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.

Scientists have found traces of organic compounds on some meteorites. This finding would support which of these hypotheses about the origin of macromolecules on Earth?

• Organic molecules arrived on Earth with space debris.

• Organic molecules developed as Earth cooled in space.

• Organic molecules formed in space during the big bang event.

• Organic molecules received energy from ultraviolent radiation from space.

A fossil discovered in Colorado dates from the early Mesozoic era. A year later a similar fossil is found in Wyoming that also dates from the early Mesozoic era. These two organisms most likely lived in...

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.
