1. Movement of air is caused by temperature or pressure differences and is eperienced as wind. Where there are differences of pressure between two places, a pressure gradient exists, across which air moves: from the high-pressure region to the low-pressure region. This movement of air however, does not follow the quickest straight-line path. In fact, the air moving from high to low pressure follows a spiralling route, outwards from high pressure and inwards towards low pressure. This is due to the rotation of the Earth beneath the moving air, which causes an apparent deflection of the wind to the right in the Northern Hemisphere, and to the left in the Southern Hemisphere. The deflection of air is caused by the Coriolis force. Consequently, air blows anticlockwise around a low-pressure centre (depression) and clockwise around a high-pressure centre (anticyclone) in the Northern Hemisphere. This situation is reversed in the Southern Hemisphere.

2. A cold front is defined as the transition zone where a cold air mass is replacing a warmer air mass. Cold fronts generally move from northwest to southeast. The air behind a cold front is noticeably colder and drier than the air ahead of it. When a cold front passes through, temperatures can drop more than 15 degrees within the first hour. There is typically a noticeable temperature change from one side of a cold front to the other. In the map of surface temperatures below, the station east of the front reported a temperature of 55 degrees Fahrenheit while a short distance behind the front, the temperature decreased to 38 degrees. An abrupt temperature change over a short distance is a good indicator that a front is located somewhere in between.

4.Wind is moving air. The air is moved by the heat from the sun. The sun’s rays touch the earth, the earth absorbs the heat from the sun, and then the earth warms up the air that is very close to it. That warm air rises up into the sky. After the warm air rises, fresh cool air sinks down close to the earth and gets warmed up, and then it rises up into the sky. This makes wind. We couldn’t have wind without the sun warming the earth because solar energy creates the wind cycle .

5.Thunderstorms are most likely to occur in the spring and summer months and during the afternoon and evening hours but they can occur year-round and at all hours of the day or night. Along the Gulf Coast and across the southeastern and western states, most thunderstorms occur during the afternoon. Thunderstorms often occur in the late afternoon and at night in the Plains states. Thunder and lightning can sometimes even come with snowstorm! During the blizzard of March 1993, lightning resulted in power outages near Washington, D.C.

6. Sorry not sure.

4 out 6 isn't bad.

3. Because of uneven-heating of the Earth and the fact that warm air rises and cool air falls, there arise circulations that (on a non-rotating planet) would lead to an equator-to-pole flow in the upper atmosphere and a pole-to-equator flow at lower levels. Because of the Earth's rotation, this simple situation is vastly modified in the real atmosphere.
4. No. Wind is caused by the uneven-heating of the Earth by the Sun. When hot air rises and the cooler air takes its place, the result is wind.
