Your question: Where is the troposphere thickest and where is it thinnest?

The troposphere is thickest at the equator, and much thinner at the North and South Poles. The majority of the mass of the entire atmosphere is contained in the troposphere—between approximately 75 and 80 percent.

Where is the troposphere the thinnest?

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.

Is the troposphere thick or thin?

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.

Which layer of the atmosphere is thinnest?

The Troposphere is the thinnest layer. Stratosphere- The stratosphere is the layer between the Troposphere and the Mesosphere.

Why is troposphere the densest layer?

Properties of the Troposphere

READ  What is the cheapest state to buy?

The troposphere is the shortest layer of the atmosphere. It rises to only about 12 kilometers (7 miles) above the surface. Even so, this layer holds 75% of all the gas molecules in the atmosphere. That’s because the air is densest in this layer.

Where is the troposphere the thickest?

The atmosphere is divided into five different layers, based on temperature. The layer closest to Earth’s surface is the troposphere, reaching from about seven and 15 kilometers (five to 10 miles) from the surface. The troposphere is thickest at the equator, and much thinner at the North and South Poles.

Do planes fly in the troposphere?

The atmosphere is divided up into five main layers but commercial aircraft fly in the bottom two layers — the troposphere, which sits closest to the surface, and the stratosphere, which sits just above it. As you climb up into the troposphere, the air pressure, temperature and air density all decrease.

What are 3 facts about the troposphere?

Fact Sheet

  • The troposphere contains 75% of the atmosphere’s total mass.
  • In either space or time the troposphere is not constant.
  • Weather occurs in the troposphere.
  • The troposphere is 10 miles from the equator.
  • The troposphere is 5-7 miles above the poles.
  • Does not contain ozone.

What is the hottest layer of the atmosphere?

The thermosphere is the hottest layer of the atmosphere.

Do we live in the troposphere?

The Troposphere

Is the exosphere the thinnest layer?

The air in the exosphere is extremely thin – in many ways it is almost the same as the airless void of outer space. The layer directly below the exosphere is the thermosphere; the boundary between the two is called the thermopause. The bottom of the exosphere is sometimes also referred to as the exobase.

Which is the coldest layer of the atmosphere?


What layer do we live in?


Is the troposphere hot or cold?

Troposphere. The temperature of the troposphere is highest near the surface of the Earth and decreases with altitude. On average, the temperature gradient of the troposphere is 6.5°C per 1,000 m (3.6°F per 1,000 ft.)

What are the 4 characteristics of troposphere?

Characteristics of troposphere

  • it is the first atmospheric layer closet to Earth’s surface.
  • the troposphere is the region where weather occurs.
  • the temperature of troposphere decreases with an increase in height.
  • the troposphere makes up approximately 75% of Earth’s atmosphere by mass.

What can we see in troposphere?

Nearly all of the water vapor and dust particles in the atmosphere are in the troposphere. That is why most clouds are found in this lowest layer, too. The bottom of the troposphere, right next to the surface of Earth, is called the “boundary layer”.
