Answer:
oceanic crust sinks because it is denser and has higher specific gravity than the more silicon aluminum enriched continental crust. What drives substitution is convection and conduction in outer core of earth, that heat , only a small part of which is due radioactive isotopes, has to make it's way to Earth's surface by both conduction and convection. Iron and nickel o have the highest specific gravities of the 10 most common elements in the Milky Way Galaxy. This is why oceanic crust sinks and is subducted continental crust has to have a lot more force applied before it inks, because it doesn't want to sink.
<u>Answer:</u>
For example, the dinosaurs' fossils helped the scientists to learn about their habits, habitats, etc.
<u>Explanation:</u>
Scientists greatly depend upon existing biological evidences of extinct organisms in the form of 'fossils' to study the earlier life existed within the biosphere and the geosphere.
Fossil research allows researchers to learn a great deal not only about the organisms' live form and behaviour but also the Earth's geosphere and biosphere at that time. Specially, transitional fossils are more apt to study as they demonstrate the transitional states of a fossil between the ancestral type and the descendants' recent form.

Explanation:
Features that are typical for the divergent plate boundaries are:
- <em>ocean ridges;</em>
Underwater mountain chains that are very long and are marking the border of the plates.
- <em>formation of new crust;</em>
Since the crust is very weakened and loose, the high temperature, pressure, and magma, are able to penetrate it and create new crust.
- <em>intense volcanic activity;</em>
The high amount of magma penetrating from the mantle layer is causing intense volcanic activity, thus the creating on new crust, and underwater mountain chains.
