Today, ice covers Earth's North and South poles. These ice caps are called polar glaciers. During an ice age, the polar glaciers grow larger. At the height of an ice age, glaciers may cover as much as a third of the Earth. Canada, the northern United States, northern Europe, and northern Russia all get covered by ice. This ice can be more than a mile (1.6 kilometers) thick.
Much of the world's water gets frozen to make these glaciers. This water comes from the oceans, and sea level drops as a result. Places that had been under water become dry land. Many plants and animals adapt to these changes. Those that do not adapt die out.
During the last ice age, animals with warm shaggy coats flourished. For example, the woolly mammoth, a large elephant-like animal, roamed icy areas of Earth. The mammoths probably used their huge tusks to scrape away the snow in search of plants to eat. Their thick woolly coats protected them from the cold.

What do sea levels do during an ice age?
During an ice age, sea levels typically drop because a significant amount of water becomes locked up in glaciers and ice sheets on land. As the ice sheets expand, they draw water from the oceans, causing sea levels to decrease.
Why were sea levels low during the ice age?
During the ice age, a significant amount of water was locked up in glacial ice, causing sea levels to drop. This resulted in more water being stored on land in the form of ice sheets, which led to lower sea levels globally.
What was the impact of the ice age on the ocean?
The ice age had a significant impact on the oceans by causing sea levels to drop due to water being locked up in glaciers on land. This led to changes in ocean circulation patterns and marine ecosystems. The lower sea levels also connected some landmasses, allowing for the migration of species between continents.
Why are ocean levels lower in the ice age then now?
During the ice age, much of the Earth's water was locked up in large ice sheets, causing sea levels to be lower than they are today. As the ice sheets melted and retracted over time, the water they released flowed into the oceans, gradually raising sea levels to their current levels.
Why do geologists and glaciologists study the Ice Age?
Geologists and glaciologists study the Ice Age to understand past climate patterns, changes in Earth's surface, and the effects of ice sheets on landscapes. This research helps scientists predict future climate changes and understand how glaciers and ice sheets impact global sea levels.

What region of the world was affected by the ice age?
The ice age affected regions all around the world, with significant glaciation occurring in North America, Europe, and Asia. It had a widespread impact on the Earth's climate, sea levels, and ecosystems.

Why was more land exposed during the ice age than it is now?
During the ice age, large amounts of water were locked up in glaciers, causing global sea levels to drop. This resulted in more land being exposed. Today, as the glaciers have melted, sea levels have risen and covered some of the land that was exposed during the ice age.
Is it true that Ocean levels rise during an ice age due to an increase in moisture retention in Earth's global biosphere?
No, ocean levels do not rise during an ice age due to an increase in moisture retention in Earth's global biosphere. During an ice age, water is locked up in ice sheets and glaciers, causing sea levels to drop. The lowered sea levels expose more land, which can lead to an expansion of ice sheets and further cooling.
Did sea levels drop 300 Ft during the last ice age?
According to the most recent research - sea levels were roughly 394 feet lower than they are now during the last ice age. After sea levels rose this caused areas, such as the land bridge between North America and Asia, to completely disappear beneath the ocean.
Why has the ice in antarctica been melting so fast and how is it affecting sea levels?
since your mum lived with the dinosaurs and th ice age
Which of the following statement about the ice age is true?
During the last Ice Age, which ended around 11,700 years ago, much of Earth's surface was covered in ice sheets and glaciers. This period of extensive glaciation had a significant impact on global climate patterns and sea levels.
Why is ice so important to sea levels?
Land ice is very important to sea levels, because when it melts, all the water that was on land moves into the oceans. Sea ice melting will not raise sea levels, because it is already in the water.
