Weathering, Erosion, Deposition Flashcards
What is weathering?
The process of breaking down rocks and minerals into smaller pieces.
True or False: Weathering can occur without the movement of material.
True
What are the two main types of weathering?
Physical weathering and chemical weathering.
Fill in the blank: ________ weathering involves the physical breakdown of rocks.
Mechanical
What is erosion?
The process by which soil and rock are removed from the Earth’s surface and transported to another location.
Multiple Choice: Which of the following is a cause of erosion?
A) Wind
B) Water
C) Ice
D) All of the above
D) All of the above
What role does vegetation play in erosion?
Vegetation helps to anchor soil and reduce erosion.
True or False: Deposition is the process of material being laid down after being transported.
True
What is the primary agent of erosion in river systems?
Water
Fill in the blank: The accumulation of sediment in a new location is known as ________.
Deposition
What is chemical weathering?
The process that breaks down rocks through chemical reactions, often involving water and acids.

A) Frost wedging
B) Oxidation
C) Thermal expansion
D) Abrasion
B) Oxidation
What is mass wasting?
The movement of soil and rock down a slope due to gravity.
True or False: Erosion and weathering are the same processes.
False
What is the process by which rocks are worn away by wind called?
Abrasion
Fill in the blank: ________ is the process by which rocks break down due to temperature changes.
Thermal expansion
What is the significance of sedimentary rocks in understanding erosion and deposition?
They provide evidence of past environments and processes of erosion and deposition.
Multiple Choice: Which factor does NOT influence the rate of weathering?
A) Climate
B) Rock type
C) Latitude
D) Time
C) Latitude
What is a delta?
A landform created by sediment deposition at the mouth of a river.
True or False: Glaciers can cause both erosion and deposition.
True
What is the term for the process of soil erosion by water flowing over land?
Sheet erosion
Fill in the blank: ________ erosion occurs in a channelized flow, such as a river.
Channel
What are the effects of human activity on erosion?
Human activities can increase erosion through deforestation, urbanization, and agriculture.
