Question

The Mid-Atlantic ridge was discovered in the early 1950s. Which of these statements is/are true? A) There is a rift valley at the center of the ridge B) Mid-ocean ridges were recognized by Harry Hess as potential sites of seafloor spreading C) Earthquakes are located close to the center of the ridge D) A and C are both true E) A, B and C are all true

Answer 1

E

Step-by-step explanation:

The correct answer is:

E) A, B, and C are all true.

Here's why:

A) There is a rift valley at the center of the ridge:

This is true. The Mid-Atlantic Ridge does indeed have a rift valley at its center, which is where tectonic plates are moving apart, creating a gap and allowing magma to rise from the mantle to form new crust.

B) Mid-ocean ridges were recognized by Harry Hess as potential sites of seafloor spreading:

This is also true. Harry Hess was a geologist who proposed the theory of seafloor spreading in the early 1960s, which explained the formation of mid-ocean ridges and the movement of tectonic plates. His work was instrumental in our understanding of plate tectonics.

C) Earthquakes are located close to the center of the ridge:

This statement is true. Earthquakes often occur along the mid-ocean ridges, including the Mid-Atlantic Ridge, due to the movement of tectonic plates and the associated stress and strain in the Earth's crust.

So, all three statements A, B, and C are accurate, making option E the correct choice.
