Based on the direction of the Cocos Plate, what type of plate boundary likely exists between the Cocos Plate and the Caribbean Plate? (Hint: Step 1. Analyze the likely relative motions of the Caribbean Plate and the Cocos Plate. Step 2. Relate the relative motions of plates to the type of plate boundary.)

What is the best explanation for why the oldest rocks found on Earth are not as old as meteorites?
Meteorites do not contain any elements found on Earth.
Earth processes, such as volcanic eruptions, make new rocks.
Meteorites did not form in our solar system.
Earth processes, such as mountain building, have destroyed older rocks.
