As altitude increases, the number of air molecules decreases, and the air becomes less dense, leading to a decrease in air pressure.

Clouds reflect sunlight, reducing the amount of heat that reaches the Earth's surface, which makes the temperature feel cooler and more comfortable on cloudy days.

During the day, land heats up faster than water. The warm air over the land rises, and cooler air from the ocean moves in to replace it, creating a sea breeze.

During sunset, the sun’s light passes through a thicker layer of the atmosphere. The shorter wavelengths (blue and green) are scattered, leaving longer wavelengths (red and orange) to reach our eyes.

The ship's large hull displaces a sufficient amount of water to balance the weight of the ship. This is based on Archimedes’ principle, which states that an object will float if it displaces a volume of water whose weight is equal to the object's weight.

Ice is less dense than liquid water because the molecules in ice are arranged in a crystalline structure that takes up more space, making ice buoyant.

Fire emits infrared radiation, which is absorbed by your skin, causing an increase in body temperature when you're close to the fire.

Heat from sunlight causes the air molecules inside the tire to move faster and spread out, increasing the air pressure and making the tire appear inflated.

When the air inside the balloon is heated, it becomes less dense than the cooler air outside, causing the balloon to rise due to buoyancy.

Iron is a magnetic material, meaning it can be magnetized. When placed near a magnet, it is attracted because of the alignment of magnetic domains within the iron.
