普化考題CH17-4,17-5(地質系)

1.An active volcano emits gases, liquids, and solids. Please write down the
  two main gases spewed into the atmosphere.

2.All molecular vibrate. To vibrate more energetically, a molecule must
  absorb a photon of a specific wavelength in the IR region. Please show the
  three different ways of vibration of water.

3.The recent volcanic eruption in Iceland (Eyjafjallajokull volcano) is
  stranding hundreds of thousands of air travelers at Heathrow Airport and
  other airports across northern Europe, due to its voluminous clouds of
  volcanic ash that can clog airplane engines and limit visibility . Which two
  of the following statements about volcano are correct ?

  (A) Volcanoes are all found in places where tectonic plates are diverging
      (e.g. Iceland) or converging (e.g. Pacific Ring of Fire).
  (B) Rhyolitic magma is always more viscous than basaltic magma. Viscosity of
      a magma depends on the temperature and composition (especially the silica
      and dissolved-gas contents).
  (C) Andesitic magmas are erupted by approximately 80 percent of volcanoes
      worldwide (e.g. Mount St. Helens).
  (D) Magma is formed by partial melting of upper mantle and crust. Its
      temperature range from 10000o to 12000oC.
  (E) Volcanic eruptions may inject aerosols into the Earth's atmosphere.
      Large injections may cause global climate change, mainly lowering the
      temperature of the earth's surface.


ANSWERS

(1) CO2, and H2O.

(2) (課本p.783,Figure17.14)

(3)ANS:(B)(E)

(A) Volcanoes are all found in places where tectonic plates are diverging
(e.g. Iceland) or converging (e.g. Pacific Ring of Fire). →(hot spot)

(C) Andesitic magmas are erupted by approximately 80 percent of volcanoes
worldwide (e.g. Mount St. Helens). →( basaltic magma)

(D) Magma is formed by partial melting of upper mantle and crust. Its
temperature range from 10000 o to 12000 o C. →(1000o to 1200oC. )

大家看看還有沒有問題吧
第三題一定要補充
陳承我把第三題選項砍掉一個喔...不然跟第一題重複

有意見建言的還請趕快提出喔~謝謝大家<(_ _)>
