He was born in Gloucester, Massachussets, on January 15, 1864. He was the son of Silas Stockman Tarr, a contractor, and Abigail (Saunders) Tarr, and a descendant of Richard Tarr, first settler of Rockport, Massachussets.
After his graduation from high school in 1881, he attended the summer school of zoology at Salem and in the autumn entered Harvard as a special student at Lawrence Scientific School. His course was interrupted several times and he did not take his degree for ten years. In the meantime, however, he had done summer work under the zoologists Alpheus Hyatt and Spencer F. Baird, had spent a winter in the Smithsonian Institution, and in the employ of the United States Geological Survey had carried on intensive investigations on Cape Ann, the results of which were used by Professor Nathaniel Southgate Shaler in his monograph The Geology of Cape Ann (1890), with the wholehearted acknowledgment that "the larger part of the field observations" had been made by his assistant. Tarr had also mapped glacial moraines in Massachusetts for the Survey, and had done geological field work in New Mexico, Montana, and Texas. In 1890 he returned to Cambridge as an assistant to Shaler, and completed his work for the degree of B. S. in 1891.
In 1892 he was appointed assistant professor of geology at Cornell University. In 1906 he was made full professor and head of the department of physical geography.
He organized the Cornell Greenland Expedition which went north on Peary's ship in 1896, and in 1909 and 1911 conducted the National Geographic Society's expeditions to Alaska. He also took advantage of the opportunities which the country near Ithaca offered him to study physiographic and glacial problems and drainage, and investigated the geological history of the Finger Lake region, making surveys and a complete areal study under the auspices of the United States Geological Survey. The year before his death he was given charge of the Cornell seismographic station.
He was an associate editor of the Bulletin of the American Geographical Society from 1899 to 1911 and of the Journal of Geography from 1902 to 1912. He was the author of widely used textbooks, including The Economic Geology of the United States (1893), Elementary Physical Geography (1895), First Book of Physical Geography (1897), Elementary Geology (1897), the school geographies (1900) prepared in collaboration with Frank Morton McMurry, New Physical Geography (1904), and College Physiography (published posthumously in 1914). His professional publications include The Physical Geography of New York State (1902) and contributions to the Geological Survey dealing with the Yakutat Bay region in Alaska and the Watkins Glen region of New York. With Lawrence Martin he wrote Alaskan Glacier Studies (1914), awarded the gold medal of the Société de Géographie de Paris. Tarr also wrote scores of short scientific papers and geographical reviews and contributed a number of articles to Johnson's Encyclopedia, the International Encyclopedia, and the tenth edition of the Encyclopedia Britannica.
He died in Ithaca, survived by his wife, a son, and a daughter.
His contributions to glaciology included studies of the relation of eskers, kames, and kettle holes to the ice sheet, the significance of hanging valleys and other features of glacial erosion, the nature of ablation moraine and of the through glacier, the role of earthquakes in glacial advance, and the cause of flowage in ice. He also verified, through his researches near the living glaciers in Greenland, Alaska, Norway, Spitzbergen, and the Alps, the deductions drawn from similar phenomena in far-removed regions of former glaciation. A contemporary authority said that Tarr's studies of the dislocation giving rise to the Alaskan earthquake of 1899 were "a most important addition to our knowledge of the relation of earthquakes and faults, with accompanying changes of level of the land in relation to the sea". His work on the peneplain, on extended rivers, and on rifting in granite, was also important.

Tarr was president of the Association of American Geographers (1911 - 12), foreign correspondent of the Geological Society of London, and a member of several other professional societies. He served on the International Committee on Glaciers, and was elected corresponding member of the Royal Geographical Society of Vienna shortly before his death.
On March 28, 1892, he married Kate Story of Gloucester.
