Which of the following models MOST accurately represents the air circulation patterns likely to develop on a hot summer afternoon in a coastal area?

Answers

Answer:

A

Explanation:

The model that most accurately represents the air circulation patterns likely to develop afternoon in a coastal area is the model a. The correct option is a.

The atmosphere is fixed to the earth by gravity and rotates with the earth, there would be no circulation if some force did not upset the atmosphere's equilibrium.  The heating of the earth's surface by the sun is the force responsible for creating the circulation that does exist.

Because of the curvature of the earth, the most direct rays of the sun strike the earth in the vicinity of the equator resulting in the greatest concentration of heat, the largest possible amount of radiation, and the maximum heating of the atmosphere in this area of the earth.  At the same time, the sun's rays strike the earth at the poles at a very oblique angle, resulting in a much lower concentration of heat and much less radiation so that there is, in fact, very little heating of the atmosphere over the poles and consequently very cold temperatures.

Cold air, being more dense, sinks and hot air, being less dense, rises.  Consequently, the rising warm air at the equator becomes even less dense as it rises and its pressure decreases.  An area of low pressure, therefore, exists over the equator.

How is a warm front different from a cold front?
A.Warm fronts cause snow flurries in the winter, while cold fronts cause several days of rainy weather.

B.Warm fronts cause rapid changes in weather, while cold fronts cause several days of cloudy weather.

C.Warm fronts cause several days of cloudy weather, while cold fronts cause heavy snow in the winter.

D.Warm fronts cause thunderstorms in the summer, while cold fronts cause rain when the air is humid.

Answers

Answer:

The answer is c i have been in a cold front before

Explanation:

Any front defines the line separating two different air masses; in the case of a warm front, it defines the line dividing the cold air from the warm air that is replacing it.

A cold front, in this instance, delineates the transition zone between warm air and the colder air that is replacing the warm air.

Option C is correct:  Warm fronts cause several days of cloudy weather, while cold fronts cause heavy snow in the winter.

Explain the difference between  cold air warm and?

Because cold air is heavier than warm air, there is a condition known as high pressure. Low pressure is brought on by warmer, lighter air.

Air molecules are more closely spaced in an area of higher pressure than they are in one of lower pressure. A low pressure area is created when air that has been warmed applies less pressure to the ground.
