Which geologic structure will MOST likely take the longest time to form?

• A fault

• A sinkhole

• A river meander

• A mountain range

The Mariana Trench is the deepest ocean trench on Earth. This trench occurs at a plate boundary where

• one plate is sliding past another

• one plate is being forced beneath another

• two plates are colliding into each other

• two plates are pulling apart from each other
