Kevin travels to Australia for the winter, but it is more like summer. Why is this
The Southern Hemisphere is tilted towards the sun, so it is summer in Australia.

From west to east
What defines season
A specific time of the year that is characterized by reoccurring weather conditions.
Once a month, Earth passes between the moon and sun. Is a solar eclipse possible during this time
No, because full moons happen when earth is between the moon and sun, and solar eclipses only happen during new moons
