"Which planet is known as the Red Planet?",
"Venus is often called Earth's twin because of its similar size and proximity.\nMars, known for its reddish appearance, is often referred to as the Red Planet.\nJupiter, the largest planet in our solar system, has a prominent red spot.\nSaturn, famous for its rings, is sometimes mistaken for the Red Planet."

"What causes seasons on Earth?",
"The tilt of Earth's axis causes different parts of the planet to receive varying amounts of sunlight throughout the year.\nThe moon's gravitational pull affects ocean tides but not seasons.\nEarth's orbit around the sun is slightly elliptical, but this has minimal effect on seasons.\nThe rotation of Earth on its axis causes day and night cycles."
