Sedimentary Rock 12/4/ pgs IN: Describe how igneous rock is classified. Put your DRW on the box
I GNEOUS R OCK - T EXTURE AND COMPOSITION Texture – where the magma cools Intrusive – coarse grained Extrusive – fine grained
I GNEOUS R OCK - T EXTURE AND COMPOSITION Composition – color Felsic – light colored less dense Mafic – dark colored more dense
H OW DOES SEDIMENTARY ROCK FORM ? 1. Weathering and erosion creates sediment followed by, 2. compaction and cementation forms sedimentary rock.
W EATHERING Wind, water, ice, sunlight, and gravity all cause rock to weather into fragments. These small fragments are called sediment.
E ROSION Sediments are transported from one place to another. rivers
C OMPACTION The layers eventually become compacted.
C EMENTATION Dissolved minerals separate out of the water to form a natural glue that binds the sediments together.
Strata - the layers of sedimentary rock that form from the deposition of sediment.
S EDIMENTARY ROCK Form at or near the Earth’s surface. Their physical features tell part of Earth’s history.
S TRATA Sometimes records the motion of wind and water waves.
C OMPOSITION 1. Clastic 2. Chemical 3. Organic
C LASTIC SEDIMENTARY ROCK Forms when rock or mineral fragments, called clasts, stick together. sandstone Names of clastic sedimentary rock are based on grain size.
C HEMICAL SEDIMENTARY ROCK Forms when minerals crystallize out of a solution, such as sea water, to become rock. limestone
O RGANIC SEDIMENTARY ROCK Forms from the remains of organisms. fossiliferous limestone
T EXTURE Stratification - the layering of rock. Strata differ from one another depending on the kind, size, and color of their sediment.
C ONGLOMERATE Sedimentary rock that resembles concrete. Clastic Coarse-grained
S ANDSTONE Sedimentary rock formed from sand. Clastic Coarse-grained
S HALE Sedimentary rock also known as mudstone. Clastic Fine-grained
F OSSILIFEROUS L IMESTONE Sedimentary rock made from shells and coral. Organic
C OAL Sedimentary rock made from fossilized carbon Organic
OUT: Describe the process by which clastic sedimentary rock forms.
Rocks Chapter 4. What is a rock? Rock Mixture of minerals, rock fragments, volcanic glass, organic material, or other natural materials.
Answer the following questions about the picture to the right: How and where did this rock cool? What minerals might it be made up of? Make sure to explain.
Sedimentary Rocks Rocks made of bits & pieces of other rocks.

Chapter 4 - Rocks What can be learned by studying rocks… We can learn mo better about earth. So what is a rock??? Its a mixture of 1 or more minerals.
What is a Rock? Naturally-occurring mixtures of minerals, mineraloids (no crystals), or organic matter. Naturally-occurring mixtures of minerals, mineraloids.
Chapter Introduction How do the three main types of rocks form?

Ch 3 Notes Mr. Russo Beaumont High School. Ch 3 Vocab Matrix – Pg 30 Igneous Rock Lava Magma Weathering Sediments Sedimentary Rock Metamorphic Rock Intrusive.
Chapter 3 Rocks. Rock – any solid mass of mineral or mineral-like matter that occurs naturally as part of our planet –Usually solid mixtures of minerals.
What is a rock?. A rock is a naturally occurring solid mixture of one or more minerals or organic matter.
SEDIMENTARY ROCKS. Classification of Rocks 4 Rocks are aggregates of minerals. Geologists divide rocks into three groups: igneous, metamorphic, and sedimentary.
