Where would you find exposed metamorphic rocks?
Because metamorphic rocks from very deep underground, they have to be brought to the surface by some geologic processes before they are exposed. There are many processes that could do this, but the most common is a mountain building event. Mountainous areas often have very large areas of exposed metamorphic rocks.
Igneous and sedimentary rocks are exposed to extreme pressure and heat They will most likely form?
Metamorphic rocks.
Where do metomorphic rocks form?
metamorphic rocks are formed in earths crust not on the surface
Why are metamorphic rocks not common on Earth's surface?
They are formed under the earth's surface.
Are precambrian rocks common?
No. Precambrian rocks are exceptionally rare. That period ended 570 million years ago, and the oldest rocks on the surface of the Earth are in the Laurentian Range, which runs from Southern Quebec down into Texas and Mexico.
Are all rocks sedimenary rocks?
no.there areigneous rocks and metamorphic rocks as well.nevertheless about 95% of all rocks exposed on the earths surface are sedimentary.

How do you change sedimentary rocks into metamorphic rocks?
Sedimentary rocks could become metamorphic rocks if they are exposed to extreme heat and pressure deep in the Earth's crust. The rocks could come to the surface by volcanic activity or rising magma.
Where might a metaphoric rock form?
Metamorphic rocks form when existing rocks are exposed to heat and pressure deep within the Earth's surface
What happens to rocks that are pushed under earth's surface and become hotter and experience more pressure?
They become exposed to deformation in a process called metamorphism, and become metamorphic rocks.
Why do metamorphic rocks often formed deep under the surface of the earth?
Metamorphic rocks are often found deep under the earth's surface because metamorphic rocks form from heat and pressure. Therefore, they form while they are under the earth's surface.
Where are the metamorphic rocks used in the animal kingdom?
Answer On the surface.
What happens each time a metamorphic rock is exposed to extreme heat and pressure?
Metamorphic Rock Metamorphism means to change form; this is exactly what metamorphic rocks do. This paper will take a look at the Earth's rock cycle to examine exactly where the metamorphic rock fits into it. It will also look at how metamorphic rocks are formed and the relationship between metamorphic rocks and igneous rock and sedimentary rocks. This paper will examine the geological characteristics and materials of metamorphic rocks, and examine some examples of metamorphic rocks and will describe mineral composition of some examples and explain its economic uses. The Rock Cycle The rock cycle helps people to understand the starting point of the igneous, sedimentary, and metamorphic rocks. In addition to explaining how each of the rocks are connected through the process. The rock cycle explains to us how the Earth assists in changing one type of rock into another type of rock. The process begins when magma, found from beneath the Earth's surface or from a volcano, cools and crystallizes. This process forms rocks called igneous rocks. When an igneous rock is exposed to weathering and erosion and compacted by the weight of the groundwater, which is otherwise known as lithification, it creates a sedimentary rock. When sedimentary rocks are buried deep within the Earth and evolve into mountains or are exposed to extreme pressure and intense heat it will then turn into the last cycle of rock, the metamorphic rock. Metamorphic rocks can even evolve from other metamorphic rocks. How Metamorphic Rocks Are Formed Within the Rock Cycle Metamorphic rocks are created when they are exposed to extreme heat, pressure, and chemicals. Rocks are usually exposed to extreme heat, pressure, and chemicals at the same time. Metamorphism occurs in one of two situations, contact metamorphism or regional metamorphism. Contact metamorphism occurs when a rocks experience a rise in temperature when it is exposed to magma. Heat is the most important source of metamorphism because... [continues]
What is causing the breakdown of sedimentary rocks?
Sedimentary rocks, when exposed on the surface, is exposed to weathering.
Igneous and sedimentary rocks are exposed to extreme pressure and heat They will most likely form?
Metamorphic rocks.
Where do metomorphic rocks form?
metamorphic rocks are formed in earths crust not on the surface
Can sedimentary rocks and igneous rocks change into metamorphic rocks?
By them being boroken down (sediment) then exposed to great pressure.
