Causes of Seasons

• Seasons are caused by the Earth's 23.5-degree tilt and its revolution around the Sun.

• When a hemisphere is tilted towards the Sun, it experiences summer; when tilted away, it experiences winter.

Moon's Effect on Tides

• Tides result from the gravitational attraction between the Earth, Moon, and Sun.

• Stronger tides occur when the Sun and Moon's gravity align during full and new moons.

• Weaker tides happen when the Moon is at its first and last quarter phases, as the Sun's gravitational pull partially counteracts the Moon's.

Lunar vs. Solar Eclipse

• Lunar Eclipse: The Earth passes between the Sun and Moon, casting a shadow on the Moon.

• Solar Eclipse: The Moon passes between the Earth and Sun, casting a shadow on the Earth.
