What happens to all the water in the air?
The atmosphere is the superhighway in the sky that moves water everywhere over the Earth. Water at the Earth’s surface evaporates into water vapor which 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.
Can we see water vapor in the air?
Gaseous water, or water vapor, isn’t something you can see, but it’s part of the air around you. Under normal circumstances, water vapor enters the atmosphere through evaporation and leaves by condensation (rain, snow, etc.). Water vapor also enters the atmosphere by a process called sublimation.
What is the amount of water vapor in the air?
The amount of water vapor in the air is called absolute humidity. The amount of water vapor in the air as compared with the amount of water that the air could hold is called relative humidity.
Does all air contain water?
Air, even “clear air,” contains water molecules. Clouds exist in the atmosphere because of rising air. A common myth is that clouds form because cooler air can hold less water than warmer air—but this is not true.
Is air inside the water?
Water is denser medium then air, so the rays of light goes away from the normal which can also be considered as divergent which is similar to diverging lens. It can be seen in figure below, So, from this we can say that an air bubble inside the water behaves as a diverging or concave lens.
Do you think air is present in the water give its function?
Answer: yes air is present in water. Explanation: air is present in water in diffused state, this air is required to breathing of aqautic animals like fishes.
What are the 5 uses of air?
Important Uses of Air
- Sustain life and growth.
- Combustion.
- Maintaining Temperature.
- Supplier of Energy.
- Photosynthesis.
How do you know that air is around you?
Air is present all around us. We cannot see the air around us but we can feel its presence when the leaves rustle or branches sway.
How do you feel the presence of air?
To feel the presence of air do the following things:

- Blow air by your note book. You can feel its presence.
- 3.BY making paper kite and trying to fly it.
- Riding the bicycle on windy day.
How does air feel around us?
Since air is invisible we easily forget that it is all around us. When we blow air in a balloon, we can feel the air pushing on the balloon. It’s the same with a tire or basketball. When we sit in front of a fan, we can actually feel the air molecules moving in the same direction.
What is the important of air and water in our daily life?
Air is important because it helps water move between these states in a process scientists call the water cycle. Heated by the sun, surface water evaporates into the air and becomes water vapor.
How does air help us in daily life?
Air is important for the breathing of all living things on Earth. It provides oxidation processes that supply the body with the necessary energy. It is a significant supplier of energy: all living plants and animals depend on oxygen to generate valuable energy.
Why do we need to breathe in air?
Everyday functions of the body like digesting your food, moving your muscles or even just thinking, need oxygen. When these processes happen, a gas called carbon dioxide is produced as a waste product. The job of your lungs is to provide your body with oxygen and to get rid of the waste gas, carbon dioxide.
Why is atmosphere important for us Class 6?
The atmosphere is essential for life for the following reasons: (a) Oxygen, which is essential for the survival of all living organisms, is present in the atmosphere. (b) Essential gases that support life on the earth are present in the atmosphere. (c) Water cycle would not have been possible without the atmosphere.
How is atmosphere important to us for Class 7?
The atmosphere contains the air that we breathe; protects us from the harmful radiation of the Sun; helps to keep the planet’s heat on the surface, and plays a very important role in the water cycle. Plants require carbon dioxide for photosynthesis; they use sunlight to change carbon dioxide and water into food.
What is carbon dioxide for Class 6?
Carbon Dioxide: Carbon dioxide is a gas produced during respiration. It is also produced on burning of organic substances. It is used by plants for photosynthesis. Composition of Air: Air is a mixture of nitrogen, oxygen, carbon dioxide, water vapour and a few other gases.
