  • What is the normal?
    It is a ray that is incident at 90 degrees to a surface.
  • Whats the difference between REFLECTION and REFRACTION?
    reflection happens when the image appears in the same direction as when the wave comes, while refraction is when it “changes” the position.
  • What are the zones from the ocean?
    Intertidal zone, continental zone, estuary and oceanic zone
  • What is one of the changes that El Niño causes?
    The water temperatures increases changing the precipitations ratios and disturb the fish industry
  • How does the water that is on the surface get to the aquifers?
    The water goes down and passes through soil, making the water clean, until it gets to the aquifer
  • What are the two types of adaptations animals make to get used to small or large quantities of water during the year?
    Physical and behavioral changes
  • How does the light travel?
    In a straight line
  • What mirror creates a virtual image and shrinks it?
    Convex mirrors
  • What are the most important uses of water?
    Agriculture, industries and eletricity
  • If the angle incidence in a plane mirror is 70°, what would be the angle of reflection?
    70°
  • Our eyes are concave lenses. True or false?
    False, they are convex lenses.
  • The reflection of light off a shiny, smooth surface is...
    ...specular reflection
  • What is the biggest watershed in the world?
    Amazon river watershed
  • What is a translucent object?
    An object that only part of the light can pass through it.
  • What is the natural phenomena in which the Pacific Ocean water cools?
    La Niña
  • Explain the water cycle.
    evaporation + evapotranspiration → condensation → precipitation → runoff
  • What is the name used in the water cycle to describe rain ?
    Precipitation
  • Water always flows in one direction which is…
    Down / Gravity
  • What is the name given to the line in which the ground encounters the first aquifer or ground water?
    Water table
  • In what part of the water cycle is when the water comes from nature (trees/plants)?
    Evapotranspiration
  • What’s the pupil’s function?
    Its function is to control the amount of light that gets in the eye.
  • What are ocean currents?
    An ocean current is a continuous, directed movement of sea water generated by a number of forces acting upon the water, including wind, temp. and salinity.
  • How does a wave is formed?
    The wind can force the water to have a snail movement the deeper the weaker this movement stays, until it loses itself
  • How can water pollution affect the life of all living things?
    It can pollute the water making a lot of animals and organisms that are not adapted die
