Four locations on earth receive sunlight at different angles. at which of the following angles will the intensity of sunlight received be the least? 90° 75° 50° 25°

The answer is 25 degree, because when the sun is directly overhead, its rays strike the earth at a 90 degree angle. The closer to 90 degrees the rays are, the more concentrated they are and the greater is the heat they produce on the earth's surface. The solar heat reach the surface of the earth becomes less intense as the angles of the rays decreases.
