This term the grade 5’s are learning about natural disasters. The thing I’m most interested in is tsunamis. A fact I have learnt is that when an undersea earthquake or other major disturbance causes a section of the ocean floor to suddenly rise or sink, the mass of water above the affected area also rises or sinks. This unexpected movement of the water creates a series of powerful waves. There was a terrible tsunami in Japan a few weeks ag0 it was very sad that so many people lost their lives and their homes.
