Today we are going to talk about the types of rocks and how they are formed.now who knows what a rock cycle is,and how the three rocks are formed?
I know what a rock cycle is,a rock cycle is the forming and decomposing of a rock,and the three rocks we learned about in class are Igneous,metamorphic,and sedimentary.
Very good Luna now can you describe how those three rocks are formed?
I sure can,a metamorphic rock is formed from heat and pressure,and a sedimentary rocks are formed from weathering,compaction,and cementation,and igneous rocks form when magma cools
True but don't forget that there are to types of igneous rocks intrusive igneous rocks and extrusive igneous rocks.
Oh yeah intrusive igneous rock are formed when magma cools and harden's and extrusive rocks form when lava cools and harden's
