Geography

Setler [38]3 years ago
8 0

Answer:

<u>Bands of magnetism are found on the earth sea floor by the process of seafloor spreading.</u>

Explanation:

  • As the rising magma from the deep vent of the mid-oceanic ridges. The deposition of magma or lava at the floors of the oceanic beds after solidification leads to the dual magnetic properties that are aligned by the magnetosphere of the earth.
  • This magnetism has several properties and the hard and soft bands of rocks are created as a result of the spreading of lava on both sides of the ridges having reverse magnetic properties.
  • Seafloor spreading and divergence is responsible for the opening up of sea bottoms and hence positively and negatively charges ions are released through this process in lava. Hence the hard and old est rocks are found away from the ridges and soft and smooth rock near the ridges.
  • Studied in Paleomagnetism evidence provided by Harry Hess.

What are the positive and negative effects of geological structures in our environment?
Marrrta [24]
The negative effects of geological structures in our environment can be landslides occurring on unfavorably oriented geological structures causing damage and sometimes loss of life on highways and railways, for example.A positive effect of geological structures is that where there are subduction zones, mineral deposits can form above them on the adjoining continents like in British Columbia on the west coast of North America. Also, faults and fractures can allow hydrothermal fluids charged with metals to form ore deposits.
