1. Water cycle

   The water cycle, also known as the hydrologic cycle or the hydrological cycle, is a biogeochemical cycle that describes the continuous movement of water on, above and below the surface of the Earth. The mass of water on Earth remains fairly constant over time but the partitioning of the water into the major reservoirs of ice, fresh water, saline water (salt water) and atmospheric water is variable depending on a wide range of climatic variables. The water moves from one reservoir to another, such as from river to ocean, or from the ocean to the atmosphere, by the physical processes of evaporation, transpiration, condensation, precipitation, infiltration, surface runoff, and subsurface flow. In doing so, the water goes through different forms: liquid, solid (ice) and vapor. The ocean plays a key role in the water cycle as it is the source of 86% of global evaporation.The water cycle involves the exchange of energy, which leads to temperature changes. When water evaporates, it takes up energy from its surroundings and cools the environment. When it condenses, it releases energy and warms the environment. These heat exchanges influence climate. The evaporative phase of the cycle purifies water which then replenishes the land with freshwater. The flow of liquid water and ice transports minerals across the globe. It is also involved in reshaping the geological features of the Earth, through processes including erosion and sedimentation. The water cycle is also essential for the maintenance of most life and ecosystems on the planet.

1. Water cycle

   The water cycle, also known as the hydrologic cycle or the H2O cycle, describes the continuous movement of water on, above and below the surface of the Earth. Although the balance of water on Earth remains fairly constant over time, individual water molecules can come and go, in and out of the atmosphere. The water moves from one reservoir to another, such as from river to ocean, or from the ocean to the atmosphere, by the physical processes of evaporation, condensation, precipitation, infiltration, runoff, and subsurface flow. In so doing, the water goes through different phases: liquid, solid, and gas. The water cycle involves the exchange of energy, which leads to temperature changes. For instance, when water evaporates, it takes up energy from its surroundings and cools the environment. When it condenses, it releases energy and warms the environment. These heat exchanges influence climate. By transferring water from one reservoir to another, the water cycle purifies water, replenishes the land with freshwater, and transports minerals to different parts of the globe. It is also involved in reshaping the geological features of the Earth, through such processes as erosion and sedimentation. Finally, the water cycle figures significantly in the maintenance of life and ecosystems.

Examples of water cycle in a Sentence

1. Brad Udall:

   Climate change is water change, and many of the worst impacts we're going to see out of climate change are through changes in the water cycle, not only do we have to plan for these undesirable water outcomes, but we also have to get our act together and reduce greenhouse gases as fast as we can.

2. Krister Karlsen:

   While the deep water cyclecan effectivelychange sea level over hundreds of millions to billions of years, climate change can change the sea level in zero to 100 years, for comparison, the present-day sea level rise associated with climate change is about 0.1 inches (3.2 millimeters) a year. The sea level drop associated with the deep water cycle is about 1/10,000 of that.

3. Amy Williams:

   It helps us understand so much more about the water cycle on Mars, from orbital images, we knew it had to be water that formed the delta, but having these images is like reading a book instead of just looking at the cover. This is the closest I will ever get to going to Mars and doing this work in person. Seeing these rocks as I would in real life, looking up at them, is really staggering and really beautiful.

4. Hejiu Hui:

   We found a new mechanism that solar-wind hydrogen can diffuse into the glass beads and thus identified a new water reservoir on the Moon, on the other hand, impact glass beads are distributed in the regolith globally on the Moon. Therefore, the impact glass beads can be replenished with water on the Moon’s surface and can sustain the lunar surface water cycle.

5. Sarah Noble:

   For 40 years, we thought the samples were completely dry, we now understand that theres a water cycle, but we dont understand how it works.
