Hi Henry. Are you ready to learn about the rock cycle?
Hi Emma. I can't wait! Can we go and see the Colorado River?
Isn't it beautiful here? Look at all the Metamorphic Rocks surrounding the river.
It's nice. Can you believe all these rocks used to be under the earth's surface a long time ago.
Igneous Rocks form when the rocks get below the earth's surface it reaches magma and melts. Then it erupts and cools to become igneous rock.
Wow. The Volcano looks like it's going to blow up.
Emma and Henry meet begin their adventure in Denver, Colorado. The Rocky Mountains have a lot of Sedimentary Rocks. These rocks go through weather and erosion. Then they form from sediments of broken rocks or organic matter that get compacted.
Next, they visit the Colorado River. The Metamorphic rocks form underground when heat and pressure change existing rock. Then the rocks come back to the surface.
Next Emma wants to go fly to Hawaii's Volcano National Park to see what happens to magma when it cools.
