The Changing Earth The aim of this presentation is to try and tell the story of rocks. It is easy to forget that the rocks are not permanent. They are made and broken down in a cycle. Through this PowerPoint presentation you should try to tell the story of rocks; the processes that form them and change them, some of their properties and what rocks can tell us about the earth. Use the questions on the slides that follow this one to create a presentation that tells this story. To access the necessary information, click on ‘info’. This takes you straight to a website. On each slide, delete the questions and substitute your answers. If these do not fit on one slide, change the font size. Make sure you answer in full sentences, and include the question in the answer. To print your work: Delete this slide and all the pictures (unless you use a colour printer, you will not be able to read the text) Click on ‘file’, ‘print preview’, ‘print what’ then ‘Handouts (6 slides per page)’ Ask permission and then print your fact sheet.

Eruptions info info What do volcanoes tell us about the inside of the Earth? Where do we find most of the world’s volcanoes? How can we know if a volcano is about to erupt? How fast does lava flow?How fast does lava flow?

Volcano info info 1.Explain the causes (how they are formed) and effects of volcanoes. 2.Explain how magma can emerge as volcanic flow. 3.Tell what kinds of volcanoes there are. 4.Find cool pictures that show lava flows.

Volcanoes info info List some good things about volcanoes

Sedimentary Rocks and Fossils info info What are fossils? Where are they found? How do fossils come to be in sedimentary rocks? info info Why are fossils useful?

Metamorphic Rock info info What is a metamorphic rock? How is slate formed? What is slate used for?

How Are Rocks Formed info & more info info info How are igneous rocks formed? How are sedimentary rocks formed? How are metamorphic rocks formed?

Rocks in the Graveyard info info Take a virtual tour of the graveyard In the graveyard you should be able to find an example of each of the three types of rock- igneous, sedimentary and metamorphic. List them. What properties of rock should you think about before using them in a graveyard?
