QUIZ – 2020: INSIGHTS STATIC , 2 August 2021 – Geography – INSIGHTSIAS

Solution: c)

Waves are actually the energy, not the water as such, which moves across the ocean surface. Water particles only travel in a small circle as a wave passes. Wind provides energy to the waves. Wind causes waves to travel in the ocean and the energy is released on shorelines. The motion of the surface water seldom affects the stagnant deep bottom water of the oceans. As a wave approaches the beach, it slows down. This is due to the friction occurring between the dynamic water and the sea floor. And, when the depth of water is less than half the wavelength of the wave, the wave breaks. The largest waves are found in the open oceans. Waves continue to grow larger as they move and absorb energy from the wind.

Solution: b)

Solution: b)

The ionosphere is located between 80 and 400 km above the mesopause. 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. Temperature here starts increasing with height.

Solution: d)

Africa has the highest population growth rate.

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. 

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.

Location of Cotton textiles, Cement industry and, Iron and Steel industries largely depend upon location of the raw materials. Thus, cannot be considered under the category of the Footloose industries.
