What is warmest layer in atmosphere?
The thermosphere (above 80 km above the Earth's surface) is the hottest layer. The temperature as high as thousands of degrees as the few molecules that are present in the thermosphere receive large amounts of energy from the Sun. However, it would actually feel very cold as very few molecules will hit our skin and transfer enough energy make us feel the heat..
What atmosphere layer has highest temperature?
The thermosphere is the "hottest" layer of the Earth's atmosphere. As the outermost layer with substantial numbers of molecules, it receives the most direct radiation from the Sun. However, despite the high molecular temperatures measured in this layer (as high as 2500°C or 4530°F), the matter is tenuous compared to the lower atmosphere. An object within the thermosphere would absorb very little total heat energy. Almost all satellites, and the International Space Station, orbit within the thermosphere. The layer periodically varies in thickness, stretching from about 80 kilometers in altitude to between 250 and 500 kilometers. The thermosphere.
Why is there little heat retained in the thermosphere?
The thermosphere is the final layer of the atmosphere. Because it is so close to the sun, and there is nothing to protect it from the sun's heat, it is very warm.
Why is there little heat retained in the warm thermosphere?
The thermosphere is the final layer of the atmosphere. Because it is so close to the sun, and there is nothing to protect it from the sun's heat, it is very warm.
Why is it necessary to use special instruments to measure the temperature of the atmosphere in the thermosphere layer?
The thermosphere is the last layer of the atmosphere. Special instruments are needed to measure its temperature because there are very few particles in the thermosphere that would strike a conventional thermometer to heat it.
What is the major way in which heat energy is spread through the atmosphere?
One way that heat energy is spread through the atmosphere is through radiation. Conduction and convection are two other ways that heat energy is spread through the atmosphere.
What layer in the atmosphere traps heat?
the troposphere
What do greenhouse gases reflect?
Greenhouse gases don't reflect anything. They absorb energy from incoming sunlight and warm up. The warm gas molecules then share the heat with all other molecules in the atmosphere. Many people think there is a layer of greenhouse gas "up there" that reflects the heat back to Earth. This is not the case, The gases are mixed all through the atmosphere, not concentrated in a layer.
What is its main function in the atmosphere?
An atmosphere is a gaseous layer round a planetary body, held there by the gravity of the said body. Atmospheres being fluids spread heat round planets from hot areas to cooler areas.
How does heat affect the molecules in a substance?
They rapidly vibrate. Yes, they do, but how rapidly depends on the amount of heat (kinetic energy) added to the molecules. If solid, they will eventually melt depending on which solid and what its melting point is. If liquid, they will eventually become a gas or vapor, and a gas will expand indefinitely into the atmosphere if not contained within something. Think of water: ice heats to liquid water which in turn becomes steam (vapor) which goes out into the atmosphere unless it is contained. If the container cannot expand and the water vapor (or any other gas) continues to be heated, eventually the gas will cause the container to explode because the internal pressure will exceed the ability of the container to hold it.
Which layer in the atmosphere absorbs warmth due to ozone so temperatures rise?
Stratosphere is the layer. It absorbs the heat.
What is the hottest layer of the Earth's atmosphere?
The thermosphere is the hottest layer of Earth's atmosphere. The molecules there are directly exposed to solar radiation and high-energy cosmic rays. However, there are so few molecules by volume that the specific heat is virtually zero. The thermosphere is generally located 85 to 500 km above the Earth, and the International Space Station orbits in the outer thermosphere (330 to 450 km altitude).

The storage of heat in the lower layer of the atmosphere produced by certain heat absorbing gases is called the?
the greenhouse effect
What atmosphere layer does temperature decrease with increasing height?
In the troposphere (the layer of the earth that we live in), the temperature decreases with increasing height. The troposphere contains approximately 80% of the atmosphere's mass and 99% of its water vapour and aerosols.As you increase height, you reach areas of the atmosphere that have fewer and fewer air molecules (which means the air is less dense) because gravity is keeping the majority of air molecules closer to the ground. So, at higher altitudes, the air is less able to store heat.
Is the troposphere the warmest layer of the atmosphere?
By its heat energy content, yes. But the thin upper atmospheric layer called the thermosphere is hotter, considering the average temperature of the individual molecules there, which can exceed 1500 degrees Celsius.
How is heat energy spread throughout the atmosphere?
it is spread by a fire being started because the wind can blow it through the atmosphere because smoke is just like oxygen and it is light .
