[Mission 2022] QUIZ – 2022: INSIGHTS STATIC QUIZ, 14 June 2022 – Geography

Solution: a)

The atmosphere consists of different layers with varying density and temperature. Density is highest near the surface of the earth and decreases with increasing altitude. 

Thickness of the troposphere is greatest at the equator because heat is transported to great heights by strong convectional currents.

One important feature of the stratosphere is that it contains the ozone layer. This layer absorbs ultra-violet radiation and shields life on the earth from intense, harmful form of energy.

Solution: c)

In the Mesosphere temperature starts decreasing with the increase in altitude and reaches up to minus 100° C at the height of 80 km.

Ionosphere:

• It contains electrically charged particles known as ions, and hence, it is known as ionosphere.
• Radio waves transmitted from the earth are reflected back to the earth by this layer.

The International Space Station orbits in the thermosphere.

Solution: c)

A tornado may form within a cyclone. A tornado forms due to the effect of low pressure in the eye of a cyclone.

Tornadoes and hurricanes appear to be similar in their general structure. Both are characterized by extremely strong horizontal winds swirling around the center, strong upward motion dominating the circulation with some downward motion in the center. Hurricanes always rotate counter-clockwise in the northern hemisphere (clockwise in the southern), the direction of their rotation being determined by the Earth’s rotation. This is almost always true of tornadoes too, although on rare occasions “anticyclonic” tornadoes spinning in the opposite direction do occur.

The most obvious difference between tornadoes and hurricanes is that they have drastically different scales. They form under different circumstances and have different impacts on the environment. Tornadoes are “small-scale circulations”. Hurricanes, on the other hand, are large-scale circulations.

Solution: b)

Footloose industry is a general term for an industry that can be placed and located at any location without effect from factors of production such as resources, land, labour, and capital.

These industries often have spatially fixed costs, which means that the costs of the products do not change despite where the product is assembled. Diamonds, computer chips, and mobile manufacturing are some examples of footloose industries. These are generally non-polluting industries.

Non-footloose industries generally require raw material availability within a time limit to make products. Sugar industry, jute industry and tea industry are the examples of non-footloose industries.

Solution: b)
