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.
Answer: migrantes estão no caminho e não se sabe do estatus deles {exilados, fugitivos etc etc} e nem sempre sabemos o objetivo, ponto final ou destino deles. Imigrantes são pessoas que acabaram de chegar no país que lhes recebeu (expressao "imigrantes" descreve a perspectiva dos habitantes do pais que lhes recebeu). Emigrantes sao aqueles que abandonam o país (expressao "emigrantes" descreve a perspectiva do habitantes do país de origem).
Explanation: As três palavras tem significado diferente e sempre requerem compreensao. Migrante está no caminho, imigrantes está chegando ou já chegou, emigrante está abandonando o pais de origem.

The iron in the earth's core is solid due to high pressure.
At the center of the earth is solid inner core, whose size is two-thirds of moon's size mad made up primarily of iron. The temperature in this core is equal to that of the sun's surface at 5,700 degrees Celsius. But the tremendous pressure caused by gravity prevents the iron from becoming liquid.
Surrounding this is the outer core made of nickel and small quantities of other metals and these remain liquid because the pressure here is a bit lower.
