Answer 1

1. The three main types, or classes, of rock are sedimentary, metamorphic, and igneous.

2. A rock is a solid made up of a bunch of different minerals

Rock cycle⤵️⤵️

1. Melted rock or magma is sent to the earth's surface by a volcano. It cools and forms an igneous rock.

2. Next the weather, or a river, and other events will slowly break up this rock into small pieces of sediment.

3. As sediment builds up and hardens over years, a sedimentary rock is formed.

4. Slowly this sediment rock will get covered with other rocks and end up deep in the Earth's crust.

5. When the pressure and heat get high enough, the sedimentary rock will metamorphose into a metamorphic rock and the cycle will start over again.

3. organic mineral is a mineral that contains carbon. However, some simple compounds involving carbon are classified as inorganic. Some organic mineralsare composed of hydrocarbons, while others are salts of organicacids, as well as some miscellaneous compounds like यूरिया. But inorganic minerals are not made of carbon.
