Divergent Boundaries

• Definition: Divergent boundaries are areas where tectonic plates move apart from each other, leading to the formation of new crust.

Mid-Ocean Ridge

• Characteristics: The mid-ocean ridge is a continuous mountain range found on the ocean floor, marking the location of divergent boundaries.

• Location: Extends from the Arctic Ocean down to the Antarctic Ocean, indicating a global system of spreading centers.

• Formation of New Crust: As the tectonic plates diverge, magma rises from beneath the Earth's surface to fill the gap, creating new oceanic crust.

• Significance: This process is essential for the renewal of the ocean floor and contributes to geological activities such as earthquakes and volcanic eruptions.

Key Features

• Geophysical Changes: The diverging plates can cause the formation of rift valleys and fissures, along with hydrothermal vents that provide unique ecosystems.

• Age of the Ocean Floor: Generally, the closer to the mid-ocean ridge, the younger the ocean floor, as new material is continuously being created.
