The household wastes like paper, plastics, glass and metal objects present in the garbage can be recycled. These junk dealers send the discarded articles to the respective factories or mills for recycling. In order to recycle used and discarded materials, we should first separate our household garbage properly so that the waste materials which can be recycled do not get dumped alongwith other household garbage which is to be thrown away.

The Water Cycle Diagram of the water cycle showing evaporation, condensation, and precipitation Diagram of the water cycle Precipitation is a vital component of how water moves through Earth’s water cycle, connecting the ocean, land, and atmosphere. Knowing where it rains, how much it rains and the character of the falling rain, snow or hail allows scientists to better understand precipitation’s impact on streams, rivers, surface runoff and groundwater. Frequent and detailed measurements help scientists make models of and determine changes in Earth’s water cycle. The water cycle describes how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation. The water falling on land collects in rivers and lakes, soil, and porous layers of rock, and much of it flows back into the oceans, where it will once more evaporate. The cycling of water in and out of the atmosphere is a significant aspect of the weather patterns on Earth.

The cyclic movement of water from the atmosphere to the Earth and back to the atmosphere through various processes is called as water cycle.
Different steps of water cycle include evaporation, transpiration, condensation, precipitation and surface run-off.
a) Evaporation - The water present on the surface of oceans evaporates by the sun’s heat. This process of conversion of water from liquid state to vapour state is called evaporation. Evaporation also takes place from wet clothes, fields, ponds, lakes and rivers.
b)Transpiration - Plants take in water from the soil to prepare their own food and also for other life processes. They release excess water into air in the form of water vapour by the process of transpiration.
c) Condensation - The evaporated water is carried away by warm air. As the warm air moves higher from the surface of the Earth, it starts to cool down. This water vapour condenses to form tiny water droplets which float in air to form clouds or fog.
d) Precipitation - All these droplets collect to form bigger drops of water. Bigger water drops come down ads rain by the process of precipitation. If the air is too cold, the water drops can become snow or hail and may settle on the top of a mountain. When these snow or hail melts, they can become part of a river or a stream.
e) Surface run-off – Some amount of rain water is absorbed by the soil and settles down as ground water. Most of the rain water flows down the hills and mountains to collect into rivers, lakes or streams. Rain also washes away the topmost layer of the soil into water bodies.
This circulation of water through all these different factors is called as water cycle.

Yogita Ingle 7 years ago

Camels are known as ships of the desert because they can move across desert sands easily providing a mode of transportation for people in desert areas. They can eat almost anything and drink from waterholes that are bitter or saline. Also ,In the daytime, when the sun is high, the eyes do not allow excessive light in. Glands supply the eyes with a great deal of water to keep them moist. Thick eyebrows shield the eyes from the desert sun.
