Echo sounding

Explanation:

Harry Hess discovered the Mid-Atlantic spreading ridge by using echo sounding techniques.

  • Hess was a professor of Geology at Princeton University.
  • After the second world war, series of equipment used were deployed for scientific use.
  • The echo sounding was one of such devices that was adopted in mapping the sea floor.
  • It works by sending an echo to the ocean floor and determining the height to the base by their reflection.
  • From his works, he observed and noticed the mid-oceanic ridge.
  • This led to the formulation of the theory of sea floor spreading.

The reason why the lithospheric plates that compose the Earth's crust are constantly moving is A. The underlying mantle layer is molten where convection currents cause the movement of the lithospheric plates.

<h3>Why do plates move?</h3>

The earth's crust is made up of lithospheric plates that rest on the mantle which is molten as a result of the high temperatures of the core.

Convection currents in the mantle result in the plates moving as the currents come up from the core to heat up the mantle.

In conclusion, option A is correct.

A fossil recently discovered in Marlandia, a chain of islands, proves that a present-day reptile indigenous to Marlandia is desc
4vir4ik [10]

Answer:

E. The ancestral reptiles could not have survived long at sea.  

Explanation:

To get the answer to this question, the key is to focus on which option strengthens the conclusion of the scientists.

The scientists concluded that the sea level rise left at least a part of the Islands unsubmerged which may have caused some of the reptiles to survive. looking at the options, Option A weakens the conclusion of the scientist because if they can adapt, more of the reptiles would have survived in all the islands.

But option E strengthens the conclusion because since the ancestral reptiles could not survive long at sea, it therefore implies that there was at least a part of the island that was not submerged which helped in the survival of a population of the ancestral reptiles during the sea level rise.

Option B is irrelevant and option C is wrong because the statements clearly indicates that fossils shows that the current reptiles  can be traced to the ancestral reptiles on the Island.
