Activity 4
Cycle of Rocks
Introduction
Rocks are constantly transformed, generated, and destroyed in a process called rock cycle. Depending on their origin of formation, rocks can be categorized into three types: igneous, sedimentary and
metamorphic
Content
Different rocks are found on Earth’s lithosphere. The continental crust is composed of lighter, thicker, and buoyant granitic rocks while the oceanic crust is composed of heavier basaltic rocks. Earth’s lithosphere is made primarily of rocks containing one or more minerals in them. Rocks are constantly transformed, generated, and destroyed in a process called rock cycle. Depending on their origin of formation, rocks can be categorized into three types: igneous, sedimentary and metamorphic. Along the way in this module, we will be classifying those rocks into their category through their characteristics and the processes on how they are formed
Objective
Identify and explain the processes involved in the rock cycle.
Materials
Pen and paper
Rock Cycle Flowchart
Procedure
1. Take a tour of the different types of rocks.
2. Write down the processes involved in transforming one rock to another.
Evaluation
Write down the different processes involve in each process.
Guide Questions
1.What are the processes involved in rock cycle?
2. How do the processes happened in the following transformations? Give examples of rocks that are transformed.
a. Igneous to sedimentary rocks
b. Sedimentary to metamorphic rocks
c. Metamorphic to igneous rock
