How do electrons flow through a wire
aniked [119]

Every atom has electrons. When you add new electrons to the wire, they will be passed on to an atom. The electrons keep passing from atom to atom until it reaches the light source, basically. It's kinda like that one song "100 jugs of milk" or whatever it's called. Each atom passes the atom next to it an electron.

How does upwelling affect the weather of a coastal region?
SIZIF [17.4K]

c.The warm surface water results in moist air and more rainfall.

Explanation:

  • During upwelling, cold water in the ocean is stirred up and brought to the surface.
  • The warmer surface water is then taken into deeper parts of the ocean.
  • Upwelling allows for nutrient mixing in the ocean and allows for useful gases to circulate well.
  • The warm surface water causes the air to be moisty.
  • When the air is carried landward towards the coast, it leads to rainfall when the saturated air releases the water.
  • The air then becomes cold and dry and it rises up.
  • Therefore, warm surface water results in moist air and more rainfall.
