What is a factor that controls grain size in igneous rock?
It depends on if it is intrusive or extrusive. If it is an intrusive rock, it is formed when magma hardens under the earth and has a larger grain size. If it is an extrusive rock, it is formed when lava hardens on the earth's surface and has a smaller grain size.
What rocks found in the mantel?
The igneos rock is the most usual rock to form.
How are igneos formed?
From lava that came from volcanoes. They harden to form igneous rocks.
What was Granite before it became a igneous rock?
what was granite before it became igneos rocks?
The factor by which grain size increases with each texture category?
Grain size typically increases by a factor of 2-4 for each texture category. For example, from fine to medium grain size, there is a doubling or quadrupling of grain size. This progression helps geologists classify rocks based on their crystal sizes.
What are rough textured rocks?
Rocks with a large grain size perhaps with angular grain shapes.
What are fine textured rocks?
They are rocks with a small grain size.
Is it true that coarse grain is a term that describes a rocks grain pattern?
yes
Which 2 groups is broken down into smaller groups by grain size?
Sedimentary rocks and igneous rocks can be broken down into smaller groups based on grain size. In sedimentary rocks, grain size categories include clay, silt, sand, and gravel. In igneous rocks, grain size categories include fine-grained, medium-grained, and coarse-grained.
How are rocks with grains classified?
They are eather fine grain or course grain. Granite are course Grain, Basalts are fine grains.
What properties do all rocks have?
Rocks have color, grain, specific density, and relative hardness.
Are all rocks have the same texture and grain size?
no
