Takeaways

• 🌍 Earth's surface is predominantly covered by water, with oceans making up about 70% of the planet's surface.
• 💧 Water is essential for the continuation of life on Earth, and without it, life as we know it would not exist.
• 🔍 There are various theories about the origin of water on Earth, with most scientists believing that Earth was initially a dry, rocky planet.
• 🚀 The most popular scientific theory suggests that water first appeared on Earth in the form of large, water-rich asteroids.
• 🌌 Another theory posits that water has been present since the early formation of Earth, originating from the gas clouds that formed the solar system.
• 🌠 Some researchers believe that water on Earth was brought by comets during the early stages of its formation.
• 🧪 Researchers who believe water has been present since Earth's creation study meteorites and analyze their chemical compositions to find evidence supporting the origin of water on our planet.
• 🚀 The European Space Agency's unmanned spacecraft, Rosetta, was sent to land on comet 67P/Churyumov-Gerasimenko to study its composition, providing insights into the origin of water on Earth.
• 🌐 The composition of water found on Earth is similar to that found in asteroids, suggesting a common origin.
• 🔬 Despite ongoing research, there is no definitive answer yet as to whether water on Earth was present from the beginning or brought by comets and asteroids.
• 🌊 The mysteries of the ocean are vast, with only about 14% of the ocean floor explored, leaving much to be discovered about the underwater world.

Q & A

What is the importance of water for the continuation of life on Earth?

Water is an essential element for the continuation of life on Earth. Without water, life as we know it would not be possible.

What percentage of Earth's surface is covered by oceans?

Approximately 70% of Earth's surface is covered by oceans.

What is the percentage of water on Earth that is contained in the oceans?

Around 95% of all water on Earth is contained in the oceans.

What are the prevailing theories about the origin of water on Earth?

There are several theories about the origin of water on Earth, including the belief that water first appeared on Earth in the form of water-rich asteroids, or that it was present since the early formation of the Earth from the gas clouds that formed the solar system.

What is the role of comets in the theory of water's origin on Earth?

Some scientists believe that comets played a role in bringing water to Earth during its early formation.

What is the composition of water, and how does it relate to the water found on Earth?

Water is composed of oxygen and hydrogen. The water on Earth is believed to have formed from oxygen and hydrogen, and possibly deuterium.

What was the mission of the spacecraft Rosetta in relation to studying comets?

The spacecraft Rosetta was sent to land on the surface of comet 67P/Churyumov-Gerasimenko to study its composition and gather information about the origins of water and life on Earth.

What are isotopes, and how do they relate to the study of Earth's water?

Isotopes are variants of chemical elements that have the same number of protons but different numbers of neutrons. In the study of Earth's water, isotopes help scientists understand the composition and origin of water by comparing it to water found in other celestial bodies like asteroids.

Why is there more research conducted in space rather than in the oceans on Earth?

More research is conducted in space because conditions in space are more accessible and less hostile compared to the extreme pressures and darkness found at the depths of Earth's oceans.

What is the average depth of Earth's oceans, and how does it compare to the depth sunlight can penetrate?

The average depth of Earth's oceans is about 4,000 meters, while sunlight can only penetrate to a depth of approximately 900 meters.

What percentage of Earth's oceans have been explored, and what mysteries remain?

Only about 14% of Earth's oceans have been explored, leaving a vast amount of mysteries and unexplored areas beneath the water's surface.
