What is delta
100
This is the downhill movement of dry soil due to gravity.

When sediments, soil and rocks are added to a landform or land mass
What is deposition
200
The physical break down of rocks into smaller pieces.
What is mechanical weathering?
200
The area drained by rivers and its tributaries
What is drainage basin.
200
This is the movement of wet soil downhill due to gravity.
What is mudlside
200
This occurs when soil moves slowly downhill due to gravity.
What is creep.
200
________a tiny groove in the soil after a rain.

When oxygen reacts with minerals changing them into iron oxide. Rust appears
What is oxidation
400
The primary force behind all mass movements
What is gravity
400
The difference between physical and chemical weathering is: A. Physical weathering just breaks things apart and chemical weathering changes the rocks forever.
B. Physical weathering breaks things apart and chemical weathering burns rocks with chemicals.
What is A
400
Wind blasting sand at rock and carving out arches is an example of this.
What is weathering or abrasion
400
a channel in the soil and has water in it only after a rainstorm
What is gully
500
When rocks peel off the outer layers (like peeling an onion)
What is exfoilation
500
The number one agent of erosion
What is water.
500
The difference between erosion and deposition is:
a. erosion moves sediment from one place to another and deposition is a physical feature on the Earth.
b. deposition is the process of dropping , or depositing , sediment in a new location and erosion is the process of moving sediment from one place to another.
What is b
500
The sudden movement of rock down a hill be gravity.
What is slump
