The curved paths of global winds and surface currents are caused bya. the revolution of the Earth.
c. warm air near the equator.
b. the Coriolis effect.
d. continental deflection.

Answers

Answer:

The correct answer is option B, The coriolis effect  

Explanation:

The coriolis effect  describe the pattern followed by an object travelling around the earth. This effect is guided by the rotation of earth. Large air currents appear to bend in the right direction in northern hemisphere while the coriolis effect produces reverse condition in the southern hemisphere where air currents bend to the left  

The impact of the Coriolis effect is dependent on velocity of Earth and the velocity of the object and also on the  fluid being deflected by the Coriolis effect

Higher Coriolis effect  are seen when the speed is high or long distances are traversed.

Why are annual temperature ranges in the Southern Hemisphere generally smaller than those in the Northern Hemisphere?

Answers

Annual temperature ranges in the Southern Hemisphere generally smaller than those in the Northern Hemisphere because there is a higher rate of the water surface in the Southern Hemisphere.

Water is a prominent absorber of radiation and slower radiator of heat than land Environments in the southerly region which overall tend to be lightly moderate than those in the northerly region. This is because the southerly hemisphere has significantly more beach and less land. Water warms up and freezes down more slowly than land. The southerly hemisphere is also significantly less contaminated than the northerly hemisphere because of lower population densities,  lower levels of industrialization, and smaller land sizes.

Why are Annual temp ranges in the southern hemisphere generally smaller than those in the northern hemisphere? Answer:there is more water
