Most of the liquid water on Earth is found in the oceans, in fact the percentage is so big that it comes as if almost all liquid water on our planet is in the oceans while the water from the lakes, rivers, ponds etc. is just a minor part of the whole.
The water from the oceans contains salt, thus making it a salty water and not suitable for drinking as it is naturally. For this water to be consumed and be part of the daily of the humans for drinking it needs to be desalinated. Desalination is a process that gets the salt out of the water and makes it suitable for drinking. This is not an unknown or untested process, it is something that is practiced for decades now mostly on the Arabian Peninsula where there isn't any fresh water resources.
The oceans are one of the major elements that influence the climate around the globe. They are massive water bodies, being able to accumulate and release enormous amounts of gasses from and into the atmosphere. Also, the ocean waters are an excellent heat storage, as the water has a property to cool down and warm up relatively slowly, so once its warmed up it tends to keep the temperature much higher at the places near the coast. The ocean waters are constantly on the move because of the difference in temperature and density. With the movement of the water they create air masses that follow them, some warm and wet, some cold and dry. The places that are influenced by the oceans have their climates modified mostly by them, with the most common characteristic being that the temperatures extremes are lacking, so the climate tends to be milder in all seasons, or at places it remains the same for the whole year.
The space time continuum meaning that time travel would be very much possible if humans could break the barrier of the 4th dimension
The circumference of circle is 20.096 units
<em><u>Solution:</u></em>
Given that circle has a diameter with endpoints at (10, 8) and (5, 4)
To get the diameter, find the distance between the end points
<em><u>The distance between two points is given by formula;</u></em>

Here the points are (10, 8) and (5, 4)

Substituting the values we get,


Thus the diameter is 6.4 units
<em><u>The circumference of the circle is given by formula:</u></em>

Where "d" is the diameter of circle

Thus circumference of circle is 20.096 units
I'm a bit confused on what's happening here. But if you want to fill me in message me plz :)
