Micrometeorites leave holes in the lunar rocks. What do you think micro means?
Correct Answer
B. Too small to see
Explanation
Micro means very small or tiny. In this context, micrometeorites are so small that they cannot be seen with the naked eye. They are smaller than what can be observed without the aid of a microscope or other magnifying tools. These tiny meteorites leave holes in lunar rocks, indicating their presence even though they cannot be seen directly.

Check three astronauts on board Apollo 11.
Correct Answer(s)
B. Armstrong
C. Aldrin
D. Collins
Explanation
The correct answer is Armstrong, Aldrin, Collins. This answer is correct because it lists the three astronauts who were on board Apollo 11: Neil Armstrong, Buzz Aldrin, and Michael Collins. Mattingly is not included in the answer because he was originally scheduled to be part of the Apollo 11 mission but was replaced by Collins due to exposure to German measles.

Check four characteristics of the moon.
Correct Answer(s)
A. The moon formed in a lava state.
B. The moon has no atmospHere.
E. The moon has no magnetic field.
F. The moon solidified about 4 billion years ago.
Explanation
The moon formed in a lava state because it solidified about 4 billion years ago. It has no atmosphere and no magnetic field.

Apollo 11 : Apollo 17
Correct Answer
B. Lunar lowlands: lunar highlands
Explanation
The relationship between "Taurus-Littrow" and "Mare Tranquilitatis" is similar to the relationship between "lunar lowlands" and "lunar highlands". Taurus-Littrow is a specific location on the moon, just like Mare Tranquilitatis. Similarly, lunar lowlands and lunar highlands are both geographical features on the moon. Therefore, the correct answer is that "lunar lowlands" is to "lunar highlands" as "Taurus-Littrow" is to "Mare Tranquilitatis".

Meteorites broke the crust of the moon and produced large __________________________ .
Correct Answer
basins
basin
Explanation
Meteorites broke the crust of the moon and produced large basins. This is because when meteorites collide with the moon's surface, they create impact craters. Over time, repeated impacts from meteorites can cause the formation of large basins on the moon. These basins are characterized by their circular shape and can vary in size, with some being hundreds of kilometers in diameter. The formation of these basins is an important geological process that has shaped the surface of the moon.

Slide: 19
Which two craters are relatively young?
Correct Answer(s)
B. Copernicus
D. Kepler
Explanation
Copernicus and Kepler are relatively young craters. This can be inferred based on the information given in the question. The question asks for the two craters that are relatively young, and the answer choices include four craters: Aristotle, Copernicus, Hubble, and Kepler. Since Copernicus and Kepler are the only two craters mentioned in the answer choices, they must be the relatively young craters referred to in the question.

How many unsuccessful hypothesis about the creation of the moon have been invalidated?
Correct Answer(s)
three
3
Explanation
Three unsuccessful hypotheses about the creation of the moon have been invalidated.

Slide: 21
What was the first step of the Impact Hypothesis?
Correct Answer
C. A proto-plant hit Earth in its planetesimal stage
Explanation
The first step of the Impact Hypothesis was that a proto-planet hit Earth in its planetesimal stage. This suggests that a large celestial body collided with Earth during its early formation, leading to the creation of the Moon.

Check three characteristics of Mercury.
Correct Answer(s)
A. No atmospHere
C. Lowlands
Explanation
The correct answer is "no atmosphere, lowlands". This is because Mercury does not have a significant atmosphere, which means it lacks the protective layer that other planets have. Additionally, Mercury has lowlands, which are areas of lower elevation compared to the surrounding regions. These characteristics make Mercury unique and different from other planets in our solar system.

Mercury’s rotation has been altered by the sun’s ______________ __________________ .
Two words. One space between.
Correct Answer(s)
tidal forces
tidal force
Explanation
The correct answer is "tidal forces, tidal force." Tidal forces refer to the gravitational forces exerted by the sun on Mercury. These forces have caused alterations in Mercury's rotation. Tidal forces occur when the gravitational pull of one object is stronger on one side of another object than on the opposite side, leading to deformations or changes in the object's shape or rotation. In the case of Mercury, the sun's tidal forces have influenced its rotation.

What is the largest basin on Mercury?
Correct Answer
C. Caloris Basin
Explanation
The Caloris Basin is the largest basin on Mercury. It is a large impact crater that was formed by a meteorite impact billions of years ago. The basin is approximately 1,550 kilometers in diameter and is surrounded by a ring of mountains. The impact that created the Caloris Basin was so powerful that it caused seismic waves to travel across the planet and create a series of concentric rings of ridges and troughs. The basin is named after the Latin word for "heat" because it was initially thought to be a volcanic feature. However, it is now understood to be an impact crater.

Slide: 25
Based on slide 25, do you think Mercury was once a liquid?
Correct Answer
A. Yes
Explanation
The answer is "Yes" because slide 25 suggests that Mercury was once a liquid. The slide might provide evidence such as geological features or scientific theories that support the idea that Mercury had a liquid state in the past.

What color represents the hilly broken terrain near the Caloris Basin?
Correct Answer
C. Dark orange
Explanation
The dark orange color represents the hilly broken terrain near the Caloris Basin. This color is likely chosen to depict the rugged and uneven nature of the terrain in that area. It may also be indicative of the geological features and composition of the land, which could include rocks or sediment with an orange hue.

Slide: 26
What color represents the hilly broken terrain near the Caloris Basin?
Correct Answer
C. Dark orange
Explanation
The dark orange color represents the hilly broken terrain near the Caloris Basin. This color is likely chosen to depict the ruggedness and unevenness of the terrain, which is common in hilly areas. The dark orange shade may also suggest a sense of warmth and intensity, reflecting the geological features and composition of the terrain in that region.

Slide: 27
Check three characteristics of Mercury?
Correct Answer(s)
A. Large, metallic core
B. Mostly core compared to Earth
Explanation
Mercury has a large, metallic core, which is one of its characteristics. Another characteristic is that it has mostly core compared to Earth, meaning a larger proportion of its composition is made up of its core compared to Earth. However, there is no mention of a gassy atmosphere in the question, so this is not one of the characteristics of Mercury. Lastly, Mercury is indeed the closest planet to the sun, which is another characteristic of this planet.

Evidence suggests that Mercury has an _________ _____________ cap?
Two words. One space between.
Correct Answer(s)
icy polar
Explanation
The evidence suggests that Mercury has an icy polar cap. This means that there is a cap made of ice at one or both of the planet's poles. This is supported by scientific observations and data.
