Question

question 9(multiple choice worth 6 points) (03.04 mc) which of the following provides evidence to support vine-matthews-morleys first scientific test of the theory of seafloor spreading? fossils of the same plants and animals found in different seas sonar shows details of an underwater divergent boundary continents look like puzzle pieces that can be fit into one another symmetrical pattern of magnetic stripes in the crust on both sides of the mid - ocean ridge

Explanation:

Vine - Matthews - Morley's theory of seafloor spreading was supported by the discovery of symmetrical magnetic stripes in the ocean crust on either side of the mid - ocean ridge. As new oceanic crust is formed at the mid - ocean ridge (a divergent boundary), it records the Earth's magnetic field at the time of its formation. Over time, as the Earth's magnetic field reverses, these reversals are recorded in the newly formed crust. The symmetrical pattern of these magnetic stripes on both sides of the mid - ocean ridge shows that the seafloor is spreading away from the ridge.

Fossils of the same plants and animals in different seas is evidence for continental drift (not specifically for Vine - Matthews - Morley's test of seafloor spreading). Sonar showing details of an underwater divergent boundary is a general observation about plate tectonics (mid - ocean ridges are divergent boundaries) but not the specific evidence for Vine - Matthews - Morley. Continents looking like puzzle pieces is also evidence for continental drift.

Answer:

Symmetrical pattern of magnetic stripes in the crust on both sides of the mid - ocean ridge.
