Chapter 27, Problem 13RQ

To determine

The name and three types of plate boundaries.

Answer to Problem 13RQ

The three type plate boundaries are Divergent plate boundaries, Convergent plat boundaries and Transform plate boundaries.

Explanation of Solution

The first type of plate boundary is the divergent plate boundary. When two upward-moving convection currents in the mantle meet at the surface, then the boundary formed due to that meet is known as the divergent plate boundary. This meet gives rise to a tensional force that spreads the lithospheric plates apart.

The second type of plate boundary is the convergent plate boundary. Under the compressive stress, when two tectonic plates meet together or converge together, then the boundary formed is known as the convergent plate boundary.

The third type of plate boundary is the transform plate boundary. When two tectonic plates slide to each other at transform plate boundaries, then the type of boundary formed is known as the transform plate boundary. These types of plate boundaries are only found in ocean basins connecting offsets in mid-oceanic ridges.

Conclusion:

Therefore, the three type plate boundaries are Divergent plate boundaries, Convergent plat boundaries and Transform plate boundaries.
