What kind of mineral does magma form when it cools?
When magma cools, it forms igneous rock.
What kind of texture does igneous rock have when it cools rapidly?
coarse texture
What kind of rock is formed when magma or lava cools and hardens?
Igneous rock is formed.
What kind of rocks are formed when the magma cools beneath earth's surface?
Intrusive igneous rock.
What kind of rock forms from magma that cools below the earth's surface?
Intrusive Igneous Rock.
What kind of rock forms when magna cools and solidefies in the Earth?
It depends on the composition of the magma, how quickly it cools and crystalises, the temperature and pressure of the original melt.
What kind of rocks are formed when the magma cools on the earth's surface?
Extrusive igneous rocks such as basalt or rhyolite.
Where did gabbro come from?
Gabbro forms from a magma that is rich in iron and magnesium, and poor in silica (quartz). The magma cools and crystallizes deep below the earth's surface. Gabbro is from the same kind of magma as basalt and diabase, but because it cools more slowly, it develops larger crystals.
What kind of rock forms from magma?
Igneous rocks form from magma as it cools and solidifies. Examples include granite, basalt, and obsidian.
Does magma beneath the surface cool fast?
Magma beneath the surface typically cools slowly, allowing for the formation of large crystals. This slow cooling process is known as intrusive or plutonic cooling. In contrast, lava that reaches the surface cools much more quickly due to exposure to lower temperatures and can form smaller crystals or glassy textures.
Extrusive and intrusive rocks are kind of what Rocks?
Extrusive and intrusive rocks are types of igneous rocks. Extrusive rocks form from lava that cools quickly on the Earth's surface, resulting in fine-grained textures, while intrusive rocks form from magma that cools slowly beneath the surface, leading to coarse-grained textures. Both types are primarily composed of minerals like quartz, feldspar, and mica, and they play a crucial role in understanding volcanic activity and Earth's geological history.
When magma cools quickly what kind of txture or crystals dose that rock have?
A mixture of all types of grains or sizes of ctystals.
