Using the Teachit Geography template, this sorting exercise provides a framework for investigating cause of, effect of and response to the Boscastle flood.
It is a warm and moist tropical maritime air mass.
Residents had little time to react. Sort statements to show these causes, effects and responses, e. This is so good. A line of convergence formed near the coast line, where air moving in flooe opposite directions collides, this helped to increase the rate of ascent and produced very heavy rain.

A large quantity of water arrived within a short space of time causing the rivers to overflow. Cars, walls and even bridges were washed away.
There is more about rainfall radar in the weather section of the Met Office website. Human Impacts There was a huge financial cost to the floods.
Buildings were smashed, especially in the main street where the river channel flows. The damage not only affected the residents, but also insurance companies.
