SHAKLHOI ASOSII RELEFI SATHI ZAMIN

SHumo medoned, ki qishri Zamin az du qism iborat ast:

1.Barjastagihoi matsriki (khushky).

2. Hamii qariuqyonusi.

Sathi onho  az pastiyu balandihoi gunogunshakl va gunogunmiqyos iborat ast. Hamai onho  pasty va balandihoi sathi khushki (materikho) va hamii qari uqyonushoro tashkil medihand. Ammo relefi khushki va qari uqyonusho ba gunogunshaklii khud nigoh nakarda, bo yakdigar shabohat va umumiyat dorand. In jihathoro ba hisob girifta, dar khushki va qari ukyonusho du shakli asosii relefro farq menamoyand: kuhho va hamvoriho.

Paydoishi onho  ba harakathoi qishri Zamin vobasta ast. Dar natijai in harakatho dar Zamin va kari uqyonusho chinlorshavi, kafidan, kandashavii qabatho, hosilshavii vulqonho, zilzila va ohista pastu balandshavii qabathoi qishri Zamin rukh medihad. On kuvvahoero, ki baroi ba vujud omadani in khodisaho sabab shudaand, quvvahoi dokhilii (endogenii) Zamin meguyand. Onho  ba jamshavi, harorat, tabdilyobi va harakati moddahoi dokhili Zamin vobastaand. Tasiri in quvvakho asosan dar paydoishi kuhho va vulqonho  zohir megardad.

Dar natijai faoliyati in hodisaho avvalin nohamvorikhoi sathi Zamin ba vujud meoyaid. Dar qismhoi alohidai sathi Zamin nohiyahoi vasei kuhsor, khamiho paydo meshavand. Barobari paydo shudani kuhho va khamiho dar yak vaqt ba onho  kuvvahoe tasir merasonand, ki kuhhoro vayron, khamihoro bo jinshoi kukhii tahshiny pur mekunand. Ba on quvvaho garmii oftob, kharakati bod.

Borishot, kharakati piryakh, obhoi ravon, faoliyati organizmho (nabotot va hayvonot) dokhil meshavand. Hamai onhoro quvvahoi berunii (ekzogenii) Zamin menomand. In quvvahoi beruni bo quvvakhoi dokhilii Zamin dar yak vaqt payvasta amal mekunand. Dar natijai in on nohamvorihoero, ki kuvvahoi dokhilii Zamin ba vujud ovardaand, quvvahoi berunii Zamin hamvor mekunapd. In amaliyoti mutaqobilai quvvahoi dokhili va beruni sababi gunogunii relefi hozirai sathi qishri Zamin gardidaast. Onho  az kuhhoi baland, khamvorihoi vase, vodii daryoho, soyu, jariho, teppa, adiru khamiho va sufakuhho iborat meboshand.
