200 points: The moon’s path around the Earth, lasting about 28 days.
200 points: The region of space where life can exist due to conditions like temperature and distance from a star.
Answer: What is the habitable zone?
200 points: This is the opposite of high tide, where water levels are at their lowest.
Answer: What is low tide?
200 points: A yearly cycle where the Earth’s axis causes seasonal changes in weather and daylight hours.
Answer: What are seasons?
200 points: These are the best conditions required for a species to survive and reproduce.
Answer: What are optimal conditions?
300 points: The process in which the Earth spins on its axis, taking 24 hours.
300 points: A large, spherical object that orbits a star, has gravity that keeps it round, and does not have any other large objects in its orbit.
Answer: What is a planet?
300 points: This describes the shape of the Earth’s orbit around the Sun.
Answer: What is an elliptical orbit?
300 points: The path that a planet or object takes around another body, like the Earth around the Sun.

Answer: What is a tidal bulge?
500 points: The pull between two objects that causes one to move toward the other.
Answer: What is gravitational force?
500 points: A small, bright piece of rock or metal that enters the Earth’s atmosphere and burns up, creating a streak of light.
