| Term | Definition |
|---|---|
| Earth system | Are all of the matter, energy, and processes within Earth's boundary |
| geosphere | Is the mostly solid, rocky part of Earth if extends from the center of Earth to the surface of Earth |
| hydrosphere | The part of Earth that is liquid water ninety-seven percent of all of the water on Earth is the salt water found in the oceans |
| cryosphere | Is made up of all of the frozen water on Earth therefore, all of the ice, sea glaciers, ice shelves and icebergs are a part |
| atmosphere | Is mostly made of invisible gases that surround Earth the atmosphere extends outward about 500 to 600 km |
| biosphere | Is made up of living things and the area of Earth where they are found |
| energy budget | A way to keep track of energy transfers into and out of the Earth system |
| air pressure | Is the measure molecules push on an area of a surface |
| thermosphere | In the uppermost layer of the atmosphere the temperature increases as altitude increases because gases. |
| mesosphere | Between the thermosphere and stratosphere in this layer, the temperature decreases as altitude increases |
| stratosphere | Is between the mesosphere and troposphere in this layer, temperature decreases as latitude increases |
| troposphere | Is the lowest layer of the atmosphere. Although temperatures near Earth's surface vary greatly, generally |
| ozone layer | Is an area in the tratosphere, 15 km to 40 km above Earth's surface, where ozone is highly concentrated. |
| greenhouse effect | Is the process by which gases in the atmosphere, such as water vapor and carbon dioxide, absorb and give off infrared radiation |
| temperature | A measure of the average kinetic energy of particles the faster a particle moves, the more kinetic energy it has |
| thermal energy | The total kinetic energy of particles a teapot full of tea at a high temperature has more thermal energy than a teapot full of tea |
| thermal expansion | Most substances on Earth expand when they become warmer and contract when they become cooler |
| heat | Is the energy that is transferred between objects that are at different temperature |
| radiation | Is the transfer of energy as electromagnetic waves radiation can transfer energy between objects that are not in direct contact |
| convection | The transfer of energy due to the movement of matter as water warms up at the bottom of the pot, some of the hot water rises |
| conduction | Is the transfer of energy from one object to another object through direct contact |
| wind | The greater the differences in air pressure, the faster the air moves |
| Coriolis effect | This effect is most noticeable over long distances because each point on Earth makes on complete rotation every day, points |
| global wind | As shown at the right, the major global |
| jet stream | Are narrow belts of high-speed winds that blow from west to east, between 7 km and 16 km above Earth's surface |
| local wind | Are the movement of air over short distances |
| ocean current | Ocean currents that occur at or near the surface of the ocean |
| surface current | Most surface currents reach depths of above 100 m, but some go deeper |
| deep current | Are caused by differences in water density |
| convection current | Is movement of water that results from density differences |
| upwelling | The deep water contains nutrients, such as iron and nitrate |
