why do most clouds form in the troposphere

Water present on the earth’s surface gets evaporated due to sunlight, and then rises up in the atmosphere. On reaching a certain height, water vapour present in air condenses to form tiny droplets of water. These water droplets collect to form clouds that float in air.

How are clouds formed Class 9?

How are clouds formed? Ans. During day time water from different sources like pond, lake, river, sea, well etc get evaporated and this water vapour rises up with the hot air. At a particular height the air cools and the water vapour condenses to form minute droplets and form clouds.

Why troposphere is the most important layer of the atmosphere Class 7?

Troposphere is the densest layer of atmosphere that is composed of water vapour, dust particles and many other impurities. Due to this thickness, troposphere absorbs most of the heat radiated by the Earth’s surface, thereby, maintaining the temperature of the surface.

What are the most important factors of the troposphere and stratosphere?

The troposphere is heated from the ground, so temperature decreases with altitude. Because warm air rises and cool air sinks, the troposphere is unstable. In the stratosphere, temperature increases with altitude. The stratosphere contains the ozone layer, which protects the planet from the Sun’s harmful UV radiation.

What makes the troposphere special among the five layers of the atmosphere?

This layer has the air we breathe and the clouds in the sky. The air is densest in this lowest layer. In fact, the troposphere contains three-quarters of the mass of the entire atmosphere.

Why is troposphere the most important of all layers of the atmosphere Class 11?

It is most important layer of the atmosphere because: Thickness of the troposphere is greatest at the equator because heat is transported to great heights by strong convectional currents. This layer contains dust particles and water vapour. All changes in climate and weather take place in this layer.

What is the importance of the ozone layer found on the boundary of the troposphere and stratosphere?

The stratosphere extends from the top of the troposphere to about 50 km (31 miles) above the ground. The infamous ozone layer is found within the stratosphere. Ozone molecules in this layer absorb high-energy ultraviolet (UV) light from the Sun, converting the UV energy into heat.

Why does water circulate in the troposphere?

The uneven heating of the regions of the troposphere by the sun ( the sun warms the air at the equator more than the air at the poles )causes convection currents, large-scale patterns of winds that move heat and moisture around the globe.

Why is the troposphere less at the poles?

Its average height is 36 090 ft (11 km) at about 45° latitude. Since the thickness of the troposphere is determined by the amount of solar energy and the vertical mixing, the tropopause is lower over areas where the air is cold than where it is warm.

What weather phenomena is found in the troposphere?

The troposphere (from Greek: tropein – to change, circulate or mix) is the lowermost layer of the Earth’s atmosphere. Most of the weather phenomena, systems, convection, turbulence and clouds occur in this layer, although some may extend into the lower portion of the stratosphere.
