What are modern methods of studying the Earth for?

People began to study the Earth in antiquity, with the development of science, methods of study also developed. To discover new facts, researchers use the information that was open before them. This information is described on media that serve as sources of research.

It is necessary to know what methods of studying the Earth's plan exist. Geophysics uses magnetism, gravity, reflexive abilities, effort or acoustic waves, heat flow, electromagnetism and radio. Most of the measurements take place on the surface, but there are satellite and underground ones. It is important to understand what is located below. Sometimes it is not possible to get oil only because of the block by other material. The choice of method is based on physical properties.

Currently, the main methods of studying the Earth are the following: field, cartographic, space, statistical, geoinformation.

The field method involves the direct study of the Earth by travelers, description and mapping of the surveyed objects.

Cartographic and statistical methods belong to the so-called armchair methods, since they do not involve the use of special means and can be carried out directly by a person. These methods imply the study of the globe based on the information that the researcher already possesses - statistical or cartographic.

With the advent of satellites, the space method was developed - the study of the earth's surface using images taken from space.

Geoinformation is the latest method, based on the use of information technology, the creation of programs, global databases.
