5. The tendency of an object to resist a change in its motion.
8. hazards A natural event (like a volcano or wildfire) that can cause harm to humans and the environment.
9. A push or a pull exerted on an object.
12. A non-living part of an ecosystem (e.g., water, rocks, sunlight).
14. The movement of one object around another object (like Earth going around the Sun).
17. A community of living organisms interacting with their non-living environment.
18. A form of energy resulting from the flow of charged particles (electrons).
20. The force that opposes motion between two surfaces that are touching.
21. The process by which plants use sunlight, water, and carbon dioxide to create food.
22. A powerful, swirling tropical storm with high winds and heavy rain that forms over warm ocean waters.

1. The spinning of an object on its axis (causes day and night).
2. A linear sequence that shows how energy is passed from one organism to the next.
3. A non-contact force that attracts or repels certain metals (like iron).
4. A living or once-living part of an ecosystem (e.g., plants, animals, bacteria).
6. A sudden, violent shaking of the ground caused by movements within the Earth's crust.
7. An event where one celestial body moves into the shadow of another.
10. Short-term periods of climate change caused by Earth's tilt and revolution.
11. The study of how living things interact with each other and their environment.
13. The force of attraction that pulls objects toward each other; depends on mass and distance.
15. A giant wave usually caused by an undersea earthquake or volcanic eruption.
16. An organism that makes its own food using energy from the Sun.
19. An organism that gets its energy by eating other organisms.
