World Around Us - Natural Disasters
I hope that you enjoyed learning about the different types of volcanoes and how they are formed. This week you will be continuing to look at different types of volcanoes and the impact that they have on our environment.
Lesson 5 – Different types of volcanoes
Last week you looked at three different types of volcanoes – shield, composite and cinder cone. Shield volcanoes are bowl or shield – shaped in the middle. When they erupt, the lava is quite runny and it travels long distances down the side of the volcano before it cools down. Composite volcanoes are steep – sided volcanoes and are made up of lots of layers of volcanic rocks. They usually erupt in an explosive way because the magma in these volcanoes is quite sticky. Cinder cone volcanoes are circular or oval cones. They are made up of small fragments of lava, which are blown into the air through a single vent. When they cool down, they form rock around the vent.
In this lesson you will draw each of these volcanoes. You must find an example for each different type of volcano and write it below your diagram. For example, Mount St Helens is a composite volcano. You can use an iPad to help you with your research or you can use the ‘All About Volcanoes’ PowerPoint (slides 12 – 14). When you have completed this you are going to take a closer look at a composite volcano that erupted in the United States of America in 1980- Mount St Helens.
Step 1 – Watch the ‘Volcanoes 101’ YouTube video to remind you of some of the things you have learned about volcanoes so far
Step 2 – Open the ‘Diagrams of different types of volcanoes’ document
Step 3 – On a piece of paper copy the three diagrams and label them
Step 4 – Find an example of each different type of volcano and write it below your diagram (composite volcano – Mount St Helens). Use an iPad to help you or look at the ‘All About Volcanoes’ PowerPoint (slides 12 – 14).
Step 5 – Open and read the Mount St Helens link
Step 6 – At the bottom of the page you will see a section labelled ‘Activities’. Complete the ‘ten question quiz’.
Step 7 – Watch the ‘Mount St. Helens’ YouTube video
