What factors contribute to the decrease in the amount of energy reaching earth's surface?
There are several factors that contribute to the decrease in the amount of energy reaching earth's surface. These are: reflection, scattering, absorption by gases and aerosols in the atmosphere, and cloud cover.
What are the limitations in comparing the earth's atmosphere to a greenhouse?
The scale is the most limiting factor in comparing the Earth's atmosphere to that of a greenhouse. The type of surface that sunlight first encounters is an important factor. Forests, grasslands, ocean surfaces, ice caps, deserts, and cities all absorb, reflect, and radiate radiation differently. Sunlight falling on a white glacier surface strongly reflects back into space, resulting in minimal heating of the surface and lower atmosphere. Sunlight falling on a dark desert soil is strongly absorbed, on the other hand, and contributes to significant heating of the surface and lower atmosphere. Cloud cover also affects greenhouse warming by both reducing the amount of solar radiation reaching the earth's surface and by reducing the amount of radiation energy emitted into space.
What location on earth receives most direct sunlight?
On a yearly basis the Earth receives the same amount of sunlight on its total surface. The distribution of light to dark periods is different by latitude and time of year
Why do clouds lessen the amount of heat received by the earth?
Because the rays of the sun bounces off the clouds and back into space before reaching the surface of the Earth.
What do direct rays have to do with it being warmer in summer than winter?
If the sunlight is coming directly down upon the surface then it will concentrate the energy. If the sunlight was at an angle the same amount of light is spread over a larger area and it will be colder.
Does cloud cover effect the amount of sunlight that reaches the earth's surface?
Cloud cover blocks incoming solar radiation from reaching the earth's surface
What factors could affect the amount of sunlight reaching the earth's surface and decrease the flux of solar energy?

What are the conditions influencing crop cultivation?
amount of precipitation throughout the growing season and the amount of daily sunlight
Why does the rain forest grow in layers?
It grows in layers because of the amount of sunlight reaching each part of the forest. Since the emergents are the highest they receive the most amount of sunlight and hence the top layer. As the layers decrease so does the amount of sunlight and hence different heights of the rainforest.
Why are jungles sunlight short?
They are no shorter of longer than any other area on the same latitude. However, the foliage or canopy will reduce the amount of sunlight reaching the jungle floor.
which of these changes does a submarine encounter as it returns from the bottom of the ocean to the surface of the ocean?
The amount of sunlight increases
Why do day and night change throughout the year?
Because of the amount of sunlight changing from the earth being on its axis
Why do day and night change length throughout the year?
Because of the amount of sunlight changing from the earth being on its axis
How do aerosol particles affect insolation?
They scatter sunlight, reducing the amount that reaches the surface as direct radiation (increasing the amount that reaches as diffuse).
What are the three are the main influences on the input of solar energy to the Earth?
The three main influences on the input of solar energy to the Earth are the distance between the Earth and the Sun, the angle at which the sunlight reaches the Earth's surface (known as the solar angle), and the amount of atmosphere the sunlight has to travel through before reaching the Earth's surface. These factors determine the intensity and distribution of solar energy received by different parts of the Earth.
How do the temperatures at different levels vary in lakes?
Because as the depth increases in a lake, the amount of sunlight reaching that point also decreases. Thus, as you go lower in a lake, the temperature decreases because there is less sunlight -- the same reason shadows are colder than sunlight.
