Class 11 Chapter 10 Water in the Atmosphere

What is the water in the atmosphere class 11th geography?

Water vapour present in the air is known as humidity. It is expressed quantitatively in different ways. The actual amount of the water vapour present in the atmosphere is known as the absolute humidity. It is the weight of water vapour per unit volume of air and is expressed in terms of grams per cubic metre.

What is the summary of water in the atmosphere?

Water at the Earth’s surface evaporates into water vapor, then rises up into the sky to become part of a cloud which will float off with the winds, eventually releasing water back to Earth as precipitation.

What are the three types of precipitation Class 11?

The most common types of precipitation are rain, hail, and snow. Rain is precipitation that falls to the surface of the Earth as water droplets.

What is dew class 11?

Dew is formed when the air has high relative humidity and the temperature of the air near the earth’s surface becomes very low. This causes condensation of water vapour into water droplets.

Why water is important in the atmosphere?

Water vapor is the most prevalent greenhouse gas. It causes roughly half of the warming of the planet. Like other greenhouse gases, it lets almost all of the sunlight reach the earth’s surface but absorbs heat radiated upward from the earth.

How does water leave the atmosphere?

In the cool air, water vapor is more likely to condense from a gas to a liquid to form cloud droplets. Cloud droplets can grow and produce precipitation (including rain, snow, sleet, freezing rain, and hail), which is the primary mechanism for transporting water from the atmosphere back to the Earth’s surface.

Water in the Atmosphere is a major part of our climate system. Water is present in our atmosphere in three forms gaseous, liquid, and solid. In the circulation process of water in the atmosphere, evaporation is really important. It is a process where water changes its form from liquid state to vapor and moves to the Earth’s surface into the atmosphere.

In this article, we are going to discuss the Water in the Atmosphere in detail.
