Is most of the water on earth salt water or fresh water?
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 surface.
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

What is between the moon and earth causes tides in oceans?
Mutual gravitational forces between the Earth and Moon are.
How is hydrology related to agriculture?
livestock is a part of agriculture. It is one of those branches that makes up agriculture
Tides are caused by both the Sun and The Moon. Tides are the result of both Gravity and momentum.
Gravity attracts objects. This causes water on the Earth to rise up on the side of Earth facing the Sun and the Moon.
Momentum tries to continue in the same direction. This causes water on the opposite side from the Sun and the Moon to rise up and keep going in the direction it was going as Earth turned away in response to the Sun's and the Moon's gravity.
The Earth is also rotating. This brings different areas of the surface into line with the directions of gravity and momentum. To observers on the Earth, it appears that the tides rise and fall two times each day. But actually, the Earth's rotation has carried the person into the higher or lower regions caused by gravity and momentum.
Since the Moon is orbiting the Earth, and the Earth is orbiting the Sun, sometimes there is an alignment between all these things. This causes the highest tides because the tides of both Sun and Moon will join together.
The lowest tides occur when the Earth is at a 90° angle between the Sun and Moon. The tides of the Moon and Sun are at that time subtracting from each other.
A sudden drop in extreme velocity will deposit sentiments in a pattern called what?
Possibly a delta or alluvial fan.
Is precipitation the source of all fresh water on earth?
Fresh water - i.e. that on land - yes, to all intents and purposes is from the condensation and precipitation of water evaporated from the sea. A relatively tiny amount of water is released by volcanoes above subduction zones, but otherwise, the question's thesis is basically correct.
Which phase of the moon produces the least variation in tides on earth?
During the first and third quarter phases of the moon, known as the neap tides, the gravitational pull of the sun and moon work against each other, producing the least variation in tides on Earth. This results in lower high tides and higher low tides during these phases.
What are the basic hydrological requirements for river basin development?
The drainage basin includes all the surface water from rain runoff, snowmelt, hail, sleet and nearby streams that run downslope towards the shared outlet, as well as the groundwater underneath the earth's surface.
What is percolation in hydrology?
Percolation in hydrology refers to the process by which water travels through the soil and permeable rock layers, eventually reaching groundwater reservoirs. It plays a crucial role in the water cycle by replenishing aquifers and providing water for plants and ecosystems. The rate of percolation is influenced by factors such as soil type, vegetation cover, and precipitation intensity.
Where is almost two thirds of earth fresh water located?
According to the Fresh Water entry in Wikipedia:- Out of all the water on Earth, only 2.75 percent is fresh water, including 2.05 percent frozen in Glaciers, 0.68 percent as Groundwaterand 0.011 percent of it as Surface_waterin lakes and rivers.
Freshwater lakes, most notably Lake_Baikalin Russia and the Great_Lakes_(North_Americain North America, contain seven-eighths of this fresh surface water. Swamps have most of the balance with only a small amount in rivers, most notably the Amazon_River.
The atmosphere contains 0.04% water. In areas with no fresh water on the ground surface, fresh water derived from precipitation may, because of its lower density, overlie saline ground water in lenses or layers.
Most of the world's fresh water is frozen in Ice_sheets.
What do you call the place underground where water accumulates and circulates?
An aquifer is an underground accumulation of water.
What motion of earth causes the cycle of tides that occurs each day?
The movement of the Earth around the Sun produces changes in both the duration and angle of the sunlight reaching any particular location. Because the Earth axis (the line around which it spins) is tilted with respect to the flat plane of its orbit, different latitudes will receive more solar energy in some parts of the year than others. This is not caused to any great extent by the changing distance between the Earth and the Sun (this only varies by about 3% during the year).
The tilt causes one hemisphere to receive much more solar radiation (long days, more direct angle) during a part of the year, while the opposite hemisphere receives correspondingly less. During the spring and fall, there is not much difference. But from late December to late March, it is winter in the Northern Hemisphere and summer in the Southern Hemisphere. Six months later, from late June to late September, it is summer in the northern and winter in the southern.
Are lunar tides causing the moon to recede from Earth?
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.
How does the moon affect the tides on the side of earth facing the moon?
There are high tides on the side of Earth facing the moon.
What is the relationship between the moon sun and earth during high tides?
All three are in line, so the Moon is either opposite to the Sun (close to full moon), or in the same direction as the Sun (close to new moon).
What cause the earth to experience high and low tides daily?
The earth's rotation and the proximity of the moon (and the sun to a lesser degree) cause high and low tides each day.
What is the connection of the tides the moon and the earth?
Tides are caused by the gravitational pull of the sun and the moon upon the oceans of the earth. The sun has the greatest pull. The tides are greatest during a new moon when the sun and the moon are pulling from the same direction. The side of the earth that faces the sun usually has the high tide, while the side away from the sun has the low tide.
What are Water vapors that rise from plants into the air?
Transpiration is a process in the Hydrological Cycle where moisture carried through plants changes into vapor and is released from leaves into the atmosphere.
If the moon moved around the earth faster, while the earth maintained the same rotational speed, the period between spring and neap tides would be less.
Spring tides occur when the sun moon and earth?
Spring tides (which are a little higher than average) occur when the Sun, Moon and Earth are pretty much lined up; at the new moon and the full moon.
Lower-than-average "neap" tides happen at the 1st and 3rd quarter moon phases.
What are you likely to find where the water table intersects the land surface?
You'll find a lake or a moor depending on the runoff properties.
What events on earth may affect the tides?
add Well, tides are regular movements of the ocean, and are caused by the gravity effects of Moon and Sun.
Wind may cause regular pulsations on long narrow lakes, and these are called a seiche.
A meteorological high or low will alter the sea level, but these are not regular enough to be called tides.
