Susunan[sunting | sunting sumber]

Lapisan-lapisan bumi

Planet bumi iku kesusun saking lapisan-lapisan:

Lapisan mantel bumi iku akèh banget jinisé. Sing jaba dhéwé biasa diarani mantel dhuwur. Lapisan paling njaba ing mantel dhuwur iki bareng kaliyan lapisan paling ngisor kerak bumi iku mbentuk lapisan litosfer. Ing ngisor litosfér iku ana lapisan astenosfer.

  1. ^ All astronomical quantities vary, both secularly and periodically. The quantities given are the values at the instant J2000.0 of the secular variation, ignoring all periodic variations.
  2. ^ Due to natural fluctuations, ambiguities surrounding ice shelves, and mapping conventions for vertical datums, exact values for land and ocean coverage are not meaningful. Based on data from the Vector Map and Global Landcover datasets, extreme values for coverage of lakes and streams are 0.6% and 1.0% of the earth’s surface. Note that the ice shields of Antarctica and Greenland are counted as land, even though much of the rock which supports them lies below sea level.
