A circle of latitude or line of latitude on Earth is an abstract east–west small circle connecting all locations around Earth (ignoring elevation) at a given latitude coordinate line. Circles of latitude are often called parallels because they are parallel to each other; that is, planes that contain any of these circles never intersect each ...
The South Temperate Zone, between the Tropic of Capricorn at 23°26′09.9″ S and the Antarctic Circle at 66°33′50.1″ S, covers 25.99% of Earth's surface. The South Frigid Zone, from the Antarctic Circle at 66°33′50.1″ S and the South Pole at 90° S, covers 4.12% of Earth's surface. Earth's climatic zones
A geographic coordinate system (GCS) is a spherical or geodetic coordinate system for measuring and communicating positions directly on Earth as latitude and longitude. [1] It is the simplest, oldest and most widely used of the various spatial reference systems that are in use, and forms the basis for most others.
Earth's graticule. The vertical lines from pole to pole are lines of constant longitude, or meridians. The circles parallel to the equator are lines of constant latitude, or parallels. The graticule shows the latitude and longitude of points on the surface. In this example meridians are spaced at 6° intervals and parallels at 4° intervals.
The latitudinal diversity gradient has been observed to varying degrees in Earth's past, possibly due to differences in climate during various phases of Earth's history. Some studies indicate that the gradient was strong, particularly among marine taxa , while other studies of terrestrial taxa indicate it had little effect on the distribution ...
The Earth was divided into regions which he defined as tropical, temperate, and arctic and within these regions there were similar forms of vegetation. [4] This ultimately enabled him to create the isotherm, which allowed scientists to see patterns of life within different climates. [4]
Heating of solids, sunlight and shade in different altitudinal zones (Northern hemisphere) [5] A variety of environmental factors determines the boundaries of altitudinal zones found on mountains, ranging from direct effects of temperature and precipitation to indirect characteristics of the mountain itself, as well as biological interactions of the species.
The human body, to take just one life form, is made up of 60 different chemical elements. That’s despite four of them—oxygen, carbon, hydrogen, and nitrogen— representing 96.2% of the total.
