ES2 CONSTRUCTING A SCALE MODEL OF EARTH'S LAYERS ...

Procedure B – Tabulating DataComplete the Properties of Earth’s Layers Data Table. It is on the back side of the Scale Model Drawing.Use your textbook to find the required information about each layer. Most of the information is in Chapter11 on page 309.(a) Name of Layer (already entered on chart)(b) Thickness of Layer – for crust, do NOT list “65 km”; give a range of thicknesses.(c) State of Matter – is the layer solid or liquid? For the mantle, write “solid, parts weak rock that canflow”(d) Composition – list the names of the major elements in each layer(e) Average Density – use these values: Inner Core 12.7-13.0 g/cm 3 ; Outer Core 9.9-12.2 g/cm 3 ;Mantle 3.3-5.5 g/cm 3 ; Crust – list two types: Ocean crust (Basalt) 3.1 g/cm 3 and Continental crust(Granite) 2.7 g/cm 3 .(f) Temperature Range and (g) Miscellaneous Notes – we will fill in these columns in class.Questions – Use your scale model, data table, and text to answer the following questions. IN SOMECASES, YOU WILL NEED TO LOOK UP INFORMATION IN YOUR TEXTBOOK.1. Describe the overall pattern of densities of Earth’s layers, beginning at Earth’s surface.2. Look up the term “Mohorovicic discontinuity” in the textbook – use the Index to find the page number.The nickname for this layer is the “MOHO”. What is the MOHO and where is it located?TRACE the “MOHO” on your scale model diagram and LABEL it.3. Which layer of Earth’s interior is the thickest?4. Which layer of Earth is thinnest?5. Look up the terms lithosphere and asthenosphere in your textbook. (Use the Index to find the pagenumbers.) Define each in the space below. Include the names of the layers in which each is located.lithosphereLocated in which layer(s)?asthenosphereLocated in which layer(s)?Make an inference: Which zone, the lithosphere or the asthenosphere, is made of denser rock? Howcan you tell?6. How is the Outer Core different from the Inner Core?7. Make some inferences about the following characteristics.The deeper you go into Earth’s interior, the PRESSURE will: (circle one)increase decrease stay the sameThe deeper you go into Earth’s interior, the TEMPERATURE will: (circle one)increase decrease stay the same
