Which is hotter thermosphere or exosphere?
The thermosphere is directly above the mesosphere and below the exosphere. The thermosphere is typically about 200° C (360° F) hotter in the daytime than at night, and roughly 500° C (900° F) hotter when the Sun is very active than at other times.
Which is the lowest layer of the atmosphere answers?
The troposphere
The troposphere is the lowest layer of our atmosphere.
Which is the lowest layer of the atmosphere give answer?
Troposphere
Troposphere. The troposphere is the lowest layer in the atmosphere. It extends upward to about 10kms above sea level starting from ground level.
Which atmospheric layer is the densest Why?
In the troposphere, temperatures typically go down the higher you go, since most of the heat found in the troposphere is generated by the transfer of energy from Earth’s surface. The troposphere is the densest atmospheric layer, compressed by the weight of the rest of the atmosphere above it.
What is the coldest layer of Earth’s atmosphere?
the mesosphere
Located between about 50 and 80 kilometers (31 and 50 miles) above Earth’s surface, the mesosphere gets progressively colder with altitude. In fact, the top of this layer is the coldest place found within the Earth system, with an average temperature of about minus 85 degrees Celsius (minus 120 degrees Fahrenheit).
Where is the lowest layer of atmosphere?
The troposphere is the lowest layer of our atmosphere. Starting at ground level, it extends upward to about 10 km (6.2 miles or about 33,000 feet) above sea level. We humans live in the troposphere, and nearly all weather occurs in this lowest layer.
Which is the lowest layer of the atmosphere?
Located between about 80 and 700 kilometers (50 and 440 miles) above Earth’s surface is the thermosphere, whose lowest part contains the ionosphere. In this layer, temperatures increase with altitude due to the very low density of molecules found here. It is both cloud- and water vapor-free.
What is the layer of the atmosphere where gravity disappears?
The layer of the atmosphere in which gravity disappears is the exosphere. The atmosphere is the layer of gases that surrounds the Earth. It fulfills several functions, it contains the necessary oxygen for the life, protects of the solar rays and of external agents like meteorites…
Which is higher the stratosphere or the troposphere?
The troposphere is the layer that lies between the surface of the earth to a height of between 10 and 15 km. It is the only layer of the atmosphere that allows the development of life, and where the meteorological phenomena occur. The stratosphere is the layer that extends from 10-15 km in height to 40-45.
Is the Earth’s gravity strong enough to hold onto its atmosphere?
The Short Answer: Earth’s gravity is strong enough to hold onto its atmosphere and keep it from drifting into space. The answer in a word is… Fortunately for us, Earth’s gravity is strong enough to hold onto its atmosphere. Mars, for example, is less than half Earth’s size and around one-tenth Earth’s mass.
