Earth’s atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases. These gases are found in layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere) defined by unique features such as temperature and pressure.
What 3 things are found in the troposphere?
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.
What are the 5 layers of the atmosphere and which layer do we live in?
The layers of the atmosphere from bottom to top are the troposphere, the stratosphere, the mesosphere, the thermosphere, and the exosphere. We live in the troposphere and most of our weather comes from this layer of the atmosphere.

Are clouds in the troposphere?
Clouds generally form within the troposphere, or the layer of atmosphere closest to the earth.
What layer do planes fly?
Commercial jet aircraft fly in the lower stratosphere to avoid the turbulence which is common in the troposphere below. The stratosphere is very dry air and contains little water vapor. Because of this, few clouds are found in this layer and almost all clouds occur in the lower, more humid troposphere.

- Exosphere. …
- The Edge of Outer Space.
What layer do we live in?
The Troposphere
This is the layer we live in and contains most of what we consider to be “the atmosphere,” including the air we breathe and nearly all of the weather and clouds we see. In the troposphere, the temperature of the air decreases the higher you go.
What can be found in the exosphere?
The exosphere layer is mainly composed of extremely low densities of hydrogen, helium and several heavier molecules including nitrogen, oxygen and carbon dioxide closer to the exobase.
Can planes fly in mesosphere?
Aeroplanes and other modern aircraft can’t fly above 50 kilometres because the lower air density at these altitudes doesn’t allow for sufficient lift. On the flip side, the air in the mesosphere is too dense for the safe passage of satellites and could damage them, so it is off limits for them too.
What is miso spear?
The mesosphere (/ˈmɛsoʊsfɪər/, from Greek mesos, “middle”) is the third layer of the atmosphere, directly above the stratosphere and directly below the thermosphere. In the mesosphere, temperature decreases as altitude increases.
What are some examples of atmosphere?
Atmosphere is defined as the area of air and gas enveloping objects in space, like stars and planets, or the air around any location. An example of atmosphere is the ozone and other layers which make up the Earth’s sky as we see it. An example of atmosphere is the air and gases contained inside a greenhouse.
What characteristic do scientists use to define four layers of Earth’s atmosphere?
Scientists divide Earth’s atmosphere into four main layers classified according to changes in temperature. These layers are the troposphere, the stratosphere, the mesosphere, and the thermosphere.
Can birds fly in the stratosphere?
The stratosphere contains roughly 20 percent of the atmosphere’s mass. Because bacterial life can survive in the stratosphere, this layer of the atmosphere belongs to the biosphere. Some species of birds have even been reported to fly in the lower levels of the stratosphere.
In what layer do weather balloons fly?
The Stratosphere: Ozone’s Home
The stratosphere is the next layer of the atmosphere. It extends anywhere from 4 to 12 miles (6 to 20 km) above Earth’s surface up to 31 miles (50 km). This is the layer where most commercial airliners fly and weather balloons travel to.
Do planes fly above the ozone layer?
Planes fly in the second layer of the atmosphere called the stratosphere. The stratosphere is the second layer of the atmosphere and the one where the ozone layer is formed and where the planes fly in.
What is this fog?
Fog shows up when water vapor, or water in its gaseous form, condenses. During condensation, molecules of water vapor combine to make tiny liquid water droplets that hang in the air. You can see fog because of these tiny water droplets. Water vapor, a gas, is invisible. Fog happens when it’s very, very humid.
What are nimbus clouds?
Nimbostratus clouds are dark, grey, featureless layers of cloud, thick enough to block out the Sun. Producing persistent rain, these clouds are often associated with frontal systems provided by mid-latitude cyclones. These are probably the least picturesque of all the main cloud types.
What are clouds for kids?
A cloud is made up of millions of tiny water droplets or ice crystals floating together in the air. The air always contains water vapor—water in the form of gas—which is invisible. The amount of water vapor that air can hold depends on the air’s temperature. The cooler the air, the less water it can hold.
What layer is the ozone in?
Most atmospheric ozone is concentrated in a layer in the stratosphere, about 9 to 18 miles (15 to 30 km) above the Earth’s surface (see the figure below). Ozone is a molecule that contains three oxygen atoms. At any given time, ozone molecules are constantly formed and destroyed in the stratosphere.
Which is the coldest layer?
The mesosphere is the middle layer of the atmosphere that has the coldest layer. … The layer contains most of the mass of the atmosphere. The mesosphere is the coldest atmospheric layer surrounding the earth.
Which layer is the Aurora found?
The thermosphere starts just above the mesosphere and extends to 600 kilometers (372 miles) high. Aurora and satellites occur in this layer.
How do you remember the 5 layers of the atmosphere?
The following mnemonic device may be useful to remember the earth’s atmospheric layers in order: The Silly Monkeys Twirled Endlessly (Troposphere, stratosphere, mesosphere, thermosphere, and exosphere). All of the choices are part of the earth’s atmospheric layers.
How many layers does the earth have?
The Earth is divided into three main layers. The dense, hot inner core (yellow), the molten outer core (orange), the mantle (red), and the thin crust (brown), which supports all life in the known universe. Earth’s interior is generally divided into three major layers: the crust, the mantle, and the core.
Which two layers contain 99% of the air in our atmosphere?
The lowest layer is known as the troposphere, which makes up approximately 75% of the total mass of the atmosphere and contains 99% of the atmosphere’s water. The troposphere extends up to approximately 11 kilometers (7 miles) from the surface and is the layer where atmospheric gases are most concentrated.
Can humans live in the exosphere?
Life in space
Space is very dangerous – and without protection, people would not be able to survive there. In space, there’s no air – so you couldn’t breathe. It’s cold – so you’d freeze.
Does it rain in the stratosphere?
No weather occurs in the stratosphere. The statosphere contains over 15% of the total mass of the atmosphere, and is where the ozone layer is located. … All weather stops at the top of the troposphere (called the tropopause), and the stratosphere is essentially cloud-free.
Can humans live in the stratosphere?
Similar to outer space, the stratosphere experiences freezing temperatures, with atmospheric pressures and oxygen levels far below the level required for human survival. Exposure to this environment causes unique injuries to the human body that can be deadly if the correct management is not promptly initiated.
Can you breathe in the exosphere?
The exosphere is the very edge of our atmosphere. … The exosphere has gases like hydrogen and helium, but they are very spread out. There is a lot of empty space in between. There is no air to breathe, and it’s very cold.
Can satellites be found in the exosphere?
Although the exosphere is technically part of Earth’s atmosphere, in many ways it is part of outer space. Many satellites, including the International Space Station (ISS), orbit within the exosphere or below.
Can you see Earth from the exosphere?
Upper boundary of Earth
The exosphere, observable from space as the geocorona, is seen to extend to at least 10,000 kilometres (6,200 mi) from Earth’s surface.
What happens if a plane goes too high?
If a passenger jet flies too high, it reaches a point called ‘Coffin Corner’. This is the point at which the aircraft’s low speed stall and high-speed buffet meet and the plane can no longer maintain its altitude which forces it to descend.
What can fly in the troposphere?
Helicopters and light aircraft typically fly in the troposphere. Light aircrafts are unable to operate at higher altitudes because they lack pressurized cabins. Therefore, they stay within a range of about 10,000 feet.
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!
What is thermosphere in geography?
The thermosphere is a layer of Earth’s atmosphere that 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.
Can you breathe in the mesosphere?
The mesosphere is 22 miles (35 kilometers) thick. 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 known as troposphere?
The troposphere is the lowest layer of Earth’s atmosphere. Most of the mass (about 75-80%) of the atmosphere is in the troposphere. Most types of clouds are found in the troposphere, and almost all weather occurs within this layer.
Is Clouds part of the atmosphere?
Clouds are technically part of both the atmosphere and the hydrosphere.
What things are part of the atmosphere?
We live at the bottom of an invisible ocean called the atmosphere, a layer of gases surrounding our planet. Nitrogen and oxygen account for 99 percent of the gases in dry air, with argon, carbon dioxide, helium, neon, and other gases making up minute portions. Water vapor and dust are also part of Earth’s atmosphere.
What is an example of atmosphere in a story?
Flaming candles, the ‘set’ of the skeletons dining, and so on all conjures a specific atmosphere. We’re usually going for spooky around Halloween, but in literature, atmosphere refers to the feeling, emotion, or mood a writer conveys to a reader through the description of setting and objects.
