Is Lake Michigan Natural
The lake's formation began 1.2 billion years ago when two tectonic plates moving in opposite directions left a giant scar—an event now known as the Midcontinent Rift. Less than 15,000 years ago, melting glaciers filled the giant basin, and Lake Michigan came to be. The lake's maximum depth is 925 feet.
How many percent of the world’s water surface does the Mediterranean Sea keep
The Mediterranean Sea occupies 1% of the world's water surface. But it is the dumping ground for 50% of all marine pollution. Almost sixteen countries regularly throw industrial wastes a few miles off shore.
Can I swim in Lake Michigan
The answer is, it depends. Under the right conditions, Lake Michigan is safe for swimming. But this lake can also present dangerous, even deadly, conditions for swimmers.
Do we drink Lake Michigan water
Lake Michigan, by volume, is the second largest Great Lake and the only one located totally within the United States. It serves as a source of drinking water, as a place for swimming and fishing, and as a scenic wonderland. Water from Lake Michigan enters the intake crib at depths of 20 to 30 feet.
Is 70% of the world ocean
The ocean covers more than 70 percent of the surface of our planet. It's hard to imagine, but about 97 percent of the Earth's water can be found in our ocean.
Which country holds 20% of the world’s freshwater
Canada
Canada has 20 percent of the planet's freshwater.

Is it safe to swim in Great Lakes
Great Lakes Waters Can Take A Savage Toll On Swimmers High winds and dangerous rip currents make swimming in the Great Lakes unpredictable, and sometimes deadly — most beaches have no lifeguards, and hundreds drown in the lakes each year.
Is Lake Erie safe to drink
The water that eventually ends up in your home starts about 3 miles out in Lake Erie before being treated to ensure it is safe to drink. Lake Erie is one of the five lakes that make up the Great Lakes. In total, the Great Lakes contain about 21% of the Earth's fresh water.
Is 95% of the ocean unexplored
More than eighty percent of our ocean is unmapped, unobserved, and unexplored. Much remains to be learned from exploring the mysteries of the deep.
Is 90% of the ocean unexplored
More than 80 percent of the ocean has never been mapped, explored, or even seen by humans. A far greater percentage of the surfaces of the moon and the planet Mars has been mapped and studied than of our own ocean floor. Although there is much more to learn, oceanographers have already made some amazing discoveries.
Where is 90% of the world’s freshwater
The Antarctic ice sheet
The Antarctic ice sheet holds about 90 percent of the fresh water that exists on the Earth's surface. The ice sheet covers approximately 8.7 million square miles. The Greenland ice sheet also contains large volumes of fresh water.
Where is about 70% of Earth’s freshwater found
Those ice sheets, which cover most of Greenland and Antarctica, only contain 2% of the world's total water supply, but a whopping 70% of the Earth's fresh water.
Can you boil lake water and drink it
If you don't have safe bottled water, you should boil your water to make it safe to drink. Boiling is the surest method to kill disease-causing germs, including viruses, bacteria, and parasites. adding a pinch of salt for each quart or liter of boiled water.
Why is Lake Superior so cold
Lake temperatures are largely driven by interactions with the atmosphere, so colder air temperatures lead to colder lake temperatures, according to the NOAA Great Lakes Environmental Research Laboratory (GLERL).
Why are the Great Lakes so deep
How the Great Lakes formed. During the last ice age, the mile-thick Laurentide ice sheet covered most of Canada and the northern contiguous United States. The massive weight and movement of this glacier gouged out the earth to form the lake basins. About 20,000 years ago, the climate warmed and the ice sheet retreated.
Can I swim in Lake Erie
Lake Erie is the smallest and shallowest of the Great Lakes, so chances are good that the temperature will be just right during the summer months. The lake hosts mostly sandy beaches, with easy access to the water and a chance to partake in boating, kayaking and swimming when local conditions allow.
Why is Lake Erie so clean
The major sources of phosphorus reductions were phosphorus outputs at wastewater plant discharges; eliminating phosphorous from laundry detergent; and no-till farming practices. Because of the phosphorus reductions, our Lake became much more clear and clean.
Did we discover 50% of the ocean
5. Less than 10% of the world's ocean, and less than 50% of U.S. waters, have been mapped. That's not very much coverage—and there's a lot to explore there! Humans know more about the physical and chemical properties of outer space than about planet Earth's deep ocean regions.
Is only 20% of the ocean explored
Though people have been exploring the ocean's surface for tens of thousands of years, only about 20% of the seafloor has been mapped, according to 2022 figures from the National Oceanic and Atmospheric Administration. Researchers often say that traveling to space is easier than plunging to the bottom of the ocean.
Is the ocean 5% explored
In fact, most of the waters remain unexplored, uncharted and unseen by our eyes. It might be shocking to find out, but only 5% of the ocean has been explored and charted by humans. The rest, especially its depths, are still unknown.
Where is 70% of the world’s freshwater
polar ice caps
More than 70 percent of the freshwater on earth is held along the polar ice caps.
Where is Earth’s freshest water
glaciers
Over 68 percent of the fresh water on Earth is found in icecaps and glaciers, and just over 30 percent is found in ground water. Only about 0.3 percent of our fresh water is found in the surface water of lakes, rivers, and swamps.
Is it safe to drink Rain water
Avoid using rainwater for drinking, cooking, brushing your teeth, or rinsing or watering plants that you intend to eat. Instead, use municipal tap water if it is available, or purchase bottled water for these purposes.
How did ancient humans drink water
Before, when people lived as hunters/ collectors, river water was applied for drinking water purposes. When people permanently stayed in one place for a long period of time, this was usually near a river or lake. When there were no rivers or lakes in an area, people used groundwater for drinking water purposes.
