a) Differentiate between extension boundaries and compression boundaries.
b) Give two ways in which earthquakes can be predicted

Answer Text:
a) Extension boundaries are zones where tectonic planets diverge or move away from each other. Space may be created and magma fill the space found in between. While compressional
boundaries are zones where tectonic plates moves towards each other. There is thus destruction of materials found at the edges
b) Use of change of velocity of seismic waves
- Use of exotic pre-quake signals.
