The correct answer is - D. volcanic eruptions.
In recent studies and research about the water on our planet and how it came to be, the scientists managed to find new evidence that suggest that not only the comets and asteroids contributed to the existence of water on our planet, but also the volcanoes.
The volcanoes are actually releasing into the atmosphere the material from the deeper part of the Earth, the mantle layer. The mantle layer, as it turns out, has water in its rocks, so through the volcanic eruptions, that were much more and much bigger in the distant past, that water got released into the atmosphere. From the atmosphere, that water was falling on the surface, thus contributing to the creation of the first oceans on Earth.
Answer:
The mineral zircon adds three more fundamental advantages to uranium–lead dating.
Explanation:
Answer:
The movements involved in plate tectonics acted like a giant conveyor belt for earths lithosphere and the Mid ocean ridges occur where mantle material rises upward, creating new seafloor crust and pushing plates apart.
Explanation:
How does this action explain the differences between seafloor crust and continental crust?
The movements involved in plate tectonics acted like a giant conveyor belt for earths lithosphere and the Mid ocean ridges occur where mantle material rises upward, creating new seafloor crust and pushing plates apart.
Main differences between sea floor crust and continental crusti is that oceanic crust and continental crust are less dense than the mantle, but sea floor crust is denser than continental crust. It also noticed that subduction occurs at ocean trenches, where dense seafloor crust pushes under less dense continental crust, thereby returning seafloor crust to the mantle. The subducting seafloor crust may partially melt, with lower density material melting first and erupting from volcanoes as new continental crust.
