What are the types of rocks?
Obsidian sphere
There are different types of rocks, and they are:
• Igneous
• Sedimentary
• Metamorphic

How are Rocks formed?
• Igneous rocks are formed from heated magma either underground or above ground.
• Sedimentary rocks are formed from sediments being collided.
• Metamorphic rocks are made because sedimentary or igneous rocks are under tons and tons of pressure, which fosters heat, builds up, and this causes them to change.

How do I identify rocks?• Igneous rocks are tough, frozen
melts with little texture or layering; mostly black, white and/or gray minerals which may look like granite or like lava.
• Sedimentary rocks are hardened sediment with sandy or claylike layers mostly brown to gray; may have fossils and water or wind marks.
• Metamorphic rocks are tough, with straight or curved layers of light and dark minerals various colors, often glittery with mica.

Where are rocks located?
• Igneous rocks are found near volcanoes
• Sedimentary rocks are found at places that had water at one point of time.
• Metamorphic rocks are found deep underground where there is intense heat and pressure.
