Read the paragraph below and answer the questions that follow.
(1) Street skateboarding and vert skateboarding differ in several ways. (2) Street skateboarding takes place in outdoor public areas where there are staircases, benches, walls, and sidewalks. (3) In contrast, vert skateboarding usually takes place in skate parks with ramps or bowls. (4) Another major difference is the tricks performed in each type of skateboarding. (5) Street skaters use a style called the grind, which involves scraping their boards' axles against objects such as stairway handrails. (6) They also perform tricks that involve kicking the board to flip it into the air. (7) Vert skaters, on the other hand, use the steep walls of the ramps or bowls to pick up speed and gain "air time" at the edges. (8) While airborne, they perform different flips and spins. (9) To achieve these tricks, they use boards that are wider and flatter than street boards, which have upturned noses and tails to aid kicking.
