4.1 Rocks and the Rock Cycle
|
This investigation will help you to:
|
 |
- Observe a collection of rocks and describe characteristics that
aid in identifying and classifying rocks.
- Recognize why careful observations and accurate, clear descriptions
are important in scientific inquiry.
- Using common rocks as examples, explain how the three basic
types of rocks form (igneous, sedimentary, and metamorphic).
- Illustrate how matter and processes interact in an endless cycle
of matter, called the rock cycle, in the Earth system.
- Recognize which processes in the rock cycle can be observed
and which must be inferred.
- Understand that new techniques and tools provide new observations
to guide inquiry and new methods to gather data, thereby contributing
to the advance of science.
