What are some facts about the layers of the atmosphere?
- There are five layers within the atmosphere.
- The troposphere lies closest to the Earth and is about 11 miles thick.
- The stratosphere lies above the troposphere and goes up about 30 miles high.
- The mesosphere is the next layer, reaching 50 miles from the Earth.

What does the mesosphere protect us from?
The mesosphere protects the Earth from cosmic debris such as meteors. Sea level rise, extreme weather events, and other effects of climate change all post risks to human health, critical infrastructure, agriculture, and the ecosystems that support us. When the sun’s UV …
What gases can be found in the mesosphere?
The percentage of oxygen, nitrogen, and carbon dioxide in the air in the mesosphere is essentially the same as that in the levels of the Earth's atmosphere immediately above the Earth's surface.
What is mesosphere known for?
The mesosphere lies between the thermosphere and the stratosphere. “Meso” means middle, and this is the highest layer of the atmosphere in which the gases are all mixed up rather than being layered by their mass.
What can be found in the thermosphere?
In the upper thermosphere, atomic oxygen (O), atomic nitrogen (N), and helium (He) are the main components of air. Much of the X-ray and UV radiation from the Sun is absorbed in the thermosphere. When the Sun is very active and emits more high-energy radiation, the thermosphere gets hotter and expands or "puffs up".
What are 3 facts about the mesosphere?
The mesosphere is the third and coldest layer of Earth's atmosphere, reaching about 130 degrees below zero. The mesosphere is also where most meteors, or space rocks and metal, burn up before they can crash to the ground. It's like a superhero's force field that protects the Earth!
Can you breathe in the mesosphere?
As a result, air pressure is very low. A person traveling through the mesosphere would experience severe burns from ultraviolet light since the ozone layer which provides UV protection is in the stratosphere below them. And there would be almost no oxygen for breathing!
Can 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. Note: Remember also the plane can't fly in the thermosphere.
What is found in the stratosphere?
The stratosphere is where you'll find the very important ozone layer. The ozone layer helps protect us from ultraviolet radiation (UV) from the sun. In fact, the ozone layer absorbs most of the UV radiation the sun sends to us. Life as we know it wouldn't be possible without this layer of protection.
What can be found in the troposphere?
The air is densest in this lowest layer. In fact, the troposphere contains three-quarters of the mass of the entire atmosphere. The air here is 78% nitrogen and 21% oxygen. The last 1% is made of argon, water vapor, and carbon dioxide.
Why mesosphere is the coldest layer?
Due to the lack of solar heating and very strong radiative cooling from carbon dioxide, the mesosphere is the coldest region on Earth with temperatures as low as -100 °C (-148 °F or 173 K).
Is the mesosphere hot or cold?
The mesosphere lies above the stratosphere and extends to an altitude of about 85 km (Ahrens 13). This is layer is often referred to as the cold layer, as the lowest readings in the atmosphere are found here. Temperature decreases with height, reaching a minimum average value of -90 ºC at the top of the layer.
Is the mesosphere blue?
The mesosphere has red sprites, blue jets, and two types of clouds. Noctilucent clouds are the highest clouds in the atmosphere.
Is mesosphere the coldest layer?
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).
Why is mesosphere the coldest layer?
The mesosphere is the coldest layer because it has essentially nothing to heat it. The atmosphere is primarily heated from below, and the troposphere is warmed by that mechanism. The stratosphere is colder, but ozone in the upper stratosphere absorbs enough radiation to warm it.
Can a human survive in the mesosphere?
The mesosphere has a very low density of gas molecules. Temperature decreases in the mesosphere with altitude because the heat source is the stratosphere. The mesosphere is no place for human life!
Is mesosphere the coldest layer?
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 is the hottest layer of atmosphere?
The thermosphereThe 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).
Why is the mesosphere cold?
The mesosphere decreases in temperature with altitude. The mesosphere ranges in temperatures from -2.5 to -90 degrees Celsius. The reason the tempe...
What does the mesosphere contain?
The mesosphere has the same composition as the other layers of Earth's atmosphere. The composition of the atmosphere is generally 78% nitrogen (N),...
What are the main characteristics of the mesosphere?
The main characteristics of the mesosphere that differentiate it from other layers of Earth's atmosphere are the following: The mesosphere is the...
What is the mesosphere?
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. The coldest temperatures in Earth's atmosphere, about -90° C (-130° F), ...
Why is the mesosphere so mysterious?
Since it is difficult to take measurements of the mesosphere directly using instruments, much about the mesosphere is still mysterious. Most meteors vaporize in the mesosphere. Some material from meteors lingers in the mesosphere, causing this layer to have a relatively high concentration of iron and other metal atoms.
How do waves and tides affect the mesosphere?
These waves and tides carry energy from the troposphere and the stratosphere upward into the mesosphere, driving most of its global circulation .
What is the coldest layer of the atmosphere?
The coldest temperatures in Earth's atmosphere, about -90° C (-130° F), are found near the top of this layer. The boundary between the mesosphere and the thermosphere above it is called the mesopause. At the bottom of the mesosphere is the stratopause, the boundary between the mesosphere and the stratosphere below.
Which layer of the atmosphere is drier than the troposphere?
These peculiar clouds form much, much higher up than other types of clouds. The mesosphere , like the stratosphere below it, is much drier than the moist troposphere we live in; making the formation of clouds in this layer a bit of a surprise.
Is the mesosphere difficult to study?
The mesosphere is difficult to study, so less is known about this layer of the atmosphere than other layers. Weather balloons and other aircraft cannot fly high enough to reach the mesosphere. Satellites orbit above the mesosphere and cannot directly measure traits of this layer.
What is the Mesosphere?
The Earth's atmosphere can be broken up into layers based on varying densities, temperatures, and atmospheric phenomenon that occur within them. From the outermost layer to the surface of Earth, the layers of the atmosphere are as follows:
Mesosphere Characteristics
This lesson will focus entirely on the third and middle layer of the atmosphere: the mesosphere. The word mesosphere comes from the Greek word mesos, which means middle. But what is the mesosphere? Exactly where is the mesosphere located? And what makes it different from the other layers?
Meteorology in the Mesosphere
Besides the ionization and burning up of shooting stars or meteors within the Earth's mesosphere, there are other meteorological or atmospheric phenomena that also occur that make the mesosphere distinct from other layers of the atmosphere.
