The correct response is: the amount of heat in each area.

The pressure difference between the equator and the poles is primarily caused by the uneven heating of the Earth's surface. The equator receives more direct sunlight and is generally warmer, leading to lower pressure, while the poles receive less direct sunlight and are cooler, resulting in higher pressure. This difference in temperature creates a pressure gradient that drives atmospheric circulation.

Why is the equator region the hottest part of Earth’s surface?(1 point)
Responses

The equator region is closest to the sun.
The equator region is closest to the sun.

The rays of the sun hit the equator region at an angle.
The rays of the sun hit the equator region at an angle.

The sun shines directly on the equator region.
The sun shines directly on the equator region.

The equator region has the widest diameter.

The correct response is: The sun shines directly on the equator region.

At the equator, sunlight hits the Earth's surface more directly compared to the poles, which receive sunlight at a more oblique angle. This direct exposure results in higher temperatures in the equatorial region.

What is the process through which clouds are formed?(1 point)

transpiration

condensation
condensation

evaporation

The correct response is: condensation.

Clouds are formed when water vapor in the air cools down and condenses into tiny water droplets or ice crystals. This process takes place when air rises and cools, leading to the formation of clouds.

What happens to the air and wind that causes high-pressure systems?(1 point)
Responses

Cool air warms as it rises and the wind blows inward.
Cool air warms as it rises and the wind blows inward.

Warm air cools as it sinks and the wind blows outward.
Warm air cools as it sinks and the wind blows outward.

Cool air warms as it sinks and the wind blows outward.
Cool air warms as it sinks and the wind blows outward.

Warm air cools as it rises and the wind blows inward.

The correct response is: Warm air cools as it sinks and the wind blows outward.

In high-pressure systems, air is typically cooled as it sinks toward the surface. As the cool air descends, it leads to higher pressure at the surface, and the sinking air produces outward blowing winds.

What drives the circulation of air in the atmosphere?(1 point)
Responses

condensation
condensation

evaporation

conduction
conduction

convection

The correct response is: convection.

Convection drives the circulation of air in the atmosphere. It refers to the process where warm air rises and cooler air sinks, creating circulation patterns that help distribute heat and moisture around the planet.
