Question

How does the age of seafloor basaltic rocks change with respect to the ocean ridges? They are youngest close to the ridges, They are oldest close to the ridges, The seafloor is comprised of granitic rock not basaltic. There is no pattern to the age of seafloor basaltic rocks..​

Answer 1

They are youngest close to the ridges,

Step-by-step explanation:

At the ocean ridges, there is divergence at their margins.

Therefore, new materials upwell from the mantle below to the surface.

• The basaltic materials cools and solidifies at the margin.
• This action forces the old lithosphere backwards as the plate pulls away.
• At the margin of the ridge, the rocks are younger.
• Away from the margin, the crust begins to grow older.

So, at the margin the age of the rocks are more younger than those away from the margin.
