Magma

400

What is needed for igneous rock to turn into metamorphic rock?

High heat and pressure under ground

400

400

What is needed to change scientific knowledge that was previously proven correct?

New evidence

400

400

What type of rock would you find at location A?

Metamorphic Rock

500

What type of rock would you find at location B?

Sedimentary Rock

500

500

How do scientists know that the mid-Atlantic ridge is spreading apart?

Because the older rocks are found farther away from the middle.

500

What is occuring at the middle between the two currents?

The currents are running into each other and will cause a plate to rise up.

500

Why would the theory of plate tectonics be reviewed and updated?

Because new evidence was uncovered and it needed to be updated.
