Explain how the ages of the rocks on the ocean floor support the theory of seafloor spreading​
Dafna11 [192]

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.

What major factors affected earth's changing climates?
Flura [38]
I just had this answer but it hasn't been graded. I put 1. Meteor impacts, 2. volcanic gases and 5. Milankovitch cycles. I didn't put earthquakes because I wouldn't think it would affect the climate changing since they just affect ground movement.

Circulating through the body, antidiuretic hormone arrives at the ____________ of the kidney.
natka813 [3]
The antidiuretic hormone, otherwise called vasopressin is made in the region of the brain called hypothalamus. The cells of the hypothalamus excrete this hormone through the connection they have with the pituitary gland. From this gland, the hormone is released into the bloodstream and eventually comes down to kidneys, affecting the kidney tubules, making them conserve water by transporting them back to the bloodstream.
