Which concepts are described in the theory proposed by hess? check all that apply. continents are moving. ocean floor is created. ocean floor is destroyed. trenches are sites of seafloor spreading. mid-ocean ridges are sites of seafloor spreading.

Answer

Correct Answers are Mid ocean ridges are sites of seafloor spreading

and Younger ocean floor is created

Explanation

Harry H. Hess was a geophysicist. In 1960, he proposed a  theory which is later became known as 'Sea Floor Spreading'. Hess discovered that the oceans were shallower in the middle.  According to Hess, From Earth’s mantle molten material is  continuously flowing along the crests of the mid-ocean ridges.

As soon as temperature of  magma decreases, it is pushed away from the flanks of the ridges. Due to this process a younger ocean floor is created.

Hess also proposed that due to light weight of continental crust, it didn't sink back into the deep earth at trenches as did the oceanic crust.

Right answer is (Mid sea edges are destinations of ocean bottom spreading) . Also, younger sea floor is made .

Harry H. Hess was a geophysicist. In 1960, he proposed a hypothesis which is later ended up known as 'Ocean bottom Spreading'. Hess found that the seas were shallower in the center. As indicated by Hess, From Earth's mantle liquid material is ceaselessly streaming along the peaks of the mid-sea edges.  

When temperature of magma diminishes, it is pushed far from the flanks of the edges. Because of this procedure a more youthful sea depths is made.  

Hess likewise suggested that because of light load of mainland outside, it didn't sink once again into the profound earth at channels as did the maritime hull.

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement
