Why does earth have more sedimentary rock than metamorphic rock or igneous rock?
Most Earth rock is igneous or metamorphic even though visible surface bedrock is mostly sedimentary. Of the total Earth rock volume, only a tiny fraction is sedimentary.
Is granite is a igneous sedimentary or metamorphic?
the granite melts into lava then cools becoming igneous. it erodes into sediment and then gets compressed into a sedimentary rock. the sedimentary rock becomes metamorphic with heat and pressure deep within Earth
How can metamorphic become igneous rock?
Metamorphic rock can melt under the surface of the earth, and the harden into an Igneous rock. As an Igneous, it could crystalize, or break down into sediment where it can become either Igneous or Sedimentary.
Where does sedimentary rock come from originally?
A sedimentary rock is made from the products of the erosion of other rocks. These could be igneous, sedimentary or metamorphic rocks. If you wish to know the original rock from which sedimentary and metamorphic rocks came from, you have to go back to when the Earth formed. In this case, the answer would be an igneous rock.
Can pebbles change into igneous metamorphic and sedimentary rocks?
No. It's too late.Unless it gets eroded itself and eventually forms layers of sediment which may then get turned into rock.
What are the characteristics of Earth's crust?
the source of resources necessary for the survival of living things
What are the the three classes of rocks?
There are three types of rock on the face of the Earth. The three rocks are sedimentary, metamorphic, and igneous.
What types of rocks are found on the earth?
igneous, metamorphic, and sedimentary
How many rocks are on the earth?
the three major rocks are igneous, sedimentary, and metamorphic rock. igneous- volcanic rocks sedimentary- rocks with layers on top metamorphic- rocks that formed to another rock
What percentage of Earth's crust is metamorphic rock?
According to 118 118, metamorphic rocks make up about 85% of the earth's Continental crust. According to wiki.answers, 75-80% of the earth's surface is composed of sedimentary rock. 20-25% left to be composed of igneous and metamorphic rock.
What are the kinds of earth rocks on earth?
The kinds of rocks on earth are Igneous, Sedimentary, and Metamorphic.
What is the earths crust made of?
The crust of the Earth is made of sedimentary, metamorphic, and igneous rock.
How did metamorphic rocks get to be on the earth today?
Metamorphic rocks are older sedimentary, igneous, and metamorphic changed by pressure and temperature.
Why does earth have more sedimentary rock than metamorphic rock or igneous rock?
Most Earth rock is igneous or metamorphic even though visible surface bedrock is mostly sedimentary. Of the total Earth rock volume, only a tiny fraction is sedimentary.
What 3 different types of rock are formed on Earth?
igneous metamorphic and sedimentary
What are the 3 type rocks?
Metamorphic, Igneous, and Sedimentary. Sedimentary is produced by river sediments compacted into hard rock by years of pressure. Igneous rock is formed by lava cooling down when it reaches the surface. Metamorphic rock comes from Igneous, Sedimentary, or other Metamorphic rocks and is defined as rock that has been changed from some other rock, called a protolith, by years of heat and pressure beneath the Earth's surface.
What percentage of earth's interior is composed of igneous and metamorphic rock?
The "earth's interior" is thought to be composed of magma and, at the core, molten iron and perhaps some nickel. If we look out on the crust of the earth, some 75-80% of the surface of our planet is composed of sedimentary rock. That leaves some 20-25% left to be composed of igneous and metamorphic rock.
