How relevant is the continental drift theory?

Answer 1

It is the theory that continents are connected to the lithosphere, and whenever the lithosphere moves, so do the continents. Also, continents collide, seperate, and grind past each other at boundaries known as Transform Fault Boundaries( Plates grinding past each other), Convergent Boundaries(colliding plates), and Divergent Boundaries(Plates separating). At Convergent Boundaries, either the oceanic plate(if there is one) goes under the other plate and melts in the lithosphere, or 2 land plates collide and create mountains. At Divergent Boundaries, underwater, a space forms called a rift. Above water on land, volcanoes form, no matter what way the plates move. At Convergent Boundaries underwater, mid-ocean ridges form. Above on land, mountains form. At Transform Fault Boundaries, plates grinding past each other usually don't create volcanoes. They create earthquakes.

Answer 2

Although the continental drift theory was proven wrong (The continents do not move independent of oceanic crust), the idea that the continents were once joined and slowly moved apart is now accepted by geologists.

Answer 3

Continental drift occurs everywhere. What causes the "drift" is convection currents within the mantle, which is not directly observable. However, deep-sea trenches where subduction occurs and divergent plate boundaries where new oceanic crust is made show how seafloor spreading works.

Answer 4

The continental drift theory is highly relevant as it explains how Earth's continents have moved over time due to plate tectonics. This theory helps us understand the distribution of landmasses, geological processes, and the formation of Natural Resources. It continues to be supported by geological evidence and has shaped our understanding of Earth's history and evolution.
