Layers and its descriptionsLAYERSHeightTemperatureCharacteristicsCrust100 kmIncreases with depth (200-400C)Solid outermost shell of the planetUpper Mantle670 km500-900CThe rocks in this region are more rigid because of cooler temperature and lower pressures.Lower Mantle2230 kmOver 4000CHot and plastics, higher pressure causes mineral formationOuter core2250 km4400-6100CLiquid and has the density of 11 grams per cubic centimeterInner core1220 kmTheoretically measuredSolid and has a density of 13 grams per cubic centimeterThe earths interior
Uniformitarianism
UniformitarianismCatastrophic processes were not responsible for the landforms that existed on the Eartgs surface.Landscape developed over long periods of time through a variety of slow geologic and geomorphic process.Catastrophism
catastrophismThe earth was of recent creation and had been affected by a series of catastrophic events such as the Biblical Flood.end
