How did the different layers of rock in the Grand Canyon come about?
Over time, layers of rock are stacked on top of each other.
What type of rock at the Grand Canyon can be easily identified by using Hydrochloric Acid?

How are volcanoes and mountains formed?
When the tectonic plates fold under each other.
What is chemical weathering?
When chemicals in rocks change due to chemical reactions
