Chapter-5 Water

Explanation:

Water turns to vapour when exposed to the sun's radiation. When this air cools, it condenses into clouds. This could then precipitate as rain, snow, or ice on Earth's surface. Precipitation is the term used to describe the act of water returning to the earth's surface as rain, snow, or ice.

Explanation:

The water cycle is the process by which water continuously transforms its shape and moves between oceans, the atmosphere, and land.

Explanation:

precipitation is the word used to describe the falling of moisture in the form of rain, snow, fog, sleet, and hail.

Explanation:

The movement of water between oceans, the atmosphere, and the land occurs through a mechanism known as the water cycle.

Explanation:

The factors influencing the height of the waves include winds, earthquakes, volcanic eruptions, or underwater landslides. The size of the wave increases with the strength of the breeze.

Explanation:

The factors that influence the movement of ocean water include temperature, winds, the gravitational pull of the sun, the earth, and the moon, as well as warm and cold currents.

Explanation:

The twice daily rhythmic rise and decline of ocean water is known as a tide. the sun's and moon's powerful gravitational force on the earth's.

Explanation:

Life is water. Without water, existence is not even a possibility. Although its scarcity may cause many issues, its removal would undoubtedly result in the extinction of all earthly life. It is a priceless natural treasure. Every time we feel thirsty, we consume water. We use water for a variety of purposes, including washing garments, mopping floors, watering gardens, etc. Water is also necessary for the operation of industries. Water is therefore very important, so we must preserve it. Multiple issues have been caused by our negligent use of water. Any water that is present is of poor grade. For our own benefit, we ought to consider methods to preserve it.

Explanation:

The heat from the sun causes water to evaporate, which then drains into a watercourse or turns into water vapor. Clouds are created when the water vapor condenses after cooling. When these clouds get too heavy to float, they begin to descend as rain, snow, or sleet on land or water. The water cycle is the process by which water continuously alters its form and moves between oceans, the atmosphere, and the ground.

Explanation:

The ocean's top water rises and falls, creating waves. When gusts scuff up against the ocean's surface, waves are created. The size of the wave increases with the strength of the breeze. Huge waves are created when the storm's winds blast at a high rate of speed. Because these waves are so powerful, much devastation results. They could wreak enormous destruction.

Explanation:

Ocean currents are continuous lines of water moving in specific directions on the ocean's surface. Warm or frigid ocean currents are both possible. The warm ocean currents travel from their point of origin near the equator to the poles. Water is transported by the cold current from higher or arctic latitudes to lower or tropical latitudes. For instance, the Gulf Stream is a warm current while the Labrador Ocean current is frigid.

Explanation:

Rain and snowfall that falls on land eventually returns to the ocean. Several things can cause this.

Nearly all land areas are higher than ocean levels. As it rains, water runs down the land and into the sea. Rivers and streams are frequent forms of this water flow. During its journey to the ocean, water can occasionally become trapped in significant craters and natural basins. Lakes are created when rainwater fills craters or basins. If the lakes or basins have a river as an exit, the water will start to flow again in the direction of the seas.

Rainwater that falls on the ground is partially absorbed and appears to vanish in the earth. Evaporation and transpiration bring some of this water back into the atmosphere. Rest of it seeps deeper and deeper beneath the surface until it is blocked by rock strata that do not permit water to move through them. This liquid is referred to as groundwater. These same rocks that allow the water to pass through, nevertheless, might allow the water to seep through. Then a spring emerges from the water. Such springs supply water to a lot of lakes, ponds, and wells.

Ways of water harvesting in Delhi:

Water collection from residential, commercial, and other building rooftops: Rainfall that accumulates on the rooftops is piped down and gathered in pits. These pits have concrete linings on their sides. Yet, their bases are unlined and covered in layers of coal tar, sand, and stone chips. As the water slowly seeps through into the ground, these layers sift it. The groundwater level rises as a result. By raising the groundwater with hand pumps and borings, it can be used in the future.

Water collection at intersections: Because paved roads do not allow for groundwater infiltration, rainwater that falls there is completely squandered. By poking holes in the pavement around street intersections, this water can be collected. After being collected in holes beneath the pavement, the rainwater can then gently seep into the ground. This method of water collection is already being used at Jamia Hamdard University in Delhi.

You'll be astonished to hear that rainwater is still collected above ground for usage directly in our city. For instance, the Delhi jail inmates constructed a sizable pond made of cement to catch rainfall. The inmates' daily requirements are met by the rainwater gathered in this pond. Similar to this, there is a bus depot where rainwater is gathered and stored for use in washing buses. The rainwater that gathers there will be collected and sent underground through pipes under the flyover at the Dhaula Kuan junction.

Explanation:

Nature's gift of water is priceless.

We shouldn't squander it. Save as much water as you can.

Always watch out that your home's water tank does not overflow when it is being filled.

We waste up to 16 litres of water every minute if we leave the faucet running while brushing our teeth. We ought to fill a mug with water and use that as a substitute.

Instead of drinking water to water our gardens, we must repurpose the water used for dishwashing and utensil cleaning.
