The Isua BIF provides definitive 'ground truth' that surface water was indeed stable at 3800 Ma, however no 'boundary condition' can be defined by the Isua BIF. 2. Did water on Earth come from organic material from space? The oceans cover about 70 percent of the Earth's surface, and that about 97 percent of all water on and in the Earth is saline—there's a lot of salty water on our planet. Oceans are the storehouses of water nature uses to run the water cycle. Scientists. 6 How old is the water we drink?

Halley noted that of the small number of lakes in the world without ocean outlets (such as the Dead Sea and the Caspian Sea, see endorheic basin), most have high salt content. 10 Has water been discovered on Mars? 71% of the surface is covered in the oceans, more than half of which is deeper than 3,000 meters (9,800 ft), with an approximate total volume of 1.3 billion cu km (310 million cu mi).

As rain fell, chemicals in a hypothetical pool, warmed by the volcanic activity and energized by lightning, organized into proteins, lipids, and carbohydrates. 5 Why is the ocean blue? If the earth were smoothed out (that is, the mountains pressed down and the ocean basins lifted up), there is enough water in the oceans right now to cover the entire earth 8,000 feet deep (approximately 11/2 miles). When this happens, water is released. Where did the Earth's oceans come from? The origin of water on Earth is the subject of a body of research in the fields of planetary science, astronomy, and astrobiology. Comet Impact. Liquid water, which is necessary for life as we know it, continues to exist on the surface of Earth because the planet is . It forms in saline lakes and in marine environments where there is a LOT of evaporation of water. On Earth there is more ocean than land. A minor amount is tied up in ice. The rocky material that formed Earth in the first place contained some water. . Where did the water on Earth come from? So, where did the oceans come from? It orbits the earth. Upon reaching the ocean, these salts would be retained and concentrated as the process of evaporation (see Hydrologic cycle) removed the water. 4 Did early Earth have oceans?

Why does Earth have so much water relative to the other inner planets? According to the traditional theory about the evolutionary origins of humans, the ancestral ape when lacking food resources moved from quickly disappearing forested lands into the savanna.This gave our ancestors an upright posture and lead to brain development. Click again to see term . A young Jupiter's gravity could have sent them flying towards Earth. "Hence, the best model for the source of the oceans at the moment is a combination of water derived from comets and water that was caught up in the rocky body of the earth as it formed. The sources of the water are given in Genesis 7:11 as "the fountains of the great deep" and the "windows of heaven." The Fountains of the Great Deep A comet is a body made of rock and ice. Noah's Flood—Where did the water come from? The water in the asteroid belt is contained within minerals. So how did our planet end up with so much of this substance? This distributed water in large amounts to the earth, which eventually made up the oceans. Find out here how the water in the seas became salty. In fact, astronomers had begun to think that meteorites had to be responsible, even though their water content is much lower. The formation of the dust and clouds were the key elements in the formation of t… View the full answer The Formation of the Ocean This is an article from Curious Kids, a series for children.The Conversation is asking kids to send in questions they'd like an expert to answer. Although there's a long way to go, increased awareness and local action might just turn the tide on this global crisis, as photographer Zak Noyle explains. Most of Earth's water did come from .

All the liquid water above ground is surface water and it is a tiny blip of a much larger amount. 10 Has water been discovered on Mars? 2 What was the first ocean on Earth? It is interesting that up to 70 percent or more of what comes out of volcanoes today is water, often in the form of steam." "In their catastrophic plate tectonics model for the flood, Austin et al. have proposed that at the onset of the flood, the ocean floor rapidly lifted up to 6,500 feet (2,000 meters) due to an increase in temperature as . Oddly enough, young earth creationists tell us the water from Noah's Flood is in the oceans of today. Any water would actually stick around. Earth Sciences questions and answers. So the oceans are always being topped up in those areas, and then losing water in subduction zones, like off the coast of Alaska and South America, where it's dragging down water. 1 How Did The Oceans Form?

In recent years, many scientists have shifted from favouring a "primordial soup" in pools of water to hydrothermal vents deep in the ocean as the original source of . It even makes up about 60% of our bodies. The end result was that Earth had noble gases deep in its interior, with a lower deuterium-to-hydrogen ratio in its core than in its mantle and oceans. The mantle and the universe can be seen as the " deus ex machina " for all chemical . Scanning electron microscope image of a Baffin Island .
