The longest mountain chain in the world, the mid-Atlantic ridge, was produced by which boundary?
A
divergent
B
allegiant
C
convergent
D
transform
Explanation: 

Detailed explanation-1: -The correct answer is the Divergent plate boundary. The mid-Atlantic ridge: The mid-ocean ridge systems are the largest geological features on the planet. The Mid-Atlantic Ridge (MAR) is a mostly underwater mountain range in the Atlantic Ocean that runs 333km south of the North Pole-to subantarctic Bouvet Island.

Detailed explanation-2: -What type of plate boundary is the Mid-Atlantic Ridge? The Mid-Atlantic Ridge is a divergent plate boundary line. The features at the ridge are the result of convection currents within Earth dragging the North American and Eurasian Plates apart from each other.

Detailed explanation-3: -The Mid-Atlantic Ridge is an example of divergent plate boundaries. When two plates come together, it is known as a convergent boundary.

Detailed explanation-4: -The Mid-Atlantic Ridge (MAR) is known as a mid-ocean ridge, an underwater mountain system formed by plate tectonics. It is the result of a divergent plate boundary that runs from 87° N – about 333 km (207 mi) south of the North Pole – to 54 °S, just north of the coast of Antarctica.

Detailed explanation-5: -As the plates are pulling away, magma, from a dozen kilometers below the ocean floor, rises to the surface, forming new seafloor. In this process massive volcanic events give rise to large structures, over time, which constitutes the very ridge, plateaus, such as the Azores, islands and seamounts.
