V1
Deep cracks in the Earth's crust
Fault
The mass of land that forms at the mouth of a river
Delta
List 4 agents of physical weathering:
Ice, water, wind, plants
Wide, flat area
Plain
What causes weathering?
- Weathering is the breakdown of rock over time.
Agents: Wind, water, ice, gravity, plants, & animals.
A deep valley with high, steep sides
Canyon
A mound or ridge of sand
Dune
List 4 agents of erosion:
Wind, Water, Ice, Waves
The process of weathered rock moving from one place to another
Erosion
Describe how weathering, erosion, and deposition are all different.
Weathering is the process of rocks getting broken down into smaller pieces.
Erosion is when that weathered rock is moved from one place to another.
Deposition is when the eroded sediment is deposited in a new location forming new land.
A physical feature on Earth's surface. Vary greatly in shape and size.
Landform
Liquid, molten to rock
Magma
List 4 landforms formed by deposition:
Sand Dune, Delta, Beaches, Sandbar
An opening in Earth's crust where magma can rise up
Volcano
How are canyons formed?
By water, such as river, slowly wearing down rock over a long period of time. As water is constantly flowing over the same rock, it wears down.
A weak spot in the middle of a tectonic plate where magma surfaces. (Forms a volcano)
Hotspot
Land that rises high above the ground
Mountain
What is?a divergent boundary in the middle of the Atlantic Ocean where seafloor spreading occurs
Mid-Atlantic Ridge
The slow process that breaks down rocks into smaller pieces
Weathering
Happens at transform boundaries. As two plates are moving past each other/ sliding against each other, they get stuck. Pressure build up for a long time. When the plates move again and tension is released, it releases an energy that we feel.
A theory that describes how forces deep within the Earth can cause ocean floors to spread and continents to move
Plate Tectonics
Process of eroded materials being dropped off in another place
Deposition
List 4 agents of chemical weathering:
Water, Oxygen, Carbon Dioxide, Living things
Earthquake
What do mountains, earthquakes, and volcanoes have in common?
They all are caused by the movement if Earth's plate.
