gravitational field.
The two factors that affect the force of
gravity between two objects in space are
A teacher draws four diagrams on
the board to explain the effects of
the position of the moon on the
tides. She asks a student to describe
the type of tide that will be formed.
Complete the student’s table using
the descriptions below:
- first quarter moon causing neap
tides
- full moon causing spring tides
- third quarter moon causing neap
tides
- new moon causing spring tides

A ___________ tide would be created
from the positioning of the Sun, moon
and Earth in the above diagram.
Draw two diagrams with the Sun, Moon,
and Earth in the correct positions to
create the highest high tide and the
lowest low tide.
