Phases of the Moon
Third Quarter,
New Moon,
First Quarter,
Full Moon
When the Sun and the Moon are on same side of Earth, the Sun illuminates the surface of the
Moon not visible to us. On such nights we do not see the Moon. This is the ________________
phase.
Seven days after a New Moon, the Moon enters the __________________________ phase.
During this phase, half of the lit surface of the Moon is visible from Earth.
When the Sun and the Moon are on opposite sides of the Earth, the lit surface of the Moon is
completely visible from Earth. The Moon appears full on such nights. This is known as the
__________________.
Seven days after a Full Moon, the Moon enters the __________________________ phase.
During this phase, only half of the lit surface of the Moon is visible from Earth.

Tides refer to the rise and fall of the ______ level within a ______.
This change in sea level is caused by the __________________________ pull of the Moon and
the Sun on the ____________ of Earth.
During one complete ________________, every point on Earth experiences a ________ tide
when it faces the Moon, a ______ tide when it is at a right angle to the Moon, another high tide
when it faces away from the ________, and a final low tide when it is again at a __________
angle to the Moon.
When the Sun, the Moon, and Earth are aligned on the same axis, the combined gravitation
force of the Sun and the Moon on Earth’s waters lead to ____________ high tides and
__________ low tides. These are called ____________ tides.
During the First Quarter and Third Quarter phases, the Sun, the Moon, and Earth are
__________________________ to each other. This __________________ the gravitational
force between them, which causes the ____________ high tides and the ______________ low
