Wheathering | The process of rock being naturally broken into smaller pieces either physically or chemically |
Erosion | When weathered rocks are removed and transported else where |
condensation | The process of cloud vapour becoming falling rain |
Precipitation | The process of raining which can in the form hail, sleet or snow |
Evaporation | When water is evaporated into the coluds and go fromliquid to gas |
Transform | When two plates scrape up against each other, causing great amounts of frictionand possibly earthquakes |
Converging | When two plates collide and can possibly form mountains |
Diverging | When two plates separate and trenches may be formed. |
Mantle plume | A rising column of molten lava, causing intense and localised volcanism which can also cause a series of small islands |
Continental drift | When all of the earths continents were connected to form one big continent called Pangea. |
Epicenter | The geographic point on the earths surface directly above the focus point |
Focus | The point beneath the earths surface where the slip begins |
Seismograph | An instrument used to measure seismic waves that earthquakes generate |
Richter scale | An instrument used to measure the size of an earthquake |
Physical weathering | Rock being broken up without the minerals in it changing |
Chemical weathering | When the minerals are changedby chemical reaction |
Convection current | Circuler currents inside the earths mantle and crust |
Subduction | Force of gravity pulls the heavier tectonic plate down and forces the lighter one above |
