Question

The pressure and wind systems are actually the impact of Lithosphere and Hydrosphere on ______.
A) Homosphere
B) Heterosphere
C) Atmosphere
D) Troposphere

Answer 1

Hint: Wind is the outcome of horizontal difference in air pressure. Since the sun heats several parts of the Earth differently, this causes pressure differences as the Sun is the driving force for most winds. The pressure and wind systems are actually the impact of Lithosphere and Hydrosphere on a layer of gases.

Complete answer:
Wind is a moving air which is caused due to differences in air pressure in our atmosphere. Air under high pressure is directed towards areas of low pressure. Hence, the greater the difference in pressure, the faster the air flows. If the high pressure area is close to the low pressure area then the pressure difference is very great. Hence, the wind can blow very fast.

The lower layer of the atmosphere is called the homosphere because it has a steady chemical composition and is composed of a changeless mixture of several gases. This option is incorrect.

The main constituents of Earth's thermosphere are nitrogen, oxygen, helium, and hydrogen. This opinion is incorrect.

The pressure and wind systems are actually the impact of Lithosphere and Hydrosphere on the atmosphere. Interactions also arise among the spheres; for example, a change in the atmosphere can cause a change in the hydrosphere and vice versa. This option is correct.

The troposphere is the lowest layer of our atmosphere where humans live.This opinion is incorrect.

Hence the correct answer is option ‘C’.

Note:
a) The Earth's pressure patterns and resulting winds affects the climatic patterns :
-by advecting temperature and moisture.
-causing areas of surface convergence and divergence.
b) Nitrogen constitutes 71 percent, oxygen constitutes 21 percent and argon constitutes 1 percent of the atmosphere.
