erosion
volcano
earthquake
continental drift
10
The amount of dissolved salts in the ocean is called
thermocline

plankton are free swimming
benthos are alive
benthos are free swimming
plankton float on the surface

water
gravity
glacier
17
An underwater mountain chain that forms on the ocean floor is known as a
mid-ocean ridge
continental shelf
rift zone
continental slope
18
Which feature is proof that the Rockies are relatively younger that the ones in the East?
weathering has not yet hardened the rock
their sedimentary layers are still exposed
they have rounded tops
they have sharp peaks
19
Which natural force creates surface ocean currents?
