Which of the following surfaces creates the most friction? question 4 options: gravel driveway ice skating rink bowling alley indoor basketball court

The correct answer would be 
A) Gravel driveway
This is the answer because if you have ever been to an ice skating rink, you know that you can glide quickly on it and if you fall, then you just continue sliding its basically a big waterside. In a bowling alley and an indoor basket ball court, most of the floors are probably waxed and your shoes don't have much of a grip on the floor. If you have ever fallen on a driveway, you would know that with the amount of force that you land on the driveway and the weight that is used, you create a lot of friction because of your skin rubbing against the driveway and you also have the marks to prove it! 
Hope this helps and have a wonderful day! :)
