Sculpting Earth’s Surface Rocks Cycle, Weathering, Mass Movement, Erosion, Transportation, Deposition, How Earth Works Honors Science Jodi Lock; Holicong Middle School Pearson Earth Science; 3. 1, 5. 3, 6. 2, p 208 -209 G 2

Warm up Look at the objects on your table. 1. How are they similar? 2. How are they different? 9/16/19

So. A ROCK IS • A naturally occurring, solid, mixture of one or more minerals and/or organic matter Rocks are • Classified into 3 groups based on how they are formed: • igneous, sedimentary, metamorphic

• Texture and composition are used to classify rocks • They indicate how the rock formed This Photo by Unknown Author is licensed under CC BY-SA-NC

2 Types of Forces Create Rocks Constructive Destructive • Builds something up or creates something new • Breaks something down or destroys something Can something be BOTH? How? Why?

The Rock Cycle The rock cycle shows that rocks continually change from one type to another The elements in rock are not created or destroyed - they are constantly recycled.

Igneous Rock Form when magma cools and hardens. Shiny and glasslike Holes and spaces if gas is trapped Basalt and Granite

What is the difference between magma and lava?

Sedimentary Rock Lithification of particles (sediment) Contain sand, pebbles, stones; only rock that may contain fossils Most have layers or strata

Sedimentary Processes 1. Weathering (breaking down rock) 2. Erosion (movement of sediments) 3. Deposition (collection of sediment) 4. Lithification (gluing together)

Metamorphic Rock Formed under the surface of the Earth by extreme heat and pressure Ribbon-like layers or maybe shiny crystals Slate, Marble

Metamorphism Think about CAKE BATTER in an oven… Formed by tremendous heat & pressure, and chemical reactions inside the crust. Formed from all three rock types.

Warm up. . . 9/18/19 • What is a chemical change? • What is a physical change? This Photo by Unknown Author is licensed under CC BY-SA-NC

Mechanical Weathering • Physical forces change the rock • No change in composition • Increases surface area of rock • Frost Wedging • Thermal Expansion • Exfoliation • Biological Activity

Chemical Weathering • Chemical forces change COMPOSITION or rock • Dissolution • Hydrolysis • Oxidation

Erosion • Wearing away AND movement of rock particles • 4 “Agents” of erosion Gravity Water Glaciers Wind

Deposition This Photo by Unknown Author is licensed under CC BY-SA • Weathered & eroded material is deposited someplace else • When moving water slows, particles settle This Photo by Unknown Author is licensed under CC BY-SA-NC This Photo by Unknown Author is licensed under CC BY-SA • Which particles will settle first? Why? ? This Photo by Unknown Author is licensed under CC BY-SA-NC
