What Are 4 Facts About The Troposphere? - Fixanswer

The troposphere is

the lowest layer of the atmosphere, closest to the earth’s surface

. Its depth is different at different regions of the earth, being deeper in the warmer regions and shallower in the colder regions. The word ‘troposphere’ is derived from the Greek word ‘Tropos’ which means ‘change’.

What are the 4 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 are 4 facts about the atmosphere?

The atmosphere is made up of

78% nitrogen, 21% oxygen, and smaller amounts of argon, carbon dioxide, helium, and neon

. Contaminants in the atmosphere can include smoke, toxic gasses, dust, ash from volcanoes, and salt.

What are 4 facts about the stratosphere?

Stratosphere Facts and Stratosphere Definition. The stratosphere altitude is still high, though. …
Temperature Increases With Height. …
The Stratosphere Is Where Jets Like to Fly. …

What are 3 facts about the troposphere?

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 layer do planes fly in?

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 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.

Do we live in the troposphere?

We humans live in the troposphere

, and nearly all weather occurs in this lowest layer. Most clouds appear here, mainly because 99% of the water vapor in the atmosphere is found in the troposphere. Air pressure drops, and temperatures get colder, as you climb higher in the troposphere.

What does the troposphere do?

The troposphere contains about 85% of the atmosphere’s total mass. 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. The chemical composition determines the air quality.

Where is the troposphere the thickest?

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.

What are the major characteristics of troposphere?

It contains three-quarters of the mass of the Earth’s atmosphere and is composed of

78% nitrogen, 21% oxygen, and a 1% mixture of argon, water vapor, and carbon dioxide

. Air at the bottom of the troposphere or near the Earth’s surface is warmer, which means the higher the altitude, the colder it is.

What does the troposphere look like?

The troposphere is by far the

wettest

layer of the atmosphere; all of the layers above contain very little moisture. The bottom of the troposphere is at Earth’s surface. The troposphere extends upward to about 10 km (6.2 miles or about 33,000 feet) above sea level. … Air gets colder as one rises through the troposphere.

The troposphere lies closest to the Earth and is about 11 miles thick. This layer contains most of the air and oxygen in the atmosphere.

Our weather is formed in the

troposphere. Water evaporates from land to become rain or snow.
