Atmosphere MCQ Question and Answer | Geography MCQ Question

The upper boundary of the layer, known as the tropopause, ranges in height from 5 miles (8 km) near the poles up to 11 miles (18 km) above the equator.

Nimbostratus clouds cover the sky in a dark gray layer. They can extend from the low and middle layers of the atmosphere and are thick enough to blot out the sun. Nimbostratus are the quintessential rain cloud.

Hail is produced by the rapid ascent of moist air. The hard pellets of ice having diameter of 5 mm or that fall from Cumulonimbus clouds, and are generally associated with thunderstorms is known as hail. They are formed by the rapid ascent of moist air; the water drops freeze, and the size of the pellets increases as more water Vapour freezes on to their surface.

The correct sequence of different layers of the atmosphere from the surface of the Earth upwards is Troposphere, Stratosphere, Mesosphere and Thermosphere. The troposphere is the layer that we live in. The troposphere starts at ground level and extends about 12 km upwards. From about 12 km to 50 km upwards is the stratosphere. In this layer, the jet stream blows strong winds eastward. The mesosphere is the coldest region of Earth’s atmosphere. It’s somewhere close to -100° Celsius. Themosphere is the thickest layer in the atmosphere is the thermosphere starting at about 80 km going upwards.

A cumulus cloud that exhibits significant vertical development (but is not yet a thunderstorm) is called cumulus congestus or towering cumulus. If enough atmospheric instability, moisture, and lift are present, then strong updrafts can develop in the cumulus cloud leading to a mature, deep cumulonimbus cloud, i.e., a thunderstorm producing heavy rain. In addition, cloud electrification occurs within cumulonimbus clouds due to many collisions between charged water droplet, graupel (ice-water mix), and ice crystal particles, resulting in lightning and thunder.

The heat source for our planet is the sun. Energy from the sun is transferred through space and through the earth's atmosphere to the earth's surface. Since this energy warms the earth's surface and atmosphere, some of it is or becomes heat energy.

Atmosphere contains particles and gases which do not escape to outer space because they are bounded by the force known gravity. Earth's gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body. That's what gives you weight. And if you were on a planet with less mass than Earth, you would weigh less than you do here.

Some large lakes in temperate latitudes have a moderating influence upon the climate of adjacent land surfaces. Such an influence may develop when prevailing out-blowing winds cross the lake in winter.

The clouds extending from one side of horizon to other as 3 dark grey sheet having uniform base are called Stratus clouds. They are composed of thin layers of clouds covering a large area of the sky. This is simply mist or fog when it forms close to the ground.

The following characterises the Foehn are that It is warm, It is common in the valleys of the northern Alps and It blows in winter.
