Water Cycle

Water waves are a mix of longitudinal and transverse waves. Particles of water actually travel in circles. If the particles move in clockwise circles, for example, then the wave propagates to the right.

To understand water waves, it's important to understand that water is not compressable. Sound waves are longitudinal waves where particles move back and forth and create areas of temporarily increased and decreased density and pressure. That is not possible with water waves, since the density can't significantly increase. Water also can't move as a transverse wave alone. If the height of the water increased without moving back and forth, the water would have to stretch vertically.

Instead, when water particles move toward each other to the crest of a wave, they also pile up and increase the height of the water.

Consider a wave propagating to the right. The particles move at their maximum rightward speed at the crest of the wave, so they catch up slightly with other particles still on the face of the wave. The height of water increases to the right. Then the crest passes the particle, and it begins to slow down because it tends to slide down the back of the wave. About halfway down the back of the wave, it has completed the first quarter of its circular path. It slows to a stop and starts moving left. At the trough of the wave, it is moving at its maximum leftward speed and has completed the right half of a circle. It is moving away from particles to its right, so the water height to its right decreases. Then the particle is caught by the face of the next wave. The face of the wave accelerates it to the right and slows its leftward motion until it stops about halfway up the face of the wave. Then it accelerates to the right until it reaches its maximum speed again at the crest of the next wave.

Particles under the surface of the water move too, motivated by variations in pressure. They move in similar circles to the surface particles, but smaller circles deeper in the water.

when it rains, the rain moves into a spot where it stays there, that's collection, and that's how it occurs

The three states of the water cycle are liquid, solid, and gas. In the liquid state, water exists as rain or bodies of water like lakes and rivers. It can freeze into solid ice or snow, representing the solid state. Water also evaporates into water vapor, a gaseous state, which rises into the atmosphere, where it can condense and eventually fall back to Earth as precipitation, continuing the cycle.

Ground water level is decreasing day by day.It needs to be replenished.

Air

Evaporation impacts the water cycle by changing liquid water into water vapor.

It's all part of a cyclic system. The water falls to the ground from clouds... it eventually runs into rivers and seas... it evaporates into water vapour forming clouds... which create rain. If the water didn't evaporate -the whole planet would be one huge ocean. - with no land to support life.

a drop of water may spend over 3,000 years in the ocean before moving on to another part of the water cycle

After formation of clouds, precipitation occurs. Hence, it is essential.

yes because its changing from one form to another form which is physical!!!

The leaves use only a small amount of water for photosynthesis (food-making) , so it releases the excess of water through the stomata (microsopic mouths on the leaves), turning the air humid. In fact, rain forest leaves give off so much water that the air is very humid.

How the water cycle and heat are related: Adding or subtracting heat makes the water cycle work. If heat is added to ice, it melts. If heat is added to water, it evaporates. Evaporation turns liquid water into a gas called water vapour. As water goes through its cycle, it can be a solid (ice), a liquid (water), or a gas (water vapour). Ice can change to become water or water vapour. Water can change to become ice or water vapour. Water vapour can change to become ice or water. If heat is taken away from water vapour, it condenses. Condensation turns water vapour into a liquid. If heat is taken away from liquid water, it freezes to become ice. The water cycle involves the sun heating the Earth's surface water and resulting in the surface water evaporating. The water vapour rises into the Earth's atmosphere. The water cools and condenses into liquid droplets. The droplets grow until they are heavy and fall to the earth as precipitation (which can be rain, freezing rain or snow).

On a large scale, the tilt of the earth is one major factor that causes weather changes, but the big answer is the sun! The sun is essentially responsible for all our weather.

you can set up (grow) thick grass along the river bank/sides

i dont know i needed this answer questioned people and u right nothing? why oh why i need this to bring grade higher

It increases growth of plants by 107%

A terrarium is an easy way to demonstrate the water cycle. The condensation forms on the glass exterior (cloud) and drops to the plants below (rain) the plants and soil evaporate the moisture (place moisture back into the ambient air) which in turn condensates on the glass ... completing the cycle.

The precipitation plays a big role in a water shed

Ice to Liquid Water -Energy is added to the ice in the form of heat -This energy causes the water molecules to (instead of vibrating in place like all solids) separate further away from each other, become more free-flowing, take the shape of their container. -As each molecule is heated above 0o Celcius, it becomes liquid. The center of the ice will take longer because the heat cannot penetrate it through the other ice. Liquid Water to Water Vapor -The liquid water molecules have enough energy to flow freely in their container obeying gravity. -Adding more heat causes them to gain more energy and separate even further. -When the molecules closest to the heat source reach 100o Celcius, they become gas and enter the air.

I had trouble understanding what you meant, so please excuse me if I'm answering a question you did not ask. People/plants/any living thing needs water to survive. This is because water gives you nourishment and keeps you hydrated. Humans are mostly made out of water, so if we didn't need it, we wouldn't be humans.

All three are important life-giving cycles. Every living organism needs water, carbon, nitrogen, and phosphorous to survive.and al play a very important role as well.

people that play a role in transporting water on Earth.

The energy source behind the water cycle is solar energy. It is the only energy which initiates water cycle.
