Atmosphere MCQ Question and Answer | Geography MCQ Question

Agents of fog formation do not include Diurnal temperatures of short ranges. Diurnal temperature range (DTR) is defined as the difference between daily maximum and minimum temperature, which describes the within-day temperature variability and reflects weather stability.

Pressure gradient force is most powerful in determining movement of wind including its velocity. Wind is the movement of air across the Earth's surface and is produced by differences in air pressure between one place to another.

Atmospheric humidity is measured by psychrometer. A psychrometer measures humidity by taking both a wet-bulb and a dry-bulb temperature reading.

The thermosphere is a layer of Earth's atmosphere. The thermosphere is directly above the mesosphere and below the exosphere. It extends from about 90 km (56 miles) to between 500 and 1,000 km (311 to 621 miles) above our planet. Based on the vertical temperature profile in the atmosphere, the thermosphere is the highest layer, located above the mesosphere.

The trade winds of the Southern Hemisphere need to cross the equator in order to reach the ITCZ. Thus, the trade winds of the Southern Hemisphere cross the equator but are deflected towards right under the Coriolis Effect.

The amount of insolation received on the earth’s surface is far less than that is radiated from the sun because of the small size of the earth and its distance from the sun. The amount of insolation received on the earth’s surface is not uniform everywhere. It varies according to the place and time. When the tropical regions receive maximum annual insolation, it gradually decreases towards the poles. Insolation is more in summers and less in winters.

The inner most layer of the earth is called the “Core or Barysphere”. It is otherwise known as NIFE, because of the presence of Nickel and Ferrous (iron).

Although monsoons are often erroneously identified as rainstorms, they are actually a seasonal wind. A monsoon is a wind in low-latitude climates that seasonally changes direction between winter and summer.

Evening sun is not a shot as the mid-day sun because in the evening, radiations travel larger distance through atmosphere. Light from the sun, near the horizon, passes through thicker layers of air and covets a large distance in the earth's atmosphere before reaching our eyes. However, light from the sun overhead would travel realitively shorter distance.

As air temperature increases, air can hold more water molecules, and its relative humidity decreases.
