Welcome to Science 11/4 • Get your Rock Outline/Chart out and answer questions 5-8. • Today’s Schedule • 1. Finish Rock Chart: Sedimentary Rocks • 2. Sedimentary Rocks Activities
Sedimentary Rock • What does sediment mean? • Sediment- small, solid pieces of material that come from rocks or living things. • What is a sedimentary rock? • Rock made of sediment that goes through a series of processes.
From Sediment to Rock • Weathering- the break down of rock by wind, water, ice, gravity, etc. • Erosion- running water, wind, or ice loosen and carry away fragments of rock. • Interactives . The Rock Cycle . How Rocks Change
From Sediment to Rock • Deposition- the process by which sediment settles out of the water or wind carrying it. • Observe how sediments are deposited.
From Sediment to Rock • Compaction- the process that presses sediments together.
From Sediment to Rock • Cementation- process by which sediments are glued together and hardened to form rock.. • Interactives . The Rock Cycle . How Rocks Change
Sedimentary Activities • 1. You can work on the Rock Y-Chart. • 2. You can write a story about a rock that goes through the sedimentary process. • 3. You can make a sedimentary rock.
Sedimentary Rock Story • Iggy the igneous rock was born on top of a volcano when it erupted. Iggy began to become sediment through many years of facing the wind and rain at the top of the volcano. Erosion washed iggy down from the volcano into a river where he was eventually deposited in the Pacific Ocean. Iggy was feeling the pressure and began to compact. After thousands of years, Iggy, now at the ripe old age of 10,000, cemented and turned into a sedimentary rock.
