Bell work 10/24/2016 Get your comp. book! A Crust Label the parts of the Oreo earth from last week! B Mantle C Outer Core D Inner Core

Show what you know… Which is the outermost of the three layers that makeup the earth? Mantle C. Core Crust D. Lithosphere

Show what you know… The core is subdivided into the outer core, which is ______, and the inner core, which is ______. Liquid; solid C. Thick; thin Thin; thick D. Solid; liquid

Show what you know… Which of the following layers would have a composition of solid iron and nickel? 1 C. 3 2 D. 4

Test Goals: I can describe characteristics of the Earth’s three layers. I can recognize that plates move continually at a rate of centimeters per year. I can describe the relationship between plate movements and earthquakes, mountain building, volcanoes, and sea-floor spreading. I can evaluate the impact of man’s use of earth’s land, water, and atmospheric resources.

Today’s Goals: Identify the three layers of the earth. Describe characteristics of each of Earth’s layers. Explore plate tectonics. Justify scientific evidence that Pangaea once existed.

Have you ever looked at a map of the world and noticed how the coastlines on opposite sides of the oceans appear to fit together like the pieces of a puzzle? Video

Wegener’s Continental Drift Hypothesis

Wegener’s Continental Drift Hypothesis: Alfred Wegener—proposed the theory of continental drift Continental Drift—hypothesis that says continents once formed a single landmass, broke up, and drifted to their current locations Pangaea—huge, single continent that existed a long time ago

How did fossils provide evidence for Wegener’s hypothesis of continental drift?

Pangaea Current

What element would most likely be found in Layer C?

Lithosphere Continental Crust Asthenosphere Oceanic Crust Mantle B Mantle C Outer Core D Inner Core E

Tomorrow… Describe how mountains, volcanoes, and sea floor spreading occur on earth. Create images depicting convergent, divergent, and transform boundaries.
