KEY CONCEPTS
After the end of this module, you should have learned that:
MINERAL
a naturally occurring, inorganic, solid
material that has a fixed structure and
a definite chemical composition.
ROCKS
are naturally occcuring aggregates of
minerals, mineraloids, organic materials,
and pre existing rocks.
INTRODUCTION
•The most common rock-forming minerals are quartz,
feldspar, mica, pyroxene, amphibole, and olivine.
•The physical properties of minerals are color, streak, luster,
crystal habit, cleavage, fracture, hardness, and specific
gravity. These properties are used for mineral identification.
•Igneous rocks are formed from magma or lava and volcanic
fragments.
•Sedimentary rocks are formed when sediments are lithified.
•Metamorphic rocks are formed when rocks recrystaliizes due
to extreme teamperature and pressure conditions.
Get READY. SET yourself to #studymode. Here we GO !!!
If you close your eyes and taste different foods, you can usually figure out what the foods are. You can
identify foods by noting their properties, such as texture and flavor. Minerals also have properties that
you can use to identify them, and these properties usually determine the use of a mineral. Some
minerals that we used in our daily lives are the following, halite (salt) for cooking, graphite (pencil) for
writing, diamond and gold as jewelry, etc.
Remember that rocks can be divided into three groups based on how they were formed. Each main
group of rock can be divided into smaller groups which has specific features that make it different
from other kinds of rock. Geologists can learn how a rock formed by studying its features. The
combination of elements or compounds that make up a rock is the rock’s composition. The minerals
in a rock determine the rock’s composition which help geologists in classifying rocks. This is because
different minerals form under different conditions.
