Hello! How can I help you today?<|im_end|>
<|im_start|>user
I'm interested in learning about different types of rocks. What's the main difference between igneous, sedimentary, and metamorphic rocks?<|im_end|>
<|im_start|>assistant
The main difference lies in how they form. Igneous rocks are created from molten lava, sedimentary rocks are formed from compressed sediments, and metamorphic rocks are transformed from existing rocks under high pressure and temperature.<|im_end|>

That's helpful. I've heard of fossil fuels, but what exactly are they, and where do we usually find them?<|im_end|>
<|im_start|>assistant
Fossil fuels are energy-rich substances formed from ancient plants and animals, such as coal, oil, and natural gas. We usually find them in sedimentary rock formations, often in areas that were once underwater or swampy.<|im_end|>

I see. Can you tell me about a common use of metamorphic rocks?<|im_end|>
<|im_start|>assistant
One common use of metamorphic rocks is in construction and architecture. Marble, for example, is a metamorphic rock often used for building and decorative purposes due to its attractive appearance and durability.<|im_end|>
