It isn't exactly known who discovered it first, but the earliest claim of earth being round rather than flat was posed by Pythagoras sometime around 500 B.C. He argued that if the moon was round the Earth should be as well.

After that, his claim was proven true by a man named Anaxagoras at around 500-430 B.C when he brought up solar and lunar eclipses. The shape of Earth's shadow on the moon was also used as evidence that the Earth was round.

And finally, in 350 B.C the great Aristotle declared that the Earth was a sphere based on constellations you can see if you travel farther from the equator. Over the next hundred or so years, Aristarchus and Eratosthenes actually measured the size of the earth.

What would be a likely natural feature in a densely populated area of the world?

Katen [24]

A likely natural feature in an extremely densely populated area would be a well watered, fertile plain. An example is the Northern plain of India also called the Indo - Gangetic plain. It s on one of the world's most densely populated area per square kilometer. This plain is formed from the flood plains of three great river systems - the Indus, the Ganga and the Brahmaputra. The soil cover in the plain is rich and fertile and water is found in plenty. These factors combined with a favorable climate makes it one of the most intensely farmed and populated areas in the globe.

The ocean floor preserve evidence of past magnetic reversals because c) the ocean floor is uniformly old, preserving the earth's 4.6 billion history.

<h3 /><h3>What subjects need to be studied to study the earth's magnetism?</h3>

Paleomagnetism is the study of naturally occurring residual magnetism in rocks with the goal of understanding the strength and direction of the Earth's magnetic field in the geologic past and understanding the motion history of plates. Paleomagnetic fields have played a large role in confirming undersea propagation, through the discovery and understanding of seafloor anomalies. In the 1960s, geophysicists studied the magnetic properties of the ocean floor and began to discover some amazing properties.

The seabed has a system of linear magnetic anomalies in which a "band" has all its magnetic minerals oriented in the same way as the current magnetic field and the magnetic minerals in the bands alternating is oriented in the opposite direction. These bands are oriented parallel to the mid-ocean ridge system; where the ridges compensate for the transform error, the anomalies are also compensated. Symmetrical anomalies are found on either side of the ridge, and similar symmetry is found in ridges around the world.
