How does the sun and moon produce the regular rising and falling of tides on earth?
Where is most of the Fresh water on Earth?
Short Answer:
Of all fresh water on Earth, 69% is frozen. And, even it it melts through global warming, most of it goes into the ocean. Basically, all the water we get is either from rain or what is pumped up from the rapidly diminishing aquifers.
There is not really much fresh ware on Earth. 1.74% of all Earth's water is in this frozen form as ice caps, glaciers and snow.
Only 0.75% of Earth's water is liquid water and potentially accessible as fresh water in ground water, lakes, streams and swamps.
Long Answer:
About 97.5% of water on Earth is salt water and 2.5% fresh water.
All of the oceans are salt water and the oceans represent more than 96% of all water on Earth.
Of the 2.5% fresh water, only 0.3% is in liquid form on the surface. Most of the rest is frozen or underground. Less than .01 % of all water is in lakes and rivers.
A breakdown of the various forms of water is as follows, going from the largest to the smallest.
96.5000% Oceans, Seas, bays
1.7400% Ice caps, glaciers, snow
0.9400% Saline Groundwater
0.7600% Fresh groundwater
0.0220% Ground ice and permafrost
0.0070% Fresh Lakes
0.0060% Saline Lakes
0.0010% Soil moisture
0.0010% Atmosphere
0.0008% Swamps
0.0002% Rivers
0.0001% Biological
In rivers, lakes, in the atmosphere, in the water table, and as ice held on land in the form of snow and glaciers (especially the antarctic and Greenland).
99% of all the water on the Earth is not considered fresh water. Only one percent is. It is in lakes, rivers, streams, icecaps on mountains and frozen in the polar caps or glaciers. See the related link for more information.
How much usable fresh water is there on Earth?
Around 8 to 10 million cubic miles of Earth's water is considered fresh water, of which some 6 to 7 million cubic miles (more than two-thirds) is frozen in glaciers and the ice caps in Greenland and Antarctica.
What alignment of the earth moon and sun cause the spring and neap tides?
The Earth's 23.5 degree tilt with respect to the orbital or ecliptic plane causes the Sun to rise higher in the sky during the summer months and lower in the winter months.. The spring and autumnal equinoxes correspond to the days on which the Sun is positioned directly over the equator and is observed to rise directly in the Eastern sky, resulting in exactly the same amount of daylight and nighttime everywhere on Earth.
What is the reservoir for most fresh water on earth?
Most of the fresh water on Earth is stored in glaciers and ice caps, particularly in Antarctica and Greenland. Approximately 68.7% of the world's fresh water is locked away in these frozen reserves. The remaining fresh water is found in groundwater, surface water bodies like rivers and lakes, and in the atmosphere. This makes glaciers and ice caps the largest reservoir of fresh water, significantly influencing global water availability.
What happens to timber when heated?
Slowly heated timber would simply dry and become classed as seasoned. If steam is used, the timber would become pliable, and could be bent - resulting in the curved handle on a walking-stick, for instance.
WhWhat percentage of Earth's water is fresh water?
About 3% and only 1% is able to be drank. The rest is frozen in ice caps and glaciers.
Where do the water bulges occur on earth during the tides?
bulges of water in the ocean are called high tides.
What causes the tides to rise and fall and fall on Earth?
The tidal effect (guess where it got that name) caused by the gravity of the Sun and Moon.
Is there water on other planets or this one?
not really because of global warming glaciers are melting and because of amount of water we are wasting every day when all the glaciers will melt none amount of water will be left so save water and electricity because lot of water is used to generate electricity.
How is hydrology like oceanography?
Hydrology is like oceanography in that both involve the study of currents and their effect overall on the bodies of ocean water. Hydrology is different because unlike oceanography, it deals solely with the movement of the water.
What is the meaning of the term hydrology?
It is when water passes through the atmosphere as water vapor. Also Gucci Mane is better than Drake,Lil Wayne,Justin Bieber and anyone else out there and northwest Jackson middle school ms.Lewis class love ya
What are the disadvantages of using groundwater?
There are several problems: # This aquifer carries water to the oceans, just like above ground rivers do. This cuts off a nutrient and thermal source that ocean life depends on. # This aquifer commonly supports the land above it, so removing the water can create sink holes. # This aquifer commonly supplies multiple wells, so removing water at a new place may change how much and how deep others may have to go, and what contaminants they will see. # This aquifer frequently contains things that are unsafe to be drunk, so additional treament will be necessary. (Water quality usually changes more slowly for groundwater sources, than does a river, so that helps.) # Drawing water from this aquifer draws additional organisms from the vadose zone (and above), which will alter water quality over time. # The hole fails over time (ground settles, casings corrode, other wells lower water table), and additional expense has to be spent on into the future to maintain / repair / abandon it.
Why are there high and low tides on earth?
This one had me for years. Start by assigning some simple values to the gravity of the moon on certain places around the earth. Assume that the pull of the moons gravity when directly above say England is at level 10. That causes a lump of water on that side of the ocean. You may remember that the pull of gravity decreases with the square of the distance, so while there is a significantly less force( lets say a 9) pulling at the water 8,000 miles away on the other side of the world, the ocean literally floats a bit higher there. Of course on the sides we see a low tide. There is a whole plethora of physics to explain why the 2 high tides are about equal, but that's basically the reason for the two.
Why do astronauts look for water on other planets?
If there is water on mars, there might be life on mars, and if there is life on mars, that means that humans could survive there as well.
Even if there isn't life on Mars, the water would mean that people would be able to go there and maybe even live there without having to rely on bringing water in space ships.
What percentage of earth is made up of fresh water?
About 3 percent (2.75%) of the total water on Earth is fresh water, and as much as 75% of that is locked up as ice in glaciers and polar caps. Most of the rest is groundwater or water vapor in the air. Thank you!
How is fresh water distributed on earth?
Fresh water on Earth is distributed mainly in the form of glaciers and ice caps (68.7%), groundwater (30.1%), and surface water such as rivers and lakes (0.3%). The remaining small percentage is found in the atmosphere as water vapor. This distribution is constantly changing due to factors like climate change and human activities.
What do you call a person who studies hydrology?
For horseisle, the answer is water
/////Dreygon on roan\\\\\
What are tides patterns on earth?
Tides are caused by the gravitational pull of the moon, rising and falling as the moon orbits the earth AND the earth turns.
