Ques: Answer the following question given this paragraph: Near-Earth asteroids have orbits that cross Earth's orbit. This means that they can collide with Earth. There are over 4,500 known near-Earth asteroids. Small asteroids do sometimes collide with Earth. An asteroid about 510 m in diameter hits about once per year. Five hundred to a thousand of the known near-Earth asteroids are much bigger. They are over 1 kilometer in diameter. When large asteroids hit Earth in the past, many organisms died. At times, many species became extinct in a mass extinction. Astronomers keep looking for near-Earth asteroids. They hope to predict a possible collision early so they can to try to stop it. Q: Near-earth asteroids cross paths with earth, meaning they could collide; what are the paths called? Choices: - trajectory - curves - galaxies - orbits A:
Ans: orbits

Answer the following question given this paragraph: If someone asks you, "What is science?" you might say that it's a bunch of facts and explanations. But that's only part of the story. Science is a knowledge base. But science is also a way of learning about the world. Earth science is about our planet and its environments. Earth scientists study Earth's surface and interior. They study why volcanoes erupt and why some places are mountainous and some are entirely flat. Some Earth scientists are interested in the weather. Others want to know about the oceans. There are even Earth scientists who apply what they know about Earth to learning about space. Some Earth scientists do a lot of their work in the field, as seen above. Q: What branch of science aims to understand all about our planet and its environments? Choices: - biology - immunology - petrology - earth science A:
(A).
earth science
