Further information: Topographical areas of Yorkshire and Geology of Yorkshire

Yorkshire was not a homogeneous natural or topographical area and the contrasting conditions and natural resources led to differences in the way that the different areas of the county developed over time. These differences manifested themselves in contrasting economic developments as well as the styles of the vernacular architecture of the various areas.The North York Moors area is even now very different from the South Yorkshire Coalfield area of West Riding and this differs greatly from Holderness.

In Yorkshire there is a very close relationship between the major topographical areas and the underlying geology. The Pennine chain of hills in the west is of Carboniferous origin. The central vale is Permo-Triassic. The North York Moors in the north-east of the county are Jurassic in age while the Yorkshire Wolds to the south east are Cretaceous chalk uplands.

The region is drained by several rivers. In Western and central Yorkshire the many rivers empty their waters into the River Ouse which reaches the North Sea via the Humber Estuary.

The most northerly of the rivers in the Ouse system is the Swale, which drains Swaledale before passing through Richmond and meandering across the Vale of Mowbray. Next, draining Wensleydale, is the River Ure, which joins the Swale east of Boroughbridge. The River Nidd rises on the edge of the Yorkshire Dales National Park and flows along Nidderdale before reaching the Vale of York.

The Ouse is the name given to the river after its confluence with the Ure at Ouse Gill Beck. The River Wharfe, which drains Wharfedale, joins the Ouse upstream of Cawood. The Rivers Aire and Calder are more southerly contributors to the River Ouse and the most southerly Yorkshire tributary is the River Don, which flows northwards to join the main river at Goole. In the far north of the county the River Tees flows eastwards through Teesdale and empties its waters into the North Sea downstream of Middlesbrough. The smaller River Esk flows from west to east at the northern foot of the North York Moors to reach the sea at Whitby.

The River Derwent rises on the North York Moors, flows south then westwards through the Vale of Pickering then turns south again to drain the eastern part of the Vale of York. It empties into the River Ouse at Barmby on the Marsh. To the east of the Yorkshire Wolds the River Hull flows southwards to join the Humber Estuary at Kingston upon Hull. The western Pennines are served by the River Ribble which drains westwards into the Irish Sea close to Lytham St Anne's.
