Problem: -  The brain tells blood vessels to dilate - The sweat glands become active - Moisture is released from the pores - The moisture evaporates - The evaporation causes cooling.  What might be the first step of the process?

A: Body temperature rises


Problem: -  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?

A: Gases cause pressure beneath the earth


Problem: -  The wind and water pick up sediment that came off the rocks - Sediment is carried to an area by the wind, water, air, or ice - Sediment is deposited on the same spot many times - The sediment piles on top of other sediment for a long time - The sediment near the bottom is compressed by the weight of newer sediment - The sediment becomes sedimentary rock as it is pushed together by the heavy weight -   What might be the first step of the process?

A: Wind and water erode rocks


Problem: -  The items are sorted - Trash is removed from everything else - Goes to a landfill - The items go into a baler machine for each kind of material - They come out as bales - The bales are shipped to manufacturers to use to make products.  What might be the first step of the process?
