 VOLCANO

A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface

SUNSET CRATER IS A CINDER CONE VOCANO
Mauna Loa IS A SHEILD VOLCANO


  • TYPES OF VOLCANOES
  • stratovolcano (or composite volcano) — a conical volcano consisting of layers of solid lava flows mixed with layers of other rock
  • cinder cone volcano — doesn’t have any horizontal layers, and is instead a steep conical hill of tephra (volcanic debris) that accumulates around and downwind from the vent.
  • shield volcano —  a type of volcano built entirely or mostly from fluid lava vents. They are named like this because when viewed from above, you can see just how massive and imposing they are – like a warrior’s shield.
SUPERVOLCANO
An unusually large volcano having the potential to produce an eruption with major effects on the global climate and ecosystem.

Submarine volcanoes are underwater vents or fissures in the Earth's surface from which magma can erupt. A large number of submarine volcanoes are located near areas of tectonic plate movement, known as mid-ocean ridges.

                              MINERALS  Andalusite   Andalusite is an aluminium nesosilicate mineral with the chemical formula Al₂SiO₅. Andalusite is trimorphic with kyanite and sillimanite, being the lower pressure mid temperature polymorph. Anhydrite   Anhydrite is a mineral—anhydrous calcium sulfate, CaSO₄. It is in the orthorhombic crystal system, with three directions of perfect cleavage parallel to the three planes of symmetry   Apatite   Apatite is a group of phosphate minerals, usually referring to hydroxylapatite, fluorapatite and chlorapatite, with high concentrations of OH−, F− and Cl− ions, respectively, in the crystal Arsenopyrite   Arsenopyrite is an iron arsenic sulfide. It is a hard metallic, opaque, steel grey to silver white mineral with a relatively high specific gravity of 6.1. When dissolved in nitric acid, it releases elemental sulfur Augite   Augite is a common rock-forming pyroxene mineral with formula (Ca,Na)(Mg,Fe,Al,Ti)(S

Geological time, relative dating and radiometric dating

  age of earth t  the  age of the Earth  is approximately 4.54 ± 0.05 billion  years  (4.54 × 10 9  years ± 1%). This dating is based on evidence from radiometric- age dating   of meteorite    material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples Geological processes Geological processes are dynamic processes at work in the earth's landforms and surfaces. The mechanisms involved,  weathering ,  erosion , and  plate tectonics , combine processes that are in some respects destructive and in others constructive. relative dates based on cross-cutting relationship s Cross - cutting relationships   is a principle of geology that states that the geologic feature which  cuts   another is the younger of the two features. It is a relative dating technique in geology. There are several basic types of cross cutting relationships: Structural relationships may be  faults  or  fractures  cutting through an older rock.

Origin, composition and internal structure of the earth

process of the  formation of the solar system Solar system formed about 4.6 billion year ago, when gravity pulled together low-density cloud of  interstellar  gas and dust (called a nebula)(movie). The Orion Nebula, an  interstellar cloud in which star systems and possibly planets are forming. Solar System Formation. Scientists believe that the solar system was formed when a cloud of gas and dust in space was disturbed, maybe by the explosion of a  nearby  star (called a supernova). This explosion made waves in space which squeezed the cloud of gas and dust. Earth Differentiation .  After the initial formation of protoplanets, remaining gas and dust was gradually blown away by the solar wind during the  heat -up phase of the young sun. At that time our  earth was probably a barren planet, pockmarked by meteorite bombardment, and may have looked on the surface like the Moon.   composition and characteristics of the core, mantle and crust The solid, inner  core  of iron has
