The water cycle تعبير

Water plays many different roles on the Earth. But most of the water on Earth is in the oceans. Some is vapor in the atmosphere. Water is essential for life as we know it. The first process is evaporation and the transformation of the water into vapor.

The water cycle starts from the ocean where the sun warms the water. Then the water vapor rises to the top and it condenses when exposed to the cold air, then the condensed water moves inside the clouds and falls again in liquid form. Water cycle , also called hydrologic cycle , cycle that involves the continuous circulation of water in the Earth-atmosphere system. Of the many processes involved in the water cycle , the most important are evaporation, transpiration, condensation, precipitation, and runoff.

The Water Cycle (also known as the hydrologic cycle ) is the journey water takes as it circulates from the land to the sky and back again. Plants also lose water to the air (this is called transpiration). The following article explains a little more about the water cycle , in which water circulates from the land to the air in a continuous cycle. Since the water cycle is truly a cycle , there is no beginning or end.

Our online water cycle trivia quizzes can be adapted to suit your requirements for taking some of the top water cycle quizzes. In general, water evaporates from oceans, then it condenses in the atmosphere as water vapor cools. Teaching about the water cycle has never been so important. The sun is the driving force of the water cycle.

Whenever water changes from one state to another and moves from one place to another, it either gives off energy or absorbs energy. Water gets into the sky and goes back to the earth again. First, the sun heats water. Then, water changes into water vapour.

After that, the water vapour changes into clouds by the cool air. Finally ,the clouds fall as rain. We can’t live without water. Observing the Water Cycle.

Orbiting satellites are now collecting data relevant to all aspects of the hydrologic cycle , including evaporation, transpiration, condensation, precipitation, and runoff. NASA even has one satellite, Aqua, named specifically for the information it is collecting about the many components of the water cycle. All About The Water Cycle - How Does It Work?

The human body is composed of water. An average human (weighs 1lbs.) has gallons of water in the body ,and a negligible loss of 1. Water exists in three different states in the water cycle – Besides being liqui water can also exist as vapor (gas) and as ice (solid). While the amount of water on earth remains constant, the amount of water that exists as either liqui soli or gas always vary. The USGS Water Science School offers the most comprehensive information about the water cycle anywhere, and our diagrams and information is available in many languages.

For schools and kids, we offer our diagram and explanations in over languages, and our more advanced diagrams and summaries are available in over languages. Here’s a collection of some of our favorite books about the water cycle. 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 heat of the sun makes tiny drops of water evaporate from the sea حرارة الشمس تجعل قطرات المياه تتبخر من البحر They rise in the sky and sometimes form clouds. Rain is a kind of precipitation.

Precipitation is any kind of water that falls from clouds in the sky, like rain, hail, sleet and snow. A rainstorm is a sudden heavy fall of rain. It may cause flash floods in valleys.

It is measured by a rain gauge. Heavy rain for a long time may make floods on floodplains.
