Sezvo Wenyika chinoumba akaumba: sechivako redu

Kuti redu nemi mukati? Sei akaumba paro paNyika, mune dzimwe dzekare sei zvichiitika? nyaya dzose idzi vagara ainetseka pamusoro pavanhu. Uye masayendisiti akawanda vaida kuziva kuti munzvimbo dzakadzika? Asi wakatendeuka kuti kudzidza zvose izvi hazvisi nyore kudaro. Kunyange nhasi, yose zvamazuva ano ose mhando tsvakurudzo, pasi pesimba revanhu kuti vanochera matsime kupinda muura chete makiromita anenge gumi nemashanu - ndikasazovapo. Uye dzizere uye nzwisisika ruzivo achida kudzika kuva hurongwa zvikuru zvikuru. Naizvozvo, masayendisiti uye kuti kufunga kuti Earth yakaumbwa musimboti, uchishandisa dzakasiyana-siyana soro-zvakarurama zviridzwa.

The kudzidza Earth

Kubvira kare, vanhu vakadzidza pamatombo pachena takasununguka. Mawere uye neyemitenusirwa gomo, mawere menzizi kumakungwa ... Pano unogona pachako, zvakavapo, zvichida mamiriyoni emakore akapfuura kuchengeta bedrock. Uye mune mamwe nzvimbo yakakodzera vari akachera matsime. Chimwe chezvinhu hwakarongwa izvi - iri pamusoro Kola Peninsula. udzamu Its - gumi nezviviri mamita. Mine kuti vanhu kupaza kuna migodhi, kunogonawo kubatsira kudzidza womukati nemamiriro Earth. Core, Chokwadi, ivo "kuwana" asingagoni. Asi ezvimbambaira izvi uye matsime, masayendisiti anogona dzosa dombo ivhu, vachiziva saizvozvo pamusoro kuchinja dzavo uye matangiro, mamiriro uye akafanana. Zvishoma nzira idzi kuti vanokwanisa kuongorora chete nyika uye chete yokumusoro chikamu goko paNyika.

Recreating mararamiro Wepasi chinoumba

Asi pasina kuonana dawo masayendisiti zvakadzama uye zvakadzama zviri kubatsira geophysics uye seismology - sayenzi kwenyika uye Geological Kuronga nyika. Nokuongorora zvizivikanwe nemichina nemafungu uye kuparadzirwa yavo zvinoitika, uye chii chiri jasi uye chinoumba (kunotsanangurwa zvakafanana Somuenzaniso, murwiyo meteorites). Zivo yakadaro kunobva mashoko vakawana - zvisina kunanga - pamusoro ehupfumi kuti zvinhu zvenyama. Uyewo nhasi, ari kudzidza kunoita kuti magetsi Data vakawana kubva satellites ari muchadenga.

Sechivako mapuraneti

Masayendisiti vaigona kunzwisisa, nokupfupikisa zvakabudiswa, kuti nemamiriro Nyika yakaoma. It rine zvishoma matatu dzisakarurama zvikamu. Pakati duku chinoumba dzinoitwa rakakura nejasi. The jasi iri vanenge shanu-sixths ari zvachose vhoriyamu Pasi. Uye pamusoro ose cover vakanaka mutete chokunze goko Nyika.

Sechivako musimboti

Core - nechepakati, pakati chikamu. Rakakamurwa dzakawanda akaturikidzana: nechinzwano zvekunze. Maererano nenyanzvi dzakawanda ano, yomukati chinoumba zvikukutu, uye kuruvanze - mvura (riri yakaumbwa state). Uye chinoumba rinorema kwazvo: nayo anoyera zvinopfuura chetatu vazhinji panyika panguva Vhoriyamu pfuurei 15. Chinoumba tembiricha iri nani yakakwirira, zviri kubva 2,000 kusvika 6,000 Celsius. Under zvekungofungira nemasayendisiti, center Dzenyika rinoumbwa simbi uye nickel iri huru. The nharaunda iri inorema chidimbu - 3470 makiromita. A pose nharaunda dzinenge mamiriyoni 150 mativi makiromita, riri pamusoro akaenzana nzvimbo mumakondinendi ose pamusoro pepasi.

Sezvo Wenyika chinoumba akaumba

Information pamusoro chinoumba redu iri dikisa, uye rinogona kuwanikwa chete isina kunanga (hapana chinoumba mimwe mabwe). Naizvozvo, dzidziso kungaratidzwa chete zvokufungidzira nezvekuti paNyika chinoumba aumba. Nhoroondo Earth ane mabhiriyoni emakore. Masayendisiti vanoomerera dzidziso kuti nyika akatanga kuumbwa kuva hwakanaka homogenous. Muitiro allocating kuti tsanga vakatanga pashure. A chayo - nickel nedare. Sezvo Wenyika chinoumba aumba? The uchanyangadika nesimbi zvishoma nezvishoma kunotangira nechepakati yepasi, achiumba musimboti. Izvi zvakaitika nokuda hombe imwe nhamba yacho uchanyangadika.

dzimwe pfungwa

Panewo vavengi dzidziso iyi, kutungamirirwa, ndiko musoro nharo. Chekutanga, masayendisiti ava zvinombokunetsa chokwadi kupfuura imwe chiwanikwa yedare nickel ari makirisito centre (100 kilometers). Chechipiri, kana tichifungidzira kusarudzwa nickel nedare silicates, meteor kwakadaro ipapo ikaitika uye yakakodzera rutapudzo zvakaitwa. Iyewo, zvakateverwa nokubudiswa hombe kwazvo okisijeni, pova kumanikidzwa mazana anoverengeka zviuru atmospheres. Asi uchapupu ariko kare Nyika muchadenga saka inoshayikwa. Naizvozvo yaiswa mberi dzidziso yepakutanga paumbwe chinoumba panguva paumbwe nyika.

Muna 2015, kuti Oxford vasayendisiti uye vose vakabayira dzidziso kuti chinoumba kwakaitwa nyika inoumbwa uranium exchange uye ane radioactivity. Izvi zvisina kunanga kunoratidza kuvapo yakadaro refu uye remagineti Nyika, uye kuti mazuva ano, nyika yedu anoratidza zvakawanda kupisa pane kutarisirwa hypotheses apfuura zvesayenzi.
