Question | Answer |
---|---|
convergent plate boundary | A region where plates are pushing together and where a mountain range, island arc, and/or trench will eventually form; often a site of much seismic and volcanic activity. |
divergent plate boundary | where two plates are moving apart, magma comes up to create new crust |
earthquakes | sudden movements of Earth's crust followed by a series of shocks |
igneous rock | rock formed by the solidification of molten magma |
mantle | the layer of the earth between the crust and the core |
metamorphic rock | when changes in pressure, temperature, or chemical makeup alter a rock, metamorphism takes place. |
rock cycle | sequence of events in which rocks are formed, destroyed, altered, and reformed by geological processes |
sedimentary rock | rocks fromed from sediment derived not only from rock fragments but also from plant and animal remains |
subduction | a geological process in which one edge of a crustal plate is forced sideways and downward into the mantle below another plate |
transform fault | Area where the earth's lithospheric plates move in opposite but parallel directions along a fracture (fault) in the lithosphere. |
tectonic plates | Sections of the Earth's crust that move due to convection currents. |
trench | a ditch dug as a fortification having a parapet of the excavated earth |
volcanoes | openings in Earth's crust from which molten rock, dust, ash, and hot gases flow or erupt |
lithosphere | the solid part of the earth consisting of the crust and outer mantle |
parent material | material from which a soil is formed, determines composition and properties of the soil |
material from which a soil is formed, determines composition and properties of the soil | the mass of air surrounding the Earth |
