The planets of Nova offer a fascinating glimpse into our solar system's diversity. Each planet, with its unique characteristics, beckons the curious minds of space enthusiasts. This article is dedicated to uncovering Nova's Planets Inner Worlds Worksheet Answers, enabling you to delve deeper into the mysteries of our cosmic neighborhood without spending hours scouring through textbooks or online resources.
Mercury: The Swift Messenger
Mercury, the closest planet to the Sun, holds several unique features:
- Orbit: With the shortest orbital period, Mercury completes its orbit in just 88 Earth days.
- Surface Features: Impact craters, steep cliffs called scarps, and a lack of atmosphere define its surface.
- Extreme Temperatures: Mercury experiences temperatures as high as 800°F (430°C) during the day and as low as -290°F (-180°C) at night due to no atmosphere to regulate heat.
Venus: Earth’s Sister
Venus, often referred to as Earth’s twin, presents a paradoxical environment:
- Thick Atmosphere: Composed mainly of carbon dioxide, it’s significantly thicker than Earth’s, leading to a greenhouse effect.
- Retrograde Rotation: Venus rotates on its axis in the opposite direction to most planets.
- Volcanic Activity: Evidence suggests there could be recent volcanic activity, altering its surface.
Earth: The Blue Planet
Earth, unique in its support for life, boasts:
- Hydrosphere: About 71% of its surface is covered by water.
- Geologic Activity: Plate tectonics, which play a significant role in shaping the planet’s geography.
- Protective Atmosphere: A balanced atmosphere with oxygen, nitrogen, and other gases fosters life.
Mars: The Red Planet
Mars, with its red hue, is the next on our journey:
- Ice Caps: Both polar regions have ice caps made of frozen water and dry ice (frozen carbon dioxide).
- Volcanoes: Olympus Mons, the largest known volcano in the solar system, resides here.
- Canyons: Valles Marineris, one of the largest canyon systems, stretches for thousands of kilometers.

🪐 Note: This table provides only a snippet of each planet’s characteristics. Further exploration will yield even more intriguing details.
Understanding these inner worlds of Nova isn't just about academic achievement; it's about expanding our perspective of the universe. From Mercury's swift orbit to Mars' grand canyons, each planet teaches us about the forces that shape planets and, by extension, possibly how life could exist elsewhere.
What makes Mercury unique among the inner planets?
+Mercury is unique for its extremely short orbital period, its extremely hot and cold temperatures, and its lack of atmosphere. This combination results in a planet that presents an environment unlike any other in our solar system.
Why is Venus known as Earth’s sister planet?
+Venus is similar to Earth in size, mass, density, and composition, but its thick atmosphere, retrograde rotation, and extreme surface conditions make it a stark contrast to Earth’s livable conditions.
How does Earth’s water coverage support life?
+Water on Earth serves as a medium for life, regulating temperature, providing a habitat, and aiding in nutrient cycling, making it essential for life as we understand it.
