Both Ocala, Florida, and Lexington, Kentucky, are good places to raise racehorses, in part because of the limestone near the surface in both places. Calcium from the limestone helps make a horse's leg bones stronger and better able to withstand the pounding stress of running.

Knowing that the Bluegrass Region around Lexington also sits on top of limestone, what other land features are also likely to be found there?

• Sand dunes, lakes, and springs

• Prairies, swamps, and marshes

• Sinkholes, caves, and aquifers

• Shallow rivers, flat land, and quartz sand

What must happen in order for a metamorphic rock to be transformed into an igneous rock?

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

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

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

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

Granite forms when liquid magma slowly cools within Earth’s crust. If the granite is exposed to intense heat and pressure, it can change to gneiss.

Which type of change takes place when granite turns into gneiss?

• Sedimentary rock changes to igneous rock.

• Igneous rock changes to metamorphic rock.

• Metamorphic rock changes to igneous rock.

• Sedimentary rock changes to metamorphic rock.

Declan observed a rock that he found at the beach. The rock felt hard, it was yellow, and it appeared to be made of layers. Declan concluded that the rock was sedimentary.

Which observation best supports this conclusion?

• The yellow color

• The layers within the rock

• The hardness of the rock

• The location where the rock was found

Over time, repeated cycles of heating and cooling can cause a rock to crack. The rock may then break into smaller pieces.

What is this process called?

• Deposition

• Erosion

• Subsidence

• Weathering

As a glacier moves along the ground, it transports rocks. These rocks pass over the ground and create scratches in the bedrock.

Which statement correctly describes these processes?

• The transport of rocks and scratching of the bedrock are both examples of erosion.

• The transport of rocks and scratching of the bedrock are both examples of weathering

• The transport of rocks is an example of erosion, and the scratching of the bedrock is an example of weathering.

• The transport of rocks is an example of weathering, and the scratching of the bedrock is an example of erosion.

Emily used a tray filled with dirt as a model of a stream. Emily poured water into the top of the tray and observed how much erosion happened. Emily then increased the slope of the tray and repeated the experiment.

What would happen when the slope of the tray increased?

• The speed of the water and the amount of erosion would increase.

• The speed of the water and the amount of erosion would decrease

• The speed of the water would increase, while the amount of erosion would decrease

• The speed of the water would decrease, while the amount of erosion would increase.

The table below gives some information about four Florida lakes. Based on the information given, which lake is most likely to be a sinkhole lake?

• Lake Annie

• Lake George

• Lake Okeechobee

• Lake Washington
