Answer:
A) Earthquakes and B) volcanic activity
Explanation:
Scientists found that the surface of our planet is always in motion. ... The knowledge of the Earth's continual motion is based on the work of scientists who study the movement of the continents. This process is called “plate tectonics.” Earthquakes and volcanic activity are a result of that process.
Both a and b are correct! But if it just wants one I would go with earthquakes first!
Hope this helps ya!
The movement of crustal rocks has been studied by various scientists and researchers. Most of them have identified earthquake activity as the major cause.
Evidence was collected from the fossils, glacial movements, and coastal patterns. Shows how the plate might have drifted or moved from their past location. Fossils are a good example of this. As the plates are always in motion they produce earthquakes and volcanic eruptions on the surface. The movement of plates can also be tracked with satellites from above.Thus the option A and B are both correct. Primarily option A
