connected to greenland glaciers. the bay was 10% frozen last winter. in 1959 the bay was 100% frozen. ice caps and glacriers are the worlds largest water supply. they are important in the hydrologic cycle and affect the volume, variabiliy and water quality of runnoff in areas where they occur. a picture that would be cool to take is a bright full moon within the northern lights. you could go on a buggy and see much wildlife.

Hudson Bay's role in the last ice age was that the largest ice sheet, Laurentide Ice Sheet, was centered on Hudson Bay. All of the other sheets expanded and grew together and began covering over land. Polar ice caps exist because of high-latitude regions that receive less energy in the form of solar radiation from the sun than equatorial regions, which result in lower surface temperatures. One thing that you will see while you are there is the clear night sky filled with the northern lights. I would take pictures of the beautiful vast tundra.

1.The little ice age was preceded by a slight warming period in which scientists believe the Hudson Bay melted enough to bring enough freshwater into the ocean and disrupt the thermohaline cycle and put the ocean conveyor belt at a stop and stop the flow of warm water around the globe.

2. 100%

3. 100%

4. because when there is a heavy enough snow, the snow becomes so hard packed that it turns into ice and then the area around them never becomes too hot to melt the caps.

The waters of Hudson Bay covered much of this lowland at the end of the last ice age. Known as the Hudson Bay lowlands, this region has a layer of sedimentary rock which rests on top of the ancient rock of the Canadian shield. 45 percent of the bay froze last winter. 69 percent of the bay froze in 1959. Ice caps exist because the ice is still melting. It is predicted that all the ice will melt this summer. If I were you, I would be sure to see polar bears and the northern lights in Churchill.

In the last ice age, Hudson Bay's role was that it was the center of the extreme ice buildup. There is not much information on how much of the bay froze last winter but it seems to be about 60 percent. The whole bay froze in 1959. Ice caps exist because there is an excess of water and it freezes in quantities in various locations. If I were visiting the one thing I would be sure to see would be the fort in Churchill, which is also what you should take pictures of.

2.Sea ice begins to form in late October, and the Bay is usually ice-free in early August.

3. I couldnt fing what happened to the hudson bay in 1959 but i presume that it froze.

4.Polar ice caps form because high-latitude regions receive less energy in the form of solar radiation from the sun than equatorial regions, resulting in lower surface temperatures.

Because of the constant changing in global temperature. They contain 75% of the worlds fresh water, and are helpful in determining weather patterns, since their large shape changes dramatically with temperature (heat; melts them)

1) Hudson Bay was the growth center for the main ice sheet that covered northern North America during the last Ice Age. The whole region has very low year round average temperatures.
2)45% of the bay froze last winter
3)69% of the bay froze in 1959
4)Ice caps exist because of frozen ice breaking off from Glaciers and other various large ice masses.

1.It was where the main ice sheet started for the last Ice Age that covered northern North America.
2.45% of bay froze last winter
3.69%
4.Ice flows away from the high point on an ice sheet.

1. The Hudson Bay was the starting point for where the main ice sheet that covered North America in the last ice age.
2. The majority of the bay is frozen over every winter, in recent years it has stay frozen for a shorter period of time.
3. The hole bay freezes over, but in 1959 it stayed frozen for a longer period of time.
4. Ice caps exists to regulate world wide temperatures and maintain global equilibrium.

Try to see some polar bears and take pictures of them.

The Southern Hudson Bay is located on the ancient rock of the Canadian Shield, and the process of deglaciation at the end of the last Ice Age left hundreds of interconnected lakes and watercourses. The central part of the Southern Hudson ecoregion, particularly the watersheds of the Winisk, Severn, Attawapiskat, and Albany rivers, is dominated by wetlands. Much of the Hudson Bay lowlands was flooded by saltwater following the retreat of the glaciers, and then subsequently drained as the result of isostatic rebound and lower sea levels. This left saltwater pools, which over time, were replaced by rainfall; species that were once trapped in the pools became adapted to freshwater.

2. 45% of the bay was frozen last winter
3. 69% in 1959
4. The climate, on a global scale, is always changing, although usually not at a rate fast enough for people to notice.So to prevent bad things to happen we have ice caps.

1 The Hudson Bay was the growth center for the main ice sheet that covered Northern North America during the last Ice Age.
2 About 10% of the Hudson Bay was frozen last year. This isnt good because it causes many polar bears to not have homes or food, and pushes them into the tundra.
3 could not find answer...
4 The The ice caps are important because they are contiually affected by global warming. They may shrink or grow depending on the climate variation.
While being in Churchill you should make sure to take pictures of the Northern Lights as well as the Polar Bears. The Northern lights would be an amazing and beautiful experience you just can miss out on while being in Churchill. As well as seeing the Polar Bears, so many are dieing from the global warming and melting of the ice. It would be awesome if you were to see them while they are still there!

-Ice caps are ice that is cooled to temperatures well below freezing point, which reduces their capacity to flow very greatly.

-If I were in Churchill I would want to see and take pictures of the polar bears, beluga whales, and the many wild birds.

What was Hudson Bay's role in the last ice age?
Hudson Bay was the growth centre for the main ice sheet that covered northern North America during the last Ice Age.

What percent of the bay froze last winter?
85%.

What percent of the bay froze in 1959?
Water temperature peaks at 8°-9°C on the western side of the bay in late summer. It is largely frozen over from mid-December to mid-June when it usually clears from its eastern end westwards and southwards. A steady increase in regional temperatures over the last 100 years has been reflected in a lengthening of the ice-free period which was as short as four months in the late 17th century.

Why do ice caps exist?
Additionally, in geologic time scales, the ice caps may grow or shrink due to climate variation.

If you were me, what is one thing you would be sure to see while you were in Churchill?
Polar bears.

What should I take pictures of?
Ice caps and polar bears.

where the main ice sheet generated to cover most of north america. 46% was frozen and in 1959 69% was frozen. ice caps are formed by the freezing of water over mountain areas and are not affected by topographical features

1. "Hudson Bay was the growth center for the main ice sheet that covered northern North America during the last Ice Age." (http://en.citizendium.org/wiki/Hudson_Bay)
2. 45% of the Hudson Bay froze last winter.
3. 69% of the Hudson Bay froze in 1959.
4. Ice caps are not constrained by topographical features. When it gets very cold, ice sheets are formed and then when it melts, ice flows away from the high point, called the dome, and flows towards the ice cap's pereiphery.

In the last Ice Age the bay create an Ice Bridge. It was a main ice sheet in North America.

45% of the Bay froze over last winter.

69% of the Bay was frozen in 1959 showing what great effects global warming has on the world.

Ice caps exist due to low surface temps in areas of the world.

You will see Polar Bears, orcas, norwals, beluga whales, abd you should take pics of them all

2. well over 80% of the bay was frozen in 1959

3. ice caps exist do to slow surface temperatures in cetain areas of the world

4. I would get alot of pictures of the wild life (polar bears), stay safe though

About 50% of the bay froze last winter and about 70% froze in 1959 and finally We have ice caps due to the tilt of the earth which causes temperatures to stay low.
