Bu katmanlardan en d\u0131\u015fta bulunan ve ya\u015famaya elveri\u015f olana kabuk ad\u0131 verilmektedir. T\u00fcm canl\u0131 ya\u015fam\u0131n\u0131 \u00fczerinde bulunduran, o bu katman\u0131n ortalama kal\u0131nl\u0131\u011f\u0131 30 km kadard\u0131r. Kabu\u011fun hemen alt\u0131ndan ba\u015flay\u0131p \u00e7ekirde\u011fe kadar devam eden tabakaya manto ad\u0131 verilir. 5100 km derinli\u011fe kadar inen manto tabakas\u0131n\u0131n kabu\u011fa yak\u0131n olan b\u00f6l\u00fcm\u00fc k\u0131r\u0131lgan kayalardan olu\u015fmaktad\u0131r.

Manto tabakas\u0131ndaki bas\u0131n\u00e7 nedeni ile erime noktalar\u0131 y\u00fckselen demir ve magnezyum kat\u0131 halde bulunurlar. D\u00fcnyan\u0131n merkezini olu\u015fturan \u00e7ekirdek ise %90 oran\u0131nda s\u0131v\u0131 demirden olu\u015fmaktad\u0131r. Bunun nedeni \u00e7ekirdekte tahminen 3 milyon Atm olan bas\u0131n\u00e7 alt\u0131nda demirin erime noktas\u0131n\u0131n 8000 C\u00b0’yi bulan \u00e7ekirdek \u0131s\u0131s\u0131ndan d\u00fc\u015f\u00fck olmas\u0131 olarak a\u00e7\u0131klaya biliriz.
