Geology
Historically, the northern boundary of Yorkshire was the River Tees, the eastern boundary was the North Sea coast and the southern boundary was the Humber Estuary and Rivers Don and Sheaf. The western boundary meandered along the western slopes of the Pennine Hills to again meet the River Tees. It is bordered by several other historic counties: the county of Durham, Lincolnshire, Nottinghamshire, Derbyshire, Cheshire, Lancashire and Westmorland. In Yorkshire there is a very close relationship between the major topographical areas and the geological period in which they were formed. 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.
