The creation of igneous rock from magma is dependent on the cooling rate of the magma. Some igneous rocks form almost instantaneously, and others take hundreds of thousands of years. So igneous rock could be the youngest of the three rock types at any given point in time.

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 layer of the earth is composed of igneous metamorphic and sedimentary rock?
The crust.
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
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.
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.
What is the most common type of rock on earth's surface?
Sedimentary Rocks. 75% of rocks exposed to the surface are sedimentary.
How does the volume of sedimentary rocks in Earth's crust compare with the volume of igneous rocks in the crust?
75% Igneous 5% Sedimentary
Which came first sedimentary igneous metamorphic rocks?
Metamorphic rock would probably have been the first rock type formed after the initial formation of the first igneous rock. Sedimentary rock formation relies on weathering and erosion, whereas metamorphic rock can be created by heat and pressure. It's likely that rock was metamorphosed before weathering existed .
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.
Which rocks would be formed above the surface of the earth?
Extrusive igneous rocks, some sedimentary rocks
What are the kinds of earth rocks on earth?
The kinds of rocks on earth are Igneous, Sedimentary, and Metamorphic.
What types of rocks are found on the earth?
igneous, metamorphic, and sedimentary
Which is older igneous or sedimentary?
Neither. You can get sedimentary rocks that are older than igneous rocks, or igneous that are older the sedimentary rocks. However, igneous rocks are formed from magma within the earth's crust, or as it extrudes onto the surface, while sedimentary rocks are formed from the erosion and redeposition of existing rocks, so generally in the life cycle of a rock the igneous form would come first.
What is the oldest rock in earth?
Igneous Rock
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 is the earths crust made of?
The crust of the Earth is made of sedimentary, metamorphic, and igneous rock.
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
