1. When we look at Planet Earth, and we look at the types of rocks that exist on the planet, which one do you believe is the most important type (Igneous, Metamorphic, or
Sedimentary) within the rock cycle and why. Please explain where you find that type
and please give at least 3 examples of that type of rock (For example, if you say
Metamorphic, then you would need to explain 3 types of metamorphic rocks).

Can someone help me with this pls
