时间怎样划分的？
1、凌晨是指0点到6点。2、早上是指6点11点。3、中午是指11点13点。4、下午是指13点18点。5、傍晚是指18点20点。时间的概念：当一个点相对于某坐标系运动时，其运动所形成的直线或线段或曲线就是相对于该坐标系静止的点的时间之一。每个点对应多个时间。相对于某一个时间，静止的点开始运动速度越快时间越慢，当速度与该时间中运动的点一样时时间停止，速度超越该点时相当于正回到过去。扩展资料：世界时间是通过天体测量来测量的，由于各种因素的影响，相对于原子会有微小的误差。为了协调世界时间和原子时，科学家们正在处理协调世界时间。世界时间秒以下数字的协调是以原子时数据为基础的。当世界时与原子时的差达到一秒时，就会出现跳跃的第二秒或负跳跃的第二秒。古时一天分12个时辰，采用地支作为时辰名称，并有古代的习惯称法。时辰的起点是午夜。古代使用铜壶滴漏计时，以下漏击点为名。一更分为五点，所以，一点的长度合24分钟。参考资料来源：百度百科-时间百度百科-凌晨百度百科-早上百度百科-中午百度百科-下午百度百科-傍晚百度百科-晚上

时间是如何划分的？
根据您的问题，我猜测您询问的是时间的划分方式。以下是一些常见的时间划分方式：1. 秒、分、时、天、周、月、年：这是根据时间长短进行的时间划分，是人们日常生活中最常用的时间划分方式。2. 古代时间名称：在中国古代，人们使用更多的时间名称，如刻、更、鼓、点等，来描述具体的时间。3. 二十四小时制：这种方式将一天分成两个12小时的区间，以12小时为界，一天中的时间名称有所不同。4. 十二小时制：这种方式也将一天分成两个6小时的区间，但以6小时为界，一天中的时间名称与二十四小时制有所不同。5. 时刻、时段、小时、日、周、月、年：这是根据时间的长短和连续性进行的时间划分，常常用于交通运输、计划管理等方面。这些是一些常见的时间划分方式，还有其他更加详细和复杂的时间划分方式，如太阳时、太阴时、真太阳时、假太阳时等等。
请回答地理问题高中
9.D
根据题目推论，此时当地地方时应为12：00，而当地与北京的时差大约7小时。
10.C
首先，黄河站不是北极点，选C的理由是此时是由极夜转为有昼夜交替现象的首个日出，说明是太阳刚好升起，就得落下。当地时间为12：00，此时太阳正好位于黄河站的正南方
11 .B
根据太阳回归运动黄河站刚好出现昼（即极夜现象结束）的日期是3月9日，离春分日有12天。根据对称原理，也就是说到了秋分日12天以后黄河站刚进入极夜现象，日期为10月2日以后。故11选题选B。
