OBJECTIVE: Describe the origin of sedimentary rock.
INTROHave You ever tried to build a sand castle at the beach? Did you ever wonder where the sand came from?

Sedimentary Rock
• Sedimentary rock
• Strata
• Forms when sediments are compacted into a rock
• Most created at the bottom of oceans and lakes
• Can contain fossils of plants and animals
• Layers of rock

Sedimentary Rocks
• 3 Types:– Clastic Sedimentary Rock
• Made of fragments of rocks cemented together by minerals
• Course-grained (rough)• Medium-grained• Fine-grained (smooth)• Can easily record
ancient animal footprints, wave ripples, and even raindrops!

Sedimentary Rocks
• Chemical sedimentary rock
• Forms from solutions of dissolved minerals and water
• Dissolved material eventually crystallizes and forms minerals in the sedimentary rock
• Example:– Halite (salt) is found in
sedimentary rocks

Sedimentary Rocks
• Organic sedimentary rock
• Forms from the remains of plants and animals
• Example:– Limestone forms when
coral becomes compacted and cemented
– Coal forms from partially decomposed plants buried deep underneath sediments

OBJECTIVE: Describe the origin of sedimentary rock.
INTRO
Why do you think raindrop impressions are more likely to be preserved in fine-grained sedimentary rock rather than in course-grained sedimentary rock?
