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.
What 2 groups of rocks are formed from all 3 Sedimentary Igneous metamorphic?
clastics,organic,and chemicals rock.
Name the three types of rocks?
Igneous, sedimentary, and metamorphic rocks are the three main types of rocks. Igneous rocks are formed from the cooling of molten rock, sedimentary rocks from the accumulation of sediment, and metamorphic rocks from the transformation of existing rocks under heat and pressure.
What 2 rocks are formed from all 3 kinds of rocks?
I would say Igneous and Metamorphic rocks.
Name the three families of igneous rocks?
This is a very simplistic answer. But, it should reveal the basic processes involved in rock formation.1. Sedimentary, like coal and limestone. They are made from particles of substances that settle and coalesce into a layer that becomes rock.2. Igneous, like granite and basalt. These rocks were formed by heat. Think of lava.3. Metamorphic: Marble and slate. These are rocks that were in another form and got changed by pressure into their present form.
What are 2 fine-grained igneous rocks?
Granite and Bassalt
What are facts about igneous?
.The oldest rock known today is the Igneous rock. .Igneous rock can be any colour..The word "Igneous" is a Greek word that means fire. Igneous rocks are formed by the cooling of molten rock, lava or magma. When magma solidifies in the earth they are intrusive, when lava cools outside the earth it is extrusive.
What are 2 types of organic rocks?
Metamorphic and Igneous are two types.
Which is NOT one of the ways in which an igneous rock is emplaced into pre-existing rocks?
2*2
What kind of rock does magma form when it hardens?
If the magma cools on the surface of the crust, it is called extrusive igneous rock, such as pumice, basalt or rhyolite. If the magma cools inside the crust, it is called intrusive igneous rock, such as granite.
Igneous rocks are formed when magma does what?
The Igneous rock formed when magma cools are; 1. Extrusive (Volcanic) Igneous Rock; which are igneous rocks formed when magma cools outside the earths crust. The texture of of extrusive igneous rock is fine grained. 2. Intrusive (Plutonic) Igneous Rock; these are igneous rocks formed by gradual cooling of magma within the earths crust. The texture is coarse grained.
