Ice shapes the landscape through processes such as glaciation and erosion. Glaciers carve out U-shaped valleys, fjords, and cirques, while the movement of ice can create features like moraines and drumlins. Additionally, when glaciers melt, they can leave behind kettle lakes and outwash plains. Overall, ice significantly influences topography and can create dramatic landforms.

Can a boundary be formed by land or water?
Yes, boundaries can be formed by both land and water. Land boundaries are typically defined by physical features such as mountains, rivers, or roads. Water boundaries can be natural features like rivers or lakes, or man-made features like canals or artificial islands.
What is the difference between a ice sheet and a ice shelf?
An ice sheet is a massive glacier that covers land, while an ice shelf is a floating platform of ice attached to the coast. Ice sheets are formed from accumulated snow over thousands of years, while ice shelves are formed from glaciers flowing off the land.
When did Beringia form a land bridge from Asia to north America?
Beringia formed a land bridge between Asia and North America around 20,000 to 10,000 years ago during the last Ice Age. This land bridge allowed the migration of humans and animals between the two continents.
What land features are formed from a convergent boundary?
Land features formed from a convergent boundary include mountain ranges, volcanic arcs, and deep ocean trenches. These boundaries occur when two tectonic plates collide, leading to crustal uplift and intense geological activity that can create dramatic landscapes.
What land features are formed from ice erosion?
Land features formed from ice erosion include cirques, u-shaped valleys, and fjords. Cirques are bowl-shaped depressions at the head of a glacier, u-shaped valleys are deep valleys with steep sides carved out by glaciers, and fjords are long, narrow inlets with steep cliffs created by glaciers flowing into the sea.
What is land based ice?
Land-based ice is ice that has formed over land. A glacier is an example of land-based ice. Glaciers are common in the northern areas of Canada and the North Pole.
What is formed when a ice cap spreads past the land to cover part of the ocean?

How do melting glaciers shape land?
When the glacier is formed the ice scratches the land. When the glacier recedes the ice will scar the earth. This is called glacial scarring.
Can a boundary be formed by land or water?
Yes, boundaries can be formed by both land and water. Land boundaries are typically defined by physical features such as mountains, rivers, or roads. Water boundaries can be natural features like rivers or lakes, or man-made features like canals or artificial islands.
What plate boundary formed the land features of Mount Saint Helens?
Convergent
What land features are formed by gravity erosion?
Land features formed by gravity erosion include cliffs, rockfalls, landslides, talus slopes, and scree fields. These features are a result of the constant downward pull of gravity causing erosion and movement of rocks and sediment downslope.
What are some features formed by glacial deposition?
Some features formed by glacial deposition include moraines (ridges of till), drumlins (elongated hills), eskers (sinuous ridges of sand and gravel), and kettles (depressions formed by melting ice blocks).
What is the difference between a ice sheet and a ice shelf?
An ice sheet is a massive glacier that covers land, while an ice shelf is a floating platform of ice attached to the coast. Ice sheets are formed from accumulated snow over thousands of years, while ice shelves are formed from glaciers flowing off the land.
What geographic feature was common to all of the ice ages?
Glaciers and ice sheets covering large portions of land were common features during all ice ages.
How is an ice shelf formed?
Over millennia, ice builds up on land, which slopes into open water. Over time, gravity forces the ice to flow downhill into the water. A ice shelf is formed because the water's wave action has not broken off the ice to form icebergs.
