Science 5th

What causes day and night on Earth?

• Movement of the Sun

• Rotation of the Earth on its axis

• Tidal forces

• Revolution of the Moon around Earth

Explain how the rotation of the Earth affects the length of a day.

• The rotation of the Earth causes the length of a day to be 48 hours.

• The rotation of the Earth causes the length of a day to be 365 days.

• The rotation of the Earth causes the length of a day to be 12 hours.

• The rotation of the Earth causes the length of a day to be approximately 24 hours.

How does the rotation of the Earth impact the direction of winds?

• Earthquake impact

• Tornado influence

• Coriolis effect

• Wind effect

Describe the concept of the Coriolis effect in relation to Earth's rotation.

• The Coriolis effect is the apparent deflection of moving objects caused by the rotation of the Earth.

• The Coriolis effect is a result of the Earth's elliptical orbit

• The Coriolis effect only affects objects moving north to south

• The Coriolis effect is caused by the Earth's magnetic field

What is an ecosystem?

• A group of unrelated organisms living together

• A single organism in its environment

• A man-made structure for wildlife preservation

• A community of living organisms in conjunction with the nonliving components of their environment.

Give an example of a predator-prey relationship in an ecosystem.

• Wolves hunting carrots

• Sharks hunting pineapples

• Eagles hunting rocks

• Lions hunting zebras

Explain the role of decomposers in an ecosystem.

• Decomposers break down dead organisms and organic matter, releasing nutrients back into the ecosystem.

• Decomposers reduce the amount of oxygen in the ecosystem.

• Decomposers create new organisms in the ecosystem.

• Decomposers primarily feed on live organisms in the ecosystem.

How do plants and animals depend on each other in an ecosystem?

• Plants and animals depend on each other for oxygen, carbon dioxide, food, shelter, pollination, and seed dispersal.

• Plants and animals depend on each other for transportation

• Plants and animals depend on each other for entertainment purposes

• Plants and animals depend on each other for communication through telepathy

Discuss the importance of biodiversity in maintaining ecosystem balance.

• Biodiversity is important for ecosystem balance as it stabilizes ecosystems, enhances resilience, and promotes nutrient cycling.

• Ecosystems are more stable with less biodiversity

• Nutrient cycling is not affected by biodiversity

• Biodiversity has no impact on ecosystem balance

What are some human activities that can disrupt ecosystem interactions?

• Conservation efforts

• Deforestation, pollution, overfishing, introduction of invasive species, habitat destruction

• Climate change

• Urbanization
