The solid part of the Earth that consists of all rock, as well as the soils and loose rocks on Earth's surface
Earth's thin outer layer, composed almost entirely of light elements.
the layer beneath the crust, makes up 64 percent of the mass of the Earth
Earth's innermost layer, composed of the densest elements. It has a radius of approximately 3,400 km.
a cool, rigid layer, 15 km to 300 km thick, that includes the crust and uppermost part of the mantle.
the layer beneath the lithosphere. The asthenosphere is a plastic, solid layer of the mantle made of rock that flows very slowly and allows tectonic plates to move on top of it.
parts of the lithosphere that float around on the mantle
The removal and transport of surface material
A machine that measures the power of earthquakes
a mixture of gases that surround the Earth
extends to about 18 km above Earth's surface. Almost all of the weather occurs in this layer
extends from about 18 km to an altitude of about 50 km. Temperatures rise as altitude increases in the stratosphere
The atmospheric layer farthest from Earth's surface; nitrogen and oxygen absorb solar radiation, which results in temperatures above 2,OOO°C
a molecule made up of three oxygen atoms. Almost all the ozone in the atmosphere is concentrated in the ozone layer in the stratosphere.
the transfer of energy across space and in the atmosphere
the flow of heat from a warmer object to a colder object when the objects are placed in direct physical contact
the transfer of heat by air currents
the process in which gases trap heat near the Earth
The pull forced upon smaller objects by a larger object due to its mass
The continuous movement of water into the air, onto land, and then back to water sources
the process by which liquid water is heated by the sun and then rises into the atmosphere as water vapor
water vapor forms water droplets on dust particles
droplets of water falling from the sky in some form
the concentration of all the dissolved salts water contains
a hiyer about 300 to 700 m deep where the temperature falls rapidly with depth
A little more than 3 percent of all the water on Earth
The surface of the land where water enters an aquifer
the narrow layer around Earth's surface in which life can exist
