Subject: New Information About the Rocky Mountains

Greetings, student geologists! You did an excellent job understanding which

processes formed the sediment and magma that ended up making rock formations

in the Great Plains and Rocky Mountains.

We now know the magma that formed the Rocky Mountains cooled underground,

Use this new information to help you figure out more about the claims: How could

the sediment that formed the Great Plains have come from the rock of the Rocky

Mountains? How could the magma that formed the Rocky Mountains have come

from the rock of Great Plains?

What are your initial thoughts about this new information? What additional information do you think

you would need in order to evaluate the claims?
