The water would keep the magma at the same temperature restricting it from getting hotter keeping the temperature at melting point but not enough to turn into a flowing liquid
<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.
I'd have to say the Southern Eurasian plate and the Western part of "our" North American plate (mainly around California) both have a lot of above sea level activity. The most activity below or right at sea level would possibly be the Philippines plate.
