Weathering, Erosion & Deposition

The major agent of erosion is _________________.

• wind
• ice
• moving water
• snow

The process that breaks down rocks and other materials on Earth's surface is called

• Weathering
• Erosion
• Deposition
• Decomposition

This type of weathering occurs when rock is physically broken down into smaller pieces of rock.

• mechanical weathering
• chemical weathering

This type of weathering occurs when rocks weaken then break down due to chemical changes in the composition of the rock.

• mechanical weathering
• chemical weathering

These rocks were made smooth by wind blowing smaller rock particles across their surface.  This is an example of:

• ice wedging
• chemical weathering
• acid rain
• abrasion

The definition of weathering is _______________________.

• the carrying away of rock
• the leaching of rock
• the breaking down of rock
• the permeability of rock

What caused this rock to break apart?

• ice
• plant
• wind
• rain

The process by which small pieces of rocks and soil are carried away to new locations is called...

• deposition
• erosion
• weathering
• faults

Wind blasting sand at rock and carving out caves is an example of:

• Weathering
• Erosion
• Deposition

Wind blowing sand from one location to another is an example of:

• Weathering
• Erosion
• Deposition
