As the Moon orbits the Earth, consider two situations. In situation A, the Moon is

directly between the Earth and the Sun. In situation B, the Moon is on the other

side of the Earth, so that the Earth is directly between the Moon and the Sun.

Which of the following statements is true regarding the tides on the Earth in these

two situations?

a) In situation B, the difference between the height of the high tide and the height

of the low tide is larger than it is in situation A.

b) In situation B, the difference between the height of the high tide and the height

of the low tide is the same as it is in situation A.

c) In situation B, the difference between the height of the high tide and the height

of the low tide is smaller than it is in situation A, but it is not zero (i.e., there is

still a high tide and a low tide in situation B).

d) In situation B, the difference between the height of the high tide and the height

of the low tide is zero (i.e., there is not a high tide or a low tide in situation B).

Answer #1

Answer-Tides are basically caused by the gravitational force exerted by both the sun and the moon.

High tides occurs when the Earth ,moon and sun align on the same axis, this situation is called the lunar eclipse ,spring tides occur.

In the given question situationA is called the NEW MOON( the Moon is directly between the Earth and the Sun) . And the situationB is called the FULL MOON(the Earth is directly between the Moon and the Sun.).

During New moon high tides occured  and also during new moon day tides are high.

so option ( b) will be right.Tides will be same in both cases.

1. On occasion, the Earth-Moon-Sun system is aligned such that the Earth or Moon casts a shadow partially or directly on the other body. These events are called eclipses. A lunar eclipse happens when the Moon passes through the Earth’s shadow. A solar eclipse occurs when the Moon is in a position where it blocks sunlight from getting to Earth. A. Draw a Sun-Earth-Moon diagram for each kind of eclipse (lunar and solar). Make sure you draw your diagrams large...
