How does the observed change in sea-floor age support the theory of sea-floor spreading?

Answer:

The seafloor is younger at the mid-ocean ridge, and as it gets further away from it is older and older.

Explanation:

The seafloor and its characteristics is one of the best evidence when it comes to the theory of plate tectonics. This was first noticed by Alfred Wegener and later by any other scienticsts that have been interested in this theory. Basically, the evidence lies in the fact that the seafloor is the youngest at the active mid-ocean ridge, and the further it is from it it gets older and older, with the oldest seafloor being found at the subduction zones.

The reason for this is the manner in which the seafloor forms. The high activity in the mantle below manages to break the crust of a preexisting plate and divide it. It pushes enormous amouns of magma toward the surface constantly for millions of years. The magma quickly solidifies and creates new seafloor as it gets in touch with the water. The magma that comes through pushes the already consolidated one aside and the process goes on for millions of years.

How much more energy releases from a magnitude 2 earthquake compared with a magnitude 1 earthquake?
ch4aika [34]

Answer: Earthquake refers to the sudden shaking of the earth due to the release of energy by the seismic ways in the earth's interior. An earthquake of magnitude 2 is exactly ten times bigger, as well as about 31-33 times stronger than that of magnitude 1 .

Richter scale is used to measure magnitude of an earthquake, that means how much energy has been released due to the release of seismic waves.

Would happen if we did not experience gravity here on earth or within our solar system?
Wittaler [7]

Answer:

Weightlessness.

A breakdown in the Universe as objects would move out of their orbits.

Muscle athropy and osteoporosis

Explanation:

All objects would move freely in space and also on earth. Due to this loss of mass, the human body's bones and muscles will have no weight on them hence leading to them shrinking. On a larger scale there will be no orbits to hold planets and other celestial bodies in place.
