What type of plate boundary is characterized by tectonic plates moving away from each other?

  1. Divergent plate boundaries

  2. Convergent plate boundaries

  3. Transform plate boundaries

  4. Static plate boundaries

The correct answer is: Divergent plate boundaries

Divergent plate boundaries are characterized by tectonic plates that are moving away from each other. This movement occurs due to mantle convection and leads to the formation of new oceanic crust as magma rises to the surface at mid-ocean ridges. As the plates separate, they create a gap that allows molten rock to fill in, solidifying and expanding the seafloor. This process can result in geological features such as rift valleys and mid-ocean ridges and is crucial for understanding plate tectonics and the rock cycle. The creation of new crust at divergent boundaries is a fundamental aspect of the Earth's geology, contributing to the cycle of creation and destruction of lithospheric material.
