the type of weathering in which rock is physically broken into smaller pieces is called:
mechanical weathering
Processes by which rock, sand, and soil are broken down and carried away by ice, water, wind and gravity is known as:
Erosion
What is deposition?
Process in which sediment is laid down in new locations.
a low area between hills and mountains, often where a river flows
what is a valley?
what is gravity?
Major factor that causes all mass movements
the process that breaks down rock through chemical changes is called:
Chemical weathering
High-energy environments are most likely to deposit which one of the following?
Larger Sediment
What ways can sediment be deposited?
Glaciers
Water
Wind
Gravity
what is a meander?
a loop bend in the coarse of a river
what is a creep?
Most continuous mass movement (happens over a long period of time)
water, oxygen, carbon dioxide, living organisms, and acid rain cause:
Chemical weathering
In a low energy environment such as the middle of a large lake, the most likely sediment size to accumulate is:
Smaller Sediment
What is water deposition?
occurs as water slows down and drops the sediment it was carrying
how is a coastline formed?
erosion by waves
Mass movement where mass of soil is moved all at once is a:
Slump
refers to the wearing away of rock by rock particles carried by water, ice, wind, or gravity is:
Abrasion
Erosion is caused by these forces:
Wind, Water, Ice and Gravity
What formation results when a river deposits sediment and it slows down as it enters a large body of water?
delta
what is a volcano?
Mountain created as liquid rock or ash from inside the earth
What is a mudslide?
rapid downhill movement of water, rock, and soil
How does water mechanically weather rocks?
There are two ways that water can mechanically weather rock: 1. water in streams and rivers carries sediments that cause abrasion; 2. water flows into cracks in rocks where it can freeze and cause ice wedging.
What is deflation?
the process by which wind removes surface materials
Wind picks up sediment from the ground and carries it. As the wind slows down, it deposits the sediment in other places. Which type of sediment will be dropped first as the wind slows?
the heaviest pieces
what is a tributary?
Small river or stream that flows into a larger river or stream; a branch of the river
What is a landslide?
a mass movement where rock and soil move quickly downhill
