2. La Terra és el tercer planeta del Sistema Solar, i de
moment, l’únic amb vida.
La Terra és un planeta terrestre, la qual cosa significa que és un cos
rocós, en lloc d'un gegant gasós com Júpiter. És el més gran dels
quatre planetes terrestres del sistema solar en mida i massa.
Presenta dos moviments: rotació i translació.
El moviment de
rotació origina els
dies i les nits.
El moviment de
translació origina
les estacions.
3. Capes de la Terra
Les capes terrestres són tres: Geosfera, Hidrosfera i Atmosfera.
La Geosfera es pot dividir en tres parts.
És la part rocosa del nostre planeta. Es
tracta d’una esfera d’uns 6.400km de
radi.
L’atmosfera és una barreja de
gasos: nitrogen, oxigen, vapor
d’aigua, diòxid de carboni i ozó.
Dividim l’atmosfera en dos capes
principals: troposfera i estratosfera.
4. L’escorça canvia
Les roques de l’escorça terrestre pateixen diferents processos que
fan canviar la seva escorça. Els fragments de roques i éssers vius
formen el sòl.
EROSIÓ: és el procés de trencament de les roques i on són retirades del lloc on
provenen per l’acció del vent o aigua.
TRANSPORT: és quan els materials erosionats es desplacen.
SEDIMENTACIÓ: els materials es dipositen i s’acumulen en un lloc.
7. L’energia de l’interior de la Terra fa que es produeixin
erupcions volcàniques i terratrèmols.
Un volcà és una obertura a l’escorça
terrestre per la qual el magma de
l’interior de la Terra surt a la superfície.
Quan el magma arriba a la superfície
s’anomena lava.
Els terratrèmols són moviments de
l’escorça terrestre, com ara tremors
o sacsejades. Es mesuren per
l’escala de Ritcher.
