Question

Why are there gaps between railway tracks?

~pls help , i have a science exam coming up tmr T-T

Answer 1

Hope the below helps!

Step-by-step explanation:

Metal expands when hot, so the rails expand in the summer.

The gap is provided to allow for this expansion. If no gap is left, the expansion in summer will cause the rails to bend sideways. That will result in train accidents.

P.s - Good luck in the exam tomorrow :)
