What factors affect the angle at which sunlight hits earths surface?

Answer 1

it depends where you are on the glob.if you are near the equator you will receive more isolation than a location in the northern hemisphere. It also depends on the angel of which you are located.

Answer 2

1. Angle of incidence, the angle at which the sun rays from the sun strike earth's surface.if the rays strike the earth at angle less than 90 degrees the energy spread over large portion of the earth. But when the ray strike at exactly 90 degrees the energy concentrate on small area.

2. Day leghth refers to the duration of the sunlight, longer days allows more insolation and more heat is absorbed.

3. Atmospheric obstruction;the longer the incident rays passes through the atmosphere the more the weaker the intensity of energy at the earth's surface.

4. latitudinal sunshift.sun rays normally shift from northward and southwards during the course of the year.therefore low latitude receive surplus energy with more coming energy than outgoing energy

Answer 3

The amount of sunlight received by anywhere on the planet is influenced primarily by two factors: altitude and latitude. The deeper one is in the atmosphere (i.e. the closer one is to sea level) the more atmosphere there is to scatter the incoming light from the sun. Thus, at higher elevations, the light concentration received by the ground is closer to the actual amount emitted by the sun. Latitude, on the other hand, affects sunlight because of the geometry of the planet. Since Earth is an oblate spheroid, if a cylinder of light were to shine straight down on it, the shape that would appear on the surface would be circular. However, as the angle of inclination decreases, this shape starts to turn elliptical. Thus, the same "volume" of light is shining over a wider surface area and so the light is less concentrated. Basically, higher altitude, lower latitude areas receive a great amount of sunlight, while lower altitude, higher latitude areas receive a comparatively small amount.

Answer 4

The time of year - air pollution - and the amount of cloud cover.

Answer 5

because!
