Match the following Earth layers with their descriptions:
geosphere = the solid part of the Earth that consists of all rock crust = the Earth's thin outer layer composed almost entirely of light elements mantle = the layer of rock below the surface, makes up 64% of the mass of the Earth core = Earth's innermost layer, composed of the densest elements

Match the following terms to their descriptions:
lithosphere = the solid, outer layer of the Earth that consists of the crust and the rigid upper part of the mantle asthenosphere = the solid, plastic layer of the mantle beneath the lithosphere that flows very slowly and allows tectonic plates to move tectonic plate = huge pieces of the lithosphere erosion = the removal and transport of surface material

Study Notes
Earth Layers Matching
- Crust: The outermost layer of the Earth, characterized by solid rock and varying thickness.
- Mantle: Located beneath the crust, largely composed of semi-solid rock that flows slowly over geological time.
- Outer Core: A liquid layer composed mainly of iron and nickel, responsible for Earth's magnetic field.
- Inner Core: The innermost layer, a solid sphere primarily made of iron and nickel, experiencing extreme pressure and temperature.
Atmospheric Layers Matching
- Troposphere: The lowest layer where weather occurs, extending from the Earth's surface to about 8-15 km altitude.
- Stratosphere: Contains the ozone layer, situated above the troposphere and extending to about 50 km altitude.
- Mesosphere: The middle layer of the atmosphere, where temperatures decrease with altitude and meteors burn up.
- Thermosphere: A high-altitude layer with very thin air, where temperatures rise significantly, often exceeding 1,000°C.
- Exosphere: The outermost layer of the atmosphere, where atmospheric particles are sparse and can escape into space.
General Matching Terms with Definitions
- Lithosphere: The rigid outer part of the Earth, consisting of the crust and upper mantle.
- Asthenosphere: A semi-fluid layer beneath the lithosphere that allows tectonic plates to move.
- Hydrosphere: All water components on Earth, including oceans, rivers, and glaciers.
- Biosphere: The global sum of all ecosystems, encompassing all living organisms and their environments.
