Why does water move to the top of tall trees?

There are three ways the water will reach the top of a tree 
Capillary action: water is attracted to the sides of small tubes and can pull its way up through the xylem vessels 
Root pressure: water absorbed by the plants in the roots pushes water up the xylem vessels 
Transpiration: water is attracted to itself , and so when water evaporates from the leaves at the top of the plant, water is further pulled up 

We can use solar powered cars or ride bikes instead of cars that burn fossil fuels
