The answer is the ocean-continental convergence. This is where the gold of the Inca civilization come from.
Answer:
D)
Explanation:
Legend is over the map, thus, making the map harder to read.
Answer:
go get a answer by yourself and don''t search up by your teacher
Explanation:
Answer:
Subduction happens in Location A but not in Location B.
Explanation:
In the two descriptions, we have two different types of plate boundaries. At location A, where the plates collide, and one moves over the other while the other is pushed downward, we have a convergent plate boundary. At location B, where the plates slide past each other, we have a transform plate boundary.
- At location A, a subduction zone will occur. The subduction zone will appear at the point where the two plates collide, and if it is in the ocean, there will be a trench, if it is on land, a mountain chain will be forming.
- At location B, there will not be a subduction zone, instead, there will be a fault. A fault will occur because of the sliding past each other of the plates, as they create big pressure between each other, so at the boundary itself, there will be cracks in the crust where the crust is under immense pressure and it often results in earthquakes.
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.
