TRANSCRIPT
A naturally occurring
solid mixture of one
or more minerals and
organic matter.
• Composition – chemical make up of rock; can be minerals
or other materials.
• Texture – size, shape, and position of the grains that make up the rock.
• Rock Cycle- the continual process by which
new rock forms from old rock.
• Weathering - rocks broken into sediments
• Erosion - sediments moved
• Deposition - sediments dropped
Composition – chemical make up of rock; can
be minerals or other materials.
Texture – size, shape, and position of the grains that make up the rock.
Coarse grain
Fine Grain
Rock Cycle- the continual process by
which new rock forms from old rock.
Weathering - rocks broken into
sediments
Erosion - sediments moving
Deposition - sediments dropped
Made of: volcanic material
Intrusive – formed below Earth’s surface
(magma) Cools slowly, large crystals
Extrusive – formed above Earth’s surface
(Lava). Cools Fast, Small Crystals
Granite, obsidian, basalt
Made by: cooling magma/lava

Basalt Pumice
Obsidian
Made by: compaction & cementation
Made of: sediments Clastic: made of other rocks
Chemical: forms from water and dissolved minerals Organic: made of remains of living things
How are sedimentary rocks formed?
Look at the layers!

Made by: heat & pressure Made of: other rocks
Foliated: mineral grains are
layered
Non-foliated: mineral grains are
NOT layered
