How do rainbows form—and why are there sometimes two?
Sunlight bends and reflects inside water droplets. A second rainbow takes an extra reflection, reversing the order of its colors.

What causes ocean tides to rise and fall?
The Moon and Sun help drive tides. Spring and neap tides describe changing ranges, not changing seasons.
Why do leaves change color in autumn?
Green chlorophyll fades as the season changes. Other pigments become visible, and some leaves produce the reds that make autumn vivid.
Why do stars twinkle when we look up?
The flicker usually comes from moving air above us. Starlight takes a shifting path through Earth’s atmosphere before reaching your eyes.
Why does the Moon seem to change shape?
The Moon keeps its shape. Our view of its sunlit half changes as it travels around Earth, creating the familiar lunar phases.
What causes the seasons? Earth’s tilt explains the switch
Earth’s tilted axis changes the angle and duration of sunlight through the year. Being closer to the Sun does not explain why the hemispheres have opposite seasons.
What does a 40% chance of rain actually mean?
The percentage describes a chance of measurable rain at a location during a stated period. It does not tell you how much of your day will be wet.
What does the feels-like temperature actually mean?
Feels-like values put conditions such as wind or humidity alongside air temperature. The calculation has assumptions, so it is not a second thermometer reading.
What is the difference between weather and climate?
Weather describes shorter-term atmospheric conditions. Climate describes longer-term patterns—and the reference period matters when someone says a day is “normal.”
Why can you see the Moon during the day?
The Moon reflects sunlight during daytime too. Whether you can spot it depends on its position, phase, your location, and the view of the sky.
Why do sunsets turn red and orange?
Sunlight takes a longer route through the atmosphere when the Sun is low. More short-wavelength light is scattered away, changing the colors that reach us.
Why do weather apps show different forecasts?
Different models, forecast windows, and symbols can turn the same uncertain weather into different-looking answers. Compare the details before declaring one app wrong.
