Screws have things called threads and when you twist them into something, they get stuck inside. They work best with wood.
Answer
The thread on a screw allows it to PULL itself into say a piece of wood. No pressure is needed on the screw driver, just to turn it will be sufficient. The screw does all the work.
no
With a longer spanner, there is more leverage so it is easier to screw or unscrew things.
a screw works better cues it has threads and a nail is just goes straight in the board. The nail is stronger but the screw holds tighter.
You insert the point into an appropriate screw and rotate the handle clockwise to screw in and the opposite to screw out.
Since tree trunks are made of wood, you can put a wood screw into them if you wish. It is always easier to screw in a screw if you drill a guide hole first.

dik,
It is easier. The question is not complete enough to be answered. The word EASIER needs to be further defined. so the question should read: What is easier to [add information here]; more screw threads or less screw threads?
A screw with fewer threads has a larger distance between each thread, which reduces the friction and resistance encountered when driving it into wood. This design allows for easier penetration as there is less material being displaced with each turn of the screw. Additionally, fewer threads mean that the screw can be driven in more quickly, making it easier for the user to apply force effectively. Overall, this simplifies the process of fastening the screw into the wood.
The hole into which a screw is inserted is called a pilot hole. This hole helps to guide the screw into the material and prevent it from splitting or cracking. It also makes it easier to drive the screw in.
A screw makes your life better by helping you to accomplish things thy you couldn't do by hand
A screw that screws into a screw works by using its threads to grip onto the existing screw and create a secure connection. The threads on the screw being inserted match the threads on the existing screw, allowing them to twist together and hold in place.
