Landforms on Earth are formed by many processes – both slow and fast. Which of the following correctly describes a landform’s formation?

• As a river flows through an area, it slowly weathers the sides around it.

• Glaciers creep across the land, forming tall mountains.

• A river meets a larger body of water and speeds up, depositing the sediment it was carrying farther into the ocean.

• Sand dunes are formed as waves deposit sand onto a beach.

The layers of Earth are the crust, mantle, and core, with the core being divided into the inner and outer layers. Which of the following does not correctly describe the layers of Earth?

• The crust is extremely thin when compared to the core or mantle.

• The mantle is composed of rocks known as silicates.

• The core is made up of dense elements, such as iron and nickel.

• The core makes up the majority of Earth’s volume.

Rachel is researching the different states that exist in each layer of Earth. While most of the layers are in a single state of either solid or liquid, Rachel finds one layer that contains two different states.

• The inner core is mostly solid nickel with a small amount of liquid iron in the center.

• The outer core contains liquid iron with a few chunks of solid nickel floating in the liquid.

• The upper mantle is part of the solid lithosphere, and the remaining mantle is molten magma.

• The crust has solid continental plates and liquid oceanic plates.

Based on the diagram below, which letter represents a metamorphic rock?

• A. A

• B. B

• C. C

• D. D

The oldest rock formation identified on Earth is found on the shoreline of Hudson Bay in Canada. This rock formed 4.28 billion years ago. Which information does a scientist need to most accurately determine the age of a rock?

• the percentage of each mineral that makes up the rock

• the thickness of younger rock layers that cover the rock

• the amount of each radioactive element present in the rock

• the amount of weathering present on the surface of the rock
