Natural hazards bingo 1. Select nine words from the list at the bottom of the page and write each one in a blank space in the grid below. 2. Listen as your teacher reads out some definitions. 3. When you hear the definition for one of the words on your bingo card, put a neat cross through the word. 4. Call out ‘Bingo!’ when you have either a horizontal line, a vertical line or a full house. plate boundary collision zone fault epicentre deep-sea trench magma lava volcano mid oceanic ridge focus aftershocks destructive margin active zone rift valley constructive margin foreshocks fold mountains conservative margin ©www.teachitgeography.co.uk 2012 17540 Page 1 of 2 Natural hazards bingo Teaching notes 1. Make sure that all students have selected nine words from the list provided and written one in each of the blank spaces on their bingo card. 2. Read out the definitions below at random, keeping a tally of those that you have used. 3. If the students think they have the word that matches the definition, then they should cross it through on their bingo card. The three winners are the first with a horizontal line, the first with a vertical line, and then the first with a full house. 4. Check that the words on the winner’s bingo card match the definitions that you have read out. Key term Definition focus The point beneath the Earth’s crust where an earthquake starts. epicentre The point on the ground above the focus of an earthquake where the vibration is greatest. fault A break in the rocks caused by movements in the Earth’s crust. fold mountains Mountains formed by huge pressures in the Earth’s crust which push the rocks upwards. foreshocks Small earthquake shocks which come before the main earthquake. They can help warn people of a forthcoming earthquake. collision zone The area where two continental plates move together and collide. active zone An area where two tectonic plates meet. Earthquakes and volcanoes occur here. lava Molten rock which flows onto the surface of the Earth from an erupting volcano. magma Molten rock formed deep beneath the surface of the Earth. constructive margin Where two plates move away from each other and magma rises to the surface to form new crust. destructive margin Where oceanic crust moves towards continental crust. Oceanic crust is heavier, so it sinks beneath the continental crust and is destroyed. conservative margin Where two plates move past each other. Crust is neither formed nor destroyed. mid oceanic ridge A long, narrow line of underwater mountains, formed in the centre of an ocean by volcanic activity. deep sea trench A deep trench or underwater valley formed where continental crust meets oceanic crust. volcano A place where magma reaches the Earth's surface. aftershocks One of a series of minor tremors or earthquakes which occur after the main earthquake. rift valley A large depression in the Earth's crust. This is formed when a very large block of land slips downwards between two parallel faults. ©www.teachitgeography.co.uk 2012 17540 Page 2 of 2
