Second semester for Esps
| Question | Answer |
|---|---|
| Energy resources | sources of usable energy |
| Volume | amount of space an object occupies |
| Fossil fuels | formed from ancient remains of organisms |
| definition of radiation | all forms of energy that travel through space was waves, including the energy that Earth receives from the sun |
| How is Earth's atmosphere heated? | by sun |
| Frequency | the rate at which a vibration occurs that constitutes a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light), usually measured per second |
| Wavelength | the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave. |
| Nonrenewable energy | exist in a limited supply and once used up they are gone forever |
| What are two primary sources of heat in the atmosphere | absorption and sun's rays |
| What forms of radiation can humans see? | Visible light form |
| Why does the amount of water in the air affect the temperature of a region? | Water vapor stores heat |
| What happens to solar energy that reaches Earth's surface? | Can be reflected or absorbed |
| Galaxy | a system of millions or billions of stars, together with gas and dust, held together by gravitational attraction. |
| what effect do collision between molecules have on the molecules? | it warms them |
| as they become heated, mole is a substance do what? | move faster |
| Gas giant | large planet of relatively low density consisting predominantly of hydrogen and helium, such as Jupiter, Saturn, Uranus, or Neptune. |
| parallax | the effect whereby the position or direction of an object appears to differ when viewed from different |
| Melt | from solid to a liquid |
| freeze | change from liquid to solid |
| How is Earth's atmosphere warmed evenly? | by the continuous cycle convection |
| Whys does convection occur? | When liquids or gases are heated unevenly |
| Seasonal variations in temperature occur because of.. | the tilt of Earth's axis |
| Temperatures are higher at the equator because | solar energy is concentrated in a small area |
| Near the equator, the rays of the sun strike the ground at an angle of about..? | 90% |
| What is the primary factor that affects how much solar energy reaches any point on Earth's surface? | latitude |
| Which regions will generally have more moderate temperatures? | Regions receiving ocean winds |
| The transfer of energy as heat from one substance to another by direct contact is called? | conduction |
| Air is a poor conductor because..? | molecules are far apart |
| Conduction heats only the lowest few centimeters of the atmosphere because | air does not come into direct contact with Earth |
| Condense | to change from a gas to a liquid |
| Density | the amount of matter in a certain space |
| boil | change from a liquid to gas |
