Plants are growing on the surface of this pond. How do plants like these form fossil fuels?

• Dead plants sink to the bottom and get buried by sediment for millions of years.

• Dead plants sink to the bottom and get consumed by decomposers.

• Dead plants produce carbon dioxide for the fish, which form fossil fuels.

• Dead plants get buried for millions of years and form fossils that attract carbon.

The model below shows layers of sediment on the floor of an ocean. Which is the best explanation of how these layers can become rock over years?

• Sand in the sediment melts and turns into rock.

• The weight of the water compacts the sediment into rock.

• Changing water temperatures turn sand in the sediment into rock.

• Pollution caused by humans turns the sediment into rock.

The leaves of two types of plants that live in different environments are shown in the pictures. The leaves of both plants have different structures. What differences in the structure of the leaves of these plants likely help them survive in their environments?

• The pan-like shape of the giant water lily leaves helps them catch rainwater. The slim shape of the mesquite leaves helps them avoid sunlight

• The broad shape of the giant water lily leaves helps them stay on the water surface. The slim shape of the mesquite leaves helps them prevent water loss.

• The pan-like shape of the giant water lily leaves helps them attract small fish. The slim shape of the mesquite leaves helps them avoid herbivores

• The broad shape of the giant water lily leaves helps them attract aquatic birds. The slim shape of the mesquite leaves helps them attract pollinators.

A student places 250 g samples of clay, sand, gravel, and silt in separate flower pots. The pots are set on a wire rack, and dishes are placed beneath the pots so that water can drip through holes and collect. The student then pours 100 mL of water over the sample in each pot. The student measures the time it takes for water to begin dripping from the bottom of each pot.What property of soils is the student most likely examining with this procedure?

• The amount of time it takes different soils to dry

• How well different soils retain water

• How much water is needed to dissolve different soils

• The differences in texture between wet and dry soils
