How does intrusion X compare to the ages of the other rock layers and fossils in this geologic column?

• Intrusion X is older than layer Y and Z.

• Intrusion X is younger than all the layers.

• Intrusion X is older than the clam and broadleaf.

• Intrusion X is younger than the broadleaf and fern fossils.

A small city gets its drinking water from the river running through its center. This river is fed by rivers that flow down the mountains nearby. How would excessive rainfall in the mountains most likely affect the turbidity of this local water source?

• Heavy rainfall would decrease the turbidity of the river downstream.

• Heavy rainfall would increase the turbidity of the river downstream.

• Heavy rainfall would increase the turbidity only in rivers upstream.

• Heavy rainfall would decrease the turbidity of only rivers upstream.
