Transcript Rock Cycle

The Rock Cycle
Learning Goal: I can identify common rock types and
the processes that formed them.
Importance of the Rock Cycle
• Different types of rocks give us different mineral
resources.
• Geologists know how to identify one rock type
from another.
• They know the type of rock and the structures
within each rock type.
• With this knowledge they can advise mining
companies where to search for specific mineral
deposits worth mining.
Key Terms
• Sediments: Rock that has been
broken down into pieces like
gravel and sand by the processes
of weathering and erosion.
• Weathering: The breaking down
of rock material by wind, rain,
ice and changing temperatures.
• Erosion: The transportation
(movement) of sediments from
one place to another by wind,
flowing water (rivers), glaciers,
etc.
