Phenomenal Earth

The different phases of the moon are caused by the relative positions of the Earth, moon, and sun. As the moon orbits around the Earth, the amount of sunlight that reflects off its surface changes, resulting in different phases. The changing phases occur because the moon's position relative to the Earth and sun is constantly changing.

Daylight hours vary throughout the year due to the tilt of the Earth's axis and its elliptical orbit around the sun. During summer, the hemisphere tilted towards the sun experiences longer daylight hours, while the hemisphere tilted away from the sun experiences shorter daylight hours. The opposite occurs during winter. The latitude also plays a role, with regions closer to the poles experiencing more extreme variations in daylight hours.

The seasons are caused by the tilt of the Earth's axis. When a hemisphere is tilted towards the sun, it receives more direct sunlight and experiences summer. When a hemisphere is tilted away from the sun, it receives less direct sunlight and experiences winter. The equinoxes occur when the Earth's axis is not tilted towards or away from the sun, resulting in equal day and night lengths, marking the transition between seasons.
