Question

When data from the Earth's magnetic field locked inside seafloor rocks became widely understood, most skeptics around the world were convinced that seafloor spreading occurs and that the concept of plate tectonics is valid.True / False.

Answer 1

TRUE

Step-by-step explanation:

The basaltic rocks that are erupted at the seafloor are comprised of magnetic property, where the iron minerals are oriented in the north/south direction. It has been observed that the earth's magnetic polarity alters every time it erupts. This played a key role in determining that the seafloor spreading is taking place and which further provided as key evidence for the proving of the plate tectonic activity. The rocks formed at the mid-oceanic ridge are the youngest, and moving away from it, the age of the rocks increases.

Thus, the above-given statement is True.

Answer 2

True

Step-by-step explanation:

• The data form the earth's magnetic fields that are locked inside the earth's surface below and is thus an understood form seafloor spreading and plate tectonics and occurs at the concepts of the plate tectonics and is thus a valid form the viewpoints form the formation of the earth.
