1. Why can Near-Earth Asteroids be dangerous for Earth?
=> Because they orbit the Sun, crossing Earth's orbit, they can occasionally collide with Earth, causing destruction. Therefore, Near-Earth Asteroids can pose a threat to Earth.2. Give a reason why comets are gradually destroyed when they come close to the Sun multiple times.
=> When comets come close to the Sun multiple times, the ice, dust particles, rock fragments, and gases in them gradually get destroyed, leading to the eventual destruction of the comet.3. Why do most meteors burn up and get destroyed?
=> Most meteors are very small, so due to friction in the atmosphere, they burn up and get destroyed.
4. write about Big Bang Theory.
=> The Big Bang theory is a scientific theory about the origin and development of the universe. According to this theory, the universe originated around 13.8 billion years ago. Initially, it existed in an extremely small, hot, and dense state (a singularity). From this state, a massive explosion, known as the Big Bang, occurred.After the Big Bang, the universe expanded rapidly, leading to the formation of energy, matter, and eventually various stars, planets, galaxies, and other celestial bodies. This expansion process is still ongoing, which scientists have confirmed through various observations, cosmic microwave background radiation, and the movement of galaxies.
This theory helps us understand the origin, structure, and expansion of the universe, and it is regarded as a fundamental theory in modern astronomy.
