  • Divergent Plate Boundary. Volcanic eruptions and shallow earthquakes are common where plates rip apart.
  • Convergent Plate Boundary.
  • Transform Plate Boundary.
  • Hotspot.

What are the 3 types of boundary?

Movement in narrow zones along plate boundaries causes most earthquakes. Most seismic activity occurs at three types of plate boundaries—divergent, convergent, and transform.

Which protocols are based on RFC?

RFC 9110, HTTP Semantics.

  • RFC 9111, HTTP Caching.
  • RFC 9112, HTTP/1.1.
