Introduction

The Mid-Atlantic Ridge (MAR) is a mid-ocean ridge, a divergent tectonic plate boundary located along the floor of the Atlantic Ocean, and part of the longest mountain range in the world.A ridge under the Atlantic Ocean was first inferred by Matthew Fontaine Maury in 1850. The ridge was discovered during the expedition of HMS Challenger in 1872.

How it Occurs

  • It is a divergent boundary which is a linear feature that exists between two tectonic plates that are moving away from each other. Divergent boundaries within continents initially produce rifts which produce rift valleys.
  • It is formed when two plates move apart from each other and the space that this creates is filled with new crustal material sourced from molten magma that forms below.
  • It is also a site of high geological activity as magma is pushed to the Earth's crust by the spreading of tectonic plates.

Where is it located?

Mid-Atlantic Ridge is an underwater formation extending from the northern edge of the Atlantic Basin to the southern edge.

Cultural Impact

Processes of water circulation�(created in the rock around the mid-ocean ridges)

Concentration of minerals in these areas

Form part of continents that we currently mine many minerals in these paleo-spreading centers

Environmental Impact

Current shape and configuration of the oceans has a controlling effect on ocean currents.

Ocean currents control how heat flows to the northern and southern latitudes

They control our climate as much or more than the atmospheric weather patterns.

Through this indirect relationship, mid- ocean ridges control atmospheric weather patterns as well.

Environmental Impact

They are responsible for the climate that we experience today as the current shape and configuration of the oceans has a controlling effect on ocean currents.

These ocean currents control how heat flows to the northern and southern latitudes, they control our climate as much or more than the atmospheric weather patterns.

In fact, the mid-ocean ridges, through this indirect relationship, control atmospheric weather patterns as well.

The origin of the Jet Stream is strongly controlled by the Himalayas, which are a product of spreading at mid-ocean ridges. The Jet Stream in the atmosphere, and the ocean current known as the Gulf Stream, as well as the Pacific currents, are responsible for most of the weather patterns in the northern hemisphere. Likewise the southern hemisphere has weather patterns created by the movement of energy through ocean currents and atmospheric currents, which are indirectly controlled by the movement of the tectonic plates driven by the mid-ocean spreading centers.
