Answer 1

Answer:

HEY MATE YOUR ANSWER IS -   OPTION (A) SMALL ANGLE

IF IT HELPS YOU SO PLEASE PLEASE MARK MY ANSWER AS BRAINLIEST

Answer 2

The correct answer is OPTION A: Small-angle.

• Radiation, a form of energy, is received by the earth from the Sun.
• Because the angle of incidence is smaller, the polar area receives less solar radiation than the equator.
• At the North Pole, the sun's rays are less focussed and do not directly hit the Earth's surface.
• Around 30% of incoming solar energy is reflected by the Earth.
• Solar light reflects at an acute angle in polar regions.
• The more atmosphere sunlight must strike through, the steeper the angle at which it strikes.
