How can recycling can help protect Earth’s natural resources?
Recycling helps protect Earth’s natural resources by reducing the need to extract and process new raw materials. When we recycle items like paper, plastic, and metal, we reuse materials instead of throwing them away. This conserves resources like trees, oil, and minerals, and reduces pollution from manufacturing processes. Recycling also helps decrease the amount of waste sent to landfills, which can harm the environment. By recycling, we help preserve natural resources and create a cleaner, healthier planet.

How can shadows help scientists understand the sun's position?
Answer: They can indicate the time of day and direction of light.
Why do the stars change with the seasons?
