The water cycle iss a process which helps to circulate and replenish water on earth.

<h3>What is hydrology?</h3>

Hydrology is the scientific study of water bodies , the changes that occur in them as well as the various features and behavior of water bodies such as oceans and rivers.

Water circulation created by prevailing wind systems. The Gulf Stream is an example up of the Coriolis effect.

The length of open sea over which wind can blow steadily to create waves is called fetch.

Salinity is the amount of dissolved salt in a liquid

The distance from the crest of one wave to the crest of another is called wavelength

Water circulation created by differences in density deepwater currents

Energy is what moves forward and through a wave.

The cyclical process of the changing state and movement of water around the Earth through evaporation, condensation, and precipitation is called water cycle.

As the amount of salt in water increases, the density of the water increases.

The type of energy possessed by moving water is called kinetic energy.

The rising of ocean water bringing nutrients up from the deep us called upwelling.

Therefore, the water cycle helps to circulate and replenish water on earth.

How many electrons are in an element if the atomic number is 11?
tatuchka [14]
The answer is sodium 
Sodium has 11 protons (atomic number is 11) and has one valence electron. As the Bohr model diagram below shows, Sodium has 11 protons and 12 neutrons<span> in the nucleus to make the mass number 23. The 11 electrons necessary to make Sodium neutral (protons = electrons) are arranged in a pattern of 2-8-1.</span>

What does it mean to say that a wave is cyclic, or periodic, disturbance?
Zina [86]

Answer:

Wave is a disturbance or energy that propagate through medium from one point to other point

So basically it is a flowing energy that flows into the medium and hence medium particles start oscillating about their mean position to and fro.

This motion of medium particles or this to and fro motion is about their mean position and this will always be cyclic or periodic motion

This means the disturbance or energy continuously flow through the medium such that it will change the position of medium particle and this will be cyclic in order

For an example

y(x,t) = Asin(kx - ωt + φ)

So here above equation of wave is a travelling wave in which displacement of medium particle from its mean position is given by "y"

Now we can see that this disturbance depends upon the sine function and it will repeat its same position after every 2 pi time interval as it is cyclic function for this value

Due to this phenomenon of repetition of its same position we can say that it is disturbance of wave is cyclic.
