Why does the equator receive greatest amount of energy from Sun and effects of shape of Earth angle of reflection and albedo and equator get most energy?
The Sun's rays strike Earth's surface most directly at the Equator. Near the poles, the Sun's rays strike the surface at a slant. This spreads the rays over a wide area. The more focused the rays are, the more energy an area receives. The equator gets the most direct sunlight year-round. The angle of sunlight hitting the equator is more direct than it is at the poles, so the poles receive less direct sunlight. Because Earth is a sphere, not all part of the Earth receives the same amount of solar radiation. More solar radiation is received and absorbed near the equator than at the poles. Near the equator, the Sun's rays strike the Earth most directly, while at the poles the rays strike at a steep angle.
At high angles the sun's radiation is most intense. This is why noon or the early afternoon is often the warmest time of day. At the equator, the direct angle with which light reaches the surface results in more of the energy being absorbed rather than reflected. Finally, the poles reflect more solar energy than other parts of the Earth because the poles have a higher albedo. When the sun's rays strike Earth's surface near the equator, the incoming solar radiation is more direct (nearly perpendicular or closer to a 90˚ angle). Therefore, the solar radiation is concentrated over a smaller surface area, causing warmer temperatures. The Spherical Shape of the Earth because the Earth is a sphere, the surface gets much more intense sunlight (heat) at the equator than at the poles. During the equinox (the time of year when the amount of daylight and nighttime are approximately equal), the Sun passes directly overhead at noon on the equator.Because of the Earth's spherical shape, sunlight hits the equator directly year-round, unlike the North and South Poles. The sunlight is most indirect when hitting the North and South Poles; therefore, it is coldest there. At the equator, all days of the year have the same number of hours of light and dark. Between the two tropics zones, which include the equator, the sun is directly overhead twice per year. Outside the tropic zones, whether to the south or north, the sun is never directly overhead. There are always twelve hours of daytime and twelve hours of night-time at the equator, except for two minor effects that increase daytime by about eight minutes. Due to the spherical shape of the Earth, sunlight falls on different parts at different angles. Direct and focused sun rays falls on the equator and hence, the regions here are hotter and warmer. The Northern Hemisphere receives the maximum intensity of the sun's rays, while the angle of sunlight decreases in the Southern Hemisphere. The equator gets the most direct sunlight year-round. The angle of sunlight hitting the equator is more direct than it is at the poles, so the poles receive less direct sunlight.It radiates light and heat, or solar energy, which makes it possible for life to exist on Earth. Plants need sunlight to grow. Animals, including humans, need plants for food and the oxygen they produce. Without heat from the sun, Earth would freeze. The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs.

The Northern Hemisphere receives the maximum intensity of the sun's rays, while the angle of sunlight decreases in the Southern Hemisphere.The Sun's path is highest in the sky on the equinoxes and lowest on the solstices. This results in two periods of maximum sunlight centering on the equinoxes and two period of minimum sunlight at solstice times each year. 23. At the equator the daily period of daylight is the same day after day. The more slanted the sun's rays are, the longer they travel through the atmosphere, becoming more scattered and diffuse. Because the Earth is round, the frigid Polar Regions never get a high sun, and because of the tilted axis of rotation, these areas receive no sun at all during part of the year.At high angles (65o-90o) the sun's radiation is most intense. This is why noon or the early afternoon is often the warmest time of day. When the sun's rays strike Earth's surface near the equator, the incoming solar radiation is more direct (nearly perpendicular or closer to a 90˚ angle). Therefore, the solar radiation is concentrated over a smaller surface area, causing warmer temperatures. A lot of the solar energy that reaches Earth hits the equator. Much less solar energy gets to the poles. The difference in the amount of solar energy drives atmospheric circulation. The poles reflect more solar energy than other parts of the Earth because the poles have a higher albedo . The albedo refers to reflectivity of a surface. Lighter surfaces are more reflective than darker surfaces and therefore have a higher albedo. The equator receives the most direct sunlight because sunlight arrives at a perpendicular (90 degree) angle to the Earth. Sunlight rays are concentrated on smaller surface areas, causing warmer temperatures and climates.
