Physical geography (also known as ... Piri Reis (1465 – c. 1554), whose Piri Reis map is the oldest surviving world map to include the Americas and possibly Antarctica;
The discipline of geography, especially physical geography, and geology have significant overlap. In the past, the two have often shared academic departments at universities, a point that has led to conflict over resources. [126] Both disciplines do seek to understand the rocks on the Earth's surface and the processes that change them over time.
Physiographic Map from "Geography of Ohio," published in 1923. During the early 1900s, the study of regional-scale geomorphology was termed "physiography". Physiography later was considered to be a portmanteau of "physical" and "geography", and therefore synonymous with physical geography, and the concept became embroiled in controversy surrounding the appropriate concerns of that discipline.
(Definitions of "continents" are a physical and cultural construct dating back centuries, long before the advent or even knowledge of plate tectonics; thus, defining a "continent" falls into the realm of physical and cultural geography (i.e. geopolitics), while continental plate definitions fall under plate tectonics in the realm of geology.)

Geomorphology (from Ancient Greek γῆ (gê) 'earth' μορφή (morphḗ) 'form' and λόγος 'study') [2] 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.
If all of Earth's crustal surface were at the same elevation as a smooth sphere, the depth of the resulting world ocean would be 2.7 to 2.8 km (1.68 to 1.74 mi). [195] About 97.5% of the water is saline; the remaining 2.5% is fresh water. [196] [197] Most fresh water, about 68.7%, is present as ice in ice caps and glaciers. [198]
In his 1857 book A Treatise on Physical Geography, Francis B. Fogg commented that "the Pacific and its dependencies may be said to contain that portion of the globe termed Oceanica or 'the Maritime World', which is divided into Australasia, Malesia and Polynesia." Fogg defined Polynesia as covering the combined islands of Melanesia, Micronesia ...
