EARTH’S LAYERS ARIZONA STATE SCIENCE STANDARDS: GRADE LEVEL 7 Strand 6: Earth and Space Science Concept 2: Earth’s Processes and Systems • Understand the processes acting on the Earth and their interaction with the Earth systems. PO 3. Analyze the evidence that lithospheric plate movements occur. PO 4. Explain lithospheric plate movement as a result of convection.
EARTH’S LAYERS DAILY OBJECTIVE: Students will be able to recognize and name layers of the Earth
TWO TYPES OF EVIDENCE: Collecting data by measuring seismic waves created by earthquakes from around the world.
TWO TYPES OF EVIDENCE: Collecting data by examining rock samples driven to the surface of the Earth.
LAYERS OF THE EARTH: CRUST v. Layer of rock that form Earth’s outer skin v. Thinnest layer of Earth, and least dense v. Includes land forms, soil, water, all life on earth
TYPES OF CRUST ²Oceanic: All of the ocean floors ²Continental: Includes all continents and islands
LAYERS OF THE EARTH: MANTLE v Layer of hot, solid rock just below the Earth’s crust v Thickest layer of Earth, and more dense than the crust v Two kinds: v. Lithosphere v. Asthenosphere
TYPES OF MANTLE Lithosphere ²Rigid layer of the upper most part of the mantle and lower part of the crust ²Made up of large and small slabs of tectonic plates
TYPES OF MANTLE Asthenosphere ²Under the lithosphere ²Softer and hotter rock is located here ²Flows slowly like hot tar
LAYERS OF THE EARTH: OUTER CORE ØComposed of liquid iron and nickel ØTemperature, pressure, and density here are lower than in the inner core; that is why this layer is a liquid
LAYERS OF THE EARTH: INNER CORE Ø Solid layer of nickel and iron Ø Highest temperature, pressure, and density
