The Winter Solstice, occurring on December 21st. The rotational axis of the Earth is not perpendicular to the Sun, but is slanted. The North Pole is angled more directly toward the Sun on June 21st and more away from the Sun on December 21st. When the North Pole is slanted more away from the Sun, the northern hemisphere is receiving less solar energy than is the southern hemisphere. So, it's colder.
Earth Day in the southern hemisphere is celebrated on the same day as in the northern hemisphere, which is April 22nd. This day is dedicated to raising awareness about environmental issues and promoting sustainable practices to protect the Earth. Activities and events may vary depending on the region and climate of the southern hemisphere.
