Retest on Weathering, Erosion and Deposition

What is weathering?

• occurs when the eroded materials are dropped or laid down

• fragments of weathering rocks

• the process by which rock materials are broken down by the action of physical and chemical process

• the process by which wind, water, ice or gravity transport weathered materials from one location to another

What is sediment?

• occurs when the eroded materials are dropped or laid down

• fragments of weathering rocks

• the process by which rock materials are broken down by the action of physical and chemical process

• the process by which wind, water, ice or gravity transport weathered materials from one location to another

What type of chemical weathering is in the picture shown?

• oxidation

• mosses and lichens

• acid precipitation

What are the two types of weathering?

• oxidation and abrasion

• physical and chemical weathering

• animals burrowing and plant roots breaking apart rocks

The geological process when rocks or sediments move or are transported from one place to another is:

• weathering

• erosion

• deposition

What are glaciers?

• They are winding rivers that carry sediment to a delta

• They are waves that constantly crash against the shoreline.

• are huge masses of ice that move slowly over land.

• They are sand dunes that form from wind depositing sediments.
