Revision erosion and deposition

Which way do sand dunes move?

• up & down
• to the west
• toward the sea
• in the direction of the wind

The process of sediment being dropped off in a new place is called

• Abrasion

• Erosion

• Deposition

• Weathering

Small, broken down pieces of rock are called

• sedimentary rock

• sediment

• smaller rocks

• crumbs

Waves wash sand onto land until a beach is formed

• Mechanical Weathering
• Chemical Weathering
• Erosion
• Deposition

The natural chemical or physical processes that breaks down rock on Earth's surface.

• weathering
• erosion
• deposition
• jackhammering

Weathering is the process of -

• Moving sediment from one place to another

• Dropping or leaving sediment in a location

• Breaking down rocks into sediment

Select the answer that shows the order of events a rock goes through.

• erosion, weathering, deposition
• weathering, erosion, deposition
• deposition, weathering erosion
• erosion, deposition, weathering

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

• mechanical weathering
• chemical weathering
• erosion weathering
• deposition

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
• erosion weathering
• deposition

Exposure to rain and oxygen causes the metal minerals in rocks to rust and fall apart.  This is an example of:

• mechanical weathering
• chemical weathering
