When you ride a bicycle, how does the ground provide a reaction force?

Urgent will mark brainliest!

1. The tires go round and round in order to move.

2. The ground provides gravity on the bike to make it go and stay on the ground.

Step-by-step explanation:

1. The tires provide an action force by going round and round when someone puts force on the pedals and the gears turn and therefore makes the tires go round and round in order to make the bike move.

2. The ground provide a reaction force because the earth's core has a gravitational pull that pulls down on the bike to the ground so it's not just floating around and if the person is providing action force on the bike and tires to make it go, the ground makes a path and therefore the bike goes to any location that the person wants to go.
