- The troposphere is the lowermost portion of Earth's atmosphere and the one in which most weather phenomena occur; this layer extends to an altitude of 7-17 km, depending on latitude. Generally, jets fly near the top of this layer. The troposphere is directly below the stratosphere. The word troposphere stems from the Greek tropos for turning or mixing. This region, constantly in motion, is the densest layer. Nitrogen and oxygen are the primary gases, within this region. The tropopause marks the limit of the troposphere and the beginning of the stratosphere. The temperature above the tropopause increases slowly with height up to about 50 km. In telecommunication, the term troposphere has the following meanings: 1. The lower layers of atmosphere, in which the change of temperature with height is relatively large.

The Troposphere The troposphere starts at Earth's surface and goes up to a height of 7 to 20 km (4 to 12 miles, or 23,000 to 65,000 feet) above sea level. Most of the mass (about 75-80%) of the atmosphere is in the troposphere. Almost all weather occurs within this layer.

- The thermosphere is the layer of Earth's atmosphere that still contains substantial molecules of heavier gases. It occurs below the outermost layer, the exosphere, which consists mainly of a near-vacuum of hydrogen and helium. The definition of thermosphere is the atmosphere layer between the mesophere and the exosphere The thermoshpere is the biggest of all the layers of the Earth's atmospher … edirecly above the mesosphere and directly below the exoshpere. 2 people found this useful.

troposphere tro·po·sphere. The lowest region of the atmosphere, bounded by the Earth's surface and the tropopause and characterized by temperatures that decrease with increasing altitude. Weather and most cloud formations occur in the troposphere.he lower layers of atmosphere, in which the change of temperature with height is relatively large. It is the region where clouds form, convection is active, and mixing is continuous and more or less complete. See also atmosphere.

- The troposphere is the lowest layer of the atmosphere; it begins at the surface and extends to between 7 km (23,000 ft) at the poles and 17 km (60,000 ft) at the equator, with some variation due to weather factors. The troposphere has a great deal of vertical mixing due to solar heating at the surface.

The Stratosphere The Stratosphere. The stratosphere is a layer of Earth's atmosphere. The stratosphere is the second layer, as one moves upward from Earth's surface, of the atmosphere. The stratosphere is above the troposphere and below the mesosphere. The top of the stratosphere occurs at 50 km (31 miles) altitude. The boundary between the stratosphere and the mesosphere above is called the stratopause.

- The troposphere is the lowest part of the atmosphere of the Earth. It is shallower near the polar regions and is denser in the tropics. Observable day-to-day weather phenomeno…n occur here. The temperature of the troposphere decreases with increase in height and hence water vapour content decreases with height. An imaginary line at the boundary of the troposphere and the stratosphere is known as tropopause. The troposphere constitutes 80% of the total mass of the atmosphere and almost all of the water vapour and atmospheric particulate matter are concentrated in this layer.

- - Layers of the earth's atmosphere. TROPOSPHERE. The troposphere is the portion of the Earth's atmosphere that extends from the surface of the Earth to a height of about 3.7 miles (6 km) at the North Pole or the South Pole and 11.2 miles (18 km) at the equator.

- Here, living things are also free from the radiation showers which flow down through most of the earth's atmosphere. Compared to the rest of the atmosphere, the troposphere is a tiny layer, extending at most ten miles (16km) up from the earth's surface. Within this small layer almost all of our weather is created—the short term changes in temperature, wind, pressure, and moisture that we experience as part of our daily lives.

- The troposphere is the lowest layer of the atmosphere. This is the layer where most weather takes place. Most thunderstorms don't go much above the top of the troposphere (about 10 km) . In this layer, pressure and density rapidly decrease with height, and temperature generally decreases with height at a constant rate.

Atmosphere of Earth The troposphere is the lowest layer of Earth's atmosphere. It extends from Earth's surface to an average height of about 12 km, although this altitude actually varies from about 9 km (30,000 ft) at the poles to 17 km (56,000 ft) at the equator, with some variation due to weather.

- The troposphere is the layer where most of the world's weather takes place. Since temperature decreases with altitude in the troposphere, warm air near the surface of the Earth can readily rise, being less dense than the colder air above it. In fact air molecules can travel to the top of the troposphere and back down again in a just a few days. Such vertical movement or convection of air generates clouds and ultimately rain from the moisture within the air, and gives rise to much of the weather which we experience.

What Is the Importance of the Troposphere? Quick Answer. 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.

Stratosphere The stratosphere (/ˈstrætəˌsfɪər, -toʊ-/[3][4]) is the second major layer of Earth's atmosphere, just above the troposphere, and below the mesosphere. About 20% of the atmosphere's mass is contained in the stratosphere. The stratosphere is stratified in temperature, with warmer layers higher and cooler layers closer to the Earth. The increase of temperature with altitude is a result of the absorption of the Sun's ultraviolet radiation by the ozone layer. This is in contrast to the troposphere, near the Earth's surface, where temperature decreases with altitude.

- The troposphere is the lowest portion of Earth's atmosphere. It contains approximately 75% of the atmosphere 's mass and 99% of its water vapor and aerosols.The average depth of the troposphere is approximately 17 km (11 mi) in the middle latitudes.he tropopause is the boundary region between the troposphere and the stratosphere. Measuring the temperature change with height through the troposphere and the stratosphere identifies the location of the tropopause.

Troposphere: Definition, Facts, Temperature & Characteristics Gasses in the Troposphere. Earth's atmosphere is made up of gas molecules that are packed close together near the surface and thin out more and more until about 300 miles above Earth's surface. This is due to gravity.

Tropospheric ozone Ozone (O 3) is a constituent of the troposphere (it is also an important constituent of some regions of the stratosphere commonly known as the ozone layer).The troposphere extends from the Earth 's surface to between 12 and 20 kilometers above sea level and consists of many layers.Ozone is more concentrated above the mixing layer, or ground layer. Ground-level ozone, though less concentrated than ozone aloft, is more of a problem because of its health effects.Photochemical and chemical reactions involving it drive many of the chemical processes that occur in the atmosphere by day and by night.zone (O 3) is a constituent of the troposphere (it is also an important constituent of some regions of the stratosphere commonly known as the ozone layer).
