Question 11

Why is the energy of the sun less intense at the poles as compared to the equator?

Accepted Answer

A)  The tilt of the Earth moves the poles farther away from the most intense sunlight.
B)  Because the Earth is spherical and the sun shines toward the equator,the sunlight is more spread out at the poles and therefore less intense.
C)  The movement of wind across the face of the Earth pulls cooler air from over the oceans and blows it toward the poles.This cools the poles while leaving the region around the equator hot.
D)  The movement of cool waters in ocean currents flows away from the equator and cools the air farther from the equator,causing the polar regions to be cooler than the equatorial region.
E)  The Earth shifts in its orbit periodically and at times it moves farther from the sun.This movement coincides with times that the Earth is tilted toward the sun so the poles never receive as much sunlight as the equator.F) A) and C)
G) All of the above

Accepted Answer

A)  Both are found close to coniferous forests.
B)  One is cold and dry because it is at a high latitude and the other is cold and dry because it is at a high altitude.
C)  Both are located in areas of intense sunshine.

The Earth is actually slightly farther from the sun during the period when the Northern Hemisphere is having summer.How can this be explained?

Accepted Answer

A)  The sun grows more powerful on a half-year cycle.
B)  There is a six-month lag phase between sunlight being absorbed and lost.
C)  The tilt of the Earth presents the Northern Hemisphere in a more perpendicular angle and this increased sunlight per surface area more than offsets the decrease from added distance.
D)  There must be some mistake in measuring the Earth's orbit because if the Earth was farther away,we would be cooler.
