Who studied geological changes that shaped the earth?

Answer 1

Short Answer:

The ancient Greeks discovered the shape of the Earth was round (sphere) 25 centuries ago.

In 1687, Isaac newton said the Earth was an oblate spheroid (slightly bulged at the equator) due to the centrifugal force from the Earth's rotation..

Long Answer:

More than 2400 years ago, the ancient Greeks knew the Earth was round, knew its size and knew it orbited the Sun.

Aristarchus (310 BC -- 230 BC) of Samos is the first on record to have claimed the Earth went around the Sun, a claim which necessitates both the Earth and Sun being round.

In the same era (240 BC) Eratosthenes of Alexandria calculated the Earth's circumference (hence radius) to an accuracy of a few percent, using the change in the angle of elevation of the noon Sun between Alexandria and a location that is now Aswan, Egypt.

In 1687, Isaac Newton said the shape of Earth should be an oblate ellipsoid (also called oblate spheroid) instead of a sphere and that was confirmed by measurements of French mathematician and physicist Pierre Louis Maupertuis in 1736.

Answer 2

Geologists study the geological changes that have shaped the Earth. These scientists analyze rocks, minerals, and fossils to understand the Earth's history and how it has evolved over time. By studying processes like plate tectonics, erosion, and volcanic activity, geologists can piece together the story of our planet's past.

Christopher Columbus proved it, by sailing right round the world. His friends were worried because they thought that he would drop off of the edge of the earth, but he thought that he wouldn,t.

Answer 4

The study of Earth's landforms is known as geomorphology and is studied by geomorphologists.

Geology is the study of the Earth, the materials of which it is made, the structure of those materials, and the processes acting upon them. It includes the study of organisms that have inhabited our planet. An important part of geology is the study of how Earth's materials, structures, processes and organisms have changed over time.

Answer 5

Scientists have always known the Earth is round. They have not always know the exactly distance. It was not possible to measure it exactly until the first artificial satellites were launched. At that point it was discovered the earth was slightly pear shaped. The biggest surprise was the holes in the ocean. Scientists expected the oceans to be flat. They are not.
