How does sunlight reach the Earth surface?
Remember, the Earth follows an elliptical orbit around the Sun, ranging from 147 million to 152 million km. They start off as gamma radiation and then are emitted and absorbed countless times in the Sun’s radiative zone, wandering around inside the massive star before they finally reach the surface.
Where does the sun rays reach the Earth directly?
the equator
Different parts of Earth’s surface receive different amounts of sunlight. The sun’s rays strike Earth’s surface most directly at the equator. This focuses the rays on a small area. Because the rays hit more directly, the area is heated more.
How long does the Sun rays take to reach Earth?
499.0 seconds
Light travels at a speed of 299,792 kilometers per second; 186,287 miles per second. It takes 499.0 seconds for light to travel from the Sun to the Earth, a distance called 1 Astronomical Unit.
Why does it receive slanting rays from the sun?
The Earth receives the greatest heat input from the Sun when the Sun’s rays are directly overhead during the daylight hours. The polar regions are cold, not because of distance from the Sun but because they always receive the Sun’s energy at low slant angles so the energy gets spread over a greater area.
Why does it receive direct rays from the sun?
The hemisphere that is more directly facing the Sun at a given point in Earth’s orbit receives more of the Sun’s energy. When the Sun is directly over your head, you are receiving the Sun’s most direct rays.
Where will the sun rays fall from slanting?
Explanation: The sun rays fall vertically , as the latitude increases , the rays become more and more slanting . vertical rays spread over a larger land area than slanting rays , also they passes through the thicker layer of the atmosphere which absorbs a large part of their heat .
Which temperature receives slanting rays?
Torrid zone receives almost vertical rays of the sun and temperate zone and frigid zone receive slanting rays of the sun.
At which position is the Earth receiving direct rays of the sun on Equator?
Explanation: On 21st March and September 23rd, direct rays of the sun fall on the equator. At this position, neither of the poles is tilted towards the sun; so, the whole earth experiences equal days and equal nights. This is called an equinox.
Is the sun always over the equator?
Because the sun’s rays hit the earth’s surface at a higher angle at the equator. e. Because the sun is always directly overhead at the equator.
