What are 5 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 are the main characteristics of the troposphere and stratosphere?
Calm & stable layer In the troposphere, the vertical air always flows upwards due to the presence of convection currents. But in the stratosphere, there is temperature inversion so there is no or little flow of vertical air current upwards. This is the reason for the calmness of the stratosphere.
What is the main characteristic of the tropopause?
The transition zone separating the troposphere from the stratosphere is called the tropopause. The tropopause is characterized by temperatures that stop decreasing and remain steady, before later increasing in the stratosphere. Temperature is a measure of the average kinetic energy in a substance.
Is the troposphere hot or cold?
The troposphere, the lowest layer of Earth's atmosphere, is heated from below. The troposphere is warmest at the bottom near Earth's surface. The troposphere is coldest at its top, where it meets up with the layer above (the stratosphere) at a boundary region called the tropopause.
What is the importance of 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. All weather phenomena occurs here, like Wind belts, Precipitation, Cyclone etc which are the source for life on Earth.

What are the characteristics of thermosphere?
The thermosphere is the atmospheric region from ∼85 to ∼500 km altitude, containing the ionosphere. It is characterized by high temperature and large variability, in response to changes in solar ultraviolet radiation and solar-driven geomagnetic activity.
What is troposphere and its role?
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.
Why the troposphere is important?
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 troposphere contains about 85% of the atmosphere's total mass.
What occurs in the troposphere?
The lowest portion of the atmosphere is the troposphere, a layer where temperature generally decreases with height. This layer contains most of Earth's clouds and is the location where weather primarily occurs. The layers of Earth's atmosphere, with a yellow line showing the air temperature at various heights.
What are the main features of troposphere Class 7?
1. Troposphere: It is the lowest layer of the Earth's surface that extends to a height of 8 km at the poles and 18 km at the Equator. This layer is characterised with weather phenomenon like cloud formation, thunderstorms, rainfall and snowfall. Here, temperature decreases with the increase in height.
How does the troposphere protect life on Earth?
The atmosphere protects life on earth by shielding it from incoming ultraviolet (UV) radiation, keeping the planet warm through insulation, and preventing extremes between day and night temperatures.
What are the 4 characteristics of exosphere?
The exosphere is largely composed of light gases such as hydrogen, carbon dioxide, atomic oxygen, and helium. All of the gases described above are so light that they can escape the Earth's gravitational magnetic force and scatter freely across space.
Why troposphere is the most important layer?
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 troposphere contains about 85% of the atmosphere's total mass.
What is an important feature of troposphere Class 11?
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 are the main characteristics of the thermosphere?
The thermosphere is the atmospheric region from ∼85 to ∼500 km altitude, containing the ionosphere. It is characterized by high temperature and large variability, in response to changes in solar ultraviolet radiation and solar-driven geomagnetic activity.

What happens 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 is the troposphere made of?
The troposphere can be considered to be composed of dry air and water vapor. The main gases composing the dry air are nitrogen, oxygen, argon, and carbon dioxide.

What is the temperature in the troposphere?
As the density of the gases in this layer decrease with height, the air becomes thinner. Therefore, the temperature in the troposphere also decreases with height in response. As one climbs higher, the temperature drops from an average around 62°F (17°C) to -60°F (-51°C) at the tropopause.
Is troposphere hot or cold?
The troposphere, the lowest layer of Earth's atmosphere, is heated from below. The troposphere is warmest at the bottom near Earth's surface. The troposphere is coldest at its top, where it meets up with the layer above (the stratosphere) at a boundary region called the tropopause.
What is troposphere function?
