Weathering & Erosion
100
A physical feature on earth's surface.
What are Landforms?
100
This theory explains how forces deep within Earth can cause ocean floors to spread and continents to move.
What is the Theory of Plate Tectonics?
100
An opening in Earth's crust.
What is a Volcano?
100
This occurs when huge slabs of Earth's crust suddenly move.
What is an Earthquake?
100
This happens when water, air or other substances react with rocks, soil or building materials to change their chemical composition.
What is Chemical Weathering?
200
A small river or stream.
What is a Tributary?
200
A scientist who uses rocks to learn about the history and structure of Earth.
What is a Geologist?
200
Hot liquid rock that is still underground.
What is Magma?
200
The point deep within the Earth where the slipping begins along the fault.
What is the Focus?
200
This happens when loose bits of rock and soil formed by weathering are moved from one place to another.
What is Erosion
300
The layer of Earth's core that is made up of liquid metal.
What is the Outer Core?
300
Fossils, age of mountains, types of mountains and shapes of coastline are all evidence of this theory.
What is Continental Drift?
300
Underground dome shaped magma formation which can raise rock layers above it.
What is a Laccolith?
300
The point at the Earth's surface directly above the focus.
What is the Epicenter?
300
The process through which weathered rock is moved from one place to another.
What is Erosion?
400
All of Earth's liquid and solid water including the oceans, lakes, rivers, glaciers and ice caps.
What is The Hydrosphere?
400
Deep cracks in the Earth's crust.
What is a Fault?
400
Having recently erupted or currently erupted.
What are Active Volcanoes?
400
An instrument that measures and detects waves produced by an earthquake.
What is a Seismometer?
400
The process by which eroded material is dropped off in another place.
What is Deposition?
500
The part of the Earth which contains all living things.
What is the Biosphere?
500
A stationary location in Earth's mantle where magma melts through a tectonic plate.
What is a Hot Spot.
500
A measure of the amount of energy released by an earthquake.
What is Magnitude?
500
This forms when waves pick up sand and deposit it in in the water.
What is a Sandbar?
