You will test three different skate park ramp designs that meet the following criteria:

the skate park playground ramp must include at least one loop.
the skate park playground ramp must rest on the ground.
the skater must complete a successful run from one side of the ramp to the other without falling off the ramp.

the answer is tropical areas. the tropical areas obtain more

radiant energy from the sun than they lose to space through terrestrial

radiation, and vice versa for polar areas. earth has an energy remaining in the

tropics and an energy scarcity for the polar areas.
