 Earth spins on an imaginary line called its ______Axis _________________.
 Fill in the following chart with the missing information.
Earth’s
Movement
Definition
How Long it
Takes
Earth spins on a
24 hours
tilted imaginary line
called an axis.
Rotation:
365 Days = 1 year
Day and Night
Cycle
The Seasons:
Winter, Spring,
Summer, Fall
This means Earth
moves in a regular
path around the
Sun.
 What TWO things cause Earth to have seasons?

An Example
(Draw)
Earth spinning on
its axis is called
rotation.
Earth orbits, or
revolves around
the sun.
Revolution:
This Causes…
Orbit of Earth
Tilt of Earth
Electrons orbit around
the nucleus of an atom.
 Be able to understand what season is happening in the different hemispheres when Earth is at
different locations around the Sun.
 What would happen to the movement of the planets if all of a sudden, there was no Sun?
The planets would fly out in to space because there is no gravity, or force to hold them in place.
Tides and Moon Phases
 Define tides: The daily rise and fall of Earth’s waters on the shorelines.
 What causes the tides?
Caused by the gravitational pull between the Earth, moon, and Sun.
 Which has a greater affect on the tides, the Sun or the Moon? Why??
The Moon has a greater affect on the tide than the Sun because the Moon is much closer to the Earth
than the Sun.
 What is the difference between a spring tide and a neap tide?
During a neap tide, the sun and the moon are at right angles to each other. During a spring tide, the sun
and the moon are lined up.
 In the spaces below, draw a diagram of a spring tide and a diagram of a neap tide.
Spring Tide
Neap Tide
 Why do we see different phases of the moon?
As the Earth revolves around the Sun, the Moon revolves around the Earth.
The phase of the Moon you see depends on how much of the sunlit side of the moon is facing
Earth.
 Complete the following sentences:
o A solar eclipse happens when…the moon passes between the
Earth and the Sun. The moon is blocking sunlight from reaching the
Earth.
o A lunar eclipse happens when… the Earth passes between the
Moon and the Sun. The Earth is blocking sunlight from reaching the
Moon.
