đọc đoạn văn và trả lời câu hỏi From far out in space, Earth looks like a blue ball. Since water covers three-fourths of the Earth's surface, blue is the color we see most. The continents look brown, like small islands floating in the huge, blue sea. White clouds wrap around the Earth like a light blanket. The Earth is shaped like a sphere, or a ball. It is 25,000 miles around! It would take more than a year to walk around the whole planet. A spaceship can fly around the widest part of the sphere in only 90 minutes. Even though spaceships have traveled to the Moon, people cannot visit the Moon without special suits. The Moon has no air or water. Plants and animals can't live there either. Astronauts first landed on the Moon in 1969. After that, there were six more trips to the Moon. They brought back Moon rocks, which scientists are still studying. There are holes, or craters, all over the Moon's surface. Scientists believe that meteorites smashed into the Moon millions of years ago and formed the craters. CÂU HỎI 1, can plants and animals live there ? 2, what does Earth look like from far out in space ? 3, it the earth shaped like a sphere ? 4, according to the scientists , what formed the craters ?
