Question | Answer |
---|---|
process by which new rock is formed from old rock material | rock cycle |
the process by which water, ice, heat, and wind act to break down rocks | weathering |
the process by which particles of rock are removed from their source and transported by the flow of water and the actions of gravity, wind, and ice | erosion |
the process by which water, ice, wind, and gravity drop newly formed sediments | deposition |
the process by which regions of Earth's crust are raised to a higher elevation | uplift |
when mountains form due to the eruption of molten rock onto Earth's surface, adding material to Earth's surface | volcanism |
the bending of rock layers due to stress in Earth's crust | folding |
the breaking of rock layers due to stress in Earth's crust | faulting |
a soft layer of the mantle on which tectonic plates move; made of solid rock that, like putty, flows very slowly | asthenosphere |
the hard, outermost layer of the earth; made up of the crust and the rigid, upper part of the mantle | lithosphere |
outermost and thinnest layer of the Earth | crust |
large slabs of lithosphere that move around on the asthenosphere | tectonic plates |
any naturally forming solid matter with a crystal structure | mineral |
ways to test minerals | color, hardness, luster, streak |
all of the ecosystems on Earth; the part of Earth where life exists | biosphere |
a mixture of gases that surrounds a planet, such as Earth | atmosphere |
first two layers of Earth's atmosphere | troposphere and stratosphere |
