Hello! I am magma and I want to make friends with 3 interesting guys, there are different kinks of rocks, but I am not a rock. I wonder that they won't want to be friend with me.

The first one is Igneous rock. We can also call him --- "magmatic rock".

Hello everyone! I am from deep seafloor——the oceanic crust. When the molten rock cools and solidifies it become me. I am a strong and brave person, look at my hard body.

Let me introduce a friend of mine——Sedimentary Rock. He also from ocean.

Hi, I am Sedimentary Rock. When particles settle out of water or air, or by precipitation of minerals from water, I am formed. I am a friendly person, I hope you can like me.

Our last friend is Metamorphic Rock.  And he live in deep in Earth.

Hi! I am Metamorphic Rock. When existing rocks are changed by heat, pressure, or reactive fluids, such as hot, mineral-laden water, I formed. I am a reserved and gentle person.

Hi, I'm Magma. I've always wanted to be friends with you, but I'm not a rock. Would you like to be my friend?

Of course, we want to be friends with you, because of you we are formed. Our relationship is indivisible.

Really? We've been good friends since then.
