P\u0103m\u00e2ntul este cea mai mare dintre cele patru planete st\u00e2ncoase din Sistemul nostru Solar. Este foarte greu pentru dimensiunile sale. \u00cen centrul s\u0103u se afl\u0103 un nucleu mare, bogat \u00een fier, unde temperatura ajunge la 6000 de grade Celsius \u2013 la fel de fierbinte ca suprafa\u021ba Soarelui.<\/p>\n<\/div>\n

Miezul exterior lichid se agit\u0103 pe m\u0103sur\u0103 ce planeta se rote\u0219te, func\u021bion\u00e2nd ca un dinam de biciclet\u0103. Acest dinam face ca P\u0103m\u00e2ntul s\u0103 se comporte ca un magnet puternic.<\/p>\n

Form\u00e2nd o bul\u0103 invizibil\u0103 \u00een jurul planetei, c\u00e2mpul magnetic al P\u0103m\u00e2ntului ac\u021bioneaz\u0103 ca un scut. Acesta protejeaz\u0103 planeta de majoritatea particulelor de mare vitez\u0103 aruncate \u00een spa\u021biu de furtunile solare. Uneori, particulele str\u0103pung bariera \u00een apropierea polilor magnetici. Acest fenomen d\u0103 na\u0219tere aurorelor terestre \u2013 cunoscute \u00een mod obi\u0219nuit sub numele de aurora boreal\u0103 \u0219i aurora austral\u0103.<\/p>\n

Suprafa\u021ba P\u0103m\u00e2ntului este protejat\u0103 \u0219i de atmosfera dens\u0103. Aceasta blocheaz\u0103 cea mai mare parte a radia\u021biilor nocive provenite din spa\u021biu. De asemenea, face ca obiectele mici care p\u0103trund \u00een atmosfer\u0103 s\u0103 ard\u0103, transform\u00e2ndu-se \u00een stele c\u0103z\u0103toare. Doar meteori\u021bii \u0219i cometele mai mari ajung la suprafa\u021b\u0103 \u0219i explodeaz\u0103, l\u0103s\u00e2nd \u00een urm\u0103 cratere mari.<\/p>\n

Spre deosebire de Lun\u0103 \u0219i de alte planete rocose, pe P\u0103m\u00e2nt exist\u0103 ast\u0103zi pu\u021bine cratere de impact. Majoritatea au fost erodate sau umplute de ac\u021biunea apei curg\u0103toare, a v\u00e2ntului \u0219i a ghe\u021bii.<\/p>","protected":false},"excerpt":{"rendered":"
