All The Radiation Emitted By The Earth Ends Up Escaping Into The Atmosphere

How did earths atmosphere end up so different. The energy does not move closer to space because it is not directional.

Each plot serves as an estimate of how much radiation will pass through a 3 km layer of the atmosphere from below.

All the radiation emitted by the earth ends up escaping into the atmosphere. The spectrum of radiation emitted by a body with temperature. Earths atmosphere is transparent to visible photons emitted by the sun wavelengths from 03 08 mm so these photons pass through the atmosphere and are absorbed by the surface. Only half of the photons emitted by the surface end up escaping to space the other half are.

The 0 km plot shows that almost all the long wave radiation emitted by the earth is absorbed in the first 3 km of the atmosphere except for wavelengths between 8 mm and 13 mm. Learn vocabulary terms and more with flashcards games and other study tools. Heres how the dynamic works.

In fact because of its abundance in the atmosphere water vapor causes about two thirds of greenhouse warming a key factor in keeping temperatures in the habitable range on earth. Start studying astronomy 3. In near earth space the slow solar wind is observed to have a velocity of 300500 kms a temperature of 10 5 k and a composition that is a close match to the corona.

When radiation is re emitted in the atmosphere it moves in all directions. But as temperatures warm more water vapor evaporates from the surface into the atmosphere where it can cause temperatures to climb further. The solar wind is observed to exist in two fundamental states termed the slow solar wind and the fast solar wind though their differences extend well beyond their speeds.

The way heat moves toward the outer atmosphere is either through convectional currents or long wave infrared radiation which is not affected by greenhouse gases. Solar uv breaks up h2o into h and o h lost by thermal escape.
