Atmosphere MCQ Question and Answer | Geography MCQ Question

The layer of the atmosphere which provides ideal conditions for flying on et aeroplanes is Stratosphere. Because the air temperature in the stratosphere slowly increases with altitude, it does not cause convection and has a stabilizing effect on atmospheric conditions in the region.

The clouds which we find in the skies of the desert regions do not precipitate because these clouds are comparatively more dry and have a much less amount of water droplets in it ,than the normal precipitation clouds.

Local wind mistral is not characteristically hot and dry. Mistral A cold, dry wind blowing from the north over the northwest coast of the Mediterranean Sea, particularly over the Gulf of Lions.

Calm conditions return when the eye of the cyclone arrives is not associated with the tropical cyclones. It is actually the calmest section of any hurricane. The coriolis force deflects the wind slightly away from the center, causing the wind to rotate around the center of the hurricane (the eye wall), leaving the exact center (the eye) calm.

For decades, scientists believed that the atmosphere of early Earth was highly reduced, meaning that oxygen was greatly limited. By 2.7 billion years ago, a new kind of life had established itself: photosynthetic microbes called cyanobacteria, which were capable of using the Sun's energy to convert carbon dioxide and water into food with oxygen gas as a waste product.

Winds and air currents differ in the aspect that Winds are horizontal movements of air while air currents are the vertical movements of air. Air currents are concentrated areas of winds. All winds result from horizontal differences in air pressure.

Lapse rate is related to the decrease of Temperature at 1°F for an ascent of 330 feet. The lapse rate is the rate at which an atmospheric variable, normally temperature in Earth's atmosphere, changes with altitude.

The most abundant element in the Earth's atmqsphere is Nitrogen. Nitrogen makes around 78.084% of total elements of earth.

Temperature inversions are a result of other weather conditions in an area. They occur most often when a warm, less dense air mass moves over a dense, cold air mass.

Magnetopause is a boundary line between Earth's magnetic field and solar wind. Solar winds forms the part of outer space whereas Earth's atmosphere exists up to magnetic field of Earth.
