Which statement best explains why Venus is hotter than Mercury despite being further from the Sun?, A.Mercury has no moons to reflect heat back to its surface, B.Venus has a thick atmosphere that traps heat through a greenhouse effect., Mercury rotates faster, allowing it to cool down more quickly., The surface gravity of Venus is higher, compressing the air and generating heat., As of early 2026, Saturn is officially recognized as the "Moon King" of the Solar System with a total of 274 confirmed moons., TRUE, FALSE, An astronaut weighs 800 Newtons on Earth. If the surface gravity on Mars is 3.7 m/s² and Earth's is 9.8 m/s², approximately how much would the astronaut weigh on Mars?, 800 N, 302, 2118 N, 130, Earth takes 365.25 days to revolve around the Sun. According to Kepler's Laws and planetary data, how does the orbital period change as a planet's distance from the Sun increases?, The orbital period decreases because the planet moves faster to stay in orbit., The orbital period remains constant for all planets in the same solar system., The orbital period depends only on the planet's mass, not its distance., The orbital period increases as the distance from the Sun increases., Most meteoroids burn up in Earth's atmosphere because of the vacuum of space pulling them in at high speeds., TRUE, FALSE, The atmospheres of Earth and Mars are very different. Earth's atmosphere is roughly 78% Nitrogen and 21% Oxygen, while Mars is about 95% Carbon Dioxide. If Mars has a high percentage of a greenhouse gas (CO2), why is its average temperature still -65°C?, Carbon dioxide only traps heat if oxygen is also present., The Martian atmosphere is too thin to retain significant heat., Mars is too far from the Sun for greenhouse gases to work., The red dust on the surface reflects all the heat back into space., Neptune is the coldest planet in the Solar System because it is the furthest from the Sun., TRUE, FALSE, A "Light Minute" is the distance light travels in one minute (approx. 18 million km). Earth is about 8.3 light minutes from the Sun. If Jupiter is 778.6 million km from the Sun, approximately how many light minutes away is it?, 8.3 minutes, 13.0 minutes, 43.2 minutes, 165.0 minutes, Jupiter is often called a "Gas Giant" because it has no solid surface; its atmosphere simply gets denser until it becomes liquid., TRUE, FALSE, You are building a scale model of the Solar System where 1 million km = 1 cm. In this model, the distance from the Sun to Earth is 150 cm. How far away would you need to place Saturn if its actual distance is 1,433.5 million km?, 14.33 meters, 1.43 meters, 143.3 meters, 15.0 meters
