How and where are igneous rocks formed?
Igneous rocks are formed on and below the surface of the Earth when lava or magma cools enough to crystallize.
When melted rock cools or hardens on it under earths surface it forms rock?
Igneous rock. Extrusive igneous rock forms at or near the surface, intrusive igneous rock forms below the surface.
What type of igneous rock hardens under the surface?
The type of igneous rock that hardens under the earths surface is called the Intrusive Igneous Rock. Intrusive Igneous Rocks are of two main types, Hypabasal and Plutonic. The plutonic forms at deeper depths.
Intrusive igneous rock forms where?
Intrusive igneous formed due to consolidate of magma within the earth.
Are Extrusive Igneous Rocks Formed On The Earth's Surface?
Yes. Or in the air, or under water, or very near the surface.
What rock type is formed from the slow cooling of magma under the earths surface?
Magma cooling beneath the surface creates intrusive igneous rocks.
Why are igneous rock formed?
They can be formed underground or above ground. Underground, they are formed when melted rock, called magma, deep under the earth's surface is trapped in small pockets. As these pockets of magma cool slowly underground, the magma develops into igneous rocks. Igneous rocks are also formed when volcanoes erupt, causing the magma to rise above the earth's crust. When magma appears above the earth, it is called lava. Igneous rocks are formed as the lava cools above ground.
What is rock that is formed when magma cools under earths surface?
Intrusive igeneus such as basalt
Fuel formed under the earths surface by the decomposition of organic matter is called?
a boat
Is sandstone extrusive?
sedimentary rock are extrusive when the were formed outside land than in the dirt extrusive rocks take less time to form than intusive (formed under ground) becase wind and help it form faster. i hope this is very helpful =)
When melted rock cools or hardens on or under earths surface it forms what kind of rock?
It forms an igneous rock. If it is within the Earth, then it is an intrusive igneous rock (e.g. granite) and if it is erupted onto Earth's surface then it is an extrusive igneous rock (e.g. basalt).
Granite is what type of rock?
Granite is an intrusive felsic igneous rock, having formed under the surface by the slow cooling of magma which had intruded into the crust.
