What are the conditions in the stratosphere?
The stratosphere is very dry; air there contains little water vapor. Because of this, few clouds are found in this layer; almost all clouds occur in the lower, more humid troposphere. Polar stratospheric clouds (PSCs) are the exception. PSCs appear in the lower stratosphere near the poles in winter.
What conditions allow for climate to happen inside of the troposphere?
The rising and sinking of air in the troposphere means that all of the planet’s weather takes place in the troposphere. Sometimes there is a temperature inversion, air temperature in the troposphere increases with altitude and warm air sits over cold air.
What are the major characteristics of troposphere?
The troposphere is by far the wettest layer of the atmosphere; all of the layers above contain very little moisture. The bottom of the troposphere is at Earth’s surface. The troposphere extends upward to about 10 km (6.2 miles or about 33,000 feet) above sea level.
What gases are in stratosphere?
Ozone, a form of oxygen with three atoms per molecule, is concentrated in the stratosphere. Ozone absorbs most of the ultraviolet (UV) radiation coming from the sun, preventing this radiation from reaching Earth’s surface.
What are the four characteristics of the troposphere?
What are the 4 characteristics of troposphere? 1 it is the first atmospheric layer closet to Earth’s surface. 2 the troposphere is the region where weather occurs. 3 the temperature of troposphere decreases with an increase in height. 4 the troposphere makes up approximately 75% of Earth’s atmosphere by mass.
Why does weather occur in the troposphere only?
Water vapour plays an important role in producing many weather systems and this water vapor is mostly confined to the lowest layer of the atmosphere called the troposphere. Hence all the weather phenomena occur in the troposphere only. How does the troposphere support life?
Is the troposphere the lowest layer of the atmosphere?
This diagram shows some of the features of the troposphere. The troposphere is the lowest layer of Earth’s atmosphere. Most of the mass (about 75-80%) of the atmosphere is in the troposphere. Most types of clouds are found in the troposphere, and almost all weather occurs within this layer.
Can you feel the Wind in the troposphere?
When you feel the wind on your face, see clouds in the sky, and watch a bird flap its wings in flight, you’re experiencing the troposphere. It’s a pretty nice layer to call home. Visit other layers in Earth’s atmosphere.
