The troposphere begins at the Earth’s surface and extends from
4 to 12 miles (6 to 20 km) high
. The height of the troposphere varies from the equator to the poles. At the equator it is around 11-12 miles (18-20 km) high, at 50 °N and 50 °S , 51⁄2 miles and at the poles just under four miles high.
What is the height of troposphere?
The troposphere extends upward to
about 10 km (6.2 miles or about 33,000 feet) above sea level
. The height of the top of the troposphere varies with latitude (it is lowest over the poles and highest at the equator) and by season (it is lower in winter and higher in summer).
What is the average height of the troposphere Class 7?
Troposphere: This layer is the most important layer of the atmosphere. Its average height is
13 km
. The air we breathe exists here. Almost all the weather phenomena like rainfall, fog and hailstorm occur in this layer.
What is the average height of the troposphere in KM?
From the planetary surface of the Earth, the average height of the troposphere is 18 km (11 mi; 59,000 ft) in the tropics; 17 km (11 mi; 56,000 ft) in the middle latitudes; and 6 km (3.7 mi; 20,000 ft) in the high latitudes of the polar regions in winter; thus the average height of the troposphere is
13 km (8.1 mi;
…
At what height does the troposphere end?
The tropopause is a thermodynamic gradient-stratification layer, that marks the end of the troposphere, and lies
approximately 17 kilometres (11 mi) above the equatorial regions
, and approximately 9 kilometres (5.6 mi) above the polar regions.
How is troposphere important for us?
From the tropopause all the way down to Earth’s surface, the troposphere is important
because it is where weather occurs
. … The troposphere provides oxygen that we can breathe, keeps Earth at a livable temperature, and allows for weather to occur, making it a very important part of the atmosphere.
What is 7th water cycle?
(b) The water cycle is the
process by which water continually changes its form and circulates between oceans, atmosphere, and land
.
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 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.
How high up is the thermosphere?
Between about 53 miles (85 km) and 375 miles (600 km)
lies the thermosphere. This layer is known as the upper atmosphere. While still extremely thin, the gases of the thermosphere become increasingly denser as one descends toward the earth.
What is above the troposphere?
The stratosphere
starts just above the troposphere and extends to 50 kilometers (31 miles) high. The ozone layer, which absorbs and scatters the solar ultraviolet radiation, is in this layer. The thermosphere starts just above the mesosphere and extends to 600 kilometers (372 miles) high.
What is the coldest layer of the atmosphere?
Mesosphere
, coldest layer of Earth’s atmosphere.
Which is called tropopause limit?
The tropopause is traditionally defined by meteorologists as the lowest level at which the rate of decrease of temperature with respect to height (normally about 6 K km
− 1
in the troposphere)
decreases to 2 K km
− 1
, and the average from this level to any level within the next 2 km does not exceed 2 K km
− 1
.
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.
Why troposphere is the hottest part of the atmosphere?
That
layer absorbs the highest amount of solar energy making it
the hottest. The Troposphere- It is the lowest part of the atmosphere, the part where we live. … This layer contains most of the ozone gas present in the atmosphere.
