Earth's orbit around the Sun and the tilt of its axis result in periodic climate changes known as seasons. Different locations on Earth experience different types of climate changes: Some places have extreme seasonal changes in temperature, while others have little temperature change but have rainy and dry seasons. This interactive activity from the Adler Planetarium explains why Earth experiences seasons, as users place Earth in orbit for particular seasons.
Note: The greatest number of hours of daylight occurs on the summer solstice. During summer, daylight hours begin to shorten, and the number of hours of daylight on a given number of days after the solstice is the same as on that number of days prior to the solstice, in the spring. Also, although Activity 2 presents winter as Queensland's wet season, it is actually wetter there when it is summer in the southern hemisphere.
