Why are oceans salty?

As a result of rivers carrying salts and minerals from land to the oceans (correct)

From underground aquifers releasing salty water into the oceans

Because the sun evaporates saltwater leaving salt behind in the oceans

Due to excessive rainfall dissolving minerals from soil and rocks into the oceans

What is the primary source of energy for the water cycle?

Geothermal heat

The sun (correct)

Wind

Ocean currents

How can a water supply be extended?

By building more dams

By recycling or using less water (correct)

By increasing desalination plants

By redirecting rivers to areas in need
