ABC-CLIO, LLC is a publishing company for academic reference works and periodicals primarily on topics such as history and social sciences for educational and public library settings.
Africa is the world's second largest and second most-populous continent (behind Asia in both categories).
The Amazon River (or; Spanish and Amazonas) in South America is the largest river by discharge volume of water in the world, and either the longest or second longest.
The Arctic Circle is the most northerly of the five major circles of latitude as shown on maps of Earth.
Asia is Earth's largest and most populous continent, located primarily in the Eastern and Northern Hemispheres.
The Atlantic Ocean is the second largest of the world's oceans with a total area of about.
In astronomy, axial tilt, also known as obliquity, is the angle between an object's rotational axis and its orbital axis, or, equivalently, the angle between its equatorial plane and orbital plane.
Generally speaking, a calendar year begins on the New Year's Day of the given calendar system and ends on the day before the following New Year's Day, and thus consists of a whole number of days.
The Caribbean is a region that consists of the Caribbean Sea, its islands (some surrounded by the Caribbean Sea and some bordering both the Caribbean Sea and the North Atlantic Ocean) and the surrounding coasts.
Central America (América Central, Centroamérica) is the southernmost, isthmian portion of the North American continent, which connects with the South American continent on the southeast.
Two-dimensional rotation can occur in two possible directions.
In physics, the Coriolis force is an inertial force that acts on objects that are in motion relative to a rotating reference frame.
The dry season is a yearly period of low rainfall, especially in the tropics.
Earth is the third planet from the Sun and the only astronomical object known to harbor life.
An equator of a rotating spheroid (such as a planet) is its zeroth circle of latitude (parallel).
An equinox is commonly regarded as the moment the plane (extended indefinitely in all directions) of Earth's equator passes through the center of the Sun, which occurs twice each year, around 20 March and 22-23 September.
Europe is a continent located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere.
In science and engineering the study of high pressure examines its effects on materials and the design and construction of devices, such as a diamond anvil cell, which can create high pressure.
The Horn of Africa is a peninsula in East Africa that juts into the Guardafui Channel, lying along the southern side of the Gulf of Aden and the southwest Red Sea.
The invariable plane of a planetary system, also called Laplace's invariable plane, is the plane passing through its barycenter (center of mass) perpendicular to its angular momentum vector.
The March equinox or Northward equinox is the equinox on the Earth when the subsolar point appears to leave the southern hemisphere and cross the celestial equator, heading northward as seen from Earth.
Maritime Southeast Asia is the maritime region of Southeast Asia as opposed to mainland Southeast Asia and comprises what is now Malaysia, Brunei, Philippines, Singapore, Indonesia, and Timor Leste.
The Milky Way is the galaxy that contains our Solar System.
The Moon is an astronomical body that orbits planet Earth and is Earth's only permanent natural satellite.
North is one of the four compass points or cardinal directions.
North America is a continent entirely within the Northern Hemisphere and almost all within the Western Hemisphere; it is also considered by some to be a northern subcontinent of the Americas.
The North Pole, also known as the Geographic North Pole or Terrestrial North Pole, is (subject to the caveats explained below) defined as the point in the Northern Hemisphere where the Earth's axis of rotation meets its surface.
The North–South divide is broadly considered a socio-economic and political divide.
In oceanography, a gyre is any large system of circulating ocean currents, particularly those involved with large wind movements.
The Pacific Ocean is the largest and deepest of Earth's oceanic divisions.
The Solar SystemCapitalization of the name varies.
A solstice is an event occurring when the Sun appears to reach its most northerly or southerly excursion relative to the celestial equator on the celestial sphere.
South America is a continent in the Western Hemisphere, mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere.
The South Pole, also known as the Geographic South Pole or Terrestrial South Pole, is one of the two points where the Earth's axis of rotation intersects its surface.
The Southern Hemisphere is the half of Earth that is south of the Equator.
Summer is the hottest of the four temperate seasons, falling after spring and before autumn.
In geography, the temperate or tepid climates of Earth occur in the middle latitudes, which span between the tropics and the polar regions of Earth.
The Tropic of Cancer, also referred to as the Northern Tropic, is the most northerly circle of latitude on Earth at which the Sun can be directly overhead.
A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain.
The tropics are a region of the Earth surrounding the Equator.
The monsoon season, is the time of year when most of a region's average annual rainfall occurs.
Winter is the coldest season of the year in polar and temperate zones (winter does not occur in the tropical zone).
