The red particle moves in a flowing fluid; its pathline is traced in red; the tip of the trail of blue ink released from the origin follows the particle, but unlike the static pathline (which records the earlier motion of the dot), ink released after the red dot departs continues to move up with the flow. (This is a streakline.)
This glossary of geography terms is a list of definitions of terms and concepts used in geography and related fields, including Earth science, oceanography, cartography, and human geography, as well as those describing spatial dimension, topographical features, natural resources, and the collection, analysis, and visualization of geographic ...
Because = everywhere (e.g., see In terms of vector rotation), each streamline corresponds to the intersection of a particular stream surface and a particular horizontal plane. Consequently, in three dimensions, unambiguous identification of any particular streamline requires that one specify corresponding values of both the stream function and ...

Collapsed Ordovician limestone bank showing coastal erosion.NW Osmussaar, Estonia.. Coastal geography is the study of the constantly changing region between the ocean and the land, incorporating both the physical geography (i.e. coastal geomorphology, climatology and oceanography) and the human geography (sociology and history) of the coast.
A streakline starting at = (,) will intersect itself twice. See also animation below which shows the pathlines of the emitted particles (emitted every 0.5 time units) and the streaklines.

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.
Most American geography and social studies classrooms have adopted the five themes in teaching practices, [3] as they provide "an alternative to the detrimental, but unfortunately persistent, habit of teaching geography through rote memorization". [1] They are pedagogical themes that guide how geographic content should be taught in schools. [4]
