Answers

Surface winds on Earth are primarily caused by differences in Air density due to unequal heating of Earth's surface. The answer is letter A. Surface currents are driven by winds that blow in certain patterns. They are caused by the Earth’s spin and the Coriolis effect. Evaporation adds water to the atmosphere. It is the change from liquid to gas wherein liquid molecules tends to go the gas phase and increases the number of molecules. 

Explanation:

Causes of Different Pressure on the Earth's Exterior. Differences in pressures across the cover of the Earth are fundamentally produced by irregular heating of the surface by the Sun.

Final answer:

Surface winds on Earth are primarily caused by differences in air density due to unequal heating of Earth's surface. The Hadley circulation and the Coriolis effect influence the direction and patterns of these winds.

Explanation:

Surface winds on Earth are primarily caused by differences in air density due to unequal heating of Earth's surface. When the sun's rays hit the equator, the air at this latitude becomes heated and rises, creating an area of low pressure. This causes air from cooler, higher pressure areas to flow towards the equator, resulting in surface winds.

This circulation pattern is known as the Hadley circulation and is responsible for the trade winds, which blow from east to west near the equator. Similarly, the temperature differences between the poles and the equator create the polar easterlies and the prevailing westerlies.

As the Earth rotates on its axis, the Coriolis effect comes into play, causing the wind to be deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This is why trade winds blow from east to west and prevailing westerlies blow from west to east.

What is this equation for?

Answers

That's the equation for the efficiency of any machine or other system that you use to change energy from one form to another. It says that the efficiency of that device is equal to the work or energy that comes out of it divided by the work or energy that you put into it.

Answers

D. ALL OF THE ABOVE.

Promotional claims are given by companies to attract potential buyers with the intent of selling their goods and services.

Consumers must not only rely on what these promotional claims are saying, instead one must do his or her own research to verify if said claims are true, will benefit the consumer and is the only viable or practical solution needed to satisfy the needs of the consumer.
