Solution
The tidal bulges of the Moon and Sun line up during the New Moon and Full Moon phases.
Here's why:
-
Tidal bulges are caused by the gravitational pull of the Moon and the Sun on the Earth's oceans.
-
During the New Moon phase, the Moon and the Sun are on the same side of the Earth. This means their gravitational forces combine to create larger than usual tides, known as spring tides.
-
During the Full Moon phase, the Moon and the Sun are on opposite sides of the Earth. Despite being on opposite sides, the Sun and Moon's gravitational forces still align, again resulting in spring tides.
-
During the First and Third Quarter phases, the Sun and Moon are at right angles to each other in relation to Earth. This results in their gravitational forces partially cancelling each other out, leading to smaller than usual tides, known as neap tides.
So, the tidal bulges of the Moon and Sun line up during the New Moon and Full Moon phases.
