The Limits of Natural Selection AMPLIFY

What is natural selection?

• A process where organisms with favorable traits survive and reproduce
• A process where organisms choose their mates based on physical appearance
• A process where organisms change their traits to adapt to their environment
• A process where all organisms have equal chances of survival

What can happen when the environment changes too quickly for populations to adapt?

• The populations evolve faster
• The populations die out
• The populations remain unchanged
• The populations migrate to a different environment

What is a mass extinction?

• An event where all species on Earth go extinct
• An event where a large number of species go extinct in a short period of time
• An event where a large number of species evolve rapidly
• An event where a single species goes extinct

What factors contributed to the extinction of dinosaurs?

• A sudden decrease in Earth's temperature
• Overhunting by other species
• A huge asteroid impact and massive volcanic eruptions
• A global pandemic

How do rock layers provide evidence of mass extinctions?

• By showing a sudden disappearance of species' fossils in later rock layers
• By showing a sudden increase in the number of species in later rock layers
• By showing the exact cause of the mass extinction
• By showing a gradual decrease in the number of species over time

What human activities are contributing to the potential mass extinction of current species?

• Deforestation, overfishing, pollution, and climate change
• Recycling, conservation efforts, and renewable energy
• Decreasing the use of fossil fuels and promoting sustainable agriculture
• Planting trees and protecting endangered species
