| The Troposphere is the | lowest layer of the atmosphere |
| The Stratosphere comes from the | Latin to spread out |
| The temperature increases with the | altitude in the Thermosphere |
| The stratum that is in the middle | Mesosphere |
| This layer is ionized by solar radiation | Ionosphere |
| Subjected to solar wind | Exosphere |
| The tropical rainforest has more kinds | of trees than any other biome |
| The majority of outgoing infrared radiation | is abosorbed by greenhouse gases |
| Adiabatic implies a change in temperature | without gain or loss of heat from outside the air parcel |
| Cold ocean currents flow from | the high latitudes to the low latitudes |
| Warm ocean currents flow from the | low latitudes to high latitudes |
| Sea-floor spreading is part of | vulcanism |
| Obsidian has no crystal structure | due to rapid cooling |
| Viscosity is a measure of | flow rates |
| Pillow lavas formed by the rapid surface | cooling of magma is contact with ocean water |
| The Andes Mountains are a good example of | a volcanic arc |
| A composite volcano has a summit crater | composed of alternating layers of ash and lava |
| A shield volcano has very low | viscosity lava |
| A volcanic neck is made up of | hard rock |
| Vulcanism is the movement of | molten rock |
| A dyke is composed of | intrusive igneous rock |
| The asthenosphere is | plastic |
| A batholith is a massive | intrusion of magma |
| Adiabatic heating/cooling is due | to a change in air pressure |
| A compressed gas | heats |
| An expanded gas | cools |
