• just over 3,000 cubic miles

• nearly 43,000 cubic miles

• about 46,000 cubic miles

• close to 6,000,000 cubic miles

What causes convection currents to form in the oceans?

• surface winds

• the Coriolis effect

• continental deflection

• differences in water density

Tai grows plants in a container called a terrarium, as shown below. He keeps the terrarium on a sunny windowsill. The terrarium is closed, so Tai cannot add water to the plants. However, the plants have enough water to grow. Which of these statements best explains why the plants always have enough water?

• The air cannot hold all of the water vapor.

• Water is unable to evaporate from the soil.

• The plants take up water and store it in their stems and leaves.

• Energy from the sun cycles water through the soil, the plants, and the air.

Why is water considered the universal solvent?

• Because all water molecules have a negative charge, so they repel each other.

• Because water will not dissolve many substances.

• Because water can dissolve many substances.

• Because water molecules will not stick to any other water molecules.

As water changes state, the water either absorbs or releases energy. Which of these answers is a process that releases energy?

• ice subliming

• snow melting

• lake water freezing

• ocean water evaporating

Which of the following best describes the movement of heat energy in the global ocean?

• Heat energy is transported to the equator from the continents.

• Heat energy in deep currents is transported to the ocean’s surface.

• Heat energy in warm surface currents is transported to areas near Earth’s poles.

• Heat energy is transported from areas of lower temperature to areas of higher temperature.

What role does heat play in the formation of convection currents?

• When water loses heat, it becomes denser and sinks.

• When water gains heat, it becomes denser and sinks.

• When water loses heat to cooler water, the cooler water becomes denser and sinks.

• When water gains heat, it dissolves more solids and gases, becomes denser, and sinks.

Which of the following correctly explains something that occurred in the time between these two images?

• The ice cubes expanded in volume as they melted into liquid water.

• As water vapor condensed on the glass, it absorbed energy.

• The water droplets outside the glass absorbed energy as they evaporated.

• Some liquid water inside the glass sublimated into water vapor in the air.
