In this set of materials, the reading passage tells us about the three types of rock, and the listening passage explains the additional usage of sedimentary rock, which is describing as a third rock in the reading passage.
The reading passage informs us about the characteristics of the three rocks. The most common rock is Igneous rock which means fire. The example of it is granite. By cooling and solidification of lava, igneous rock will be formed, and this makes up approximately 64.7% of the earth’s crust. The second common one is Sedimentary rocks, which means sit, and the representative example is Sandstone. Sedimentary rock is composed of a little particle of rock and other elements settling into layer, and about 7.9% of the earth’s crust
