Question

Emmon makes four conclusions from a set a data that shows the Sun's affect on the movement of water. Which of the following conclusions is NOT an conclusion Emmon could have made from the data collected?

The Sun is not a major source of energy for water movement.


Warm water rises above the cooler water.


Ocean currents are only caused by density differences.


Water is not warmed by the Sun.

Answer 1

Ocean currents are only caused by density differences.

Reason: The data showing the Sun's effect can support that warming (and resulting density differences) causes water movement, but it cannot support the exclusive claim that density differences are the only cause — currents are also driven by wind, tides, and Earth's rotation (Coriolis effect).
