2022 Weather Plate T
8th grade Weather & Plate Tectonics Test Review 2022
| Term | Definition |
|---|---|
| divergent | Type of plate boundary in which the plates are separating |
| convergent | Type of plate boundary in which the plates are colliding |
| subduction | When 2 plates collide, and one plate is forced under another |
| fault | A crack in the Earth’s crust |
| geology | The study of the earth; what it is made of and the processes that effect it |
| Thunderstorm | Weather event associated with a cold front |
| mountains | The geologic action of colliding tectonic plates produce these |
| continental drift | The idea proposed by Alfred Wegner |
| islands | The result of a tectonic plate moving over a hot spot or a plume |
| profile | A view or picture from the side |
| Transform | a tectonic plate boundary where the plates slide past one another |
| Pangaea | The name of the supercontinent that may have existed 200 million years ago |
| ridge | A crustal feature formed in the middle of the Atlantic ocean by a divergent boundary |
| folded mountains | A crustal feature formed by the convergence of 2 continental plates |
| harry Hess | The man who discovered that the sea floor was spreading |
| Alfred Wegner | The man who couldn’t show how continents move to support his theory of continental drift |
| Buoyancy | An upward pushing force in all fluids |
| Mesosaurus | prehistoric lizard fossils found in both South America & Africa |
| Air mass | A Large body of air with consistent temperature, moisture and air pressure |
| glossopteris | prehistoric fern fossil found in India and Antarctica |
| Maritime Tropical | Air mass with the lowest pressure |
| lithosphere | The layer of the Earth consisting of its upper mantle and its crust |
| Coriolis effect | Air currents spin clockwise in the Northern and counterclockwise in the southern hemisphere |
| Seismic | The waves produced by an earthquake |
| clear | The type of sky in areas with high air pressure |
| Seismometer | The measuring of earthquake waves |
| Front | The boundary between two air masses |
| Richter | The scale for comparing earthquakes |
| Water | substance that takes a long time to warm up and or cool down |
| Convection | Warmer fluids that are less dense and rising |
| Continental Polar | A cold and dry air mass |
| Gyres | Large circular ocean currents that are bordered by continents |
| Gulf Stream | Large surface current that carries warmer temperatures from Florida to Europe |
| High pressure | Air pressure created by cold, dry air |
| Sea Breeze | Local wind created by strong daytime convection over land next to an ocean |
| Doldrums | low pressure areas with low winds found at or near the equator |
