ees exam 2nd qtr

• climate

  • composite pattern of long term weather condition that in a given region
  • refers to yearly cycles of temperature
• factors affecting climate

  • latitude
  • altitude
  • wind
  • albedo
  • oceans
  • humidity
• altitude

  • higher place, colder temperature latitude
  • amount of sunlight received
• equatorial latitude - different climate
• tropic region - not cold, not hot
• polar region - cold climate
• wind - transports heat and moisture
• oceans

  • transforms heat and moisture through ocean current
  • surface current
  • deep sea current - rivers under ocean
• climate of philippines

  • high temperature, high humidity, and abundant amount of rainfall
  • 2 pronoun seasons (dry and wet)
  • base on amount of rainfall and temperature and type of seasons
• climate change

  • mid to late 20th century
  • change in global regional
• measure climate

  • historical records
  • glacial evidence
  • tree riggs
  • plant pollen
  • rock and fossil records
  • changes in solar radiation
• interior parts of the earth - cosmic waves were used
• crust - continental and oceanic
• upper mantle - lithosphere and asthenosphere
• lower mantle - pure solid
• interior parts of the earth

  • crust
  • upper mantle
  • lower mantle
  • outer core
  • inner core
• crust

  • outermost, thinnest layer
• 2 parts of crust:

  continental crust

  oceanic crust
• continental crust

  • made up of granite igneous rocks.
  • about 20 - 70 km thick
• oceanic crust

  • dark and dense igneous rocks called basalt
  • 4 - 7 km thick
  • denser than continental
  • made up of silicate rocks like basalt and granite
• conrad / conrad discontinuity

  • boundary between oceanic and continental
  • transition zone
• moho boundary (mohorovicic discontinuity)

  • boundary of crust and mantle
• mantle

  • upper mantle
  • 3 sub layers
  • lower mantle
• 3 sub layers of mantle

  • asthenosphere
  • lithosphere
  • transition zone
• because of intense pressure, the plates move
• gutenberg discontinuity

  • mantle and core transition core
• mineralogist - person minerals
• mineralogy - study of mineral
• there is criteria to know if it is a mineral
• what is a mineral?

  • solid
  • inorganic
  • natural occurring
• criteria

  • inorganic
  • solid
  • natural occurring
  • polymorphism
• inorganic

  • do not contain carbon
  • exception to the rule if they have other four
  • has a definite chemical composition
  • atoms are arranged in orderly pattern
  • minerals have different sizes because of arrangement of atoms
• solid

  • execption to the rule if they have the other four
• natural occurring

  • made from nature
• polymorphism

  • ability of a specific chemical composition to crystalyze in more than one form
• physical properties of a mineral

  • color
  • luster
  • streak
  • hardness
  • cleavage
  • fracture
  • crystal
  • specific gravity
• special properties

  • fluorescence
  • magnetism
  • radio activity
  • phosphoresces
  • reactivity
  • smell
  • taste
  • double refraction
  • pizo electric
• color - most visible physical property of a mineral
• luster - ability of a mineral to reflect light
• reflect light, metallic

  do not reflect light, non metallic
