Hydrology

Parent Category: Earth Sciences
Hydrology studies the movement and distribution of water across planets.
It is the main water source for many city's
Because the shapes of bays, inlets, and the ocean floor can affect the flow of water.
I think it helps thinking of Earth as being "pulled apart" by the  difference in gravitation, by the Moon, on both sides of Earth (the  nearer side, and the farther side).
Typically there are two high tides a day. Think of it as two giant waves going around the world constantly.
It's North America's Great Lakes. So if you were answering a question like this one, you would say something similar to this: The continent that has half of the earth's fresh water is North America's Great Lakes. Hope this helps!
the distance of the moon from the earth the total gravity of the moonthe amount of water in the tide.....and ect by J.P.A
  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 Earth's tides are caused mainly by the gravity of the moon.   There are several other questions and answers dealing with this topic; it is popular. Do a search, and you will find lots of other details.
The high tides would become lower and the low tides would become higher.
I'm looking for some answers on my questions! Why is this website called Answers.com if not all the questions are answered? Sorry, but I think I'm in the wrong website. -this is a comment, not the answer.
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!
This is a tricky question; scientists don't have any definitive answers but there are several compelling theories that explain why Earth has water while some of the other planets don't. Compare Earth to its two neighbors; Venus and Mars. Venus is about the same size as Earth, but it's a hot hot...
This is because life as we know it cannot exist without water. We do not rule out that other planets have different forms of life. Scientists just believe this to be not likely at all.
Glaciers. Glaciers are the enormous reservoirs of frozen water on the hat of the planet. on the top. Northern regions of the world. all the fresh water springs down from those regions to the south of the planet. lakes, rivers, mountains, valleys carry the water through out the lands. This is the...
Well the moon does most of the work, and the sun is so far away it has very little influence. Hope I helped:D
The moon's gravity changes the tides in oceans and seas.
It slow down the rotation of the earth due to friction of water motion acting on to earth surface. The earth spin is slowing down by about 1.5-2 milliseconds per century.
No, the moon does. Back when the moon still rotated, earth's gravity would have induced a small amount of tidal motion in the lunar regolith, just as the moon induces tides in earth's crustal rock. These tides are not large, just fractions of an inch (millimeters). The tides in free flowing...
About 97.5% of water on Earth is salt water and 2.5% fresh water. More: The total volume of water on Earth is estimated at 1.386 billion km³ (333 million cubic miles). About 97.5% of water on Earth is salt water and 2.5% fresh water. Of the 2.5% fresh water, only 0.3% is in liquid form on the...
Frozen in the icecaps (in the form of ice at the poles).
Because of the moon
Tides are differences in gravitational pull between two points of a body. Tidal effects on earth are caused by lunar gravity and, to a much lesser extent, solar gravity. The greatest effect of tidal forces are on water levels along ocean coast lines. The ebb and flow of this water is also known as a...
The gravitational pull of the Moon has the greatest influence on the Earth's tides but the Sun also has some effect.
3% of the earths water, is fresh water
It would mean that the Earth had stopped rotating. Even the complete disappearance of the Moon would not stop the tides, because the Sun has a lot of influence on them too. Even without the Moon, there would still be substantial tides, as long as Earth continued to rotate. (Also note that if...
Well 70% of earth's surface area is made out of water 97% of that 70% is salt water So no, 75% of earths water is not fresh water only 3%
the sun has a much smaller effect than the moon. the moon pulls anything toward it wherever it is over earth, which is usually ocean due to the fact that earth is almost all water, so the moon pulls ocean water toward it, causing rougher seas
The tide will be high when the moon is visible because of it's gravitational pull.
Recently, they found a puddle of water on Mars.Yes there is water on Mercury in the core, it has a liquid core some of its astroids also have water within them.
Spring tides occur in principle when the three objects are lined up  so that the gravitational forces of the Sun and Moon are combined.  In practice in many places the spring tides occur 1-2 days later.    Tides are a proximity effect, which means that the Moon's effect on  the tides is the...
Mars has dry ice on both polls
The moon, sun, earth, and tides are all related because of the tidal effect. The earth's oceans are pulled by both the moon and the sun to generate tides.
Hydrology is a branch of earth science. To make a comparison, consider that chemistry is a physical science, and biology is a life science.
There are two major reasons for the high and low tides on opposing sides of the planet. 1) The Moon and Earth make up what we call the Earth-Moon system; they interact in a special way. It is not the moon that is doing all the orbiting while the earth is somehow 'still'. They orbit each other....
Assuming you mean "How much of the water on Earth is fresh water", about 5% of the water on the Earth is fresh water, as opposed to about 95% salt water.To anser your question directly though, 100% of the fresh water we know about is on Earth. There is some water on other celestial bodies, but I...
yes, tides would differ because of the difference in gravitational pull that would be created due to mars.
There is a gravitational pull that exists between the planetarial masses of the earth, moon sun respectively.The stronger force exists between earth and moon as far as tides are concerned.As the earth and moon orbit each other on a daily basis a gravitational pull is exerted on a section of ocean...
Because unlike our planet, others don't have the right balance of moisture, they are either to hot or at a frozen temperature. One of the main reasons, though, is because while are planet was still creating itself when it there was just lava Comets that have ice were able to give earth oceans over a...
Simple Answer:Water flows downhill. The ocean is as far downhill as water can get.  Oceans are roughly 97% of Earth's water and cover 70% of Earth's surface. Since oceans have salt, most of the water on Earth is salt water.  Why the oceans have salt is a related question. (See link.)Why...
Percolation is basically the movement of water as it infiltrates the permeable soil in the ground.
While the moon is slowly getting further from Earth, it is not the fault of the tides that this is happening. The moon is actually traveling ever so slightly faster then it should be to maintain its orbit, it always has been, since it was formed. So each revolution, it gets a little further away.
Iron was an abundant material when the solar system formed. It is present in all of the terrestrial planets and asteroids. Uranus and Neptune are believed to have an iron-nickel core, so it would not be unlikely that Jupiter and Saturn also had some iron in their core. But Mercury, Venus, Mars and...
Hydrology is very important in Civil Engineering because water affects all aspects of construction . From the cohesion of soluable aggregate interaction to the effects of direct flooding in and around all areas of construction , we must study and use all the facts present about how water will find...
Most of the water on Earth is undrinkable, about 99%, only 1% of the water on Earth is drinkable, and only half of that is easily available!
Fresh water is naturally occurring water on the Earth's surface  with low concentrations of dissolved salts and solids. Fresh water  can be found in ponds, icebergs, rivers, and groundwater aquifers.
well na there are no such things as tides jokes tides are the second iportant things in space
At new moon, the tides will have their maximum excursion - both highest and lowest. This is because the tidal effect of Moon and Sun are then additive. At full Moon, the high and the low tides will be closest together in distance, for the gravitational pull of the Moon and Sun tend to oppose.
The gravity of the Earth holds the water of the oceans to the surface of the planet. The gravitational pull of the Moon (and to a lesser but still measurable extent that of the Sun) pulls water from the Earth and the Earth from the Water! that is why there is a tidal water bulge on the same and on...
Rain returns fresh water to the earth. There are also underground aquifers and springs that supply some of the worlds water to humans and other forms of life. Also, melting glaciers add to the worlds water supply.
We wouldn't care, because the amount of energy it would take to stop the Earth from spinning would destroy the planet anyway. Eventually, billions of years from now, IF the Earth and Moon survive the expansion of the Sun into a red giant, the Earth's rotation will slow down and the Earth will...
hydrulics dealing with the mechanical properties of liquids. Fluid mechanics provides the theoretical foundation for hydraulics, which focuses on the engineering uses of fluid properties. In fluid power, hydraulics is used for the generation, control, and transmission of power by the use of...
  Whereas an oceanographer's studies concern oceans, a hydrologist's studies concern land water.
The gravity of the moon and sun combine to pull Earth's waters in the same direction.
They exert a gravitational force on the earths water masses, during full moon high tides are higher than normal and low tides are lower than normal, this is known as 'spring tide'. These are natural conditions that bring with them stronger than normal currents and stronger than normal rip currents...
From the pull of the moons gravity.
Yes, this is the established convention. (Though for the past few years now, a select few rebel scientists have postulated that tides are being caused by mountains on the other side of the earth. We may never understand those rebel scientists.)
The moon causes the earths water to have a low tide or a high tide
When the are aligned, tides are largest. When they are at right angles, tides are weakest.
Hydrology is the study of water AND H20 that's how the name starts with hydro.
Tides are caused by the Moon's and the Sun's gravity. Seasons are caused by the 23.5 degree tilt of the Earth's axis with respect to the plane of its orbit around the Sun, which result in the northern and southern hemispheres having varying amounts of energy from the Sun.
the moon is the nearest neighbour of earth and earth have gravitythe movement of the moon affects the tides of the earth by.........................a force called gravity, acctually the moon pulls the water from seas, oceans and rivers towards it by the force gravity which is in earthmy english oh!
because the moon is closer to the earth at certain times so there for the gravity is pulling one side while the other is pulling so that's how they are on opposite sides of the earth at the same time.
Oceans are not the source of fresh water on Earth. Drinking water primarily comes from 4 sources. Lakes, rivers, groundwater, and glaciers. (Of course, all of it is purified before it reaches you.)
Yes, Tides are periodic rises and falls of large bodies of water. Tides are caused by the gravitational interaction between the Earth and the Moon. The gravitational attraction of the moon causes the oceans to bulge out in the direction of the moon. Another bulge occurs on the opposite side, since...
Water is what created us is what is life about
You can find some fresh water in the sky and in glaciers [etc.], but if you want to know where most of LIQUID fresh water is, then it would be ground water.
Tides are caused mainly by differences in how much gravity from the moon and the sun pulls on different parts of the Earth.
It all has to do with the moon. The moon is always in the sky you just cant see it throughout the day. During the morning/day time the moon is not as visible and has more of a gravitational pull causing the water to recede. BUT when it becomes evening/night the moon has less of a gravitational pull...
Your penis is not a weapon
The majority of fresh water is frozen in polar ice caps. The largest fresh water lake is Lake Bakal.
