no, sometimes i don't hit the ground when I'm doing an ollie but you don't do as high :)
I can imagine that if it can crawl up on the skateboard and hit the ground or a surrounding then it can ride a skateboard.
A skateboard should be used by pushing hard on the ground.
When a funnel cloud touches the ground it becomes a tornado.
...he exerts against the ground
friction
Tornadoes that are on the ground are simply referred to as tornadoes.

yes if his hand touches the ground he is down but only if he is touched by contact and then touches the groundNo. A player is down only when a part of his body other than a hand or a foot touches the ground, or when the officials rule that his forward progress has been stopped.
A funnel cloud that touches the ground is a tornado.
an ollie is a way of getting to a higher ground. basically like if you were bmxing and were going to do a bunny hop except with a skateboard.
The main forces acting on a moving skateboard are friction with the ground, air resistance, and the force applied by the skater to propel the skateboard forward. Additionally, there may be gravitational forces affecting the vertical motion of the skateboard.
