There is less variation in temperature at the
equator during the year than the
temperatures at the poles.
Each Earth day is 24 hours long, the reason
for this is because it takes Earth 24 hours to
rotate once on its axis.
The Northern Hemisphere receives more
solar energy during one half the year than it
does during the other half of the year
because the angle at which sunlight reaches
the Northern Hemisphere changes.

A year on Mars is equal to 687 Earth days
because it takes Mars almost twice as much
time as Earth to orbit the sun once.
When it is winter in the Northern
Hemisphere, it is summer in the Southern
Hemisphere. The reason for this is because
the Northern Hemisphere is tilted away from
the sun and the Southern Hemisphere is
tilted toward the sun.

In January, it is winter in the Northern
Hemisphere. In the Southern Hemisphere it
would be Summer.
During Earth’s rotation, Earth spins on its
axis, causing day and night.

It takes about one month to cycle from one
new moon to the next new moon
When Earth moves into the moon’s shadow,
a solar eclipse takes place. The new moon
phase represents the appearance of the
moon during a solar eclipse.
A satellite is an object that revolves around a
larger object. Many satellites are orbiting
Earth. Gravity is an important factor in
keeping a communications satellite in orbit
around Earth.

The phases of the moon are the changing
appearances of the moon, as seen from
Earth. The waning crescent phase happens
immediately after a third quarter moon.
The phases of the moon are the regular
changes in how the moon looks from Earth.
During the new moon phase the moon not
visible from Earth.
UNIT 4 TEST REVIEW

Sometimes the moon looks like a crescent.
At other times, the moon looks like a half
circle. The Light from the sun is reflected by
the moon’s surface this is what makes it
possible for you to see the surface of the
moon from Earth.

The moons gravitational pull on the Earth
has the greatest effect on tides.
Neap tides take place during the first quarter
and third quarter moon phases.
During the new moon and full moon phases
spring tides take place.

The moon passes over a particular spot on
Earth’s surface, causing tides as a result of
its gravitational pull, once every 24 hours
and 50 minutes.
A tidal range is the difference between the
levels of ocean water at high tide and low
tide.
A tide of maximum range that takes place
two times a month best describes a spring
tide.

The length of a year is different for each
planet in the solar system. An Earth year has
about 365 days in a year.
