Answer:
accurate direction, but has distorted sizes and distance
Answer:
The drag from wind holds the responsibility for driving ocean waves in addition to the surface tension.
Explanation:
The ocean currents at the first 100 m of its surface is moved by the wind drag. Whereas, the ocean currents flowing below the thousand meters of its surface are driven by water's density gradient, which is governed by thermohaline circulation, 'thermo' means temperature and 'haline' means salinity. The centrifugal force has no role to do in driving the ocean current in its surface and earth's rotation causes the Coriolis effect which is an example of hurricane winds.
Answer:
Atmosphere is the envelope of gas which surrounds any celestial body.
Explanation:
The importance of atmosphere of the earth are:-
⇒The presence of the atmosphere plays a significant role in the water cycle. It facilitates the formation of clouds which remains suspended until they are heavy enough to pour down on the earth as rain,hail or snow.
⇒Protects the life forms of the earth from the harmful UV rays of the sun.The presence of the ozone layer does this by reflecting the UV rays of the sun.
⇒ It keeps the temperature of the earth constant so that it is suitable to support life.
⇒It protects the earth from smaller meteors.
⇒ Contains N2O2 and other gases which are necessary to support the life form on the earth.
⇒Facilitates combustion and without the atmosphere combustion is not possible.
