The Earth ta juyawa

A juyawar duniya a kusa da axis da rãnã ci gaba. Mutane da yawa mamaki dogara ne a kan wannan yunkuri. Saboda haka, da rana ya bi dare, daya kakar wani, a fagage daban-daban kafa daban-daban sauyin yanayi.

Daily juyawar duniya, bisa ga masana kimiyya, ne 23 hours, 56 minutes da kuma 4,09 seconds. Saboda haka akwai daya cikakken bi da bi. Tare da gudun game da 1670 km / hour sa duniya motsi a kusa da axis. By sandunan gudun an rage wa sifili.

Man ba ga juyawa daga cikin Duniya. Wannan shi ne saboda gaskiyar cewa dukan abubuwa da suke kusa da shi, motsa lokaci guda kuma a cikin layi daya da guda gudun.

Juyawa daga cikin Duniya a kusa da Sun ne da za'ayi a cikin falaki. An located a kan wani kirkirarren surface wucewa ta cikin cibiyar na duniya da kuma haske star. Wannan surface ake kira da orbital jirgin sama.

Ta hanyar da tsakiyar duniya wuce kirkiran line tsakanin sandunan - axis. Wannan layin da orbital jirgin sama ne ba perpendicular. Karkatar axis ne kamar daidai 23.5 digiri. The girma na son yi kwana ne ko da yaushe guda. The line kusa da Earth motsa, ko da yaushe tilted zuwa daya gefen.

Orbiting duniya daukan wani shekara. The Earth ta juyawa ne to za'ayi counterclockwise. Ya kamata a lura da cewa kewayewa ne ba daidai madauwari. A talakawan nesa ga Sun ne game da ɗari da hamsin da miliyan kilomita. Yana (da nesa) an canza ta an talakawan na uku da miliyan kilomita, forming haka da kadan orbital m.

Yawa a duniya kewayewa ne 957 Mill. Km. Wannan nisa ne da duniyar da nasara da ɗari uku da sittin da biyar kwana, shida hours, minti tara da tara da rabi seconds. Kamar yadda aka kiyasta, juyawa daga cikin Duniya a sarari suKe faruwa a gudun kilomita 29 da biyu.

Masana kimiyya sun gano cewa, da motsi na duniya da aka slowing. Wannan shi ne saboda yafi tidal braking. A surface na duniya a ƙarƙashin rinjayar da janye watã (mafi yawa) da kuma Sun kafa tidal shafts. Su matsawa daga gabas zuwa yamma (bayan wadannan basamaniyai), a gaban shugabanci to shugabanci na duniya tamu.

Kadan muhimmancin ne a haɗe zuwa tides a Duniya ta lithosphere. Kamar wancan akwai wani nakasawa da wani m jiki a cikin nau'i na dama jinkirta tidal kalaman. Yana tsokani braking karfin juyi da cewa taimaka wa gaskiya cewa Duniya ta juyawa ne slowing sauka.

Ya kamata a lura da cewa a cikin lithosphere tides tasiri cikin braking aiwatar duniya kawai 3%, da sauran 97% zo daga tides. Wadannan bayanai da aka samu a da kafa tãguwar ruwa katunan Lunar da kuma hasken rana tides.

A kan tsoma da kuma na yanayi dabam dabam gudun duniya. An dauke da babban hanyar yanayi da hawa da sauka a cikin motsi na duniya. Movement of yanayi na faruwa daga gabas zuwa yamma a cikin ƙananan latitudes kuma daga yamma zuwa gabas - a high kuma matsakaici latitudes. A wannan yammacin iskõki lokacinta tabbatacce, yayin da gabashin iskõki da korau, ya kiyasta cewa sau da dama kasa da na farko. Wannan bambancin da aka sake rabawa tsakanin Duniya da sararin sama. Tare da kara iska yammacin ko na gabashin weakening a yanayi mai kusurwa lokacinta ƙaruwa da kuma rage-rage a kusa da Duniya. Saboda haka, tashin na duniya da aka slowing. A karfafa da kuma raunanar da gabashin iskõki yammacin, bi da bi, a wani yanayi rage lokacinta. Saboda haka, ya zama sauri yunkuri na Duniya. A total kusurwa lokacinta a cikin yanayi da kuma duniya ne a darajar canzawa.

Masana kimiyya sun iya sanin cewa tsawon kwanakinka kwanaki kafin 1620 ya faru wani talakawan of 2.4 ƴan daƙiƙa a shẽkara ɗari. Bayan haka, da darajar rage ta kusan rabin kuma ya fara zama 1.4 ƴan daƙiƙa a shẽkara ɗari. Duk da haka, a cewar wasu 'yan kimomi da kuma lura da Duniya inda hakan shi ya auku a wani talakawan of 2.25 ƴan daƙiƙa a shẽkara ɗari.
