Why does the U.S. get involved in conflicts in the Middle East?

Mariana [72]

U.S. involvement in the affairs of countries in the Middle East is a long, complicated, and tenuous history. The simple answer is that the United States has been involved in conflicts in the Middle East because of its relationships with countries and governments in that region and more broadly its desire to assert its influence in this vital region of the world that has unfortunately been rife with conflict. During the Cold War the Middle East was very much a battleground between the U.S. and the Soviet Union in the fight for resources, influence, and power. This has continued today as new rivalries and conflicts have developed even without the Soviet Union.

In relation to the structure and size of the sun how are the following achieved absorption , reflection,transmission,scattering

Setler79 [48]

Answer:

Explanation:

Scattering of solar radiation within the atmosphere also accounts for a reduction of energy reaching Earth. Atmospheric gas molecules and aerosols deflect solar radiation from its original path, scattering (reflecting) some radiation back into deep space and some toward Earth's surface.

Once the sun's energy reaches earth, it is intercepted first by the atmosphere. A small part of the sun's energy is directly absorbed, particularly by certain gases such as ozone and water vapor. Some of the sun's energy is reflected back to space by clouds and the earth's surface.

A Quick Overview of Light Absorption

In absorption, the frequency of the incoming light wave is at or near the energy levels of the electrons in the matter. The electrons will absorb the energy of the light wave and change their energy state.
