The study of the troposphere is very important because we breathe the air in this layer of air. … 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.
What is the significance 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 would happen if there was no troposphere?
The lack of atmosphere would chill the Earth’s surface. We’re not talking absolute zero cold, but the temperature would drop below freezing. Water vapor from the oceans would act as a greenhouse gas, raising the temperature.
Why is troposphere considered as the most important part of the atmosphere?
The troposphere is the sphere that is more essential type of the life-supporting layer in the earth and is thus is the most essential and most important for the life as it is the theater for the storms and all sort of the weather events and all sort of the element of the weather occur here and all the dust and water …
Which layer of the atmosphere is most important and why?
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.
Why is the thermosphere important to life on earth?
It keeps the planet warm and protects us from the harmful radiation of the Sun. It also ensures a healthy balance between oxygen and carbon dioxide so that life can be sustained on the planet.
Why does tropopause height vary?
The height of the tropopause varies with latitude, season of the year, and the weather conditions. … As the temperature decreases with height, so the temperature at the tropopause over the poles will be higher than over the equator because the tropopause is closer to the ground here.
How does the troposphere affect life on earth?
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.
What happens in the tropopause?
The troposphere is the region where nearly all water vapour exists and essentially all weather occurs. …of the troposphere, called the tropopause, corresponds to the level in which the pattern of decreasing temperature with height ceases. It is replaced by a layer that is essentially isothermal (of equal temperature).
Why is tropopause colder at equator?
This site says that the tropopause is at a higher altitude at the equator because: Gravitational force from a point is higher closer to it and reduces with increasing distance from it. Because the Earth itself is broader at equator, the equator experiences less gravity allowing air to reach bigger heights.
What is the difference between the troposphere and the tropopause?
The troposphere is the lowest and thickest layer of the atmosphere. … The tropopause is the boundary layer between the troposphere and the stratosphere . The thickness of the troposphere depends upon a number of atmospheric variables at latitude .
What is the significance of ozone in the atmosphere?
Ozone protects the Earth from harmful ultraviolet (UV) rays from the Sun. Without the Ozone layer in the atmosphere, life on Earth would be very difficult. Plants cannot live and grow in heavy ultraviolet radiation, nor can the planktons that serve as food for most of the ocean life.
What is the main characteristic of 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.
Why is the tropopause higher in the summer?
Deep convection (thunderstorms) in the Intertropical Convergence Zone, or over mid-latitude continents in summer, continuously push the tropopause upwards and as such deepen the troposphere. This is because thunderstorms mix the tropospheric air at a moist adiabatic lapse rate.
How does the presence of the tropopause affect weather systems in the troposphere?
The pattern of warming and cooling also affects the zonal wind structure in the region of the subtropical upper troposphere and lower stratosphere (UTLS). This is related to the height structure of the tropopause. … Climate change related increases in UTLS winds increase the speed of the waves.
Why do clouds stop at the tropopause?
Surface air is warmed by the Sun-heated ground surface and rises; if sufficient atmospheric moisture is present, water droplets will condense as the air mass encounters cooler air at higher altitudes. … The tropopause halts further upward motion of the cloud mass.
How does convection affect the atmosphere?
How does convection affect the weather? Convection within the atmosphere can often be observed in our weather. … Stronger convection can result in much larger clouds developing as the air rises higher before it is cooled, sometimes producing Cumulonimbus clouds and even thunderstorms.
What is the ozone layer and why is it important?
The ozone layer in the stratosphere absorbs a portion of the radiation from the sun, preventing it from reaching the planet’s surface. Most importantly, it absorbs the portion of UV light called UVB. UVB is a kind of ultraviolet light from the sun (and sun lamps) that has several harmful effects.
Why is thermosphere important in communication?
The ionosphere layer is a layer that contains the charged ions, and it has an important role in wireless communications and broadcasting as it reflects the radio waves that transmitted by the radio stations and the communication centres.
Why is carbon dioxide a necessary part of the atmosphere?
Carbon dioxide is an important greenhouse gas that helps to trap heat in our atmosphere. Without it, our planet would be inhospitably cold. … Respiration, the process by which organisms liberate energy from food, emits carbon dioxide. When you exhale, it is carbon dioxide (amongst other gases) that you breathe out.
Which layer is the the most important one and why?
The temperature of the troposphere decreases with an increase in height.it is very close to the earth’s surface . that’s why it is called the most important layer of the atmosphere…. hope this helps you !
Which layer of the atmosphere is most important for us and why Class 7?
Answer: Troposphere is the most important layer: As all weather phenomena like the formation of clouds, fog, mist, dew, thunder, lightening, precipitation etc. occur in this layer. This layer protects us from the excessive heat of the sun during the day and keeps the earth’s surface warm at night.
What is the lower most layer of atmosphere explain its importance?
The Troposphere
This is the lowest part of the atmosphere – the part we live in. It contains most of our weather – clouds, rain, snow. In this part of the atmosphere the temperature gets colder as the distance above the earth increases, by about 6.5°C per kilometre.
