What is the source of radiation for both the earth's atmosphere and greenhouse?
The primary source of radiation for both the Earth's atmosphere and greenhouse effect is the Sun. Solar radiation enters the Earth's atmosphere, warming the surface. Greenhouse gases in the atmosphere trap some of this heat, preventing it from escaping back into space.
What is the name of the natural cycle in which water travels from the earth to the atmosphere and back again?
Answer :Water is continuously moving form the Earth's surface into the air, and from the air back onto the Earth's surface. This continuous movement of water is called the hydrologic cycle, or water cycle.
Why does it get freezing cold on the planet Mercury at night?
There is no atmosphere to retain the heat that Mercury receives from the Sun, so it is all lost from the night side, radiated back into space. The same surface that reaches over 400 °C in the sun then plummets to -184 °C in a night that lasts 88 Earth days. The same situation occurs on the Earth's moon, where the temperature is scorching in the Sun and icy on the part that is in darkness.
Why are cloudy days cooler but cloudy nights warmer than the clear ones?
During a clear night, as heat absorbed by the earth during the day seeps out, the atmosphere allows the heat to pass through. During a cloudy night, however, the clouds catch and retain the heat in the atmosphere.Clouds trap heat being reflected from the earthThe heat radiation lost from the earth gets reflected by the clouds back to the earth, warming it. Whereas on a clear night it just escapes into space.
What occurs when anaerobic bacteria break down nitrates and release nitrogen gas back into the atmosphere?
When anaerobic bacteria break down nitrates, they can denitrify the nitrates and release nitrogen gas (N2) back into the atmosphere. This process is called denitrification and it helps return nitrogen to the atmosphere in its inert form.
How can water in the atmosphere cycle back to the surface of the Earth?
Water in the atmosphere precipitates. And in this manner it returns back to earth's surface.
How can the sun continue to heat the atmosphere at night?
Some atmosphere from the terminator pours over the horizon, and there might be a tiny bit of warmth from sunlight reflected off the lunar surface. However, essentially, the sun does not warm the atmosphere at night. This is why, on average, the atmosphere tends to cool all night long, reaching its coldest point just before sunrise.
Why is it colder at night than day?
At night, the Earth's surface loses heat to the atmosphere through radiation. Without the sun's warmth during the daytime, the Earth's surface cools down, leading to lower temperatures at night. Additionally, there is less solar radiation reaching the Earth's surface at night, contributing to the drop in temperature.
What keeps earth warm after dark?
The Earth is kept warm after dark by the atmosphere acting as a blanket. The atmosphere traps some of the heat received from the Sun during the day, preventing it from escaping back into space at night. This process is known as the greenhouse effect.
Which term best describes how the earth's atmosphere is heated?
m
What layer of the earth's atmosphere where the radio communication are reflected back to the earth?
I believe it is the Ionosphere.
How does heat enter the atmosphere?
Heat enters the Earth's atmosphere primarily through the absorption of sunlight by the Earth's surface, which warms up and then radiates heat back into the atmosphere. Other sources of heat entering the atmosphere include human activities such as burning fossil fuels and deforestation, which release heat-trapping greenhouse gases.
What is the ideal radiation budget?
Radiation budget is Earth's atmosphere. The Earth's atmosphere has more solar energy than it radiates back to space.
How does the eaths rotation cause temperature differences during day and night?
Because the earth didn't have an atmosphere back then That answer is also right but their is another slip to it, the slip to it is that, their is a seasonal change in the atmosphere and if they didn't have a satellite the seasons wouldn't change, so that is also why we have satellites for electricity and the seasons...!
What happens to most of the sunlight that reaches Earth?
About 50% is absorbed by Earth's surface, about 25% is reflected by clouds, dust, and gases in the atmosphere, about 20% is absorbed by gases and particles in the atmosphere and about 5% is reflected by the surface back into the atmosphere. Also some absorbed energy is radiated back into the atmosphere.
What heats up the earth during the day and what cools it down at night?
During the day, the Earth is heated primarily by the sun's radiation. At night, the Earth cools down as it releases the heat absorbed during the day back into the atmosphere through a process called radiation cooling.
Which bacteria can release nitrogen from nitrates and nitrites in the soil back to the atmosphere?
The bacteria that can release nitrogen from nitrates and nitrites in the soil back to the atmosphere are called denitrifying bacteria.
