A tide with the largest difference between water levels at high and low tides is known as a spring tide. Two spring tides occur in each lunar cycle. This is because a spring tide occurs when the Moon

• is closest to Earth.

• and the Sun pull on Earth at a 90° angles.

• and the Sun are aligned and pull on Earth.

• is farthest from Earth.

Which of the following statements best describes how Earth's movement and tilt affects its periods of daylight and seasons?

• Earth's rotation produces unequal periods of daylight and climate patterns called seasons.

• Earth's tilt produces unequal periods of daylight and climate patterns called seasons.

• Earth's rotation and its tilt produce unequal periods of daylight and climate patterns called seasons.

• Earth's revolution and its tilt produce unequal periods of daylight and climate patterns called seasons.

How could this model be altered to correctly illustrate a lunar eclipse?

• The Moon should be moved to the left of the Earth, directly in line with the Sun’s rays.

• The Moon should be moved to the right of the Earth, directly in line with the Sun’s rays.

• The Moon should be left where it is, and the Earth should be moved closer to the Sun.

• The Moon should be moved to the left of the Sun, so the Sun is in between the Moon and the Earth.

A student observes the Moon with a telescope for six months. He concludes that regardless of the time of the observation, the side of the Moon that faces Earth is always the same, as shown in the image. What is the best explanation for this phenomenon?

• The Moon rotates on its axis at a faster rate than it orbits Earth.

• The Moon rotates on its axis at the same rate at which it orbits Earth.

• The Moon does not rotate on its axis due to its comparatively smaller size.

• The Moon does not rotate on its axis due to the strong gravitational pull of Earth.

Describe a solar eclipse and explain the order of the positions of the Sun, Moon, and Earth during a solar eclipse.

• A solar eclipse is when the sun puts it foot out and trips the moon. The moon falls from the sky and hits Earth.

• A solar eclipse produces its own light. There is only one source of light in our solar system, and that is the Sun.

• A solar eclipse occurs when Earth's shadow blocks the sun's light, which otherwise reflects off the moon.

• A solar eclipse occurs when the Moon appears to block the Sun from view on Earth. During a solar eclipse, the Sun, Moon, and Earth are aligned, with the Moon directly between the Sun and Earth.
