Bees make honey by collecting nectar from flowers, storing it in their special honey stomach, and then passing it between bees to break down the complex sugars into simpler ones. They finally deposit the processed nectar into honeycomb cells and fan it with their wings until most of the water evaporates, creating honey.

Earth has seasons because its axis is tilted at about 23.5 degrees as it orbits the sun, causing different parts of Earth to receive more or less direct sunlight at different times of year. This tilt, not Earth's distance from the sun, is what creates summer, fall, winter, and spring.

Earthquakes are caused by the sudden release of energy stored in rocks beneath Earth's surface, usually when tectonic plates shift and collide. This movement creates seismic waves that shake the ground.
