Great salt lake is not a Great Lake
Answer: The settlement of the Americas.
Explanation:
The settlement of the Americas is widely accepted to have begun when Paleolithic hunter-gatherers entered North America from the North Asian Mammoth steppe via the Beringia land bridge, which had formed between northeastern Siberia and western Alaska due to the lowering of sea level during the Last Glacial Maximum (26,000 to 19,000 years ago). These populations expanded south of the Laurentide Ice Sheet and spread rapidly throughout both North and South America, by 14,000 years ago. The earliest populations in the Americas, before roughly 10,000 years ago, are known as Paleo-Indians.
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 pressure is
1.4 million atmospheres.
