  1. Energii neimblanzite Cutremurele Vulcanii

  2. Cutremurele • Def.-zguduituri puternice ale scoartei terestre. • Cauze-deplasarea si ciocnirea placilor tectonice • -vulcanismul • - inchiderea periodica a vulcanilor in magma solidificata • Elementele unui cutremur: • A) hipocentru (focar) –locul de formare a cutremului. • B) epicentru -corespondentul la suprafata al hipocentreului. • Efecte– pagube materiale • - obiective industriale • - pierderi de vieti umane si animale • -tzunami

  3. Cutremurele

  4. Urmarile cutremurelor

  5. Vulcanii • Def. 1-vulcanism-totalitatea fenomenelor legate de eruptiile vulcanilor. • 2-magmatism-totalitatea fenomenelor legate de migrarea si consolidarea magmei in interiorul scoartei. • Fenomene vulcanice: • 1 – fenomenele intrusive – au loc in interiorul scoartei • 2 – fenomenele extrusive – cele care au loc la suprafata scoartei • Produsele vulcanice – vapori de apa • - ape termale • - coloane tasnitoare de apa • - cenusa vulcanica • - fragmente de roca vulcanica • - lava dupa dioxid de siliciu- bazice • - acide

  6. Elementele vulcanilor: cos, con, basin magmatic, crater, lava • 1- Relieful volcanic de explozie: cratere- simple • - caldeire- cratere largite prin eroziune si prabusiri • -maare- explozii de gaze si vapori de apa • 2- Relieful vulcanic de acumulare: • - con - platouri • 3- Relieful vulcanic de eroziune: • - in crater - retea hidrografica radiar convergenta • - pe con – retea hidrografica radiar divergenta • - la baza conului- retea hidrografica inelara

  7. Explozii vulcanice

  8. Urmarile vulcanilor
