Which types of rocks are formed above ground?
Extrusive igneous rocks are one type of rocks that can be formed above the ground. Sedimentary rocks can also be formed above the ground.
What does igneous rock form from?
Igneous rocks are called fire rocks and are formed either underground or above ground. Underground, they are formed when the melted rock, called magma, deep within the earth becomes trapped in small pockets. As these pockets of magma cool slowly underground, the magma becomes igneous rocks.Igneous rocks are also formed when volcanoes erupt, causing the magma to rise above the earth's surface. When magma appears above the earth, it is called lava. Igneous rocks are formed as the lava cools above ground.
What is the difference between igneous rock that cools above and igneous rock that cools below ground?
That depends on where it cools. Igneous rock forms from magma or lava (there's a difference!) cools and hardens. Extrusive igneous rock forms above the earth's crust, like when the lava from a volcanic eruption hardens. Intrusive igneous rock cools inside the earth when conditions change and the area around the magma cools allowing the magma to cool.
What type of rock can form deep below earths surface or above?
igneous
How does the age of a rock layer compare with an igneous intrusion that is through it or an igneous rock extrusion above it?
If it is above it, the rock layer came after the intrusion. if the intrusion went through the rock layer is older because they layer had to be there in order for the intrusion to go through.
Can igneous rock be formed above or below ground?
It is formed both- above ground (as extrusive igneous rocks) or below ground (as intrusive igneous rocks).
Why do igneous rocks stick up above the ground?
Softer rock is originally around the igneous rock but the soft rock has eroded making the igneous rock visible and above ground level.
When molten rock undergoes crystallization above ground what type of rock results?
Extrusive igneous rock is the result of above ground crystallization.
Is igneous rock that cooled above ground larger then being cooled under ground?
no
What is the theory of igneous rock?
Igneous rock is formed from solidification of magma either above or below ground.
What igneous rocks cool above ground?
Etrusive igneous rocks such as pumice, basalt, andesite and rhyolite.
What types of rocks are formed above ground?
Extrusive igneous rocks and some sedimentary rocks are formed above ground.
What rock types are formed above ground?
Extrusive igneous rocks and some sedimentary rocks are formed above ground.
Which types of rocks are formed above ground?
Extrusive igneous rocks are one type of rocks that can be formed above the ground. Sedimentary rocks can also be formed above the ground.
Is all igneous rock formed by volcanoes?
No. Igneous rock is simply the solid substance left when magma or lava hardens, above ground or below ground.
How do geologists classify igneous rock?
Geologists classify rocks by where they are formed; above ground or under ground
When molten rock undergoes crystallization above ground what type of rock result?
Extrusive igneous rock is the result of above ground crystallization.
