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.

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.
Science
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.
Science
Why is the sky blue instead of another color?
Air molecules scatter shorter wavelengths of sunlight more strongly. What reaches your eyes is light redirected by the atmosphere, not a blue surface overhead.
Science
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.
Science
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.”
Science
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.
Science
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.
Science
The world still knows how to put on a show.
Auroras turn an encounter between energetic particles and our atmosphere into light. The show is real; predicting your view is harder.
