100
the thin and solid outermost layer of Earth above the mantle
What is the crust?
100
a wave of energy that travels through the Earth and away from and earthquake in all directions.
What are seismic waves?
100
the theory that explains how large pieces of Earth's outermost layer, called tectonic plates move and change shape.
What is plate tectonics?
100
liquid rock produced under earth's surface; igneous rocks are made from it.
What is magma?
100
a region that has no plant life, long periods without rain, and extreme temperatures; usually found in hot climates.
What is a desert?
200
The layer of rock between Earth's crust and core.
What is the mantle?
200
a movement or trembling of the ground that is caused by a sudden release of energy when rocks along a fault move
What is an earthquake?
200
a block of lithosphere that consists of the crust and the rigid, outermost part of the mantle.
What are tectonic plates?
200
describes magma or igneous rock that is rich in magnesium and iron and that is general dark in color.
What is mafic?
200
a community of organisms and their abiotic, or nonliving, environment.
What is an ecosystem?
300
The central part of the Earth below the mantle.
What is the core?
300
The location within Earth along a fault at which the first motion of an earthquake occurs.
What is a focus?
300
2 tectonic plates slide past one another horizontally and cause strike-slip faults
What are transform boundaries?
300
a vent or fissure in Earth's surface through which magma and gases are passed.
What is a volcano?
300
the largest population that an environment can support at any time given.
What is carrying capacity?
400
the transfer of energy as electromagnetic waves.
What is radiation?
400
the point on earth's surface directly above an earthquake's starting point, or focus.
What is the epicenter?
400
the bending of rock layers due to stress.
What is folding?
400
magma that flows on Earth's surface; the rock that forms when it cools and solidifies.
What is lava?
400
a measure of how hot or cold something is; specifically, a measure of the average kinetic energy of the particles in an object.
What is temperature?
