Where does water come from and where does it go?
Water on Earth cycles from the oceans, where it evaporates from the surface, into the atmosphere, forms clouds, falls onto the land as rain, travels through wetlands, rivers, lakes and underground then returns to the ocean — collectively known as the hydrologic cycle.
Where does the water supply in your house come from?
Surface water and groundwater. Surface water and groundwater are both important sources for community water supply needs. Groundwater is a common source for single homes and small towns, and rivers and lakes are the usual sources for large cities.
Where do we get water from answer?
Answer. The main sources of water are surface water, groundwater and rainwater.
How do we get water?
Your drinking water comes from natural sources that are either groundwater or surface water. Groundwater comes from rain and snow that seeps into the ground. The water gets stored in open spaces and pores or in layers of sand and gravel known as aquifers. We use water wells or springs to harvest this groundwater.
What is the best source of water?
10 water-rich foods that will help you stay hydrated
- Cucumber, 96% water. Cucumbers are made up of 96% water – that’s the highest water content of any food.
- Tomatoes, 95% water. Tomatoes are made up of 95% water.
- Spinach, 93% water.
- Broccoli, 90% water.
- Brussel sprouts, 88% water.
- Oranges, 86% water.
- Apples, 85% water.
Can we make new water?
It’s just two hydrogen atoms and an oxygen atom thrown together; how hard can it be? The answer: very. Just mixing hydrogen and oxygen together doesn’t make water – to join them together you need energy.
Can water be created by man?
Theoretically, this is possible, but it would be an extremely dangerous process, too. To create water, oxygen and hydrogen atoms must be present. Mixing them together doesn’t help; you’re still left with just separate hydrogen and oxygen atoms.
How old is the water we drink?
A fascinating new study suggests that some of the water molecules we drink and bathe in are way old — as in more than 4.6 billion years old.
Do we drink dinosaur water?
As far as we know, new water hasn’t formed either. That means there’s a very high chance the water in your glass is what thirsty dinosaurs were gulping about 65 million years ago. It’s possible that you could drink the same water as a stegosaurus or a T-Rex because of the way water circulates around our planet.
What is the oldest drinking water in the world?
A scientists takes a sample of water from a mine deep underground in Ontario, Canada. The water turned out to be 2.6 billion years old, the oldest known water on Earth.
Is water older than the sun?
As much as half of the water in Earth’s oceans could be older than the Sun, a study has found. If most of the original water molecules were broken up, water would have had to reform in the early Solar System. …
Is the sun older than the moon?
A new study of Apollo lunar rocks suggests that the moon is older than anyone believed. The moon, researchers now say, likely formed about 50 million years after the solar system did, which is much earlier than the previous estimate of 150 million years after solar-system formation.
Is there any water on the sun?
Researchers Confirm that Water Exists On The Sun. In their 1995 study, the team recorded evidence of water — not in liquid form because the sun is too hot, but as vapor or steam — in dark sunspots. The scientists compared the laboratory infrared spectrum of hot water with that of a sunspot.
How far back can we see in the universe?
30 billion light-years
What is the oldest star in the universe?
Can a black hole kill you?
The point at which tidal forces destroy an object or kill a person will depend on the black hole’s size. For small black holes whose Schwarzschild radius is much closer to the singularity, the tidal forces would kill even before the astronaut reaches the event horizon.
How old is a black hole?
This 13-Billion-Year-Old Supermassive Black Hole Is the Oldest Ever Found.
Does time exist in a black hole?
For outside observers, a black hole is one solidary element, and there is no proper time inside the black hole, but there is only the observed coordinate time according to our spacetime coordinates.
What happens to time inside a black hole?
Near a black hole, the slowing of time is extreme. From the viewpoint of an observer outside the black hole, time stops. For example, an object falling into the hole would appear frozen in time at the edge of the hole. Inside a black hole is where the real mystery lies.
Can we go back in time?
The Short Answer: Although humans can’t hop into a time machine and go back in time, we do know that clocks on airplanes and satellites travel at a different speed than those on Earth. However, when we think of the phrase “time travel,” we are usually thinking of traveling faster than 1 second per second.
Do wormholes exist?
Wormholes are shortcuts in spacetime, popular with science fiction authors and movie directors. They’ve never been seen, but according to Einstein’s general theory of relativity, they might exist.
