Question

The angle at which the sunrays fall on the earths surface is called​

Answer 1

Answer:

ans. Angle of incidence

Explanation:

as the sun rays are falling directly into the earth therefore the rays are incident

Answer 2

Answer:

The angle at which the sunrays fall on the earths surface is called as angle of incidence.

Explanation:

The angle which is formed by the sun rays when hitting the Earth is technically and generally known as the angle of incidence. Rays when striking the planet’s surface from the directly overhead that is, at an angle of 90° is measured from the horizon are the most intense.

At most of the times and locations around the globe, the sun forms an angle with the horizon less than 90° that means, usually the sun sits lower in the sky.

The smaller the angle of the rays of sunlight, the greater the surface area of the light over which the sun’s rays spread. This effect reduces the sun’s intensity in any one place. For example, at a 60 degree angle of incidence, solar radiation covers a 40 percent greater area and is 45 percent less intense than at the maximum angle of incidence of 90°. This is because the sunrays angle varies from place to place. At equator the sun rays are perpendicular vertically. While in the poles suns intensity decreases.
