What geologic discovery in the 1960's provided the scientific evidence to verify the occurrence of continental drift?

The discovery was the presence of magnetic stripes on the ocean floor which indicated that the seafloor was spreading, solidifying from melt, and the magnetic minerals contained therein were aligning themselves with the magnetic alignment of the Earth at the time of their solidification.


What three pieces of evidence did Harry Hess gather to prove that seafloor spreading was taking place?

Magnetic stripes on the seafloor showed alternating patterns of normal and reversed polarity, matching Earth's magnetic field reversals. Age dating of seafloor rocks revealed that rocks were youngest along mid-ocean ridges and oldest near continental margins. Sediment thickness on the seafloor was thinnest at mid-ocean ridges and thickest near the continents, supporting the idea of seafloor spreading.


How did research about the sea floor in the second half of the 1900s affect scientific through about continental drift?

Research about the sea floor in the second half of the 1900s, particularly the discovery of seafloor spreading and magnetic striping, provided crucial evidence to support the theory of continental drift. This research showed that new seafloor was continuously forming at mid-ocean ridges, pushing older seafloor away and supporting the movement of continents over time. This helped solidify the theory of plate tectonics, which explains how the Earth’s lithosphere is divided into plates that move and interact with each other.


How did Harry Hess discover seafloor spreading?

Harry hess' hypothesis was hot/less dense material rises up the Earth's crust toward the mid-ocean ridges. When the seafloor breaks apart, magma is forced upward and through the cracks. It cools, and becomes a new seafloor. When it moves away from the mid-ocean ridge, it becomes denser and sinks. This helps form ridges.


How did research from the Glomar Challenger help scientists support the theory of seafloor spreading?

Drill cores from the ocean floor were dated and found to be very young compared to the age of the earth. This means the crust had to be formed recently, which can be explained by creation of crust at a spreading center.

What discovery helped to prove that alfred wegner's theory of continental drift was possible?

The discovery of seafloor spreading and magnetic striping on the ocean floor in the 1960s provided compelling evidence for Alfred Wegener's theory of continental drift. This process showed how new oceanic crust is formed at mid-ocean ridges and helps move the continents apart, supporting the idea that continents are not fixed but can drift over time.

The most conclusive proof for continent drift was provided by?

The most conclusive proof for continental drift was provided by the discovery of seafloor spreading and magnetic striping on the ocean floor. This evidence showed that the Earth's continents are moving apart from each other due to the movement of tectonic plates.


What was the new evidence that was discovered that supported the theory of plate tectonics and when was it discovered?

In the 1950's a research team that was mapping the ocean floor discovered strange features around the Mid-Atlantic Ridge that indicated the ridge was seismologically active. Further mapping indicated that all of Earth's oceans had similar ridge systems, supporting the theory of plate tectonics the spreading of the sea floor


Magnetic patterns on the ocean floor were puzzling because they?

revealed a symmetrical alternation of magnetic orientations on either side of mid-ocean ridges. This suggested that new oceanic crust was being formed at these ridges, with molten magma solidifying and locking in Earth's magnetic field at the time of its creation. By studying these patterns, scientists could map the history of seafloor spreading and plate tectonics.


What was the significant about discovery of gallium?

it confirmed medeleev's prediction and showed the usedfulness of his table


Why was wegeners theory accepted in the 1960s?

Wegener's theory of continental drift gained acceptance in the 1960s primarily due to the development of plate tectonics, which provided a comprehensive framework explaining the movement of Earth's lithosphere. Advances in technology, such as sonar mapping of the ocean floor and the discovery of mid-ocean ridges, revealed evidence of seafloor spreading. Additionally, paleomagnetic studies showed that continents had shifted over geological time, supporting Wegener's ideas. This confluence of evidence from multiple scientific disciplines ultimately validated his theory.
