Explain how radiant energy reaches earth

WebMore often, though, precipitation reaches the Earth's surface, adding to the surface water in streams and lakes, or infiltrating the soil to become groundwater. ... Evaporation occurs when radiant energy from the sun heats water, causing the water molecules to become so active that some of them rise into the atmosphere as vapor. WebThe intensity of solar radiation at the top of Earths atmosphere is l 370 W/m3. Assuming 60% of the incoming solar energy reaches Earths surface and assuming you absorb 50% of the incident energy, make an order-of-magnitude estimate of the amount of solar energy you absorb in a 60-minute sunbath.

WebMost solar energy occurs at wavelengths unsuitable for photosynthesis. Between 98 and 99 percent of solar energy reaching Earth is reflected from leaves and other surfaces and absorbed by other molecules, which convert it to heat. Thus, only 1 to 2 percent is available to be captured by plants. The rate at which plants photosynthesize depends on the … WebSolar radiation that is not absorbed or reflected by the atmosphere (for example by clouds) reaches the surface of the Earth. The Earth absorbs most of the energy reaching its surface, a small fraction is reflected. In total approximately 70% of incoming radiation is absorbed by the atmosphere and the Earth’s surface while around 30% is reflected back … WebNov 10, 2024 · Convection is when energy is transferred via currents in a fluid.
