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.
The hierarchical progression of levels of biological organization corresponds to and results from the history of the development of living organisms. The accepted view of the origin of life maintains that life evolved from organic molecules which were formed independently of living organisms.

In physics, the term conservation refers to something which doesn't change. This means that the variable in an equation which represents a conserved quantity is constant over time. It has the same value both before and after an event.
