Fossils are the preserved remains of organisms that lived long ago. According to the law of superposition, the rock layers that contain fossils should be far below Earth’s surface. Which answer best explains why fossils are sometimes found at or near the surface?

• a. Fossils are less dense than rock, so they rise to the surface.

• b. Fossils are moved to the surface by other organisms.

• c. Sedimentary rock layers are relatively soft, and new fossils sink through upper layers into older, deeper layers.

• d. Some rock layers with fossils have been exposed because of different processes, such as faulting, folding, and weathering.

Which of the following best describe the processes of erosion and weathering?

• The transport of rocks and scratching of the rock below are both examples of weathering.

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

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

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

What is natural selection?

• The process by which individuals that are better suited to their environment survive and reproduce most successfully.

• The ability of an animal to change its color for camouflage.

• The process by which all organisms spontaneously generate from non-living matter.

• A random process that leads to the development of new species without environmental influence.

What is an adaptation?

• A temporary change in behavior in response to an environmental challenge.

• A physical or behavioral trait that improves an organism's ability to survive and reproduce in its environment.

• A conscious decision by an organism to change its appearance.

• A random mutation that has no impact on an organism's fitness.

Lori is learning about two parts of the rock cycle: weathering and erosion. She needs to explain how weathering and erosion are different. Which of the following correctly describes the difference between weathering and erosion?

• Weathering is the movement of rocks by the wind; erosion is the movement of rocks by the water.

• Weathering is the breaking down of rocks; erosion is the movement of weathered materials.

• Weathering is the formation of rocks from lava; erosion is the weathered materials from an area.

• Weathering is when rocks change from one type of rock to another; erosion is when rocks are broken down.
