Which of these describes the process of how humans depend on the ocean through desalination?

• Transportation and recreation - transporting goods by boat and ship and depending on the ocean for recreational activities

• Food and products - humans using ocean organisms for food and other products

• Air - organisms in the oceans produce oxygen

• Drinking water - removing salt from ocean water to make fresh drinking water

Mesosaurus fossils have been found in Africa and South America. What does the distribution of Mesosaurus fossils suggest about the position of these continents 280 million years ago?

• B. The continents were farther apart than they are today.

• C. The continents were in the same position as they are today.

• D. The continents were connected as part of a larger landmass.

A model of plate movement is shown below. Which of these best describes the type of plate boundary shown and the result of this movement?

• The boundary is a transform boundary showing ocean basin formation.

• The boundary is a divergent boundary showing an earthquake.

• The boundary is a transform boundary showing a mid-ocean ridge formation.

• The boundary is a convergent boundary showing mountain formation.

Which of the following best describes a watershed?

• A body of water where groundwater collects before entering a stream

• A small river that feeds into a larger river system

• The area of land where all precipitation drains into a single body of water

• A wetland area where surface water evaporates into the atmosphere

How does this type of boundary result in the formation of new ocean basins?

• By sliding plates horizontally past each other

• By creating new oceanic crust as plates move apart

• By folding and uplifting existing crust to form mountains

• By pushing old oceanic crust down into the mantle
