The mesosphere is a layer of the atmosphere that extends from the Earth’s surface to about 100,000 kilometers (62,000 miles) altitude. It is the region of the atmosphere that includes the lower atmosphere and the ionosphere. The mesosphere is a very thin layer and is not very conductive, so it is not very easy for electricity to flow through it. This means that the mesosphere is not very good at holding heat, which is why it is so hot on the Earth’s surface.
How hot is the mesosphere in the Earth?
The mesosphere is the layer of the Earth’s atmosphere that extends from the Earth’s surface to about 100,000 kilometers (62,000 miles) altitude.
Who protects us from asteroids?
Space agencies like NASA, the European Space Agency, and Russia’s Federal Space Agency are all working to protect humanity from asteroids.
How do spaceships not burn up?
A spaceship does not burn up when it touches the ground. The heat from the engine will cause the fuel to ignite, and the spaceship will fly off into the sky.
What protects the Earth from ultraviolet radiation?
The Earth’s atmosphere is the largest and most important part of the planet’s protective shield from ultraviolet radiation. The atmosphere contains about 93% of the Earth’s atmosphere and the Earth’s surface is about 93% of the Earth’s surface. The atmosphere is made up of about 1/3 of Earth’s atmosphere and the Earth’s surface is made up of about 7% of Earth’s atmosphere. The Earth’s atmosphere is made up of about 20% of the Earth’s water and the Earth’s surface is made up of about 80% of the Earth’s surface. The Earth’s atmosphere is a very thin layer that is about 1/6 of the Earth’s surface.
What protects us from meteors?
A. A sturdy roof.B. A good pair of shoes.C. A strong shield.D. Our eyes.
Does Earth’s atmosphere protect us from asteroids?
There is no clear answer to this question as it depends on the definition of “protection.” Some people believe that the atmosphere does not provide enough shielding against asteroids, while others believe that it does. There is no definitive answer, and it is still an open question for scientists.
Why meteors burn up in mesosphere?
The meteors that burn up in the mesosphere are created when the Earth’s atmosphere and outer layers of the Earth’s surface interact. This interaction creates a “gaseous” object that is about the size of a meteor and has a mass of about 1/3 of the Earth’s mass. When this object approaches the Earth’s surface, it starts to create a “solid” object by breaking up into pieces. These pieces then start to interact with the Earth’s atmosphere, creating a new “gaseous” object that is about the size of a meteor and has a mass of about 1/3 of the Earth’s mass.
Can planes fly in mesosphere?
No, planes cannot fly in the mesosphere.
How do meteorites get through the Earth’s atmosphere?
Meteorites get through the Earth’s atmosphere by breaking up into smaller pieces and falling to the ground.
What would NASA do if an asteroid?
NASA would study the asteroid and determine if it is a potential threat to Earth. If it is, then NASA would take appropriate action to protect Earth.
How does the mesosphere protect us?
The mesosphere is a layer of the Earth’s atmosphere that extends from the Earth’s surface to about 100 kilometers altitude. The mesosphere is home to the Earth’s most significant weather patterns, including the jet stream and the polar vortex. It is also a place where ozone depletion is a major concern. The mesosphere is also a place where the Earth’s atmosphere and lithosphere meet, which can lead to volcanic eruptions and earthquakes.
How do you survive an asteroid hitting Earth?
An asteroid that hits Earth would cause a lot of damage, but also kill a lot of people. The most likely outcome is that the asteroid would hit the Earth’s surface and create a crater, but it could also hit a city and cause a lot of damage.
What could possibly happen if the asteroid would hit the Earth?
One possibility is that the asteroid would cause a devastating impact that would leave a deep crater in the Earth’s surface. Another possibility is that the asteroid would cause a less severe impact, but would still cause significant damage.
What would happen if the moon was hit by an asteroid?
If the moon were hit by an asteroid, it would be destroyed.
Do meteorites burn up in Mars atmosphere?
There is no evidence that meteorites burn up in the Martian atmosphere.
Can a human survive in the mesosphere?
Yes, a human can survive in the mesosphere.
How can we protect the Earth?
There are many ways we can protect the Earth. One way is to reduce emissions from the Earth’s atmosphere. Another way is to improve our water resources. And another way is to reduce the use of energy.
What size asteroid would cause extinction?
There is no easy answer when it comes to answering this question as it depends on a variety of factors, including the size and shape of the asteroid, as well as the environment it is in. Some asteroids that could cause extinction are those that are very large and have a shape that makes them difficult for humans to see, such as the asteroid Vesta. Other asteroids that could cause extinction are those that are small and have a shape that makes them easy for humans to see, such as the asteroid Enceladus.
What will happen if there is no mesosphere?
If there is no mesosphere, the Earth’s atmosphere and outer layer would be completely destroyed, and the planet would be uninhabitable.
Why is the exosphere important to life on Earth?
The Earth’s atmosphere is a mix of oxygen and nitrogen. Nitrogen is the most abundant gas in the Earth’s atmosphere and it’s responsible for most of the Earth’s climate. When the Earth’s atmosphere is too thin, oxygen can escape from the Earth and it can create anoxic conditions. This can kill bacteria and other life forms and it can also cause the Earth to become a “blanket of darkness.” The Earth’s atmosphere is also important because it helps protect us from the sun. The Earth’s atmosphere is made up of about 78% nitrogen, 22% oxygen, and 0.3% argon.
How big was meteor that killed dinosaurs?
The meteor that killed dinosaurs was about the size of a small house.
What protects Earth from meteorites?
The Earth’s atmosphere, surface, and ocean are all protectors of the planet from meteorites. The Earth’s atmosphere scatter incoming meteors so that they don’t hit the ground, the surface has a high enough temperature so that the meteor doesn’t vaporize (turn into a rock), and the ocean has a high enough salt content that the meteor doesn’t freeze.
What would happen if a 6 mile wide asteroid hit Earth?
If a large asteroid were to hit Earth, it would cause a lot of damage and casualties. The asteroid would be so large that it would be difficult to remove, and it would create a huge crater on the ground.
What is the main function of the mesosphere?
The mesosphere is the lower atmosphere and outer layer of the Earth’s atmosphere. It is located near the Earth’s equator and contains the most air.
When did an asteroid last hit Earth?
The last time an asteroid hit Earth was about 4.6 billion years ago.

What is the mesosphere made of in the Earth?
The mesosphere is made up of the lower atmosphere, the upper atmosphere, and the outer space.
