Sedimentary rocks form on the Earth's crust, and can form metamorphic rocks when buried. Igneous rocks form under the surface, or when liquid magma reaches the surface as lava.
Sedimentary Rocks. 75% of rocks exposed to the surface are sedimentary.
because metamorphic rocks transform at certain temperatures and pressures and knowing this we can gauge how hot it is a certain depth in the earth.
Because the rocks underground clash together and they are big rocks so it is going to shake and move
All rocks can be susceptible to weathering, or erosion by natural (and sometimes manmade) forces. It does not matter if it is sedimentary, igneous, or metamorphic. Intrusive rocks, below the surface of the Earth's crust, are not as weathered as rocks above the surface (extrusive), which are stripped of sediment and particles more frequently due to water, wind, etc.
I think it is "extrusive Igneous rock". Well, the magma,the hot liquid earth material which flows out through a vent(ways or cracks in the earth's crust), if on coming over to the surface of the earth, cools or solidifies, it is called "extrusive rock". If the magma, cools before coming over to the surface of the earth it is called "intrusive rock". the rocks formed this way are generally Igneous rocks. More detailed answer may follow.
Sedimentary
Magma is under the surface of Earth's crust. Rocks on earth's surface are well ... on Earth's surface. Magma is also molten rock, not solid rock like the rocks on earth's surface.
igneous rocks that form on earth's surface
earth origin
from earth surface ^_^
They are formed under the earth's surface.
No. Intrusive rocks form when liquid magma "squirts" into the crust and hardens. Igneous rocks that form at the earth's surface are called extrusive rocks.
Uplift replaces rocks on Earth's surface lost the process of erosion.
Weathering breaks down rocks on the Earth's surface by wind, rain, or ice.
Uplift replaces rocks on Earth's surface lost the process of erosion.
Intrusive igneous rocks form from cooled magma below Earth's surface.
Apart form the Oceans the earths surface is made of rocks.
