Merry-go-round, Earth and train are interrelated!

Science teacher at school explained why trees grown along the sides of railway track seem to 'run' back as one travels in a train. But I did not expect at that time that that explanation and my realisation will help me later in life to understand easily a mega event that happens daily! What is it?

A crawling wonder on back!

At school, as boys we used to play on its sandy ground. Then we were often stunned by feeling some creature crawling up between our shirt and the back. As soon as we understood it to be a 'biting ant' we pulled out our shirts and brushed away this ant - to avoid its agonizing bite.
