Paisagens Geológicas

Paisagens Geológicas

start

paisagem, afloramento e paisagem geológica

- paisagem: extensão de território que pode ser observado num determinado local até à linha do horizonte, constituida por elementos naturais e/ou humanos- afloramento: porção de rocha emergente da superfície do solo - paisagem geológica: paisagem cujo elemento predominante são as rochas

classificação de paisagens geológicas

paisagens sedimentares quimiogénicas (predomina o calcário ou evaporitos; grutas, algares, minas sal-gema, campos de lapiás)

paisagens sedimentares detríticas (predominam aglomerados de sedimentos; praias, dunas, ravinas, arribas, chaminés de fada)

paisagens magmáticas plutónicas (presença de granito; caos de blocos)

paisagens magmáticas vulcânicas (presença de basalto; cones vulcânicos, caldeiras, colunas de basalto)

paisagens metamórficas (presença de rochas muito deformadas, algumas delas com foliação (dobras, falhas, cristas quartzíticas)

geologia e petrologia

geologia: ciência que estuda a Terra (os seus materiais constituintes, a sua história e os processos que nela ocorrem)

Petrologia: ramo da geologia que estuda as rochas

Classificação das rochas

Rochas metamórficas - formam-se a partir da alteração de rochas preexistentes devido à ação da temperatura e pressão elevadas no interior da Terra - xistos e quartzitos

Rochas magmáticas - plutónicas (ou intrusivas) que se formam a partir do arrefecimento do magma no interior da terra (granito) - vulcânicas que se formam a partir do arrefecimento do magma à superficie (basalto)

Rochas sedimentares - detríticas (formam-se a partir de sedimentos de rochas preexistentes; arenito) - quimiogénicas (formam-se a partir da precipitação de constituintes dissolvidos na água; calcário) - biogénicas (formam-se a partir de restos de seres vivos; calcário recifal e carvão)

Constituição das rochas

as rochas são constituidas por diferentes minerais

- o granito (rocha) é constituito pelos minerais: 1. biotite 2. quartzo 3. feldspato

definição de mineral

mineralogia: ciência que estuda os minerais

mineral: - substância. sólida. natural. com estrutura cristalina. inorgânica. com composição química definida

propriedades dos minerais

como se identifica um determinado mineral?

1. cor 2. dureza 3. traço 4. brilho 5. clivagem/fratura 6. outras específicas (sabor, cheiro, magnetismo e efeverscência)

cor

. cor vísivel do mineral . tem pouco valor classificativo porque há minerais com cores diferentes . a olivina tem cor verde mas o quartzo pode ter diversas cores

traço ou risca

'cor do mineral reduzido a pó

utiliza-se uma placa de porcelana

a cor do traço pode ser diferente da cor do mineral - a hematite tem cor cinza mas a cor do seu traço é vermelho terroso

brilho

reflexo da luz no mineral

. pode ser metálico ou não metálico (nacarado ou vítreo) . o cobre tem brilho metálico (semelhante ao dos metais) . o talco tem um brilho nacarado (semelhante ao das pérolas . a olivina tem brilho vítreo (semelhante ao dos vidros)

clivagem ou fratura

forma como o material se parte

moscovite- clivagem (origina superfícies planas) quartzo- fratura (parte-se de forma irregular)

+info

dureza

- resistência de um mineral a ser riscado- utiliza-se a escala de Mohs (de 1 a 10)

propriedades específicas

- a halite sabe a sal - o enxofre tem um cheiro muito específico - a magnetite atrai os ímanes - a calcite reage com os ácidos fazendo efeverscência

To tell stories in an organized, hierarchical, structured, and concise manner. These are the four pillars for carrying out a successful presentation.

'Your content is liked, but it engagesmuch more if it is interactive' - Genially

Pose a question or problem that makes the class think; it is the essential ingredient to maintain their attention. It is usually raised at the beginning of the topic to encourage critical thinking and participation.

• Plan the structure of your content.
• Give visual weight to key points and main ones.
• Define secondary messages with interactivity.
