G. Competency/Case-Based Questions (CBQs)

The following questions are case-based. Read the case carefully and answer the questions that follow.

The Sun is the center of our solar system, with the Earth orbiting around it. Beyond Earth, comets originate from the outer reaches of the solar system. Our solar system is part of the vast Milky Way galaxy, home to billions of stars. Within the galaxy, asteroids are found in orbit around the Sun, often between Mars and Jupiter. These small rocky objects offer clues to the solar system’s formation. Comets, on the other hand, are icy bodies that release gas and dust as they approach the Sun. The Earth passes through trails of comet debris, creating spectacular meteor showers. The Milky Way galaxy stretches across the night sky, a reminder of our place in the universe. Asteroids and comets provide insights into the early days of our solar system. The Sim’s gravity holds our celestial neighborhood together.
