How can we use the rock cycle model to describe the relationship between the processes and forces that create igneous, sedimentary, and metamorphic rocks?
Background Information
In grades 3 -7 you may remember analyzing and interpreting data from observations and measurements to describe and compare different Earth materials including rocks, minerals, and soil. You may also remember classifying each type of material based on its distinct physical properties.
Introduction
Learning the rock cycle and understanding the processes involved helps all of us. For example, soil forms, through the breakdown of rocks. We need soil to survive—imagine trying to grow vegetables without it. This is an immediate connection to the food chain. The rock cycle also gives scientists and engineers an idea on where energy sources (mainly fossil fuels, which are found only in sedimentary rock) and building materials such as marble or granite we rely on so much will most likely be located on Earth. We will see throughout this module how this cycle plays into just about every aspect of our lives.
Take a moment to think about something you would really like to learn this week about the rock cycle and how rocks can actually change from one type to another and add your question(s) to your science journal.
