Accepted Answer

Kinetic wind energy forms waves on the surface of the water belongs to energy transfer column and Thermal energy in the air becomes kinetic energy of wind belongs to energy transformation column

Answer

Kinetic wind energy forms waves on the surface of the water belongs to energy transformation and Thermal energy in the air becomes kinetic energy of wind belongs to energy transfer

Answer

None of these fit in either column

Answer

Both fit for both columns

Question 11

Choose the statements (more than one) that accurately describes the processes shown in these figures.

Accepted Answer

In both figures convection is occurring

Accepted Answer

In figure 1 the warm water is coming in from the equator

Accepted Answer

In both figures the movement of water is driven by heat energy

Answer

In figure 2 no current is created because there is not enough room for the cycle to continue

Answer

In both figures water is heated from the deepest part of the water

Question 12

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

Accepted Answer

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

Answer

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

Answer

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

Answer

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.

Question 13

Choose three processes in the water cycle that are driven by the force of gravity.

Accepted Answer

precipitation

Accepted Answer

run off

Accepted Answer

infiltration

Answer

condensation

Answer

evaporation

Question 14

How is the water cycle driven by heat from the sun?

Accepted Answer

The sun heats water which causes evaporation.

Answer

The sun creates gravity which causes run off.

Answer

The heat condenses water into clouds.

Answer

The sun makes the clouds rain.

Question 15

What us the relationship between sunlight and ocean currents?

Accepted Answer

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

Answer

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

Answer

The sunlight and ocean currents are dating

Answer

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

Question 16

How do ocean currents affect climate?

Accepted Answer

Coastal areas near cold currents tend to be cold, and coastal areas near warm currents tend to be warm.

Answer

Ocean currents have no affect on climate.

Answer

Coastal areas near warm currents tend to be cold, and coastal areas near cold currents tend to be warm.

Answer

Ocean currents tend to gravitate near warm climate areas.

Question 17

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

Accepted Answer

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

Answer

The heating of the sun does not affect global currents.

Answer

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.

Answer

The sun heating makes the currents move at random.

Question 18

Why do these currents affect weather? Select all answers that apply.

Accepted Answer

Currents help mix water.

Accepted Answer

Mixing cold and warm water helps temper climates.

Accepted Answer

Warm currents warm the air and cold currents cool the air. This creates wind.

Answer

The currents make it more likely for rain to occur.
