With regard to the Earth being an open or closed system, what form of energy enters Earth’s system? Explain what becomes of this energy once it enters the system.

Solar energy, uv rays, radiation, all those types of energy get into earth and are absorbed by things such as land and wanted, while most of the energy is reflected back to the atmosphere.
Earth receives cosmic radiation from space and sunlight. Most harmful insolation (like x-rays and ultraviolet light) is stopped by particles in the atmosphere (mainly in the thermosphere and stratosphere).About 50% of sunlight getting to Earth is absorbed by the surface. 19% is absorbed by atmosphere and 31% is reflected back to space
The energy that enters the earths system is sunlight. When it enters th system 50% is absorbed into the earths surface, 19% is absorbed by the atmosphere, and 31% is reflect back into space.

Sunlight is the energy that enters earths system and it heats the planet to sustain life on earth.

One type of energy that can enter Earths system is sunlight, it helps to warm our planet and help our plants grow.

sunlight in radiant energy form, and once it enters the system it becomes heat energy, which can be absorbed into land and water.

Sunlight is one of the energies that enter our planet and once it is here it heats up the planet keeping it warm enough for life

Sunlight is one form of energy that can enter the earths atmosphere which provides energy to the plants and warms the planet to livable temperatures.
