Hurricanes form in tropical waters between 8 and 20 degrees north and south of the  equator. Hurricanes rarely form at higher latitudes because the water is too —

b) Convection, because the spoon was in contact with the cold ice cream
c) Conduction, because cold air currents affected the temperature of the spoon
d) Convection, because cold air currents affected the temperature of the spoon

Students performed several trials using the laboratory setup shown. Students were  also given this hypothesis: If friction increases, then the rolling distance of a marble  will decrease. What should be changed to best test this hypothesis?
a) Height of the ramp
b) Height and length of the ramp
c) Roughness of the ramp surface
d) Height of the ramp and roughness of the ramp surface
