Hemispheres

Each half of the earth is called a hemisphere. These are divisions of Earth's sphere that follow longitudinal and latitudinal lines to divide the earth into two parts. Earth can either be divided into to northern and southern hemispheres or eastern and western hemispheres.

Depends on the context.

If it's on the Earth, the imaginary line running east-west at 0 degrees is the equator.

In geometry, such a thing would not be a line, but a ray, and it would only run in one direction.

You can imagine an enormous knife, cutting the Earth into two pieces. Whenever the center of the Earth is on the cut, the pieces are equal, and they're both hemispheres.

If you cut through the equator, then you have the northern and southern hemispheres.

If you cut through the Prime Meridian, then you have the eastern and western ones..

If you cut any other way, then you have a couple of hemispheres that are not of much use to anyone, since they have no relationship to the Earth's rotation, and those don't have names.

The Equator divides the Earth into two equal halves, the Northern Hemisphere and the Southern Hemisphere.

North America and Europe are totally above the Equator

Elevation maps are used to show that the Himalaya mountains are the highest in the world. These maps visualize the varying heights of land surfaces, with the Himalayas standing out prominently due to their towering peaks, including Mount Everest, the highest point on Earth.

In the Eastern Hemisphere, major oceans include the Indian Ocean, the Pacific Ocean (which stretches across the International Date Line), and parts of the Southern Ocean and the Arctic Ocean. These oceans contribute to global ocean currents, weather patterns, and marine biodiversity in the Eastern Hemisphere.

In Thailand, young men can become monks at any age, with some choosing to do so temporarily as a rite of passage or to gain merit. Traditionally, the period of monastic ordination can range from a few weeks to several months, but it ultimately depends on personal choice and family circumstances.

Because 15 degrees of longitude is equivalent to 1 hour in time (that is 360 / 24) it is convenient to adopt time zones at 7.5 degrees or 15 degrees multiples.

In other words time zones are separated by multiples of 1 hour or 1/2 hour.

That point is in the polar pack ice that surrounds the north pole.

It's roughly 345 miles from the pole, and about 135 miles northeast of the nearest point of land

on the north coast of Greenland.

Cyclones can cause many disasters to humans such as mosquito borne illnesses and floods. Floods by cyclones, which cause stagnant water, can lead to diseases and overall dirty are and environment. A lot of the standing water has feces and dead animals.

The unit of length that most nearly matches the width of your finger is the inch.

Most of northern Africa is characterized by arid or semi-arid land, with vast deserts like the Sahara covering a significant portion of the region. The climate is generally dry and hot, with limited vegetation and water resources in many areas.

There are temperate and tropical grasslands.

Tropical grasslands are found in places like the savanah, temperate grasslands are found in places like the great plains in North America.

The Pantheon in Rome is a circular building with a diameter of 43.3 meters (142 ft) and a height to the oculus of also 43.3 meters (142 ft). It is considered one of the best-preserved ancient Roman buildings.

The equator separates the world into the northern hemispher and the southern hemisphere.

Greenland belongs to the Northern Hemisphere, while New Guinea is located in the Southern Hemisphere.

That's a very long timetable from 4,500, 000,000 years ago right up to 542,000,000 years ago, a total of 3,958,000,000 years.

From low surface temperatures, with extensive glaciation to warm temperate conditions and no glaciation, which seemed to have occured in cycles over that time period.

latitude 51° 31′ 18.12″ N, longitude 0° 43′ 3.72″ W

Hemi is a prefix for a half or splitting something into two equal parts. Therefore a hemisphere is half of a sphere.

There are two hemispheres, which two depends on where you make the split. Horizontally at the equator would give you north and south, vertically at the prime meridian would give you east and west.

Vietnam is located in the eastern hemisphere. It straddles the equator, so it is also in the northern hemisphere.
