Question

Which four planets are inner planets? List their properties.

Answer 1

The four inner planets are Mercury, Venus, Earth, and Mars.

Step-by-step explanation:

The Inner Planets:

1. Mercury: Mercury is the closest planet to the Sun and is the smallest planet in the solar system. It has a very thin atmosphere and no moons.
2. Venus: Venus is often called Earth's 'sister planet' because of its similar size and composition. It has a thick atmosphere made mostly of carbon dioxide and experiences a runaway greenhouse effect, making it the hottest planet in the solar system.
3. Earth: Earth is the third planet from the Sun and the only known planet to support life. It has a diverse ecosystem and a protective atmosphere that allows for the existence of liquid water.
4. Mars: Mars is often called the 'Red Planet' because of its reddish appearance. It has a thin atmosphere and ancient riverbeds, suggesting that liquid water once flowed on its surface.
