Plate tectonics hope this helps :)
The correct answer is A. reeducation camps. This is because reeducation camps are camps to which people are forcibly taken while the others are practices of traditional Chinese medicine.
it can help animals i hope this helps
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.

Answer: Yes and No
Explanation: If you mean to form a rock from scratch, then there's only pressure, heat and sedimentation involved. If you mean take shape from a piece of solid magma to a 'rock', then yes, it helps shape it and round it to be joined with the environment.
