About 500 million years after Earth formed
Scientists think that the continents were once part of a supercontinent called Pangaea that started breaking apart about 200 million years ago through the process of plate tectonics. This movement of the Earth's crustal plates continues to this day, causing the continents to drift apart.
Yes, the theory of continental drift suggests that the Earth's continents were once joined together in a single landmass called Pangaea. This theory is supported by evidence such as the matching shapes of continents, distribution of fossils, and geological similarities across continents.
They now think that the continents are moving because of tectonic plates and how they move, or drift, apart.
Alfred Wegener proposed the theory of continental drift, suggesting that the continents were once part of a supercontinent called Pangaea that broke apart and drifted to their current positions due to the movement of the Earth's tectonic plates. He suggested that the continents "plowed" through the oceanic crust as they moved.
Scientists study Earth's interior to better understand the planet's composition, structure, and dynamics. This helps in predicting natural disasters like earthquakes and volcanic eruptions, as well as in understanding processes like plate tectonics and magnetic field generation. Studying the Earth's interior also provides insights into the planet's history and evolution.
Earths crust extend deeper below the continents than below the oceans basins (or at least this is what I think).
200 million years
Im not a geologist but I would think that Europe and MAYBE Africa formed them. I reason that Europe formed them because Alps are from there, and Africa might have had some tectonic influence.
yeah i think they do!
I think you mean geologist. A geologist is a person who studies the earth's physical structure and substance, its history, and the processes that act on it.
I think it was Harrison Schmitt.
how do geologists think earths atmosphere is formed
Wikipedia has a good discussion on the many divergent areas that contributed to the theory of plate tectonics. Visit http://en.wikipedia.org/wiki/Tectonic_plate.
Plants consume water, in exchange we get oxygen. So the water levels are never the same I'd think.
It depends a lot on what the geologist is looking for, how much time they spend in the field or in the lab, and what they think is a "find".
London i think
Alfred Wegener noticed that the continents looked like they could fit together like a puzzle, particularly along their coastlines. This observation led him to propose the theory of continental drift, suggesting that the continents were once joined together in a supercontinent called Pangaea.
