Quick Answer: How Are Clouds Formed Class 9 Brainly?

What are the functions of water in our body Class 6?

Water is important for our body because of the following reasons: Water is a major constituent of all bodily fluids such as blood and plasma.

Water is essential for digestion of food, absorption of food and also excretion of wastes from the body.

Water is useful to cool the body and regulate temperature..

How are clouds formed in Short answer?

The Short Answer: Clouds are created when water vapor, an invisible gas, turns into liquid water droplets. These water droplets form on tiny particles, like dust, that are floating in the air.

How clouds are formed step by step?

Heated by sunshine, the ground heats the air just above it. That warmed air starts to rise because, when warm, it is lighter and less dense than the air around it. As it rises, its pressure and temperature drop causing water vapor to condense. Eventually, enough moisture will condense out of the air to form a cloud.

How are clouds formed Class 5?

Clouds are formed when warm air rises, expands and then cools. This cool air can’t hold as much water vapor as the warm air. The vapor will then begin to condense and form itself around dust particles that are floating in the air. When billions of these particles come together , they form a cloud.

What is water Vapour for Class 6?

Water vapour comes into the air from the evaporation of water present on the earth (in ponds, lakes, rivers and oceans, etc.) and from transpiration. It is water vapour present in air which rises high in the sky along with hot air, gets cooled, condenses to form clouds and then brings rain on the earth.

Why do clouds float?

The water rises, cools, and condenses. A cloud is formed! Clouds form when warm wet air rises and condenses in cold air. … The second reason that clouds can float in the air is that there is a constant flow of warm air rising to meet the cloud: the warm air pushes up on the cloud and keeps it afloat.

What are 3 things needed for clouds to form?

Students will discover that three main ingredients are needed for clouds to form: moisture, condensation, and temperature. 2. Evaporation and condensation are part of how a cloud forms.

What does a drought occur Class 6?

Answer: Drought occurs when it does not rain for many years.

How is rain caused Class 9?

Rain is formed by evaporation and condensation of water through water cycle. Acid rain is caused by the release of the gases like SO2 (sulphur dioxide) and NO2 (nitrogen dioxide) released from the emission of vehicles and combustion of fuels. These gases dissolve in rain water to form nitric acid and sulphuric acid.

What are clouds for Class 6?

Answer. a cloud is an comprising a visible mass of minute liquid droplets, frozen crystals or particles suspended in the atmosphere above the surface of a planetary body.

What are clouds Class 9?

Answer: Clouds are formed by an enormous collection of tiny droplets that are formed by the condensation of water vapours in the air. Water vapours are condensed when dust and other suspended particles of the air act as a nucleus for them. These particles condense the vapours into tiny water droplets.

How is soil formed class 9th?

Answer: Soil is formed by breaking down of rocks at or near the surface of the Earth through various physical, chemical, and biological processes by various factors such as the sun, water, wind, and living organisms. … These cracks lead to the breaking up of huge rocks into smaller pieces.

What causes clouds to form?

Clouds form when the invisible water vapor in the air condenses into visible water droplets or ice crystals. For this to happen, the parcel of air must be saturated, i.e. unable to hold all the water it contains in vapor form, so it starts to condense into a liquid or solid form.

Is fog a cloud?

Fog is a kind of cloud that touches the ground. Fog forms when the air near the ground cools enough to turn its water vapor into liquid water or ice. There are many different types of fog, too. Ice fog forms when the air near the ground is cold enough to turn the water in fog into ice crystals.

How are clouds formed short answer 6?

The process of evaporation followed by condensation causes the formation of clouds. … 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.

What is the composition of air class 6?

Answer: Air is a mixture of 79% nitrogen, 20% oxygen, 1% carbon dioxide, water vapours and some other gases. Air also contains dust particles.

What are the three main types of clouds?

Cumulus, Stratus, and Cirrus. There are three main cloud types.

Are clouds important?

Clouds are essential to the earth-atmosphere system. … Clouds help regulate Earth’s energy balance by reflecting and scattering solar radiation and by absorbing Earth’s infrared energy. Clouds are required for precipitation to occur and, hence are an essential part of the hydrologic cycle.

What is evaporation short answer Class 6?

The changing of a liquid into vapours or gas is called evaporation. Evaporation is used to obtain a solid substance that has dissolved in water or any other liquid. The dissolved substance is left as a solid residue when all the water has evaporated.

What causes wind class 9th?

Ans: The uneven heating of the earth’s surface is the main cause for the winds. On being heated more the air raises up and hence low pressure is created. Hence, the air in high pressure occupy the low-pressure region causing the wind.
