d. ceres
7. why can’t the jovian planets support life, but it is possible their moons can?
a. they are gas giants made of gas, and the moons are made of cheese
b. they are gas giants and have no solid surface, but their moons may have oceans
c. they are gas giants and are too big to support life, but the moons are small enough
d. they are gas giants and do not have enough gravity to support life

Question

Accepted Answer

### Question 6
# Brief Explanations:
Mars is the most explored planet besides Earth due to numerous missions (orbital, rover, etc.) studying its geology, atmosphere, and potential for past/present life. Venus has a harsh environment, Jupiter is a gas giant, and Ceres is a dwarf planet (asteroid belt), so they are less explored than Mars.
# Answer:
b. Mars

### Question 7
# Brief Explanations:
Jovian planets (gas giants like Jupiter, Saturn) are made mostly of gas with no solid surface, making life as we know it impossible. Their moons, however, may have solid surfaces and even subsurface oceans (e.g., Europa), which could potentially support life. Option a is incorrect (moons aren’t made of cheese), c is wrong (size isn’t the main reason), d is wrong (gravity isn’t the limiting factor for life here).
# Answer:
b. they are gas giants and have no solid surface, but their moons may have oceans

### Question 8
# Brief Explanations:
Terrestrial planets (Mercury, Venus, Earth, Mars) are smaller and closer to the Sun. Jovian planets are larger, farther out, and have stronger gravitational fields to capture more moons. Temperature (a), atmosphere (b), or “attractiveness” (c) aren’t the primary reasons for moon count differences.
# Answer:
d. the Terrestrial planets are smaller and closer to the Sun

### Question 9
# Brief Explanations:
The four Galilean moons of Jupiter are Callisto, Io, Ganymede, and Europa. Option a has a made - up moon (Wilymede), b lists non - moon celestial bodies/regions, d has made - up moons.
# Answer:
c. Callisto, Io, Ganymede, Europa

### Question 10
# Brief Explanations:
Dwarf planets in our solar system include Eris, Ceres, Pluto. Gaia is not a dwarf planet (Gaia is a space observatory, and there’s no dwarf planet named Gaia in the solar system).
# Answer:
b. Gaia

### Question 11
# Brief Explanations:
Astronomy is humanity’s first science. Ancient civilizations studied the stars for timekeeping, navigation, and cultural/religious purposes, making it one of the earliest scientific pursuits.
# Answer:
True

### Question 12
# Brief Explanations:
Astronomy is not a newer science. It has been studied for thousands of years by ancient cultures (e.g., Babylonians, Egyptians, Greeks) for various purposes. So the statement is false.
# Answer:
False

### Question 13
# Brief Explanations:
Astrology claims to link celestial positions to human affairs, but it lacks scientific evidence and doesn’t follow the scientific method. Science requires testable hypotheses, evidence, and reproducibility, which astrology doesn’t provide. So the statement is false.
# Answer:
False

### Question 14
# Brief Explanations:
Cultures worldwide have different views on astronomy. For example, the Mayans had complex astronomical calendars, Polynesians used stars for navigation, and different religions have celestial - based myths. They also used astronomy for agriculture, timekeeping, etc. So the statement is true.
# Answer:
True

### Question 15
# Brief Explanations:
Astronomy has practical uses: navigation (e.g., maritime, space), timekeeping, understanding climate (via solar cycles), satellite communication, and inspiring technological advancements (e.g., telescope - related tech). So the statement is true.
# Answer:
True
