Question

What can you say about the ages of the oceanic rocks near the Mid-Atlantic ridge? Do the ages of oceanic rocks get older as you move away from the ridge?

Answer 1

Answer:

The newest, thinnest crust on Earth is located near the center of mid-ocean ridge—the actual site of seafloor spreading. The age, density, and thickness of oceanic crust increases with distance from the mid-ocean ridge. ... Eventually, older oceanic crust encounters a tectonic boundary with continental crust.

Answer 2

Age of the oceanic crust increases with the distance from the mid-ocean ridge. And as an eventual event, older oceanic crust encounters a tectonic boundary with continental crust.

Explanation:

• New and thin crusts on earth is located at the actual site of seafloor spreading.
• This location is near the centre of the mid-ocean ridge.
• Pushing new crust away from the ridge, newer crust comes to the surface.
• Spreading out of ocean crust spreads out causes enlarging of ocean.  
• The oldest crust is then found at the edges of ocean.
• Age, density and thickness of the oceanic crust increases with the distance from the mid-ocean ridge.
• Age of oldest oceanic crust is 120 million years approximately.

• Age of continental crust is 3.2 billion years approximately.
