False. Contour lines indicate different levels of elevation. One line might indicate an elevation of 100 feet, and the line next to it an elevation of 200 feet, and so on. When those lines are close together it means that the elevation is rising very quickly from 100 feet to 200 feet, which means a steeper slope. When those lines are farther apart, it means that there's a lot more space between the 100-foot elevation and the 200-foot elevation, which means a more gentle slope.
Answer:
1. Litosphere: made of large plates that move.
2. Asthenosphere: plastic portion of the upper mantle of the earth.
3. Outer core: very dense liquid of iron and sulfur.
4. Crust: thin, rigid surface of Earth.
5. Inner core: made of solid iron.
6. Upper mantle: layer that includes the asthenosphere.
7. Lower mantle: layer just outside of the outer core.
