. the geographic meridian that lies 180° both east and west of the prime meridian, forming the great circle that divides the earth into the Eastern Hemisphere and the Western Hemisphere and serves as the meridian on which the International Date Line is based.
The distance around the Earth measures 360 degrees. The meridian that runs through Greenwich, England, is internationally accepted as the line of 0 degrees longitude, or prime meridian. The antimeridian is halfway around the world, at 180 degrees. It is the basis for the International Date Line
An antimeridian is the meridian of longitude opposite any given meridian. A meridian and its antimeridian form a continuous ring around the Earth. The Antimeridian is the meridian of longitude opposite the Prime Meridian.
Roughly, if the sun is on that line, it’s noon, standard time. Now, “ante” (pronounced an-tee) means “before” and “post” means “after.” So if it’s morning, the sun is before the meridian, or “ante meridiem.” That’s why morning is a.m. Past noon, the sun is after the meridian, or “post meridiem.” That’s p.m
occurring before noon : of or relating to the forenoon antemeridian chores at 9 o’clock — compare ante meridiem.
The prime meridian is the line of 0° longitude, the starting point for measuring distance both east and west around the Earth. The prime meridian is arbitrary, meaning it could be chosen to be anywhere.
The plants in frigid zone are- mosses, lichens, grasses, flower bearing plants and berry bearing shrubs.
The frigid zone is the coldest area on the earth’s surface and is covered all year round with snow. The temperature varies from 3 degrees to 12 degrees in the summer.

The Earth has three main climate zones: tropical, temperate, and polar. The climate region near the equator with warm air masses is known as tropical. In the tropical zone, the average temperature in the coldest month is 18 °C.
