Temperature and water vapor content in the troposphere decrease rapidly with altitude. Water vapor plays a major role in regulating air temperature because it absorbs solar energy and thermal radiation from the planet’s surface. The troposphere contains 99 % of the water vapor in the atmosphere.

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. When liquid or solid water particles grow large enough in size, they fall toward the earth as precipitation.

The water cycle also occurs in this layer of the atmosphere. The water cycle helps form clouds, which in form can help produce rain, sleet, snow and freezing rain. As you see, the troposphere is an important layer in Earth’s Atmosphere, as it is the layer that we live in and the layer that gives us weather.

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.

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.

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.

The troposphere is the lowest layer of the atmosphere with water vapor, vertical winds and temperatures that decrease as the altitude increases. An example of the troposphere is the layer below the tropopause. The weather, major wind systems, and cloud formations occur mostly in the troposphere.

In this page you can discover 12 synonyms, antonyms, idiomatic expressions, and related words for troposphere, like: exosphere mesosphere stratosphere thermosphere, atmosphere, mesosphere, lower-atmosphere, stratosphere, tropospheric, thermosphere, boundary layer, upper atmosphere, tropopause and water-vapor.

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.

The troposphere is the lowest layer of Earth’s atmosphere, and is also where nearly all weather conditions take place. It contains 75% of the atmosphere’s mass and 99% of the total mass of water vapour and aerosols.

: the lowest densest part of the earth’s atmosphere in which most weather changes occur and temperature generally decreases rapidly with altitude and which extends from the earth’s surface to the bottom of the stratosphere at about 7 miles (11 kilometers) high.

Most of the weather phenomena take place in this layer. The troposphere contains almost all the water vapor and most of the dust. This layer subject to intense mixing due to both horizontal and vertical mixing. Temperature decreases with height at an average rate of 10C per 167m of height above sea level.

Use the noun troposphere when you’re talking about the part of the atmosphere that’s closest to the surface of the Earth. The word troposphere comes from the Greek root tropos, “a turn or change.”

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.

Since the thickness of the troposphere is determined by the amount of solar energy and the vertical mixing, the tropopause is lower over areas where the air is cold than where it is warm.

The troposphere gets some of its heat directly from the Sun. Most, however, comes from Earth’s surface. The surface is heated by the Sun. Some of that heat radiates back into the air.

In a gas molecules have to scatter off molecules to exchange energy in larger distances, so the probability of transfer is much smaller. Air is a bad conductor because, to conduct heat current molecules should absorb heat and transmit it to neighbor by vibrating.

The layer of the atmosphere with the most air pressure in it is the troposphere. It is here that also most weather occurs. Air pressure decreases upwards.. In higher elevations, the atmosphere has lower pressure.

The Troposphere is the lowermost portion of Earth’s atmosphere. It is the densest layer of the atmosphere and contains approximately 75 percent of the mass of the atmosphere and almost all the water vapor and aerosol. The troposphere extends from the Earth’s surface up to the tropopause where the stratosphere begins.

inner core

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.)

Eventually (long after surface life had died), solar radiation would break atmospheric water into oxygen, which would react with carbon on the Earth to form carbon dioxide. The air would still be too thin to breathe. The lack of atmosphere would chill the Earth’s surface. Organisms that need air to breathe would die.

The troposphere is the only atmospheric layer that can support life. The higher layers have filtered out the harmful radiation, and there are large amounts of water vapor. This is the layer where clouds develop, birds fly, and pollution collects. Yes, the troposphere is where humans most pollute the atmosphere.

Troposphere is the densest layer of atmosphere that is composed of water vapour, dust particles and many other impurities. Due to this thickness, troposphere absorbs most of the heat radiated by the Earth’s surface, thereby, maintaining the temperature of the surface.

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. The chemical composition determines the air quality. Certain components, even if they are only present in small amounts, may harm health and vegetation.

Troposphere is considered as the most important layer of atmosphere. It is the lower most layer of the Atmosphere. Hence, Troposphere is very important for the existence of life on earth as it causes the cloud formation, raining and maintaining the heat balance of the earth.
