A little over 8 minutes
The speed of light is 299,792,458 m/s (we'll use 3x10^8 m/s)
The average distance from the Earth to the Sun is 149.6x10^9 m
time = distance/velocity
t ≈ (149.6x10^9 m)/(3x10^8 m/s)
t ≈ 498.667 s
minutes = 498.667 s/60
t ≈ 8.3 minutes
Earth's oceans radiate infrared energy into space as part of Earth's energy budget. This energy is a result of the absorption of solar radiation by the oceans, which is then re-radiated back into space as heat.
Solar energy that heats the surface is re-radiated as infrared radiation, some of which is absorbed by the atmosphere in the process. Water vapor, methane, and carbon dioxide can all collect this re-radiated energy to some extent.
Energy radiated from the surface of the sun visible during a solar eclipse appears in the form of the corona, which is the outer atmosphere of the sun. This is a faint, glowing halo of plasma that extends millions of kilometers into space and is only visible during a total solar eclipse when the moon blocks the brighter light from the sun's surface.
Yes, among other ways, solar energy is radiated. That is what heats up the Earth and the other planets, mostly.
This process is called the greenhouse effect. Greenhouse gases, such as carbon dioxide and water vapor, trap heat radiated from the Earth's surface, leading to a warming of the atmosphere. This effect is essential for keeping the Earth's surface warm enough to support life.
the greenhouse
The energy is radiated equally in all directions into a sphere with a radius of 150 million kilometres, which has a surface area. On that sphere sits the Earth with a radius of 6378 kilometres, which has a circular cross-section area which intercepts part of the total energy. The ratio of the two areas answers the question.
Two billionths. It might seem really small, but coming from the sun, it is a lot!
infared
Infrared radiation from the sun warms the Earth's surface. This heat energy is then radiated back into space as longwave infrared radiation. This process is known as the greenhouse effect.
50%
Most solar energy that reaches Earth's atmosphere is absorbed by the surface of the Earth, such as the land, oceans, and vegetation. This absorption heats up the Earth's surface and is then radiated back into the atmosphere as heat energy.
Of the Sun's energy reaching Earth's atmosphere, just under 60% reaches the Earth's surface. Only a small fraction of the Sun's energy reaches Earth, of course. In fact it's only about 0.000000045 percent. So, the answer to the question is: about 0.000000025 percent.
About 50% of the sun's radiation that reaches Earth's atmosphere is absorbed by the Earth's surface. The remaining energy is either reflected back to space or absorbed by the atmosphere.
Water vapor, carbon dioxide, methane, and other gases absorb most of the energy that is radiated from Earth's surface.
Water vapor, carbon dioxide, methane, and other gases absorb most of the energy that is radiated from Earth's surface.
The energy from the sun that is absorbed by the Earth's surface is converted into heat. This heat is then re-radiated back into the atmosphere, contributing to the Earth's overall temperature and driving weather patterns and climate systems.
