![]() ![]() To demonstrate this estimate, Phinney used a computer to calculate where 1,000 hypothetical particles would go if ejected from Earth in random directions. Moreover, even if Earth rocks were freed by meteorite impact, Mars’s orbit is much larger than Earth, So Phinney estimates that the probability of these rocks hitting Mars is about one-tenth asgreat as that of Mars’s rocks hitting Earth. Phinney, kicking a rock hard enough to free it from Earth’s gravity would require a meteorite capable of making a crater more than 60 miles across. This conclusion has led to another question whether meteorite impacts on Earth have similarly driven rocks from this planet to Mars. ![]() Your answers to these items should be based on the passages only.Recently some scientists have concluded that meteorites found on Earth and long believed to have a Martian origin might actually have been blasted free of Mars’s gravity by the impact on Mars of other meteorites. Read the following 1 Passage and answer the items that follow. In summary, the term Goldilocks Zone refers to the region around a star where the conditions are just right for the existence of liquid water on the surface of a planet, and it is important in the search for Earth-like planets outside our solar system. Some of the most promising candidates for supporting life are located within this zone. In recent years, advances in technology have allowed scientists to detect and study exoplanets (planets outside our solar system) and determine whether they are within the Goldilocks Zone. The Goldilocks Zone is determined by various factors such as the size and temperature of the star, the distance between the planet and the star, and the composition of the planet's atmosphere. The concept of the Goldilocks Zone is important in the search for Earth-like planets outside our solar system, as it is believed that liquid water is a key ingredient for the development of life as we know it. This zone is not too hot or too cold, but just right, like the porridge in the story of Goldilocks and the Three Bears. The Goldilocks Zone, also known as the habitable zone, refers to the region around a star where the conditions are just right for the existence of liquid water on the surface of a planet.
