The answer is refraction. When a wave from one medium enters another medium, its direction changes due to the change of speed (phase velocity changes but frequency remains the same). The wave slows down when it enters a denser medium from the one it came from hence its path seems to bend.

Match each property with the benefit it provides to people on Earth. A. magnetic field filters cancer-causing rays from the sun
vodomira [7]

The correct matching are the following:

  • A. magnetic field: prevents charged particles from the sun from reaching the surface
  • B. ozone: filters cancer-causing rays from the sun
  • C. carbon dioxide: retains heat energy from the sun in the atmosphere
  • D. water in oceans, lakes, rivers and streams: moderates changes in temperature on the surface

The electromagnetic field of the Earth protects us from solar wind by deflecting it. Without it, the charged particles would strip away our ozone, which will lead to the end of life on Earth.

The ozone is a layer in the stratosphere that filters the suns rays. It filters the UV rays by absorbing it. This prevents the UV rays from damaging the surface of the Earth.

Carbon dioxide retains heat in the atmosphere, which creates a greenhouse effect. It is beneficial for us, but because human activity like industrial activities emit so much carbon in the atmosphere that it ends up being harmful.

Bodies of water found on Earth regulate the temperature of the Earth through ocean currents. It brings in both cold and warm air to land which also affect precipitation.

Long explanation, I know, but maybe this will help you out in the long run. Good Luck!
