1.1A Flashcards
What are Mid-Ocean Ridges?
The mid-ocean ridge is an extensive underwater mountain range resulting from the constantly altering tectonic plates, heat, and magma emitted from the earth’s core. They are formed due to the continuous spread of the oceanic lithosphere, the crust, and the upper mantle at the divergent plate boundaries due to convection currents that lift the ocean floor.
What is the Oceanic Fracture Zone (OFZ)?
A belt of activity through the oceans along the Mid-Ocean Ridges, coming ashore in Africa, the red sea, the dead sea rift and California.
What is the Continental Fracture Zone (CFZ)?
A belt of activity following the mountain ranges in Spain, via the Alps, to the Middle East, the Himalayas to the East indies and then circumscribing the Pacific.
