Deriva Continental E TectóNica de placas litosféricas

  1. 1. Deriva dos Continentes e Tectónica de placas Isabel Lopes
  2. 2. Teoria da Deriva dos Continentes Alfred Wegner (1915) publicou “A origem dos Continentes e dos Oceanos” Defendeu que os continentes eram constituídos por materiais menos densos que flutuavam sobre materiais mais densos que constituíam os fundos oceânicos. IL 2010 2
  3. 3. Pangeia e Pantalassa – Wegner admitiu que à cerca de 245 M.a existia apenas 1 super continente – Pangeia, e um super oceano - Pantalassa IL 2010 3
  4. 4. Pangeia e Pantalassa – Há 80 M.a. Pangeia fragmentou-se nos continentes na Laurásia e na Gondwana. – Desde há 70 M.a. A América do Sul começou a separar-se de África, e os restantes continente foram tomando as posições hoje conhecidas IL 2010 4
  5. 5. Contornos ajustáveis entre a borda oriental da América do Sul e a costa ocidental de África IL 2010 5
  6. 6. Correspondência entre as rochas que encontrou em ambos os lados do oceano Atlântico (tipo, natureza e estrutura) IL 2010 6
  7. 7. Fósseis dos mesmos seres vivos (animais e plantas) em locais (continentes) actualmente distantes IL 2010 7
  8. 8. Presença de glaciares Paleoclimatologia: ciência que estuda os antigos climas da Terra. Ex.: Presença de glaciares (clima frio) e carvão (clima quente) IL 2010 8
  9. 9. Não conseguiu convencer… • Os geofísicos e os geólogos da altura não ficaram convencidos de que os continentes se mexessem! Que forças poderiam deslocar massas tão gigantescas? Para Wegner:  O movimento de rotação da Terra  Força das marés IL 2010 9
  10. 10. Teoria da Tectónica de Placas Em 1950 com a exploração dos fundos oceânicos e com o estudo do magnetismo das rochas voltou o interesse… Nova Teoria (baseada na teoria de Wegner): Divide a Litosfera em placas que se movimentam IL 2010 10
  11. 11. Constituição Interna da Terra Litosfera = Crusta + Manto superior IL 2010 11
  12. 12. Constituição Interna da Terra Como saber? Exploração dos fundos oceânicos*: Zonas de dorsal, no centro das quais estão os riftes (saída de magma) * através de Barcos com sondas IL 2010 12
  13. 13. Placas litosféricas IL 2010 13
  14. 14. Placas litosféricas IL 2010 14
  15. 15. Constituição Interna da Terra Como saber? Magnetismo das rochas: Algumas contém minerais de ferro que quando arrefecem ficam orientados de acordo com o campo magnético terrestre Campo magnético alterou-se ao longo IL 2010 da História da Terra 15
  16. 16. Movimento das Placas Tectónicas IL 2010  16
