During the last ice age the bank was part of a large landmass connecting Europe and the British Isles, now known as Doggerland. It has long been known by fishermen to be a productive fishing bank; it was named after the doggers, medieval Dutch fishing boats especially used for catching cod.

At the beginning of the 21st century, the area was identified as a potential site for the UK round 3 wind farm, being developed as Dogger Bank Wind Farm.

The history of rail transport in Great Britain to 1830 covers the period up to the opening of the Liverpool and Manchester Railway, the world's first intercity passenger railway operated solely by steam locomotives. The earliest form of railways, horse-drawn wagonways, originated in Germany in the 16th century.

The atmosphere is composed mainly of nitrogen and oxygen, which make up about 99 per cent of clean, dry air. Nitrogen 78 per cent, oxygen 21 per cent and other gases like carbondioxide, argon and others comprise 1 per cent by volume. 

In the given options, ionosphere and ozonosphere are included in atmosphere.  Ionosphere consists of ions due to ultra violet radiations causing photo ionization and hence forming ionosphere. Ozonosphere is also called as stratosphere which consists of ozone gases that prevents UV rays from entering the earth’s surface. On the other hand lithosphere is not a layer of atmosphere but it is a hard surface consisting of rocks on earths surface.

Layer of atmosphere which absorbs UV light radiations is known as ozonosphere. It is a region of Earth's stratosphere. This region contains high concentrations of ozone in comparison to other parts of the atmosphere. Ozonosphere is mainly found in the lower portion of the stratosphere. This layer protects earth from harmful UV light radiations.

The atmosphere of Earth is composed of nitrogen (about 78%), oxygen (about 21%), argon (about 0.9%), carbon dioxide (0.04%) and other gases in trace amounts.
