Theory of Plate Tectonics
Changing landforms
Deposition
Water in motion
Glaciers shape the land
100
Plates move towards eachother and collide.
What is convergent boundary?
100
They are large, flat areas often used for agriculture.
What is plains?
100
The dropping of a small sediment
What is deposition?
100
Flat layer of sediment deposited by rivers in flood stage.
What is floodpain?
100
The large ridge of material deposited by a glacier
What is moraine?
200
Plates move away from eachother
What is divergent boundary?
200
Flat, raised areas of land made up of nearly horizontal rocks that have been uplifted by forces within Earth.
What is plateaus?
200
Cannot erode sedioment
What is air?
200
The rapid movement of rock.
What is landslide?
200
A bowl shaped basin formed by erosion at the start of a mountain glacier.
What is cirque?
300
Some plates slide past eachother
What is transform boundary?
300
A triangular deposit of sediment at the mouth of a river.
What is delta?
300
They all wear away materials and carry them off.
What is gravity, ice, wind and water?
300
They erode shorelines
What is oceans, seas, and large lakes?
300
A sharpened peak formed by the glacial action of three cirques on a moutaintop.
What is a horn?
400
Earth's lithosphere interact with eachother
What is theory of plate tectonics?
400
Formed when rock layers are squeezed from opposite sides when forces within Earth push up crust.
What are Mountain's?
400
They are deposited everyday in British Columbia.
What is sediment, mud and rocks?
400
Creates slower changes to the earth.
What is running water?
400
Eroded by glaciers are U-shapedbecause a glacier plucks and scrapes soil and rock from the sides as well as from the bottom.
What are Valley's?
500
The study of the movement of large-scale structural features on Earth's crust
What is tectonics?
500
The movement of rock particals or soil from one place to another.
What is erosion?
500
It's what pulls the sediments down to Earth's surface.
What is gravity?
500
They erode materials.
What is rivers?
500
Wind-blown dust, ash, and atomspheric.
What are the layers made of?
