What is the correct order (starting from the surface) of Earth's layers?

• crust, outer core, inner core, mantle

• mantle, outer core, inner core, crust

• crust, mantle, outer core, inner core

• outer core, inner core, crust, mantle

Which of the following processes allow sedimentary rocks to be produced?

• melting

• compaction and cementation

• extreme heat and pressure

• melting so that magma can be produced

Which layer of the Earth is composed mostly of molten rock and is located directly below the crust?

• Lithosphere

• Asthenosphere

• Mantle

• Outer Core

Which statement best describes the Law of Superposition?

• Each sedimentary layer of rock represents 1,000 years of Earth’s age, much like the rings of a tree.

• In undisturbed layers of sedimentary rock, the upper rock layers are older than the lower rock layers.

• In undisturbed layers of sedimentary rock, the lowest layers contain the older rocks.

• Rocks that form near volcanoes are older than surrounding rock.
