Attributes of the Inner Planets

The video explores the four inner planets: Mercury, Venus, Earth, and Mars. Mercury, closest to the sun, has a thin atmosphere and extreme temperature variations. Venus, similar in size to Earth, is the hottest planet due to its dense carbon dioxide atmosphere. Earth, the only planet with life, has a diverse environment and a protective atmosphere. Mars, known as the Red Planet, has two moons and is explored by rovers. Each planet's unique features, such as Mercury's craters, Venus's volcanoes, Earth's hydrosphere, and Mars's iron oxide surface, are discussed.
