The diagram shows that water is constantly moving throughout Earth with the help of deep ocean currents. Choose the correct order of steps.

• Cool dense ocean water is carried by deep currents, warm water from surface currents sinks to the ocean floor, and less dense water in deep ocean currents rises to enter surface currents

• Cool dense ocean water is carried by deep currents, less dense water in deep ocean currents rises to enter surface currents, and warm water from surface currents sinks to ocean floor

• Warm water from surface currents sinks to the ocean floor, cool dense ocean water is carried by deep currents, and less dense water in deep ocean currents rises to enter surface currents

• Less dense water in deep ocean currents rises to enter surface currents, warm water from surface currents sinks to the ocean floor, and cool dense ocean water is carried by deep currents.

What us the relationship between sunlight and ocean currents?

• The sun evenly heats the ocean's surface. This heat causes the water to move.

• The sun causes uneven heating. The changes in temperature makes the cold water sink and warm water rise, which moves water.

• The sunlight and ocean currents are dating

• The ocean current movements, causes heat which then returns into the sun.

How does this model explain how unequal heating of sun affects global currents?

• The heating of the sun does not affect global currents.

• The core of the earth makes the water around the equator warm. The warm water then stays in the warm regions, leaving cold water to be in cold areas.

• The sun heating makes the currents move at random.

• Sunlight makes the water around the equator very warm. The warm water moves to colder areas, and the cold water moves to warmer areas.

How do currents help scientists understand and predict the weather throughout the world?

• Currents move to places with warm weather.

• Currents indicate which places have high levels of precipitation.

• Currents can help predict which regions experience warming and cooling.

• All of these answers applies.
