Ziemia jest najwi\u0119ksz\u0105 z czterech planet skalistych w naszym Uk\u0142adzie S\u0142onecznym. Jak na swoje rozmiary jest bardzo ci\u0119\u017cka. W jej centrum znajduje si\u0119 du\u017ce j\u0105dro bogate w \u017celazo, w kt\u00f3rym temperatura si\u0119ga 6000 stopni Celsjusza \u2013 tyle samo, ile na powierzchni S\u0142o\u0144ca.<\/p>\n<\/div>\n

P\u0142ynny rdze\u0144 zewn\u0119trzny wiruje wraz z obrotem planety, dzia\u0142aj\u0105c niczym dynamo w rowerze. To w\u0142a\u015bnie dzi\u0119ki temu dynamu Ziemia zachowuje si\u0119 jak silny magnes.<\/p>\n

Pole magnetyczne Ziemi, tworz\u0105c niewidzialn\u0105 ba\u0144k\u0119 wok\u00f3\u0142 planety, dzia\u0142a jak tarcza. Chroni to planet\u0119 przed wi\u0119kszo\u015bci\u0105 cz\u0105stek poruszaj\u0105cych si\u0119 z du\u017c\u0105 pr\u0119dko\u015bci\u0105, wyrzucanych w przestrze\u0144 kosmiczn\u0105 przez burze s\u0142oneczne. Czasami cz\u0105stki te przebijaj\u0105 si\u0119 przez t\u0119 barier\u0119 w pobli\u017cu biegun\u00f3w magnetycznych. Powoduje to powstawanie z\u00f3rz polarnych \u2013 powszechnie znanych jako zorza polarna p\u00f3\u0142nocna i po\u0142udniowa.<\/p>\n

Powierzchnia Ziemi jest r\u00f3wnie\u017c chroniona przez g\u0119st\u0105 atmosfer\u0119. Blokuje ona wi\u0119kszo\u015b\u0107 szkodliwego promieniowania z kosmosu. Sprawia r\u00f3wnie\u017c, \u017ce ma\u0142e obiekty wpadaj\u0105ce w atmosfer\u0119 spalaj\u0105 si\u0119, tworz\u0105c spadaj\u0105ce gwiazdy. Tylko wi\u0119ksze meteoryty i komety docieraj\u0105 do powierzchni i eksploduj\u0105, pozostawiaj\u0105c po sobie du\u017ce kratery.<\/p>\n

W przeciwie\u0144stwie do Ksi\u0119\u017cyca i innych planet skalistych, na Ziemi obecnie znajduje si\u0119 niewiele krater\u00f3w uderzeniowych. Wi\u0119kszo\u015b\u0107 z nich uleg\u0142a erozji lub zosta\u0142a wype\u0142niona przez dzia\u0142anie p\u0142yn\u0105cej wody, wiatru i lodu.<\/p>","protected":false},"excerpt":{"rendered":"
