what is divergent boundaries?

• Divergent boundaries are regions where tectonic plates slide past each other without creating new crust.
• Divergent boundaries are areas where tectonic plates sink into the mantle, causing earthquakes.
• Divergent boundaries are where tectonic plates collide and create mountains.
• Divergent boundaries are tectonic plate boundaries where plates move apart

Divergent boundaries cause what?

• Volcanic activity and the formation of new crust.
• Earthquakes and the destruction of existing crust.
• Formation of mountain ranges and deep ocean trenches.
• Subduction of tectonic plates and volcanic eruptions.
