Take note that the United Kingdom is composed of four countries which are England, Wales, Northern Island, and Scotland. England is just one country. This means that in terms of landmass, they are different. The UK is obviously bigger because there are four countries that are part of it.
Take note that they also make use of different flags. The flag of England is known to be Saint George’s Cross, while the flag of England is called The Union Flag. The way that they have gotten their names are also different from each other. With these details, it will be easy to not get confused with their differences again.
