一天永远会是24小时吗?10多亿年前,地球的一天只有18个小时,地球自转越来越慢,今天的一天是24小时,据科学家估算,在遥远的未来,地球上的一天将会是960小时!而10亿年前,月球离地球更近,那时一个月才20天。目前,月球正以每年4厘米的距离远离地球。●地球的表面积是多少?地球的表面积是51010万平方公里。●地球内部温度有多高?每向地球里面走1公里,其温度就会增加20摄氏度,据科学家推算,在地球的中心地区,温度高
One day will always be 24 hours? More than 1 billion years ago, Earth’s day is only 18 hours, the Earth’s rotation is getting slower and slower, and today’s day is 24 hours. According to scientists, in the distant future, one day on Earth It will be 960 hours! And a billion years ago, the moon was closer to Earth, then 20 days a month. At present, the moon is moving away from the earth at a distance of 4 cm per year. ● What is the surface area of the earth? The surface area of the earth is 510.10 million square kilometers. ● How high is the temperature inside the earth? Every 1 km to the earth, the temperature will increase by 20 degrees Celsius. According to scientists’ calculations, in the center of the earth, the temperature is high
