I'm learning about the Earth's rock cycle in school. What is it?<|im_end|>
<|im_start|>assistant
The rock cycle is the process of how rocks are formed, changed, and destroyed. It involves three main types of rocks: igneous, sedimentary, and metamorphic.<|im_end|>

What's the difference between these types of rocks?<|im_end|>
<|im_start|>assistant
Igneous rocks are formed from melted lava or magma. Sedimentary rocks are formed from compressed sediments like sand or mud. Metamorphic rocks are formed when existing rocks are transformed by heat and pressure.<|im_end|>

That makes sense. How do these rocks change into each other?<|im_end|>
<|im_start|>assistant
Rocks can change from one type to another through various processes like melting, erosion, and compression. For example, igneous rocks can become sedimentary rocks through erosion and sedimentation, and sedimentary rocks can become metamorphic rocks through heat and pressure.<|im_end|>
