(kəm-pāk'shən) The process by which the porosity of a given form of sediment is decreased as a result of its mineral grains being squeezed together by the weight of overlying sediment or by mechanical means. ]]> 2018-01-30 18:43:37 UTC https://padlet.com/3039131/x8d1wy76w828/wish/226261804 3039131 https://padlet.com/3039131/x8d1wy76w828/wish/226262588 A metamorphic rock is a type of rock which has been changed by extreme heat and pressure. Its name is from 'morph' (meaning form), and 'meta' (meaning change). The original rock gets heated (temperatures greater than 150 to 200 °C) and pressured (1500 bars). This causes profound physical and/or chemical change.]]> 2018-01-30 18:44:53 UTC https://padlet.com/3039131/x8d1wy76w828/wish/226262588 3039131 https://padlet.com/3039131/x8d1wy76w828/wish/226263443 magma definition.

Sedimentary rocks are often deposited in layers, and frequently contain fossils. Note : Limestone and shale are common sedimentary rocks.

Subduction is a geological term for one of Earth's tectonic plates sinking under another. When this happens, we can get earthquakes, volcanoes, and a recycling of Earth's rocks.
