Also amphidrome and tidal node. A geographical location where there is little or no tide, i.e. where the tidal amplitude is zero or nearly zero because the height of sea level does not change appreciably over time (meaning there is no high tide or low tide), and around which a tidal crest circulates once per tidal period (approximately every 12 hours). Tidal amplitude increases, though not ...
[1] [2] 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 ...

A terrace consists of a flat or gently sloping geomorphic surface, called a tread, that is typically bounded on one side by a steeper ascending slope, which is called a "riser" or "scarp".

Original mapping by John Snow showing the clusters of cholera cases in the London epidemic of 1854, which is a classical case of using human geography. Human geography or anthropogeography is the branch of geography which studies spatial relationships between human communities, cultures, economies, and their interactions with the environment, examples of which include urban sprawl and urban ...
Human geography – one of the two main subfields of geography is the study of human use and understanding of the world and the processes that have affected it. Human geography broadly differs from physical geography in that it focuses on the built environment and how space is created, viewed, and managed by humans, as well as the influence humans have on the space they occupy.
We define P 1 as the player moving first and P 2 as the player moving second and name the nodes N 1 to N n. In the above figure, P 1 has a winning strategy as follows: N 1 points only to nodes N 2 and N 3. Thus P 1 's first move must be one of these two choices. P 1 chooses N 2 (if P 1 chooses N 3, then P 2 will choose N 9 as that is the only ...
[11] The geography of Ireland comprises relatively low-lying mountains surrounding a central plain, with several navigable rivers extending inland. Its lush vegetation is a product of its mild but changeable climate which is free of extremes in temperature.
