Geography (from Ancient Greek γεωγραφία geōgraphía; combining gê 'Earth' and gráphō 'write') is the study of the lands, features, inhabitants, and phenomena of Earth. [1] 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 ...
A basin is separated from adjacent basins by a perimeter, the drainage divide, [1] made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. [2]
Coastal geography is the study of the dynamic interface between the ocean and the land, incorporating both the physical geography (i.e. coastal geomorphology, geology, and oceanography) and the human geography of the coast.
The internal structure of Earth. In geology, the crust is the outermost solid shell of a planet, dwarf planet, or natural satellite.It is usually distinguished from the underlying mantle by its chemical makeup; however, in the case of icy satellites, it may be defined based on its phase (solid crust vs. liquid mantle).
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.
The Earth's mantle is a layer of silicate rock between the crust and the outer core.Its mass of 4.01 × 10 24 kg is 67% the mass of the Earth. [1] It has a thickness of 2,900 kilometres (1,800 mi) [1] making up about 84% of Earth's volume.
A mountain system or mountain belt is a group of mountain ranges with similarity in form, structure, and alignment that have arisen from the same cause, usually an orogeny. [1] Mountain ranges are formed by a variety of geological processes, but most of the significant ones on Earth are the result of plate tectonics . [ 2 ]
The series was re-released in 2003 on DVD as Acland's DVD Atlas of Human Anatomy. The series uses unembalmed human specimens to illustrate anatomical structures. [3] Intended for use by medical, dental and medical science students, the video teaching aid uses simple language and high quality images.
