  • 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 most important uses of water?
    Agriculture, industries and eletricity
  • 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.
  • Water always flows in one direction which is…
    Down / Gravity
  • 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 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 is the natural phenomena in which the Pacific Ocean water cools?
    La Niña
  • The reflection of light off a shiny, smooth surface is...
    ...specular reflection
  • What are the zones from the ocean?
    Intertidal zone, continental zone, estuary and oceanic zone
  • What is the name given to the line in which the ground encounters the first aquifer or ground water?
    Water table
  • Explain the water cycle.
    evaporation + evapotranspiration → condensation → precipitation → runoff
  • If the angle incidence in a plane mirror is 70°, what would be the angle of reflection?
    70°
  • In what part of the water cycle is when the water comes from nature (trees/plants)?
    Evapotranspiration
  • What is the biggest watershed in the world?
    Amazon river watershed
  • 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
  • Our eyes are concave lenses. True or false?
    False, they are convex lenses.
  • What mirror creates a virtual image and shrinks it?
    Convex mirrors
  • What is a translucent object?
    An object that only part of the light can pass through it.
  • What’s the pupil’s function?
    Its function is to control the amount of light that gets in the eye.
  • What is one of the changes that El Niño causes?
    The water temperatures increases changing the precipitations ratios and disturb the fish industry
  • What is the normal?
    It is a ray that is incident at 90 degrees to a surface.
  • 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
  • What is the name used in the water cycle to describe rain ?
    Precipitation
  • How does the light travel?
    In a straight line
