Week 28

What is the primary cause of earthquakes?

• Sudden weather changes

• Movement of tectonic plates

• Lunar cycles

• Volcanic eruptions

Which of the following best describes Darwin's finches?

• A group of finches that all have the same beak shape

• A group of finches that evolved on the Galapagos Islands, showing a variety of beak shapes adapted to different food sources

• A type of finch that Darwin discovered in Australia

• Finches that Darwin genetically modified in his experiments

What is the main effect of volcanic eruptions on the surrounding environment?

• Immediate cooling of the area

• Increase in plant growth due to ash deposition

• Destruction of habitats and release of gases that can alter climate

• Creation of new water sources

Which statement best describes the process of natural selection?

• Animals choosing what traits they want their offspring to have

• The strongest animals surviving and reproducing, passing on their traits

• A random process that changes the traits of animals over time

• Humans breeding animals to produce desired traits

What is a common precursor to an earthquake?

• Heavy rainfall

• A solar eclipse

• Foreshocks

• A sudden drop in temperature

How do volcanic eruptions contribute to the Earth's atmosphere?

• By removing all oxygen

• By adding gases like carbon dioxide and sulfur dioxide

• By cooling the atmosphere immediately

• By producing oxygen

What role do finches' beak sizes and shapes play in their survival on the Galapagos Islands?

• They have no impact on their survival

• They determine the type of music the finches can produce

• They affect the types of food the finches can eat, influencing their survival

• They are purely for attracting mates

Which of the following is a key principle of natural selection?

• All species can adapt to any environment if given enough time

• Only the largest and strongest individuals of a species will survive

• Individuals with traits better suited to their environment are more likely to survive and reproduce

• Species do not change over time

What is one of the main dangers of living near a volcano?

• Constant noise pollution

• Risk of earthquakes

• Risk of pyroclastic flows

• High temperatures preventing plant growth

How does biodiversity contribute to the resilience of an ecosystem?

• By ensuring that all species have the same diet, reducing competition

• By increasing dependency on a single species for survival

• By providing varied sources of food and shelter, enhancing ecosystem stability

• By promoting rapid climate changes that test the ecosystem's strength
