Answer:
Oceans = > 97 percent of Earth's water.
Glaciers = > 70% of Earth's freshwater
River = > Powered by gravity
Groundwater = > 100 times more water than all rivers and lakes
97% of the water on Earth is not drinkable as it is salt-water in oceans.
Of the 3% that is freshwater, Glaciers make up about 70% which means that we don't have access to a significant amount of freshwater either.
Of the available freshwater to us, groundwater comprises 98% which enables it to be 100 times more than all rivers and lakes.
Rivers are powered by gravity in that they flow from areas of higher elevation to areas of lower elevation as gravity pulls it downwards.
The correct answer is - False.
The mechanization in the agriculture contributed to less people being involved in it, and that is because with the mechanization much less human labor is needed since the mechanization is doing the work for multiple people and animals, with the same or better efficiency, and also quicker and cheaper.
A theory is a system of rules and principles that can be applied to a wide variety of circumstances and has been successfully tested, but that is not universally accepted.
The intent of THEORY is a reasonable or scientifically satisfactory known principle or body of principles proposed to explain phenomena. The word often denotes an untested hunch or a guess without backing proof. But for scientists, a theory has closely the opposite meaning. A theory is a well-substantiated description of a facet of the real world that can incorporate rules, hypotheses, and facts.
The theory is a belief to clarify something, or a set of directing principles. Einstein's views about relativity are an example of the theory of relativity.
