The gravitational pull of which of the following is MOST responsible for tides on Earth?
Correct Answer
A. Moon
Explanation
The moon's gravity is primarily responsible for tides on Earth. When the Earth/Moon/Sun are directly lined up, the Sun's gravitational force can add to the moon's gravity to create higher tides called "flood' tides.
28.
This is the Bay of Fundy in eastern Canada. The moon's gravity pulls on Earth's oceans and literally pulls the water toward the moon (a little bit). Generally, most shorelines experience 2 high tides and 2 low tides every day.

This model shows the Earth/Moon/Sun as seen from space. Seen from space looking "down" on the Earth and moon, HALF of the Earth and HALF of the moon are always illuminated. On Earth, however, we can't always see the whole illuminated side of the moon. Depending on the angle of the Earth and moon, we see "phases" of the moon. Which of the following shows the new moon phase?
Correct Answer
A. 1
Explanation
The new moon occurs when the moon is between the Earth and Sun. We can NOT see the illuminated half of the moon. This is called the new moon.
