Mr. Biando's Lab - Changes in Climate
| Definition | Term |
|---|---|
| A long period of climate cooling during which ice sheets cover large areas of the Earth's surface; during a glacial period. | Ice Age |
| A period of time in which enormous sheets of ice advance (grow larger) and cover more surface area. | Glacial Period |
| A period of time in which sheets of ice begin to melt and sea levels start to rise (increase). | Interglacial Period |
| A scientific explaination about how ice ages are caused by a change in the of the Earth's tilt of it's axis and the shape of it's orbit around the sun. | The Milankovitch Theory |
| One theory that proposes that an ice age happens when all the Earth's continents are positioned closer to the polar regions. | Plate Tectonics |
| A naturally occuring geological process that sends large amounts of dust particles, ash and smoke into the atmosphere which blocks the sun's rays, which causes the Earth to cool. | Volcanic Eruptions |
| When a large piece of rock slams into the Earth from space, it causes debris to shoot into the atmosphere which blocks the sun's rays, which causes the Earth to cool. | Asteroid Impact |
| Every 11 years the sun changes from a solar maximum to a solar minimum which effects the warming of the winds, which in turn affects climate patterns. | The Sun's Cycle |
| A gradual increase in the average global temperature. | Global Warming |
| The warming of the surface and lower atmosphere of the Earth that occurs when carbon dioxide, water vapor, and other gases in the air absorb and trap thermal energy. | Greenhouse Effect |
