There are 3 main types of rocks:
Igneous Rocks
Forms when molten rock cools.
2 types of molten rock: magma, and lava.
- Intrusion: Forms when magma cools. Intrusion rocks take longer to form because magma takes longer to cool. Magma is under the Earth's surface, and it is very hot there. Imagine how long it would take for magma to cool down somewhere a thousand degrees!
- Extrusion: Forms when lava cools. Extrusion don't take as long to form, because lava cools much faster than magma does. Lava is at the surface, and the surface is WAY cooler than underground.
Sedimentary Rock
Forms when rocks/minerals/remains of plants or animals settle and accumulate.
Forms in layers.
3 types of sedimentary rock:
- Clastic - forms from accumulation of rock fragments and minerals.
- Biologic - forms from plant or animal remains.
- Chemical - forms when minerals precipitate out of a solution.
Metamorphic
Preexisting rocks that have changed form by heat and pressure.
If you are looking for specific types, here are some brief examples:
Igneous Rocks
Basalt
Pegmatite
Granite
Tuff
Sedimentary Rocks
Limestone
Coal
Shale
Siltstone
Metamorphic Rocks
Slate
Gneiss
Schist
Marble

Why do rocks have different colors?
Rocks have different colors due to the presence of various minerals and chemical compounds in their composition. The minerals present can reflect different wavelengths of light, resulting in different colors. Factors such as oxidation, weathering, and environmental conditions can also influence the color of rocks.
What are rocks with stripes called?
Rocks with stripes are known as banded rocks or striped rocks. These stripes are often caused by the layering of different minerals or the presence of alternating bands of different mineral compositions within the rock.
Do all rocks weather the same way?
Erosion rates depend on the composition of the rocks and how they are attacked by the environment.Different kinds of rocks have different composition and will erode at different rates.Rocks in different places will be affected differently by wind, water, ice, rain, pollutants, etc. and so they will erode at different rates.
What are the parent rocks of a metamorphic rock?
Parent rocks of metamorphic rocks can include igneous, sedimentary, or pre-existing metamorphic rocks. These rocks undergo changes in mineralogy and texture due to heat, pressure, and chemical processes without melting, resulting in the formation of metamorphic rocks. Different parent rocks can give rise to different types of metamorphic rocks.
Are rocks made out of different kind of minerals?
Yes, rocks are made up of different combinations of minerals. Minerals are naturally occurring inorganic substances with a specific chemical composition and crystalline structure. When minerals come together and form a solid mass, they create rocks with a variety of physical and chemical properties.
How the rocks are different from rocks associated with plate-boundary orogeny?
How are what rocks different?
what describes the compostition of rocks?
Rocks are made up of minerals. Different rocks consist of different minerals in different proportions.
How are the three different types of rocks different?
Each of the rocks form in a different way.
Why do rocks have different colors?
Rocks have different colors due to the presence of various minerals and chemical compounds in their composition. The minerals present can reflect different wavelengths of light, resulting in different colors. Factors such as oxidation, weathering, and environmental conditions can also influence the color of rocks.
How are the three major rocks are different?
Each of the rocks form in a different way.
Why are rocks not the same?
Because different rocks are formed by different processes and made up of different mineral assemblages.
What is the formulae for rocks?
There are thousands of different types of rocks...What type of rocks in particular?
How many rocks are ther?
There are thousands of different types of rocks.
What processes form different kinds of rocks?
The pooper scale is used to form different kinds of rocks.
Why do some rocks have different minerals?
the reason is because rocks can have different depositional environments and diagenesis history.
What are the rocks made of?
If you're talking about rocks in general then Rocks are made of combinations of different minerals.
What are rocks with stripes called?
Rocks with stripes are known as banded rocks or striped rocks. These stripes are often caused by the layering of different minerals or the presence of alternating bands of different mineral compositions within the rock.
