What are divergent boundaries.
300
When two plates with continental crust collide, what happens to the continental crust?
What is the crust pushes upwards, forming mountains.
300
The kind of deformation that leads to earthquakes are?
What is elastic deformation.
300
When you talk about the viscosity of lava, you are talking about;
