-  Some is reflected back into space - The rest of the energy is absorbed by land and oceans, heating the Earth - Heat radiates from Earth to space - Some of this heat is trapped by greenhouse gases in the atmosphere - Human activities such as burning fuel are increasing the amount of greenhouses gases - This causes more heat radiation to stay trapped in our atmosphere - The Earth's temperature rises -   What might be the first step of the process?
----
Answer: Solar radiation reaches Earth's atmosphere


-  The gases come to a head and push molten magma to the surface - The magma cools - With enough time the pressure builds up greatly - The resulting volcano may explode.  What might be the first step of the process?
----
Answer: Gases cause pressure beneath the earth


-  You fill the tray with warm water - You carefully place the tray on an even surface in a freezer that is at least 32 degree Farhenheit, the freezing point of water - The water begins to get colder until it starts to freeze solid - The water expands as it freezes, one of the few liquids that has greater volume as a solid - Because you used warm water, the gasses in the water had evaporated out, so you will have nice clear ice cubes without cracks from the trapped gasses -   What might be the first step of the process?
