Heat Transfer through Earth's Geosphere / Evolution of Earth

The diagram shows the layers of Earth, not drawn to scale. Which correctly identifies the layers?

• A-mantle, B-inner core, C-outer core, D-crust

• A-crust, B-mantle, C-outer core, D-inner core

• A-inner core, B-outer core, C-mantle, D-crust

• A-outer core, B-inner core, C-crust, D-mantle

Which of the following is the least dense of Earth's layers?

• Crust

• Inner Core

• Outer Core

• Mantle

What characteristic of the outer core makes it unique among the layers of Earth?

• The outer core is the coolest layer of Earth.

• The outer core is liquid due to intense heat.

• The outer core is made of solid iron, giving it a lot of rigidity.

• The outer core is able to flow, even though it is made of solid rock.

Temperature and pressure vary in Earth's layers. In which of the following layers of Earth are temperature and pressure the greatest?

• Crust

• Mantle

• Outer Core

• Inner Core

Earth is made of four layers, each with a different composition. Which of the following is true about one of the layers of the Earth?

• Convection in the mantle results in movement of tectonic plates.

• Intense pressure from the layers above results in solid outer core.

• Movement of liquid metal in the inner core creates Earth's magnetic field.

• Density of the crust is greater than the density of the mantle.

The table lists four objects, each at a different temperature.

If two of these objects are placed together in a container, so the objects are touching, which of the following scenarios correctly describes how heat could flow between the objects?

• Heat will flow from Object 1 to Object 3.

• Heat will flow from Object 1 to Object 4.

• Heat will flow from Object 2 to Object 3.

• Heat will flow from Object 2 to Object 4.

When a liquid substance such as water gains heat energy, which of the following can happen?

• The liquid may become a solid.

• The liquid will always change state and become a gas.

• The liquid may change states, depending on the amount of heat gained.

• The liquid will remain in liquid state, regardless of the amount of heat gained.

The rock cycle is the process by which rocks of one kind change into rocks of other kinds. What must happen for a metamorphic rock to be transformed into an igneous rock?

• It must be weathered into sand grains and compressed into multiple layers.

• It must be soaked in water until it dissolves and reforms in a different shape.

• It must be compressed by high temperatures and pressure within Earth's crust.

• It must be pulled under Earth's crust, melted, and forced out above the crust to cool.
