Good luck honey! you got this :) and if you fail i’m still proud of you
The Drilling sample of the Seafloor spreading theory helped in determining rock ages on the floor of ocean.
Explanation:
The formation of crusts of ocean by the process of volcanic eruptions in the ridges of the middle ocean is the theory of seafloor spreading proposed by Hammond Hess. The movement of tectonic plates continuously forms sea floors through spreading of seafloor. The several evidences in support of this theory has been seen, of which some are – molten material eruptions, magnetic stripes in rocks and rock ages.
The drilling evidence is the final one that was proved by taking samples of rock by drilling in ocean and by bringing them with pipes. The observation of these rocks proved that older rocks were collected from farther ridges and youngers are found in the central ridges.
Answer:
Progenies of batch I would not be labeled by 35S; progenies of batch II would be labeled by 32P.
Explanation:
Answer:
Granite is formed when molten magma flows and cools underground.
Explanation:
Granite is an intrusive igneous rock, so it forms underground.
