[Q]: Process: - A photovoltaic cell is created with two layers of semiconductor material - The top layer are &#x27;doped&#x27; with impurities to allow a negative charge - The bottom layer are &#x27;doped&#x27; to allow for a positive charge - This produces an electric field that allows electrons to flow from negative to positve - Sunlight enters the cell - Energy from sunlight knocks electrons loose in both fields - This prevents the flow of electrons from negative to positive - Adding an external circuit allows the exchange to continue - Give the cells owner a flow of electricity.  Question: suppose dishes a well rinsed happens, how will it affect more sunlight available.  - A: more - B: less - C: no effect
****
[A]: C


[Q]: Process: - Water gets into cracks in rocks - The water freezes into ice - The cracks expand - Over time the rocks split - The rocks are now in smaller pieces.  Question: suppose more water freezes into ice happens, how will it affect LESS or SLOWER weathering occurring.  - A: more - B: less - C: no effect
****
[A]: A


[Q]: Process: - Electromagnet creates magnetic field with electricity - Conductive copper wire is wrapped around a piece of metal - An electric current gets introduced from power source - Flows through the wire - Magnetic field gets created in the wire - And the metal gets magnetized - When turned off it is no longer magnetic.  Question: suppose less current flows through wire happens, how will it affect a WEAKER electromagnet.  - A: more - B: less - C: no effect

[A]: A


[Q]: Process: - Water is heated - The heated water evaporates - The salt is left behind - The evaporated water condenses on a cold surface - The evaporated water is collected - The process is repeated - More salt is removed from the water.  Question: suppose there is not much water available happens, how will it affect a lesser volume of water is heated.  - A: more - B: less - C: no effect
