Plate Tectonics and Continental Drift

Alfred Wegener, a German meteorologist and geophysicist, first proposed the theory of continental drift in the early 20th century.

Fossil records of similar species found on different continents, separated by oceans, provide strong evidence for continental drift.

Convection currents in the Earth's mantle cause the movement of the crustal plates, leading to continental drift.

Pangea was the supercontinent that existed approximately 200 million years ago, before it began to break apart and form the current continents.

South America and Africa were once connected, forming a supercontinent called Gondwana.

At a convergent boundary, two tectonic plates collide, causing one plate to slide beneath the other.

Ocean floor spreading is the process by which new oceanic crust is formed as tectonic plates move apart.

The collision between the Indian and Eurasian plates resulted in the formation of the Himalayas Mountains.

The Theory of Plate Tectonics explains the movement of tectonic plates and the geological processes associated with it.

North America and Antarctica were once connected, forming a supercontinent called Laurasia.

At a transform boundary, two tectonic plates move past each other horizontally, causing earthquakes and faulting.

Rift formation is the process by which tectonic plates move apart, creating new crustal material.

Australia and Antarctica were once connected, forming a supercontinent called Gondwana.

At a divergent boundary, two tectonic plates move away from each other, creating new crustal material.
