What would happen to the water cycle without the sun?
Water constantly moves around the Earth and changes between solid, liquid and gas. Without the Sun there would be no water cycle, which means no clouds, no rain—no weather!” “And without the Sun’s heat, the world’s oceans would be frozen!” added Marisol.
Why are gravity and the sun important to the water cycle?
While sunlight is the energy source, the greatest force propelling the water cycle is gravity. It pulls precipitation down from clouds and pulls water downhill. Gravity also moves air and ocean water. Cool, dry air is denser than warm, humid air, and cool, salty water is denser than warm, less salty water.
Why is the sun considered the boss of the water cycle?
The real boss of the water cycle doesn’t even live here on Earth. The sun is what makes the water cycle work. This process allows liquid water to evaporate into water vapor, which in the main way water gets from the land surface and oceans back into the sky.
Why is the sun important?
The Sun. The sun has extremely important influences on our planet: It drives weather, ocean currents, seasons, and climate, and makes plant life possible through photosynthesis. Without the sun’s heat and light, life on Earth would not exist.
How does the sun affect humans?
Excessive exposure to the sun is known to be associated with increased risks of various skin cancers, cataracts and other eye diseases, as well as accelerated skin ageing. It may also adversely affect people’s ability to resist infectious diseases, and compromise the effectiveness of vaccination programmes.
What are the 5 steps of the water cycle?
The entire process of water cycle takes place in almost five steps which includes the evaporation, condensation, precipitation, infiltration, and runoff. To begin with, water gets evaporated from the water bodies on the surface of earth like rivers, oceans etc. into the overlying atmosphere.
What drives the water cycle?
The sun, which drives the water cycle, heats water in oceans and seas. Water evaporates as water vapor into the air. Some ice and snow sublimates directly into water vapor.
What are the benefits of the water cycle?
Advantages of Water Cycle. The advantages from the water cycle are that the earth’s population doesn’t have to produce any more water than what we already have because we use the same water. · Provides water for our population, animals and plants.
What is the Order of the water cycle?
Steps of the Water Cycle Evaporation. The first water cycle step starts with the atmosphere pulling water out of the big bodies of water. Condensation. Next up in the water cycle steps is condensation. Sublimation. Here is one of the additional and smaller steps I mentioned before. Precipitation. Transpiration. Run Off. Infiltration.
