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.

<span>The geologic time scale is divided based on the major changes in the earth’s surface and climate, and the other thing that divides them is the extinction of species. The appearance and disappearance of fossils also help influence this division.</span>
Answer:
D. rivers, mountains, lakes, and forests.
Explanation:
A geographic information system (GIS) is a computer system that is used for analyzing various locations on Earth's surface or a geographic areas. It is used as a helping tool in planning and monitoring. Major geographic objects used for GIS are: points, lines, and polygons (areas). GIS software has various applications that are used widely in almost all fields of study.
The disadvantages are those of data transfer, of mis-match between data structures in the GIS and in the model, the difficulties for casual users and the difficulties of modifying the model code or hard-wiredparameters.
Rivers, mountains, lakes, and forests are not a member of elements for GIS analysis.
Answer:
6 continentes (modelo geológico): guarda una relación aproximada con las placas tectónicas continentales, por lo que Europa y Asia forman un solo continente denominado Eurasia y en cambio América está dividida en dos continentes (América del Norte y América del Sur).
