There are two reasons: the angle of insolation and the albedo of the surface.*

The Earth's surface is curved, so that while one area receives the sunlight perpendicularly to the surface, other areas (notably higher latitudes) receive the sunlight at an angle. Not only does this increase refraction, but also scattering, because the sunlight travels through a greater volume of air on the way to the surface.

The albedo is the relative reflectivity of an area of the Earth's surface, or of cloud layers covering the surface. The higher the reflectivity, or the greater the cloud cover, the less solar warming of the surface. However, clouds at night can also trap infrared radiation re-rediated by the Earth, in some cases compensating for the reduced solar heating. (In the worst case scenario, daytime clouds would block the sunlight, then dissipate at night.)

Ice and snow are more reflective than other surfaces such as rocks, trees, and buildings, so winter sunlight provides even less heating when temperatures are very low and there is more snow on the ground.

* Water surfaces absorb more heat than land surfaces. But this is less a case of uneven heating than uneven absorption.

Uneven heating of the Earth's surface is due primarily to the position of the what?

Uneven heating of the Earth's surface is primarily due to the position of the sun. The angle at which sunlight strikes the Earth's surface varies depending on the latitude, leading to differential heating across the globe.


What causes uneven heating of the earth?

Uneven heating of the Earth's surface is primarily caused by variances in the angle of the sun's rays, due to the Earth's tilt on its axis. This tilt results in different amounts of solar energy reaching different parts of the Earth, leading to variations in temperature. Additionally, factors such as cloud cover, albedo, and ocean currents also contribute to uneven heating patterns.


Uneven heating of the Earth's surface is due primarily to the position of the?

Uneven heating of the Earth's surface is primarily due to the position of the Earth in relation to the sun. This is influenced by factors such as the angle of sunlight, the amount of atmosphere sunlight passes through, and the curvature of the Earth.


The main cause of global convection currents is?

uneven heating of the Earth's surface by the sun, which creates temperature and density variations in the air and water. These variations drive the movement of air and water around the globe in convection currents.


What does uneven heat from sun cause to the earth?

Uneven heating from the sun causes variations in temperature across the Earth's surface, leading to the formation of weather patterns such as winds and ocean currents. This helps drive the global climate system and influences local weather conditions.
