Understanding Glacier Formation

What is the First Stage of Glacier Formation?

• The Accumulation of Snowfall

• Glacier Movement

• Compaction

• Ice Formation

What is the process of compaction in glacier formation?

• Compaction is the process of melting ice into water.

• Compaction is the process where accumulated snow is compressed into denser ice due to the weight of overlying layers.

• Compaction occurs when glaciers flow over rocks and erode them.

• Compaction is the evaporation of water from snow, leaving behind ice.

What is firn and how is it formed?

• Firn is a solid rock that forms in mountainous regions.

• Firn is a granular type of snow that forms from the compaction of snow over time.

• Firn is formed from the evaporation of water in glaciers.

• Firn is a type of ice that melts quickly in summer.

How does firn turn into glacial ice?

• Firn turns into glacial ice through compaction and recrystallization under pressure over time.

• Firn turns into ice through freezing rain.

• Firn is transformed by volcanic activity.

• Firn melts into water and evaporates.

What causes glaciers to move downhill?

• The weight of the ice pushing against rocks.

• The wind blowing snow uphill.

• The force of gravity and melting at the base.

• The temperature rising uniformly across the glacier.

What role does gravity play in glacier movement?

• Gravity has no effect on glacier movement.

• Gravity only affects the surface of glaciers.

• Gravity slows down glacier movement.

• Gravity is the primary force driving glacier movement.

How do glaciers shape the landscape?

• Glaciers create landscapes by planting trees and vegetation.

• Glaciers shape the landscape by causing volcanic eruptions.

• Glaciers shape the landscape by eroding rock, transporting sediment, and depositing materials, creating various landforms.

• Glaciers primarily form lakes and rivers without altering the land.

What features can glaciers create as they move?

• Volcanic craters, sinkholes, river deltas, and mesas.

• Valleys, moraines, fjords, and cirques.

• Oceans, lakes and Rivers

• Deserts, plateaus, canyons, and dunes.
