Do lakes and streams hold more than two thirds of earths freshwater?
oceans freshwater and lakes and streams cover 2/3 of earth
Would a boat floating in a sea have more or less upthrust than the same in freshwater?
Assuming its weight hasn't changed, then as it is floating, the upthrust on it equals its weight and so is the same. What WILL change, however, is how deep in the water it floats. The upthrust is provided by the weight of the displaced volume of water, the volume of which depends upon the density of the water which depends upon the temperature and saltiness (amongst other things) of the water. As freshwater is less dense than [briny] sea water, it will require more volume for the same weight and so the ship will float deeper in freshwater than in [briny] sea water. This can be seen in the load lines on the "Plimsoll Line" where the Freshwater line is much higher than, say, the Winter North Atlantic line (the latter being more salty and colder, and so much more dense) meaning that for the same load, that the waterline in Freshwater will be much higher up the ship than in Winter North Atlantic (or alternatively, the ship will float much deeper in the Freshwater than the Winter North Atlantic).
What shapes the earth-?
water ______________ Basically, gravity shapes the earth. During the time that it was acquiring more and more mass from the disk of materials in its path, it reached a point where simply by the weight of its own components it began to collapse into a shape that was more and more sphere-like. This in fact is one of the requirements for a body to be considered a planet. In terms of erosion, water wind heat microorganisms plant and animal life all play a part in shaping certain aspects of the surface. But the fundamental shape of the earth is under the control of gravity.
Why is the mass of an object the same on the moon as it is on earth but the objects weight is different?
That is because Earth has more gravity. Weight = mass x gravity.
What does data redundancy mean?
Data redundancy: Sometime Data redundancy refers to in computer data storage, is a property of some disk arrays which provides fault tolerance, so that all or part of the data stored in the array can be recovered in the case of disk failure. The cost typically associated with providing this feature is a reduction of disk capacity available to the user, since the implementations require either a duplication of the entire data set, or an error-correcting code to be stored on the array.Redundancy is attained when the same data values are stored more than once in a table, or when the same values are stored in more than one table.One of the biggest disadvantages of data redundancy is that it increases the size of the database unnecessarily.
Which cylinder represents that greatest amount of freshwater on earth?
The cylinder representing the greatest amount of freshwater on Earth is the one that includes the water stored in glaciers and ice caps. This frozen freshwater accounts for about 68.7% of the total freshwater on Earth.
Is there more saltwater than freshwater on the earth?
There is much more saltwater than freshwater. All of the oceans are made up of saltwater for example.
More than two thirds of earth's fresh water is found in?
76% (more than two thirds) of Earth's freshwater is found in any ice on Earth. (ex. glaciers) 23% of freshwater is found in groundwater 12% of the groundwater is "shallow ground water" 11% of the groundwater is "deep ground water" 0.34% of Earth's freshwater is found in rivers, streams, and lakes 0.037% of freshwater is found in water vapor
How mush of the earth is covered by water?
More Than 70% but only 1% is freshwater
Do lakes and streams hold more than two thirds of earths freshwater?
oceans freshwater and lakes and streams cover 2/3 of earth
What is more plentiful groundwater or surface water?
Groundwater is generally more plentiful than surface water. It is estimated that about 30 times more freshwater is stored as groundwater compared to surface water. Groundwater is stored in underground aquifers and is replenished by precipitation and surface water sources.
Is there more salt water or freshwater?
Approximately 97% of Earth's water is salt water, found in oceans, seas, and saltwater lakes. Only about 3% of Earth's water is freshwater, found in rivers, lakes, groundwater, and glaciers.
Where is most of earth freshwater located?
In glaciers. There is more frozen fresh water than in all the lakes and streams. Glacial melting also causes the desalination of the ocean, which is a bad thing. so we want the fresh water to stay in the glaciers
Is there more nutrient in salt or freshwater?
Salt and freshwater are not nutrients.
Is tap water fresh water?
Springs are simply freshwater. But some of the fish, if any, in springs are salt and fresh water fish. Think of ponds and rivers and lakes. Those are all freshwater too. One more fact that I have to tell you is that water should be stored in a cool, dark, and dry place.
Can halophilic plants exist without salt?
Do halophilic plants require a salty soil? One study suggests that as a general rule even halophilic plants are more productive with regular freshwater flushing. What happens is that the salt is stored in tissues in the plants leaves (usually). stored not abosrbed or used
Does the Earth have more areas of water or more areas of land?
75% of the Earth is covered in water, so definitely water. If you counted all the water stored in ice-caps it would be even higher.
