What is one cause of volcanic activity and igneous rock formation?
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.
Which type of rock is formed above the ground by lava?
The general type is extrusive igneous rock.
In what part of the earth do igneous rocks initially form?
It depends on which igneous rocks we are talking about. Igneous rocks are either formed underground from the solidification of magma, or above ground from the solidification of lava. Igneous rocks exist on and in the crust, as well as in the mantle.
What type of rock is formed when magma undergoes crystallization above ground?
Igneous rocks like rhyolite or andesite are formed when magma undergoes crystallization above ground. These rocks cool relatively quickly, resulting in smaller mineral crystals compared to rocks formed from magma crystallizing deep underground.
What types of rocks are formed above ground?
Sedimentary rocks such as sandstone, limestone, and shale are commonly formed above ground. These rocks are typically created through the accumulation and cementation of sediments, often in environments like rivers, deserts, or the ocean. Igneous rocks can also form above ground when magma cools and solidifies on the Earth's surface, forming rocks like basalt and rhyolite.
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.
What kinds of rock are formed by volcanoes?
Extrusive igneous rocks are formed from the solidification of magma above ground.

What rocks are from volcanoes?
Igneous rock is the type of rock most commonly formed from volcanoes. igneous rocks may be formed from the magma underground, or form after the magma has ejected into the air. Underground, they can be formed when magma (molten rock) is trapped in small pockets and cools slowly over time. Above ground, igneous rocks are formed as the lava cools. Metamorphic rocks can be the result of volcanic activity, but they are not formed directly from volcanoes. Metamorphic rocks are the result of intense heat or extreme pressure transforming either sedimentary or igneous rocks, and these stresses can come from volcanic action, though that is not always the case.
Is igneouse rocks in the ground or above?
Igneous rocks can be found both in the ground and above ground. Igneous rocks form from the cooling and solidification of magma or lava, which can happen below the Earth's surface (intrusive igneous rocks) or on the surface (extrusive igneous rocks).
Where is the igneous rock form?
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 do igneous rock form?
Igneous rocks [fire rocks] 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, and 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. Examples of igneous rocks are granite, scoria, pumice, obsidian and basalt.
When is igneous rock formed?
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.
When molten rock undergoes crystallization above ground what type of rock results?
Extrusive igneous rock is the result of above ground crystallization.
Can igneous rock be formed above or below ground?
Yes, igneous rocks can be formed both above and below the ground. When molten rock solidifies beneath the Earth's surface, it forms intrusive igneous rocks like granite. If molten rock reaches the Earth's surface and cools rapidly, it forms extrusive igneous rocks like basalt.
Is igneous rock that cooled above ground larger then being cooled under ground?
no
What rock types are formed above ground?
Extrusive igneous rocks and some sedimentary rocks are formed above ground.
