During the rock cycle what forms when magma cools?
When magma cools you get intrusive igneous rock. Think of other ig words you know. Ignite, ignition they all mean heat. Igneous rocks are formed from rocks that have been heated so much they melt. When they cool they make new, igneous, rocks. If it's magma that cools that means it's still under the earth's crust so the igneous rock is intrusive. If it's lava that cools after flowing down a volcano it's an extrusive igneous rock that's formed.
What are four Mafic Igneous rocks?
The four I know of are: gabbro, basalt, peridotite, and dolerite.
How is an igneous rock created?
Igneous rocks are created when magma cools and solidifies either below the Earth's surface (intrusive igneous rocks) or on the surface as lava (extrusive igneous rocks). The rate of cooling affects the crystal size and texture of the rock, with slower cooling producing larger crystals. Examples of igneous rocks include granite, basalt, and obsidian.
What are the 3 types of rock are in volcanoes?
Igneous rocks exhibit three types of textures: coarse grained (intrusive), fine grained (extrusive), and porphyritic (two-stage solidification of mineral constituents). Chemically, they are categorized as felsic, mafic, or intermediate.
What are the properties of different rock types?
Igneous rocks are formed from cooling and solidifying magma, and can be either intrusive (formed beneath the surface) or extrusive (formed at the surface). Sedimentary rocks are formed from the deposition and solidification of sediment (particles of rocks, minerals, or organic material) over time. Metamorphic rocks are formed from the alteration of existing rock types through heat, pressure, or chemical processes, resulting in a new crystalline structure.

What are 3 ways extrusive and intrusive different?
Intrusive rocks are from the magma INSIDE of the volcano. Extrusive rocks are from the OUTSIDE of the volcano. I don't know 2 other ways but by the way I learned this in 4th grade?!
4 most commenly know igneous rocks?
Granite, Basalt, Gabbro, and Obsidian

What group of rocks does granite belong to?
Granite is classified as an intrusive igneous rock.
Is obsidian an instrusive or extrusive igneous rock how do you know?
Obsidian is an extrusive rock and is formed from rapidly cooling magma. Obsidian is also known as volcanic glass and one can find only sub-microscopic crystals in it. This is because it was cooled too fastly for large crystals to form. If the material that obsidian consists of were an intrusive rock and had a lot of time to cool down, one would find that it would be composed of easily visible crystals.
How are the textures of extrusive and intrusive igneous rocks different?
Extrusive igneous rocks have come to the surface when cooling down. Intrusive igneous rocks stay within the earth. This difference is important. When a magma comes to the surface, it's called a lava. On the surface, the lava will be subject to cooling by wind and water. This will happen fast. When a magma stays inside the earth, it will cool down considerably slower, because it has to radiate it's heat to the rest of the earth. This doesn't go fast because while water and air can flow, rock can't. The texture of an igneous rock has everything to do with the cooling speed. As a magma or a lava cools, it forms crystals. When the cooling happens relatively fast, these crystals do not have a lot of time to grow together, so you will get a lot of small crystals. When the cooling is very slow, the crystals will have more time to grow, and the crystal size will be a lot bigger. Take for instance granite. If you've ever seen it, you know you can see the crystals with the naked eye, because they are very large. Basalt, on the other hand has a very fine structure, you can't see the crystals without magnifying equipment like a microscope. So there you have it: an extrusive igneous rock will have a very fine texture, with small crystal sizes, an intrusive igneous rock will have a very coarse texture, with large crystal sizes.
