Question

What some fact about the water?

Answer 1

it is one of the compound that exists in solid , liquid and gaseous state................

Answer 2

H20

it is polar

it has a high surface tension

it is less dense as a solid

it contains hydrogen bonds

all of these give us life the way that we know it

Answer 3

— There is the same amount of water on Earth today as there was 3 billion years ago.

— About 70% of the earth's surface is covered in water, and  97% of that is salty or undrinkable.

— Three percent of the water on Earth is freshwater, but 2.997 % of that is locked up in icebergs and glaciers.

— Only 0.003% of the world's water is available to us for all our needs and uses.

— Of the total world's freshwater supply, over two thirds is found underground.

— There is a limited supply of fresh water in the world and about 25% of this fresh water is in the lakes and rivers of Canada.    Water is a precious resource.

— Toilets (while consuming nearly one quarter of our municipal water supply) use over 40% more water than needed

— Many homes lose more water from leaky taps than they need for cooking and drinking

— substance that is found naturally on earth in three forms or states:

- solid: - polar ice-caps, glaciers, icebergs

- liquid: - oceans, seas, lakes, rivers

- gas: - air/atmosphere

— Hydrologic Cycle consists of :Evaporation, Transpiration , Condensation, Precipitation and Melting

— average ocean salinity is 35 ppt. ( parts per thousand )

— Black Sea is so diluted by river runoff, its average salinity is only 16 ppt

— Freshwater salinity is usually less than 0.5 ppt.

— Water between 0.5 ppt and 17 ppt is called brackish. example is estuaries

—Waves are caused by the wind blowing over the surface of the ocean.

— Another movement of water is called ocean currents. Currents can be compared to rivers traveling along the surface of oceans and deeper waters.

— Tides occur everyday as the water level of the oceans increases and decreases.

— Rain is the raw material of rivers, streams and lakes.

— oceans sustain life on this planet

— Landfills, leaking gasoline storage tanks, leaking septic tanks, accidental spills and farm land treated with pesticides and fertilizers are a few examples of how we are treating our precious groundwater.

— Fourteen billion pounds of garbage are dumped into the world's oceans each year!

— Water consists of three atoms, 2 Hydrogen atoms and an Oxygen atom,

— Water regulates the earth's temperature

— Water freezes at zero degrees Celcius or 32°F

— Frozen water is 9% lighter than water, which is why ice floats on water

— Each country has its own water quality standards

— Over 90% of the world's supply of fresh water is located in Antarctica

— earth's total amount of water has a volume of about 344 million cubic miles

— Water makes up 83 percent of our blood & 70 percent of our brain

— A person takes in about 16,000 gallons of water in his or her lifetime on the average

— The only water we will ever have is what we have now

— If all of the world's water were fit into a one gallon jug, the fresh water available for us to use would equal only about one tablespoon.

— Water boils at 212°Fahrenheit or 100° Celsius

— More than 1 in 6 people remain without access to safe drinking water

Answer 4

Wow, I think Critters has answered it all, except that it is one of the few substances we cannot do without. (Food and air are the others.) It makes up 96% of the human body and life began in it.

Answer 5

Water is colourless and odourless.
