Presentation transcript:

Warm-up 1. Name 4 Rock Textures. 2. Explain what is wrong with this sentence: “Rocks with a fine-grain texture have Large crystals because they form so quickly.”

“Sedimentary & Metamorphic” 3.3 & 3.4

Q:What is weathering? Erosion: –Getting rid of rock. –Weathering. Q:What is sediment? Deposition: –Deposit = “to leave” –Sediments are deposited according to size. –Smaller sediments travel longer distances

Observe: Weathering Erosion Sediment Deposition

Creating Sedimentary Rock 1.Compaction = squeezing sediments –Due to weight of layers 2.Cementation = sediments stick together. –dissolved minerals are deposited in the tiny spaces among the sediments.

What does this show?...

Classification of Sedimentary Rocks 1.Clastic: –Bits of rock/mineral 2.Chemical: –dissolved minerals precipitate (fall) from water solutions 3.Biochemical: –Smushed dead organisms.

Which type is this?...

COAL

History & Sedimentary Each layer of sedimentary rocks records a period of sedimentation Youngest = top ↑ Oldest = bottom ↓

Creation: Of Metamorphic! 1. Contact Metamorphism – –m–magma changes rock 2. Regional Metamorphism –H–Heat & Pressure –M–Mountain building

Contact Metamorphism Regional Metamorphism

Metamorphic!

Classification of Metamorphic Rocks Foliated: –Banded Nonfoliated: –No Bands
