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.
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 has more freshwater lakes rivers or groundwater?
groundwater has more freshwater than rivers and lakes
What contains more of Earth's water?
Water covers approximately 70% or more of the water on Earth. Salt water covers most of the surface on the earth's water supply. Amazingly only 3% of all water on earth is freshwater.
Is there more nutrient in salt or freshwater?
Salt and freshwater are not nutrients.
Is there more salt water or freshwater?
There is by far more saltwater in the world. The oceans of the world are saltwater, and by volume the oceans compose over ninety percent of Earth's water.
Which is a more cost efficient pool system saltwater or freshwater?
Freshwater
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.
Which cylinder represents that greatest amount of freshwater on earth?
Meaningless question. Try expressing your enquiry in a more helpful manner so respondents who know can tell you.
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
