Weathering
This process breaks down rocks into smaller pieces at Earth's surface without moving them to a new location.
What is weathering?
This process moves weathered rock and soil from one place to another by water, wind, ice, or gravity.
What is erosion?
This process occurs when sediment carried by water, wind, ice, or gravity is dropped in a new location.
What is deposition?
This feature forms on the outside of a meander where the water moves faster and erosion occurs.
What is a cut bank?
When rainwater reacts with minerals in rocks and changes their composition, this type of weathering is taking place.
What is chemical weathering?
This agent of erosion is responsible for carrying most sediment from mountains to oceans.
What is a river?
When a river slows down and drops sediment at its mouth, it can form this landform.
What is a delta?
The faster-moving water in a river is usually found on this side of a meander.
What is the outside of a bend?
This process happens when water freezes in rock cracks, expands, and causes the rock to break apart.
What is frost wedging?
When wind carries and deposits sand, creating sand dunes, this type of erosion is occurring.
What is wind erosion?
When a river overflows its banks and leaves behind rich soil, it creates this feature.
What is a flood plain?
This feature may form when a meander is cut off from the main river channel.
What is an oxbow lake?
Water freezing and expanding in cracks of rocks is an example of this type of weathering.
What is physical weathering?
Large masses of moving ice that scrape and carry rock across Earth's surface are called these.
What is a glacier?
This curved bend in a river forms as water erodes and deposits sediment along its banks.
What is a meander?
This human activity can increase erosion by removing plants that hold soil in place.
What is deforestation?
This type of chemical weathering occurs when oxygen reacts with iron in rocks, causing them to form a reddish-brown coating.
What is oxidation?
This force causes rocks, soil, and sediment to move downhill during landslides and mudslides.
What is gravity?
This feature forms on the inside curve of a meander where sediment is deposited.
What is a pointbar?
Construction sites often use silt fences and erosion-control blankets to reduce this environmental impact.
What is soil erosion?
