Question | Answer |
---|---|
landform processes | changes that occur in landforms |
tidal wave | the "bulge" in the ocean's surface caused by the pull of the moon's gravity, which becomes high tide at each place it travels to |
storm surge | the sudden rise in sea level caused by high winds pushing water toward coastlines |
epicentre | the break point where earth's plates move suddenly, causing an earthquake |
composite cone | a volcano made up of alternating layers of cinders and magma |
shield cone | a volcano built entirely of magma |
plate tectonics | the theory that all the continents were once joined together and are gradually drifting apart |
igneous rock | solidified magma from inside the earth |
metamorphic rock | changed rock |
sedimentary rock | thick beds of sediment that have slowly solidified into rock |
contour lines | lines on a map that connect points with the same elevation |
topographic map | a very detailed map of physical and human features |
elevation | the height above sea level |
cross-section diagram | a diagram that shows the inside of an object, as though you had cut across it |
river system | the whole network of streams and lakes that come together to form one river |
dendritic drainage | the tree-like drainage pattern created if rivers cross a gradual slope over one basic type of rock |
trellis drainage | the rectangular drainage pattern created if rivers flow through alternating bands of hard and soft rock |
greenhouse gases | gases that capture solar radiation, this acts somewhat like a "roof" on the lower atmosphere |
fossil fuels | fuels, such as coal, oil, and natural gas, that are formed from the remains of ancient plants and animals |
global warming | the gradual increase in the temperature of the earth's surface |
solar radiation | energy from the sun |
greenhouse effect | the heating of the earth's surface caused by gases creating a "roof" over the lower atmosphere |
tropical storm | a storm originating in the tropics and marked by high winds and often heavy rain, such as hurricanes, cyclones, and typhoons |
tropical disturbance | a weather phenomenon originating from warm ocean waters as cool air blows into the base of swirling mounds of warm, moist air heated by the sun |
vortex | the rapid, spiralling winds of the tornado |
Doppler radar | electronic soundings that measure the speed and rotation of winds and wind drafts |
polar climate | severe winters and cool summers |
tropical climate | hot temperatures in every season and a lot of moisture |
temperate climate | moderate temperature conditions year round |
air pressure | a measure of the density of air |
desert climate | very dry weather conditions |
maritime climate | warm summers and cool winters |
continental climate | hot summers and cold winters |
mountain climate | cooler than places at lower altitudes; often with heavy precipitation if located near coastlines |
