what is the first layer of the atmosphere,and what lives there.

The troposphere is the lowest layer of Earth's atmosphere where we live, breathe, and experience almost all weather, like rain and clouds.

100

What is the stratosphere and where can you find it?

The stratosphere is the second layer of Earth's atmosphere, and it's located right above the layer we live in, the troposphere. It starts at about 6 to 12 miles above the ground and goes up to around 31 miles.

100

What is the mesosphere and where is it located?


  • The mesosphere is the third layer of Earth's atmosphere, found above the stratosphere and below the thermosphere. It's the layer where most meteors burn up.

What does the name "thermosphere" mean?

  1. The name "thermosphere" comes from the Greek word "thermos," which means "heat". It's called this because it's the layer of the atmosphere with very high temperatures.

What is the exosphere?

The exosphere is the very top and outermost layer of Earth's atmosphere. It's the part of the atmosphere that is the farthest away from Earth and is the final layer before space.

200

What can you find in the troposphere?

You can find the air we breathe, most of the clouds, wind, and other weather like rain and snow all in the troposphere.

200

What is special about the temperature in the stratosphere?

The stratosphere is special because it gets warmer as you go higher, which is the opposite of what happens in the lower layer of the atmosphere. The reason for this is that a special gas called ozone absorbs the sun's energy, which heats up the air.

200

Is it cold or hot in the mesosphere?

The mesosphere is the coldest layer of the atmosphere. Temperatures get colder as you go higher up, and can get as cold as -90°C (-130°F).

200

Where is the thermosphere located in Earth's atmosphere?

The thermosphere is located above the mesosphere and below the exosphere. It's the fourth layer from Earth's surface.

200

What is the exosphere like?

it's very, very thin! The air is so spread out in the exosphere that there are huge empty spaces between gas molecules, like hydrogen and helium. There's no air to breathe, and it's too sparse for things like airplanes or meteors to travel through.

300

Why is the troposphere important?

The troposphere is important because it's the layer where life exists, containing the breathable air and the weather we need for plants and animals to thrive.

300

What important layer is inside the stratosphere?

The very important ozone layer is found inside the stratosphere. This layer of ozone gas acts like a shield, protecting us from most of the sun's harmful ultraviolet (UV) rays.

300

Why can't we easily study the mesosphere?

It's too high for airplanes and weather balloons to reach, but too low for most satellites to orbit in. Scientists use special "sounding rockets" for short trips to gather information.

300

What makes the thermosphere so hot?

The thermosphere absorbs strong radiation from the sun, like UV and X-rays. This absorption of energy from the sun causes the temperatures in this layer to become extremely high.

300

How high up is the exosphere?

The exosphere is a huge layer that starts about 375 miles above the Earth's surface and goes up to about 6,200 miles away from Earth.

400

How does the temperature change in the troposphere?

As you go higher up into the troposphere, the temperature gets colder.

400

Are there clouds and weather in the stratosphere?

There is almost no weather in the stratosphere. All of the clouds and storms you see happen in the troposphere, the layer below it. Because there is very little water vapor in the stratosphere, clouds are a rare sight.

400

What is one important job the mesosphere does for us?

It protects us by acting like a protective shield. It burns up most of the meteors that enter Earth's atmosphere before they can hit the ground. 

400

Can you see anything in the thermosphere?


 Yes, you can see the Northern Lights (and Southern Lights)! They happen in the thermosphere when the solar radiation from the Sun makes particles in the air glow.

400

What is special about the exosphere?

t's the layer where many satellites, like the International Space Station, orbit the Earth. Because the gases are so spread out, satellites can zoom through it without much friction from air.

500

What is the thickness of the troposphere?

The troposphere is not the same thickness everywhere; it is about 8-9 miles (14 km) thick over the poles and about 10-12 miles (18-20 km) thick over the equator.

500

what event happens in this layer?

absorption of the sun's ultraviolet (UV) radiation by the ozone layer

500

which event happens in the mesosphere?

The mesosphere has two events: meteors burning up and the formation of noctilucent clouds. 

500

 What other things are found in the thermosphere besides gases?

Even though there are very few gases, the thermosphere is home to the International Space Station (ISS) and many other satellites that orbit Earth.

500

Does the exosphere have a hard edge?

No, there's no clear boundary at the top of the exosphere. It just gradually gets thinner and thinner, fading away into the vastness of outer space, like steam from a hot drink spreading into the air.
