Question 1

The tides on Earth are caused by the moon and ____.&#10;A) Mars&#10;B) Jupiter&#10;C) Sun&#10;D) Venus

Accepted Answer

The tides on Earth are primarily caused by the gravitational pull of the moon and the sun. The moon's gravitational force has the most significant effect on Earth's tides, but the sun also plays a crucial role, especially in the variation between spring and neap tides.

Question 2

Neap tides occur at ___________ phase of the moon.&#10;A) full&#10;B) new&#10;C) quarter&#10;D) crescent

Accepted Answer

Neap tides occur during the quarter phases of the moon, when the gravitational forces of the moon and the sun are perpendicular to each other, resulting in the least difference between high and low tides.

Question 3

Another term for differential gravitational force is ____.&#10;A) spring tides&#10;B) tidal force&#10;C) neap tides&#10;D) tidal bulge

Accepted Answer

Tidal force is the correct term for differential gravitational force, which refers to the difference in gravitational pull on different parts of an object caused by another object, such as the Moon's effect on Earth's oceans.

Question 4

Tidal forces are slowing the rotation rate of the Earth. This is called&#10;A) spring tide.&#10;B) tidal braking.&#10;C) neap tide.&#10;D) differential force.

Accepted Answer

Tidal braking is the process by which the Earth's rotation is gradually slowed down due to the gravitational interaction between the Earth and the Moon. This interaction causes tidal bulges on Earth, which the Moon's gravity pulls on, creating a torque that slows Earth's rotation.

Question 5

The tides which are above normal are called _____ tides.

Accepted Answer

The answer of The tides which are above normal are...

Question 6

The spring tides occur at new and ______ moon.

Accepted Answer

The answer of The spring tides occur at new and...

Question 7

Tidal braking from the moon speeds up the Earth's rotation.

Accepted Answer

Tidal braking actually slows down the Earth's rotation over time due to the gravitational interaction between the Earth and the Moon.

Question 8

The sun pulls on the Earth with &#188; the tidal pull of the moon.

Accepted Answer

The sun's tidal force on the Earth is less than that of the moon, but it is not as low as ¼. The moon's gravitational pull is stronger in creating tides due to its closer proximity to Earth, despite the sun having a much larger gravitational pull overall.
