1. The outermost shell of the atmosphere, between the mesosphere and outer space, where temperatures increase steadily with altitude. 2. The rocket had passed the stratosphere and mesosphere and was leaving the atmosphere.
What is a mesosphere in your own words?
The mesosphere is a layer of Earth’s atmosphere. The mesosphere is directly above the stratosphere and below the thermosphere. It extends from about 50 to 85 km (31 to 53 miles) above our planet. Temperature decreases with height throughout the mesosphere.
What is a good sentence for thermosphere?
2. The thermosphere interacts strongly with the sun and hence is greatly influenced by the sun’s solar activity, which occurs in cycles. 3. The shrinkage in the thermosphere, normally occurring during a solar minimum, has not recovered from the solar minimum of 2007-2009 but is in fact worse.
What happens in the mesosphere?
In the mesosphere, temperature decreases as altitude increases. This characteristic is used to define its limits: it begins at the top of the stratosphere (sometimes called the stratopause), and ends at the mesopause, which is the coldest part of Earth’s atmosphere with temperatures below −143 °C (−225 °F; 130 K).
What are 5 facts about the mesosphere?
The mesosphere is the coldest atmospheric layer surrounding the earth. It becomes cold enough to freeze water vapour in its atmosphere into ice clouds. These ice clouds are blue-white and are called noctilucent clouds or polar mesospheric clouds. These clouds are more visible at sunset from the earth’s poles.
Can you survive in the mesosphere?
The middle layer
The mesosphere lies between the thermosphere and the stratosphere. … The air is still thin, so you wouldn’t be able to breathe up in the mesosphere. But there is more gas in this layer than there is out in the thermosphere.
What is thermosphere short answer?
The thermosphere is a layer of Earth’s atmosphere. The thermosphere is directly above the mesosphere and below the exosphere. It extends from about 90 km (56 miles) to between 500 and 1,000 km (311 to 621 miles) above our planet. … Solar activity strongly influences temperature in the thermosphere.
What is the hottest layer of the atmosphere?
The thermosphere is often considered the “hot layer” because it contains the warmest temperatures in the atmosphere. Temperature increases with height until the estimated top of the thermosphere at 500 km. Temperatures can reach as high as 2000 K or 1727 ºC in this layer (Wallace and Hobbs 24).
What is the characteristics of thermosphere?
The thermosphere is very high above the Earth and is distinguished by an increase in temperature with altitude. The density of the air is extremely low, but the activity of the molecules are very high due to the amount of energy they are receiving from the sun.
What is an example of mesosphere?
Examples of mesosphere. The mesosphere is also the layer where most meteors burn up upon atmospheric entrance. The downwelling over the nightside causes adiabatic heating of the air, which forms a warm layer in the nightside mesosphere at the altitudes 90120 km.
What is the best definition of mesosphere?
: the part of the earth’s atmosphere between the stratosphere and the thermosphere in which temperature decreases with altitude to the atmosphere’s absolute minimum.
What are the characteristics of mesosphere?
The mesosphere:
- is directly above the stratosphere and below the thermosphere.
- extends from around 50-85 km above our planet (31-53 miles)
- possess temperatures that decrease with height throughout the mesosphere.
- contains strong zonal winds (east-west), atmospheric tides, planetary waves, and gravity waves.

What is ozone layer in a sentence?
a layer in the stratosphere (at approximately 20 miles) that contains a concentration of ozone sufficient to block most ultraviolet radiation from the sun. (1) The ozone layer surrounding the earth protects our skin from being hurt by the ultraviolet rays.
What is a sentence for precipitation?
Precipitation sentence example. The precipitation of rain, snow and hail is about 55 in. The precipitation is greatest on the Atlantic seaboard and in the elevated regions of the interior. About two-thirds of the total precipitation falls in the latter half of the year.
In which layer do we live?
We humans live in the troposphere, and nearly all weather occurs in this lowest layer.
Which is the coldest layer of atmosphere?
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).
What are the 7 layers of atmosphere?

What is the function of thermosphere?
This thermosphere greatly helps in protecting the Earth and making complete exploration of the space and making space communication possible.
What does the thermosphere contain?
The thermosphere contains mainly of oxygen, nitrogen and helium. It absorbs much of the ultraviolet and X-ray radiation. This thin density layer is where the International Space Station orbit the Earth.
Why can’t planes fly in the mesosphere?
In short we can say it is very cold,the air in the mesosphere is very thin and it is the highest layer and very far away from our planet hence it is very difficult to survive in this layer. We conclude that planes cannot fly in the mesosphere.
What is called the end of mesosphere?
The end of mesosphere is thermosphere .
What will happen if there is no mesosphere?
