atmosphere & climatology section 1 MCQ Questions & Answers Detailed Explanation

Answer: (d)

The troposphere is the lowest layer of Earth’s atmosphere. It starts at Earth’s surface and goes up to a height of 7 to 20 km above sea level.

Most of the mass (about 75-80%) of the atmosphere is in the troposphere. Almost all weather occurs within this layer.

Answer: (a)

By analyzing climogram, we can get relevant information about a climate of a place. It shows wind direction and frequency of wind.

Answer: (a)

Answer: (a)

Horse Latitudes are the subtropical belts of variable winds and columns that is between the latitudes 25° and 35° south and north. They coincide with sub-tropical high-pressure belts.

Answer: (c)

Mistral the local wind is different from the others.

The mistral is a strong, cold and usually dry regional wind in France, coming from the north or northwest, which accelerates when it passes through the valleys of the Rhone and the Durance Rivers to the coast of the Mediterranean around the Camargue region.

Answer: (d)

1. In the troposphere temperature falls with the height. The troposphere, the lowest layer of Earth’s atmosphere, is heated from below. Higher up in the troposphere, where less heat from the surface warms the air, the temperature drops.
2. The ionosphere reflects radio waves back to the earth.
3. The ozone layer or ozone shield is a region of Earth’s stratosphere that absorbs most of the Sun’s ultraviolet (UV) radiation. It contains high concentrations of ozone (O3) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere.
4. The tropopause is the boundary between the troposphere (which is based at the earth’s surface and has a temperature that decreases with height) and the stratosphere (which is a stable region of very low levels of vertical mixing above the troposphere).
