Layers of the Earth Quiz

Quiz yourself on the Earth's amazing layers: crust, mantle, core, and more!

How do scientists know what's inside the Earth? Volcano Data Earthquake Waves Drilling to the center Sort the layers into the correct categories. Identify which are the physical layers and which are the compositional layers. Physical Lithosphere Asthenosphere Tells if the layer is solid or liquid Compositional Crust Mantle Tells what the layer is composed of Move the terms into the appropriate layer of the Earth. Describe the elements, temperature, and state of matter of the composition of each of the layers of the Earth (inner core, -- outer core, -- mantle, -- crust). crust least dense layer thinnest layer the lithosphere contains this part and the upper mantle mantle top portion called the asthenosphere made of hot softened rock that flows like putty outer core liquid iron and nickle in between the mantle and inner core inner core hottest layer most dense solid iron and nickle As you travel from the surface of the Earth towards the inner core, the density, temperature, and pressure _. increase decrease remain the same Use the drop down word bank to complete the passage. The lithosphere is made up of the crust and upper mantle. It is rigid and broken into several plates. The asthensophere is a layer of hot softened rock in the upper mantle under the lithosphere. Over millions of years the great heat and pressure in the mantle and core have caused solid mantle rock to warm and flow very slowly in a cycle of rising and sinking called convection currents. In which layer of the Earth do convection currents occur? crust inner core mantle What causes the crustal plates to move? Earthquakes Volcanoes convection currents
