Natural Disasters – Earthquakes

Year 6’s Topic this half term is Natural Disasters. The children have learned about the causes and effects of earthquakes, tsunamis and hurricanes.

Year 6, please watch the video we made last week about earthquakes. The video talks about 3 types of earthquake; please write a short description of each type below.

  1. In the video three types of earthquakes were mentioned:
    1.Divergent: Divergent earthquakes are when two tectonic plates are moving away from each other producing a rift. Active divergent earthquakes mostly occur in the oceanic plates
    2.Convergent:Convergent earthquakes are when two tectonic plates collide with each other. When the tectonic plates collide between continental places, it forms a mountain like the Himalayas.
    3.Transform:Transform earthquakes are where two plates slide past each other horizontally. Most of them occur in the oceans.

  2. Convergent
    A convergent earthquake is formed when one tectonic plate collides or is forced over another plate as it moves.
    A divergent earthquakes occur when two or more plates are forced away or apart from each other.Thus, a divergent earthquake is a boundary where two tectonic plates are moving away from one another.

    The final type of earthquake is one where the two plates slide against each other in a sideways motion. These boundaries between plates is referred to as transform earthquake.

  3. Different types of earthquakes

    During a convergent earthquake,one tectonic plate is forced over another plate,creating a continental collision. Sometimes,mountains are formed.

    During a divergent earthquake,two tectonic plates move away from each other,often forming a Rift zone.

    Transform earthquakes are quite different to the two other earthquakes. During a transform boundary earthquake,two tectonic plates slide against each other.

  4. A convergent earthquake is when one tetonic plate is forced over the other plate during movement creating a thrust fault.

    A divergent earthquake is when the plates are forced apart from each other,usually forming a Rift zone.This kind of earthquake is common in the ocean floors where new floors are created.

    Unlike divergent and convergent,transform plates slip by each other,this is also called a Strike-Slip.
