Atmosphere
|
A mixture of gases that surrounds a planet or moon.
|
|
|
Hydrosphere
|
The portion of Earth that is water.
|
|
|
Biosphere
|
The part of Earth where life exists.
|
|
|
Crust
|
The thin and solid outermost layer of the Earth above the mantle.
|
|
|
Mantle
|
The layer of rock between the Earth's crust and core.
|
|

|
Erosion
|
The process by which wind, water, ice, or gravity transports soil and sediment from one location to another.
|
|
|
Mesosphere
|
The lower layer of the mantle, lies below the atmosphere.

|
|
Lithosphere
|
Earth's rigid, outermost layer.

|
Radiation
|
The transfer of energy as electromagnetic waves.
|
|
|
conduction
|
The transfer of energy as heat through a meterial.
|
|
|
Convection
|
The transfer of thermal energy by the circulation or movement of a liquid or gas.
|
|
|
troposphere
|
Is the atmospheric layer in which we live.
|
|
|
Stratosphere
|
The atmospheric layer immediately above the troposphere.
|
|
|
mesosphere
|
above the stratosphere.
|
|
|
Thermosphere
|
The layer farthest from Earth's surface.
|
|
|
Convection Current
|
The continuous cycle of warm air sinking.
|
|
|
Greenhouse Effect
|
Warms the surface of earth and makes Earth suitablefor life.
|
|
|
Surface Current
|
A horizontal movement of ocean water that is caused by wind and that occurs at or near the ocean's surface.
|
|
|
Deep Currents
|
A streamlike movement of ocean water far below the surface.
|
|
|
Aquifers
|
A body of rock or sediment that stores groundwater and allows the flow of groundwater.
|
|
|
Ocean Currents
|
Contains streamlike movements of water
|
|
|
Rocks Cycle
|
the series of processes in which a rock forms, changes from one type to another, is destroyed, and forms again by geologic processes.
|
|
|
Water Cycle
|
the continuous movement of water between the atmosphere, the land and the oceans.
|
|
|
Carbon Cycle
|
the movement of carbon from the nonliving enviroment into living things and back
|
|
|
Nitrogen Cycle
|
The process in which nitrogen circulates among the air, soil, water, plants, and animals in an ecosystem
|
|
|
Evaporation
|
occurs when liquid water in ocean and on Earth's surface changes to water vapor, a gas
|
|
|
Stomata
|
water vapor is also released into the air through pores.
|
|
|
Traspiration
|
after water vapor is released, it rises into the atmosphere.
|
|
|
Condensation
|
the change in water from a gas to a liquid.

|
Percolation
|
a downward movement of groundwater.
|
|
|
runoff
|
the movement of water over the land surface
|
|
|
Sea-spreading
|
The process by which new oceanic lithosphere forms as magma rises toward the surface and solidifies.
|
|
|
Mid-ocean ridges
|
Are places where sea-floor spreading takes place.
|
|
|
Magnectic reversal
|
When Earth's magnetic poles change places.
|
|
|
continental Drift
|
the hypothesis that states that the continents once formed a single landmass, broke up, and drifted to their present locations.
|
|
|
Pangaea
