Lesson 6.1 – Earth’s Layers Earth and Space Lesson 6.1 – Earth’s Layers

I can list the layers of the Earth and explain which layers are in the lithosphere and which are in the asthenosphere. (3f) 1. The Earth has four main layers: the inner core, the outer core, the mantle, and the crust.

2. The crust of the Earth is also referred to as the lithosphere. I can list the layers of the Earth and explain which layers are in the lithosphere and which are in the asthenosphere. (3f) 2. The crust of the Earth is also referred to as the lithosphere. The crust is made up of rock. The Earth’s crust underneath the oceans in about three times thinner than the crust that makes up the continents.

I can list the layers of the Earth and explain which layers are in the lithosphere and which are in the asthenosphere. (3f) 3. The top portion of the mantle is also referred to as the asthenosphere. The entire mantle, including the asthenosphere, is made of molten (melted) rock.

4. The inner and outer core is made up of iron, a type of metal. I can list the layers of the Earth and explain which layers are in the lithosphere and which are in the asthenosphere. (3f) 4. The inner and outer core is made up of iron, a type of metal. The outer core is liquid iron and the inner core is solid iron. 5. As we move toward the Earth’s core, the temperature increases.

I can list the layers of the Earth and explain which layers are in the lithosphere and which are in the asthenosphere. (3f) 1. Label the five layers of the Earth on the diagram at the right. 2. For each layer, put an L for liquid and an S for solid. 3. Put a star next to the layer that is the lithosphere and an x next to the layer that is the asthenosphere.

Both are hot, liquid inner layers of earth. 5. Which of the following correctly compares the lithosphere and the asthenosphere? The lithosphere is solid and cool, and the asthenosphere is hot and liquid. The asthenosphere is solid and cool, and the lithosphere is hot and liquid. Both are hot, liquid inner layers of earth. Both are solid, cool layers of earth close to the surface. A
