1.
Tides are________________________________________________.
Correct Answer
B. The daily rise and fall of the Earth’s water along the shore.
Explanation
Tides are the regular and predictable movements of water caused primarily by the gravitational pull of the moon and the sun acting upon the oceans of the Earth. This phenomenon is characterized by the daily rise and fall of sea levels along the shores. Tides involve the vertical movement of water, influencing coastal environments and marine activities. This definition captures the essence of tidal processes more accurately than the other options provided.
2.
Tides are mostly caused by______________________________.
Correct Answer
C. The Moon’s pull of gravity on the Earth.
Explanation
The moon's gravitational force creates tidal bulges in Earth's oceans. As the moon orbits, it pulls water towards it, causing a high tide directly beneath. Simultaneously, on the opposite side, another high tide occurs due to the Earth being pulled away. This gravitational interaction results in the rhythmic rise and fall of tides.
3.
The farthest point the tide rises up a shoreline is called the
Correct Answer
B. High Tide.
Explanation
High tide is the point when the water level reaches its highest point along the shoreline due to the gravitational pull of the moon and sun. Low tide is the opposite, when the water level recedes to its lowest point. Maximum tide and minimum tide are not standard terms used to describe tidal movements.
4.
The point on the shoreline that the tide decreases the most is called the
Correct Answer
A. Low Tide.
Explanation
The lowest point of the tide during the day is Low Tide.
5.
Which points in the diagram of the earth would have High Tides?
Correct Answer
B. A and C
Explanation
The side of the Earth facing the Moon and the opposite side of the Earth facing away from the moon will have High Tide.
6.
Which points in the diagram of the earth would have Low Tides?
Correct Answer
D. B and D
Explanation
In the diagram, the Earth and the Moon are shown, and the question is asking about the points on Earth that would experience low tides.
Tides are caused primarily by the gravitational pull of the Moon. The areas on Earth directly facing the Moon (point C) and the area directly opposite (point A) experience high tides due to the Moon’s gravitational pull and the centrifugal force from the Earth-Moon system.
The points at right angles to these (points B and D) would experience low tides, as the water is being pulled away from these areas.
Thus, points B and D would have low tides.
The correct answer is: B and D.
7.
A single beach on the Earth would have _______ each day.
Correct Answer
B. 2 High Tides and 2 Low Tides
Explanation
The Earth rotates through each point where there could be a tide each day.
8.
If the Sun, Earth, and Moon are lined up as follows, the Earth would have__________.
Correct Answer
A. Spring Tides, which is when there are very high tides and very low tides.
Explanation
When the Sun, Earth, and Moon line up, the Sun and Moon's gravity combines to make very high tides and very low tides.
9.
If the Sun, Earth, and Moon are lined up as follows, the Earth would have__________.
Correct Answer
D. Neap Tides, which is when there are almost no tides.
Explanation
When the Sun and Moon form a right angle to the Earth, each pulls on the Earth's water in different directions trying to make High Tides all around the Earth. That makes the tides about the same all around the Earth.
10.
Spring Tides happen during ______ and _______ moons and Neap Tides happen during ________ moons.
Correct Answer
C. Full, New, Quarter
Explanation
Spring Tides happen when the Sun, Moon, Earth are in a line and that is during Full and New Moons. Neap Tides happen when the Sun and Moon are not in a line and that happens during Quarter Moons.
