How far up is the atmosphere?
It extends from Earth’s surface to an average height of about 12 km (7.5 mi; 39,000 ft), although this altitude varies from about 9 km (5.6 mi; 30,000 ft) at the geographic poles to 17 km (11 mi; 56,000 ft) at the Equator, with some variation due to weather..
How is the troposphere important for us?
From the tropopause all the way down to Earth’s surface, the troposphere is important because it is where weather occurs. … The troposphere provides oxygen that we can breathe, keeps Earth at a livable temperature, and allows for weather to occur, making it a very important part of the atmosphere.
What would happen without the troposphere?
The air would still be too thin to breathe. The lack of atmosphere would chill the Earth’s surface. We’re not talking absolute zero cold, but the temperature would drop below freezing. Water vapor from the oceans would act as a greenhouse gas, raising the temperature.
Is there weather in the 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.
Why is the troposphere important to life?
Importance of troposphere to life on earth The study of the troposphere is very important because we breathe the air in this layer of air. … Tropospheric processes, such as the water or hydrologic cycle (the formation of clouds and rain) and the greenhouse effect, have a great influence on meteorology and the climate.
What layer do planes fly?
stratosphereCommercial jet aircraft fly in the lower stratosphere to avoid the turbulence which is common in the troposphere below. The stratosphere is very dry; air there contains little water vapor. Because of this, few clouds are found in this layer; almost all clouds occur in the lower, more humid troposphere.
Is the troposphere stable?
2.1 Troposphere The troposphere is the lowest layer of the atmosphere, characterized by a temperature that decreases with altitude (Figure 20.1). … As a result, the troposphere is slightly stable to convection. Nevertheless, the adiabat provides a reasonable reference for the troposphere.
What are 3 facts about the troposphere?
The troposphere is made up of approximately 78% nitrogen, 21% oxygen, and 1% other gases, which include carbon dioxide, methane, neon, krypton, argon, helium, and hydrogen. The troposphere contains approximately 99% of the water vapour in the earth’s entire atmosphere.
In which part of atmosphere do we live?
The Troposphere This is the lowest part of the atmosphere – the part we live in.
Can planes fly in the mesosphere?
The mesosphere is above the stratosphere layer. The layer above the mesosphere is called the thermosphere. The mesosphere starts at 50 km (31 miles) above Earth’s surface and goes up to 85 km (53 miles) high. … Weather balloons and jet planes cannot fly high enough to reach the mesosphere.
What is the coldest layer?
mesosphereThe coldest layer of the atmosphere is known as the mesosphere. The mesosphere is the third layer up from the Earth’s surface right above the…
Is the Earth losing oxygen?
It sounds worse than it is: Earth’s atmosphere is steadily losing oxygen. But before you panic and gasp for breath, understand that oxygen levels have only dropped by 0.7 percent over the past 800,000 years.
What is the hottest layer of the earth?
inner coreAnswer and Explanation: The hottest layer of the Earth is its innermost layer, the inner core. Quite literally the center of the Earth, the inner core is solid and can get to…
Will the earth run out of oxygen?
Most of the breathable oxygen in Earth’s atmosphere is supplied by plant life in a process called photosynthesis . We’ll run out of it if we cut down too much of the world’s forests and kill too much plant life in the oceans. … As long as we sustain Earth’s plant life in sufficient quantity, we won’t run out of oxygen.
Do planes fly in the ozone layer?
Commercial aircraft routinely fly through the lower edges of the ozone layer. The systems that provide a breathable atmosphere for the passengers, includes a catalyst filter to destroy / reduce the amount of ozone in the air they pump into the cabin.
What is an interesting fact about the troposphere?
The troposphere is between 5 and 9 miles (8 and 14 kilometers) thick depending on where you are on Earth. It’s thinnest at the North and South Pole. This layer has the air we breathe and the clouds in the sky. The air is densest in this lowest layer.
What happens in troposphere?
The cycle, which occurs in the troposphere, begins as the sun evaporates large amounts of water from the earth’s surface and the moisture is transported to other regions by the wind. As air rises, expands, and cools, water vapor condenses and clouds develop.
