1. Scientific Explanation
Rainfall:
Rainfall occurs when water vapor in the atmosphere condenses into liquid droplets. As these droplets become heavier, they fall to the ground as rain. Water vapor originates from bodies of water (oceans, lakes, rivers), plants (evapotranspiration), and the earth's surface. When this vapor rises, it cools and condenses around tiny particles called aerosols, forming clouds. As clouds grow thicker and the droplets become too heavy to stay suspended, they fall as precipitation.
Shooting Stars:
Shooting stars are caused by small debris, such as dust and meteoroids, entering the Earth's atmosphere. When these particles collide with molecules in the air, they create friction, which heats them up and causes them to glow. As the particles burn up, they leave a visible trail of light that appears as a shooting star. Shooting stars are not actual stars but rather the result of tiny pieces of interplanetary material.
