Answer:
Continental crust is about 20 to 70 km thick and thus 70% of this submerged and oceanic crust being about 10 km thick is only 30 % submerged.
Explanation:
- As the hydrological crust is considered to be much denser than the oceanic crust hence at the subduction zones the crusts sink into the mantel and are beneath the lighter continental crust as the oceanic crust is much older than the continental crust. As the continental crust forms many layers and has a bulk composition and the average density is about 2.83 g/cm and has a thickness of about 7 to 10 km.
Answer:
Yes, it does.
Explanation:
All of the continents that are seperate today were in the form of a single giant continent up until approximately 175 million years ago.
They drifted apart in time because of the molten lava that is constantly flowing right underneath the earth's hardened shell. Also, archeological discoveries that indicate the same species of animals/plants lived on different continents such as Europe and America long before humans or intercontinental travel were around.
I hope this answer helps.
Answer:
What these stars most have in common is that they are in hydrostatic equilibrium during the main sequence.
Explanation:
These stars are quite diverse and cover a wide spectrum of size and brightness since they are the most numerous group of stars in the entire universe.
A main sequence star:
- has not yet consumed all the hydrogen in its core
- can be yellow, white or blue but not yet a dwarf star
Therefore, 18 gram atoms hydrogen are present in dilute acid. Hope this helps :)
