Why are glaciers important?

• They protect certain species

The process by which wind, water, ice, or gravity transports soil and sediment from one location to another.

• erosion
• chemical weathering
• deposition
• physical weathering

A large mass of ice that exists year round and moves over land

• dune
• lake
• river
• glacier

When water in the ground freezes and expands causing a crack in the ground.

• ice wedging
• erosion
• physical weathering
• chemical weathering

The diagrams  shows a natural process that weathers rock.
 Which statement best explains why this process results in weathering?

• frozen water acts as a solute
• water expands when it freezes
• the mass of water increases when it freezes
• frozen water dissolves most types of rock

Which of the following is NOT an agent of erosion?

• Wind
• Water
• Ice Wedging
• Gravity
