What heats the lower atmosphere?
The lower atmosphere is heated by the ground, which is heated by sunlight.
How can a particularly violent volcanic eruption impact global temperature?
Ash released from a volcanic eruption can enter the upper atmosphere where it can reflect sunlight. Volcanoes formed the early atmosphere of the planet, so they definitely can have global impact, an increase in agriculture does not signify a significant change in global temperature.
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 part of the atmosphere causes daylight to occur?
it isn't actually in the atmosphere. it's the sun. Hence the term sunlight.
Why are polar regions cooler than the equator?
Answer:sunlight strikes the poles at an oblique angle. From the polar regions, the sun is low in the sky, so that the sunlight hits the earth at a low angle, as it does for us in the morning and evening. This low angle means that the sunlight is more spread out, and thus warms the surface less. The polar regions of earth are not cooler because they are farther away from the equator, and they are not cooler because they are farther from the sun. The poles are only about 3000 km farther from the sun than is the equator at noon. This is about 0.002% of the earth-sun distance -- hardly significant.
What layer of the atmosphere is first struck by sunlight?
The exosphere is the layer of the atmosphere first struck by sunlight
What causes sunlight to pass through the upper atmosphere?
Sunlight can pass through atmosphere. But not the part containing UV rays.
What heats the lower atmosphere?
The lower atmosphere is heated by the ground, which is heated by sunlight.
A rainbow forms when sunlight shines on water in what?
A rainbow forms when sunlight shines on water in the atmosphere.
What do you need in atmosphere to sustain life?
oxygen and sunlight
What was the trigger that caused reactions to occur in the atmosphere?
sunlight
Why it is cold above the atmosphere?
It is not necessarily cold above the atmosphere. In direct sunlight, it can be quite hot.
what happens to sunlight as it enters the earth's atmosphere?
Sunlight experiences some degree of scattering (technically, Rayleigh Scattering) as it passes through the atmosphere, which causes the sky to appear blue and the sunlight to appear yellow. Some of the sunlight encounters clouds, while some reaches the ground.

How would a lunar eclipse look if Earth had no atmosphere?
We would not get the same redness that we do from sunlight shining through our atmosphere.
