Subsidence is a general term for downward vertical movement of the Earth's surface, which can be caused by both natural processes and human activities. Subsidence involves little or no horizontal movement, which distinguishes it from slope movement.

Processes that lead to subsidence include dissolution of underlying carbonate rock by groundwater; gradual compaction of sediments; withdrawal of fluid lava from beneath a solidified crust of rock; mining; pumping of subsurface fluids, such as groundwater or petroleum; or warping of the Earth's crust by tectonic forces. Subsidence resulting from tectonic deformation of the crust is known as tectonic subsidence and can create accommodation for sediments to accumulate and eventually lithify into sedimentary rock.

Sir Richard Arkwright (23 December 1732 – 3 August 1792) was an English inventor and a leading entrepreneur during the early Industrial Revolution. He is credited as the driving force behind the development of the spinning frame, known as the water frame after it was adapted to use water power; and he patented a rotary carding engine to convert raw cotton to 'cotton lap' prior to spinning. He was the first to develop factories housing both mechanised carding and spinning operations.

Arkwright's achievement was to combine power, machinery, semi-skilled labour and the new raw material of cotton to create mass-produced yarn. His organisational skills earned him the accolade "father of the modern industrial factory system," notably through the methods developed in his mill at Cromford, Derbyshire (now preserved as part of the Derwent Valley Mills World Heritage Site).

Derby (/ˈdɑːrbi/ DAR-bee) is a cathedral city and unitary authority area on the River Derwent in Derbyshire, England. Derbyshire is named after Derby, which was its original county town. As a unitary authority, Derby is administratively independent from Derbyshire County Council. The population of Derby is 274,149 (2024).

The Romans established the town of Derventio, which was later captured by the Anglo-Saxons and then by the Vikings who made Djúra-bý one of the Five Boroughs of the Danelaw. Initially a market town, Derby grew rapidly in the industrial era and was home to Lombe's Mill, an early British factory and it contains the southern part of the Derwent Valley Mills World Heritage Site. With the arrival of the railways in the 19th century, Derby became a centre of the British rail industry. Despite having a cathedral since 1927, Derby did not gain city status until 1977.
