| Term | Definition |
|---|---|
| earth system | is all of the matter, energy, and processes within Earth’s boundary. |
| geosphere | is the mostly solid, rocky part of Earth. |
| hrydrosphere | is the part of Earth that is liquid water |
| cryosphere | is made up of all of the frozen water on Earth. |
| atmosphere | atmosphere. This mixture is most often referred to as air. |
| biosphere | is made up of living things and the areas of Earth |
| Temperature | is a measure of the average kinetic energy of particles |
| Thermal energy | is the total kinetic energy of particles |
| thermal expansion | 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 temperatures. |
| Radiation | is the transfer of energy as electromagnetic |
| Convection | is the transfer of energy due to the movement of matter |
| 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. |
| global winds. | As shown at the right, the major global wind systems are the polar easterlies |
| 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 winds | are the movement of air over short distances. They can blow from any direction, on the feature of the area |
| upwelling | The deep water contains nutrients, such as iron and nitrate. |
| water cycle | Rain, snow, and hail fall on the oceans and land because of gravity. |
| Evaporation | occurs when liquid water changes into water vapor. |
| transpiration | About 10% of the water in the atmosphere comes from transportation |
| sublimation | sublimation can happen when dry air blows over ice or snow, |
| condensation | is the change of state from a gas to a liquid |
| Precipitation | is any form of water that falls to Earth from clouds. Three common kinds of precipitation |
| energy budget | is a way to keep track of energy transfers into and out of the Earth system. |
| air pressure | s the measure of the force with which air molecules push on an area of a surface |
| thermosphere | is the uppermost layer of the atmosphere |
| mesosphere | is between the thermosphere and stratosphere. |
| stratosphere | is between the mesosphere and troposphere |
| troposphere | is the lowest layer of the atmosphere. |
| ozone layer | is an area in the stratosphere, 15 km to 40 km above Earth’s surface |
| greenhouse effect | is an area in the stratosphere, 15 km to 40 km above Earth’s surface |
