Chemical weathering of rock Lesson 3

Objectives • Must recall that chemical weathering changes minerals in rocks • Should explain that igneous rock is weathered as it contains minerals • Could explain how features in limestone scenery are formed

What causes chemical weathering?

Construct NOT chaos in Science What I’m looking for - Your group to test the rocks and group them according to their reaction - If there is one you are unsure of you must discuss it and make a decision - Your group must be able to explain how you have come to that conclusion

You will be given……………. . • • • Samples of rock Weak acid Stopclock Beakers Samples of minerals

What you need to think about. . • What happens to the minerals when the acid is added? • How does this relate to the different types of rocks? • Does the way in which the rock is formed affect the way in which it is weatherered?
