What are two main things that are unique to the troposphere?

The troposphere provides several important benefits: it holds nearly all of the water vapor in the Earth’s atmosphere, regulates temperature and produces weather. The troposphere forms the lowest level of the Earth’s atmosphere, extending down to the surface of the Earth.

What is one fact 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.

What’s so important about the troposphere?

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 is an interesting fact about the troposphere?

The troposphere contains approximately 99% of the water vapour in the earth’s entire atmosphere. Despite the fact that only a small percentage of the troposphere’s gas is carbon dioxide, this is the determining factor in whether the earth is warm or whether it experiences an ice age.

How thick is the troposphere?

4 to 12 miles
The troposphere is the layer closest to Earth’s surface. It is 4 to 12 miles (7 to 20 km) thick and contains half of Earth’s atmosphere. Air is warmer near the ground and gets colder higher up.

How hot is the troposphere?

The global average temperature at the surface is 59 degrees F (15 degrees C) but decreases to around minus 82 degrees F (minus 63 degrees C) at the top of the troposphere. On the basis of mean tropospheric depth, the average rate of temperature decrease is 3.6 degrees F per 1,000 ft.

What is interesting about 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.

What are some interesting facts about the stratosphere?

Interesting Stratosphere Facts. – The stratosphere occupies the central region of the atmosphere, and is the second layer from the ground; tropopause separates the stratosphere from the troposphere. The stratosphere constitutes about 24% of the total atmosphere. And it contains about 19% of the total atmospheric gases.

What are 3 facts about the stratosphere of the atmosphere?

Facts About The Stratosphere The stratosphere is the second layer of the atmosphere (above the troposphere.) It extends from a height of approximately 10 km (6 miles) to 50 km (30 miles) above the Earth’s surface. It borders the troposphere below through a thin transitional space called the tropopause.

What are some things in the stratosphere?

The stratosphere has two major features that contribute to the state of Earth’s surface. The first is most well known–the stratosphere contains high concentrations of ozone which shields the ground from many high energy photons that would otherwise contribute to plant damage and skin cancer.

What happens in the troposphere?

The troposphere (from Greek: tropein – to change, circulate or mix) is the lowermost layer of the Earth’s atmosphere. Most of the weather phenomena, systems, convection, turbulence and clouds occur in this layer, although some may extend into the lower portion of the stratosphere.
