    The crust can be thicker than 80 kilometers in some spots‚ less than one kilometer in others. Underneath it is the mantle‚ a layer of rock some 2700 kilometers thick that accounts for the bulk of the Earth. The crust is primarily made of granite and basalt while the mantle beneath is made of peridotite. More about all that below. How We Know the Earth Has a Crust Just a century ago‚ we didn’t know the Earth has a crust. Until the 1900s all we knew was that our planet wobbles in relation to the sky

    Review questions 1-10 Pages 146-147 1. Describe the three different kinds of material that can erupt from a volcano. Products of eruption come in three forms; lave flow‚ which can be Basaltic‚ Andesitic or Rhyolitic lava. A volcano also erupts pyroclastic debris (when lava flies into the air and freezes) and gases. 2. Contrast a pyroclastic flow with a lahar. Pyroglastic debris are blasting clots of lava‚ and the lahar are like mudslides that can reach up to 50km per hour. When the

    Igneous Textures Cooling rates influence igneous rock textures. Rapid cooling at the earth’s surface results in tiny mineral crystals that can only be seen under a microscope. The resulting extrusive igneous rocks have an aphanitic texture. Rocks that form as magma cools slowly underground (intrusive igneous rocks) develop phaneritic textures‚ in which individual mineral crystals can be seen without a microscope. Some igneous rocks exhibit visible crystals (phenocrysts) in a matrix of tiny

    EOSC 114: Volcanoes Notes from Web Notes Lesson 1: Why Do Volcanoes Have Different Characteristics? A. Formation of Lava Magma is formed by melting preexisting rock in Earth’s interior For magma to rise through crust it must be: (1)less dense than the crust (2) runny enough to flow (3) hot enough to stay liquid Magma that cools to form solid rock = lava B. Composition of Magma/Lava Magma is composed of various proportions of: Oxygen‚ Silicon‚ Aluminum‚ Iron‚ Calcium and Potassium Mineral –
