The Divergent plate Boundary*-*
A divergent plate boundary is a region where two of Earth’s tectonic
plates move away from each other, allowing magma from the mantle
to rise, cool, and form new crust. This process creates features such as
mid-ocean ridges, rift valleys, volcanoes, and shallow earthquakes.
Divergent boundaries are most common on the ocean floor, where
they cause seafloor spreading, as seen at the Mid-Atlantic Ridge,
but they can also occur on land, like in the East African Rift Valley,
where a new ocean may eventually form as the continent slowly splits
apart.
The Convergent plate Boundary ^-^
A convergent plate boundary happens where two tectonic plates
move toward each other, leading to one plate being forced beneath
the other in a process called subduction, or causing the crust to
crumple and form mountain ranges. This type of boundary is
associated with powerful earthquakes, volcanic activity, and
deep ocean trenches. Examples include the Himalayas, formed by
the collision of the Indian and Eurasian Plates, and the Mariana
Trench, where the Pacific Plate is subducting beneath the Mariana
Plate.
The Transform plate Boundary-_A transform plate boundary occurs where two tectonic plates slide
past each other horizontally, causing intense friction and frequent
earthquakes but little to no formation of new crust. The movement is
mostly side by side rather than vertical, so volcanoes are rare. These
boundaries often create fault lines, with the San Andreas Fault in
California being a well-known example.
