There is a big difference between minerals and rocks. Rocks are groups of different minerals pushed together and combined. The minerals that make up rocks are quartz, sand and etc. The formation of rocks is due to various effects on the Earth. There are THREE types of rocks: Igneous, Sedimentary and Metamorphic. The video below might help you remember them.
Now for the real thing! This next video gives you a deeper understanding of rocks and the rock cycle:D
Questions to ponder...
- What can we look out for when we want to tell if the volcano is about to erupt?
- How is magma made in the Earth's interior?
- If there were no such things as volcanos, causing magma and lava to stay inside the Earth, what would be the affect on Earth and us?
