(1 Point)
World War I
World War II
Korean War
Vietnam War
The correct answer and explanation is :
The correct answer is World War II.
Explanation:
World War II indirectly played a significant role in the development of the theory of plate tectonics by advancing scientific tools and technology that made key discoveries possible. The war spurred technological innovations that would later be pivotal for geological studies, particularly the development of sonar, which allowed scientists to map the ocean floor in great detail.
During the war, sonar technology was primarily used for detecting submarines. As a result, vast underwater topographies were mapped, and significant features, such as mid-ocean ridges and deep ocean trenches, were discovered. These features were later found to be essential pieces of evidence supporting the theory of plate tectonics.
Additionally, the war stimulated advancements in computers and other scientific instrumentation, making it easier for geologists to process large amounts of data and identify patterns related to Earth’s movements. These technological advancements played a crucial role in the post-war era when scientists began to use this data to formulate ideas about continental drift and seafloor spreading, which would eventually become central components of the plate tectonics theory.
Before World War II, the prevailing view of Earth’s geological features was primarily influenced by the static Earth model, which suggested that continents had fixed positions. However, after the war, scientists like Harry Hess, who was a key figure in the development of plate tectonics theory, used the sonar data to show that the seafloor was spreading at mid-ocean ridges and that continents were indeed moving apart.
This evidence helped confirm Alfred Wegener’s earlier hypothesis of continental drift and paved the way for the comprehensive theory of plate tectonics, which explains the dynamic nature of Earth’s lithosphere.
