The breaking down of rock on Earth's surface into smaller pieces.
What is weathering?
100
Wind and water can carry sand and small pieces of rock to new locations. True or False
What is True?
100
Mechanical weathering process that occurs when water freezes in the cracks of rocks and expands, causing the rock to break apart.
What is ice wedging?
100
The difference between weathering and erosion is:
a. weathering causes a quick change in landforms and erosion causes a slow change in landforms.
b. weathering breaks rocks into sediments and erosion moves sediment from one place to another.
What is B?
100
Small pieces that break off of rocks.
What is sediments?
200
Type of weathering where rock is broken down into smaller pieces without changing the chemical properties of the rock.
What is mechanical weathering?
200
Chemical weathering occurs more rapidly in which type of climate?
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?
200
Freezing and thawing, release of pressure, growth of plants, and actions of animals are examples of...
What is mechanical weathering?
300
The process by which weathered rock is picked up and moved to a new place.
What is erosion?
300
Weathering over long periods of time breaks rock into ____________ pieces. (larger or smaller)
What is smaller?
300
Grinding away of rock by other rock particles.
What is abrasion?
300
Name a difference between weathering and erosion.
What is weathering makes things smaller, and erosion moves it?
300
Name 2 agents of erosion.
What is a water, ice, wind, and gravity?
400
Process of breaking down rock through chemical changes.
What is chemical weathering?
400
When the sediment that is being carried is dropped in a new area.
What is deposition?
400
Water can weather rock by:
A. eroding soil
B. by freezing and melting
What is freezing and melting?
400
Name 3 out of the 5 things that cause chemical weathering.
What is water, oxidation, carbon dioxide, living organisms, and/or acid rain?
400
Chemical and mechanical
What are 2 types of weathering?
500
The reaction of rock minerals with oxygen, thus changing the mineral composition.
What is oxidation?
500
When fossil fuels are burnt they release oxides sulphur, carbon and nitrogen into the air. These gases combine with moisture in the air to form sulphuric acid, carbonic acid and nitric acid, making the resulting rainwater more acidic than normal.
What is acid rain?
500
The material moved by erosion is called ___________.
What is sediment?
500
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.
