Time zones are separated by approximately 15 degrees longitude. Since there are 24 hours in 1 day, there are 24 time zones on Earth. As the Earth completes one full rotation of 360 degrees in 24 hours, the distance between time zones in degrees can be found by dividing 360 degrees by 24 time zones.

360/24 = 15 degrees per time zone

The correct answer is 15 degrees longitude. The Earth rotates horizontally around its axis, so time zones would be drawn from North to South. Longitudinal lines run North to South, making lines of longitude the correct choice.

The “resolution” of a map refers to the smallest thing that can be recorded on the map. For example a map of the United States might only show cities with a population of five hundred thousand or more, so a city with a population of four hundred thousand would fall outside of the resolution of the map. The ratio between map distance and actual distance is known as the “scale.”

The Peters Projection map emerged from the belief by some geographers that the Mercator Projection distorts the relative size of each continent and therefore makes some continents (Europe, North America, Asia, Antarctica) look larger than they are and makes other continents (Africa, South America) look smaller than they are. Accordingly this apparently makes people think these shrunk continents are less significant that they actually are. The Peters Projection aims to fix this mindset, particularly with regard to Africa. As it is partially based on political considerations the Peters Projection is naturally controversial.

The “international dateline” is on the opposite side of the planet to prime meridian. Whereas prime meridian is found at 0’, the international dateline is found at 180’. The international dateline is the point where each day begins for the first time, it is found in the Pacific Ocean.

The Ptolemy Projection and The Eratosthenes Projection are not actual map projections so neither of these could be correct answers. The Mercator Projection specifically emphasizes accurate direction, but in doing so distorts land size. The Peters Projection is an attempt to accurately reflect the land size of all continents equally, but in doing so it distorts distance and direction. The Robinson Projection is something of a compromise in that it attempts to minimize errors in distance, relative size, and compass direction but does not accurately depict any one of these factors wholly.

Cartography incorporates science, aesthetics, and technique to communicate spatial information effectively (usually through maps). Cartography has a long, rich history that dates back to around 700 B.C.

Formal or uniform, functional or nodal, and perceptual or vernacular are all types of regions. You will see each called by either or both names.

A thematic map is a type of map that is designed to show a theme connected with a specific geographic area. For example, a thematic map may serve to convey population growth disparities across U.S. states.

Lines of latitude, also called "parallels," measure the angular distance of points north and south of the Equator. On maps, they appear as horizontal lines across the surface of the Earth.

Nepal is a landlocked Asian country bordered only by China and India, which happen to be the two most populous nations on Earth. Nepal is bordered to the north by China, and to the south, east, and west, by India. Nepal is separated from Bangladesh by the narrow Siliguri Corridor, which is part of India.
