Weathering
This process breaks rock into smaller pieces without moving them.
What is weathering?
This process moves sediment from one place to another.
What is erosion?
This process happens when sediment is dropped in a new location.
What is deposition?
Glaciers carve valleys with this distinctive shape.
What is a U‑shape?
Waves do this to coastlines over long periods of time.
What is erode them?
These are the two main types of weathering.
What are mechanical and chemical weathering?
This agent carved the “river” in the demonstration.
What is water?
Deposition occurs when this decreases in water or wind.
What is velocity / energy?
These major Canadian lakes were carved by glaciers.
What are the Great Lakes?
Waves are created when this transfers energy to the water.
What is wind?
This type of weathering happens when water freezes and expands in cracks.
What is freeze–thaw mechanical weathering?
Sediment scraping rock surfaces is known as this.
What is abrasion?
This landform forms where a river drops sediment at its mouth.
What is a delta?
When glaciers pull rocks out of the ground, this process occurs.
What is plucking?
This sudden downhill movement of rock and soil is caused by gravity.
What is a landslide?
When plant roots split rocks apart, this type of weathering occurs.
What is mechanical weathering?
When rocks collide and become smoother, this process is happening.
What is attrition?
Glaciers leave behind this unsorted mixture of rocks and sediment.
What is till?
This ridge of sediment marks where a glacier once stopped.
What is a moraine?
This force is responsible for all mass movement.
What is gravity?
Warm, wet climates speed up this type of weathering.
What is chemical weathering?
These four forces are the main agents of erosion.
What are water, wind, ice, and gravity?
Wind deposition creates these large hills of sand.
What are sand dunes?
Glaciers reshape landscapes because of this combination of weight and movement.
What is constant scraping under massive pressure?
These dramatic coastal features like arches and stacks are created by wave erosion.
What are coastal landforms? (arches, caves, stacks, cliffs)
