Physical geography is one of the three main branches of geography. Physical geography is the branch of natural science which deals with the processes and patterns in the natural environment such as the atmosphere, hydrosphere, biosphere, and geosphere. This focus is in contrast with the branch of human geography, which focuses on the built environment, and technical geography, which focuses on using, studying, and creating tools to obtain, analyze, interpret, and understand spatial information. The three branches have significant overlap, however.
Geomorphology is the scientific study of the origin and evolution of topographic and bathymetric features generated by physical, chemical or biological processes operating at or near Earth's surface. Geomorphologists seek to understand why landscapes look the way they do, to understand landform and terrain history and dynamics and to predict changes through a combination of field observations, physical experiments and numerical modeling. Geomorphologists work within disciplines such as physical geography, geology, geodesy, engineering geology, archaeology, climatology, and geotechnical engineering. This broad base of interests contributes to many research styles and interests within the field.
The physiographic regions of the contiguous United States comprise 8 divisions, 25 provinces, and 85 sections. The system dates to Nevin Fenneman's report Physiographic Divisions of the United States, published in 1916. The map was updated and republished by the Association of American Geographers in 1928. The map was adopted by the United States Geological Survey by publication in 1946.
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins.
Regional geography is one of the major traditions of geography. It focuses on the interaction of different cultural and natural geofactors in a specific land or landscape, while its counterpart, systematic geography, concentrates on a specific geofactor at the global level.
Richard John Chorley was an English geographer, and Professor of Geography at Cambridge University, known as leading figure in quantitative geography in the late 20th century, who played an instrumental role in bringing in the use of systems theory to geography.
The geographic cycle, or cycle of erosion, is an idealized model that explains the development of relief in landscapes. The model starts with the erosion that follows uplift of land above a base level and ends, if conditions allow, in the formation of a peneplain. Landscapes that show evidence of more than one cycle of erosion are termed "polycyclical". The cycle of erosion and some of its associated concepts have, despite their popularity, been a subject of much criticism.
The following outline is provided as an overview of and topical guide to Earth science:
Morphotectonics, or tectonic geomorphology, is a branch of geomorphology that studies how landforms are formed or affected by tectonic activity. Morphotectonists seek to understand the deep Earth mechanisms behind the creation of tectonic landforms by processes such as crust uplift, subsidence, faulting, or folding.
Professor Sidney William Wooldridge CBE, FRS, FGS, geologist, geomorphologist and geographer, was a pioneer in the study of the geomorphology of south-east England and the first professor of geography at King's College London. He collaborated with Dudley Stamp and with David Linton.
Geography is the study of the lands, features, inhabitants, and phenomena of Earth. Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. Geography has been called "a bridge between natural science and social science disciplines."
Marjorie Mary Sweeting, was a British geomorphologist specializing in karst phenomena. Sweeting had gained extensive knowledge on various topographies and landscapes by travelling around the world to places such as Greece, Australia, Czechoslovakia, United States, Canada, South Africa, Belize, and most notably China. She published Karst Landforms, and Karst in China: its Geomorphology and Environment. The latter is the first comprehensive Western account of China's karst, and one of the first western published works on the karst found within China, despite being a male dominated field.
The British Society for Geomorphology (BSG), incorporating the British Geomorphological Research Group (BGRG), is the professional organisation for British geomorphologists and provides a community and services for those involved in teaching or research in geomorphology, both in the UK and overseas. The society’s journal, Earth Surface Processes and Landforms is published by Wiley-Blackwell and online access is available free to members. The society is affiliated with the Royal Geographical Society as an affiliated research group and with the Geological Society of London as a specialist group.

In climatic geomorphology, morphoclimatic zones are areas which are characterised by landforms associated with a particular climate. The geomorphological processes involved with distinct climates can have large impacts on the near-surface geology of the area.
Periglaciation describes geomorphic processes that result from seasonal thawing and freezing, very often in areas of permafrost. The meltwater may refreeze in ice wedges and other structures. "Periglacial" originally suggested an environment located on the margin of past glaciers. However, freeze and thaw cycles influence landscapes also outside areas of past glaciation. Therefore, periglacial environments are anywhere when freezing and thawing modify the landscape in a significant manner.
Eiju Yatsu was a Japanese geomorphologist who taught in Japan, US and Canada. He is best known for his contributions to weathering and 'rock control' in geomorphology.
Climatic geomorphology is the study of the role of climate in shaping landforms and the earth-surface processes. An approach used in climatic geomorphology is to study relict landforms to infer ancient climates. Being often concerned about past climates climatic geomorphology considered sometimes to be an aspect of historical geology. Since landscape features in one region might have evolved under climates different from those of the present, studying climatically disparate regions might help understand present-day landscapes. For example, Julius Büdel studied both cold-climate processes in Svalbard and weathering processes in tropical India to understand the origin of the relief of Central Europe, which he argued was a palimpsest of landforms formed at different times and under different climates.
Heather Viles is a professor of biogeomorphology and heritage conservation in the school of geography and the environment at Oxford University, senior research fellow at Worcester College, and honorary professor at the Institute of Sustainable Heritage, University College London. She is a Fellow of the British Society for Geomorphology.
Nevin Melancthon Fenneman was an American professor of geology, with a long career at the University of Cincinnati. His contributions were primarily in the large scale geographical understanding of American geology and based on his wide ranging studies, he produced a classification of US physiographic regions using a three-tiered system of 8 major divisions, 25 provinces and 78 sections that remains in use today.
