Energy in the Atmosphere | Earth Science
Much more energy from the Sun reaches low latitudes (nearer the equator) than high latitudes (nearer the poles). These differences in insolation –- the amount of solar radiation that reaches a given area in a given time — cause the winds, affect climate, and drive ocean currents.
Reflection of light
Reflection is when light bounces off an object. If the surface is smooth and shiny, like glass, water or polished metal, the light will reflect at the same angle as it hit the surface. This is called specular reflection.

Sunlight is a portion of the electromagnetic radiation given off by the Sun, in particular infrared, visible, and ultraviolet light. On Earth, sunlight is scattered and filtered through Earth''s atmosphere as daylight when the Sun is above the horizon. When direct solar radiation is not blocked by clouds, it is experienced as sunshine, a combination of bright light and radiant heat (atmospheric). When blocked

About 30% of the available solar radiation at the top of the atmosphere is reflected or scattered back to space by particulates and clouds before it reaches the ground.
The Sun''s Energy: An Essential Part of the Earth System
If we ignore the other wavelengths and focus just on the visible light from the Sun, we can use a unit called a lumen to measure brightness. The Sun is mind-bogglingly bright, shining at about 36 octillion (3.6 x 10 28 ) or 36 thousand …
How do greenhouse gases trap heat in the atmosphere?
1 This name is a little misleading. A real greenhouse traps heat because its glass stops the warm air inside from transferring heat to the colder surrounding air. Greenhouse gases don''t stop heat transfer in this way, but as this piece explains, in the end they have a
4.7: Eclipses of the Sun and Moon
At position 4, the Moon is farther away and thus cannot cover the Sun completely; a ring of light thus shows around the Sun, creating what is called an "annular" eclipse. If the path of the Moon in the sky were identical to the path of the Sun (the ecliptic), we might expect to see an eclipse of the Sun and the Moon each month—whenever the Moon got in front of the Sun or into the shadow ...
17.1: The Brightness of Stars
Even scientists can''t calculate fifth roots in their heads, so astronomers have summarized the above discussion in an equation to help calculate the difference in brightness for stars with different magnitudes. If m1 and m2 are the magnitudes of two stars, then we can calculate the ratio of their brightness (left( frac{b_2}{b_1} right)) using this equation:

When the angle of incidence is at a 90 angle to the Earth (called direct or perpendicular rays), approximately 75% of the radiation emitted from the Sun reaches the surface of the Earth. Throughout the year, the angle of the Sun''s rays are low (less than 25°) at the poles, compared to those closer to the equator.
