Alfred Wegener used several pieces of evidence to support his idea of moving continents. These included the jigsaw-like fit of the continents, similar fossil species found on different continents, matching geological formations across different continents, and the presence of coal in Antarctica, which suggested it once had a warmer climate.

The primary technical weakness with Wegener’s continental drift theory was that he could not provide a satisfactory explanation for the mechanism that drove the continents to move.

(a) Contractionists believed that mountains were formed as the Earth cooled and contracted, causing the crust to wrinkle and form mountain ranges. (b) Permanentists, on the other hand, believed that mountains were formed by vertical forces and that the Earth's features had remained largely unchanged.

In the late 19th century, the trans-Atlantic paleontological matchups were explained by land bridges that were thought to have once connected the continents.

In the context of isostasy, the buoyancy of the continental crust, which is less dense than the oceanic crust, would prevent an area of continental crust from becoming part of an ocean.

In the early part of the 20th century, we learned about the topography of the sea floor through echo sounding, a technique that uses sound waves to measure water depth.

The temperature profile of the crust and the mantle indicates that part of the mantle must be convecting because heat increases with depth, suggesting that hot material is rising from the deep mantle towards the crust.

Paleomagnetic studies provided support for continental drift by showing that the Earth's magnetic field has reversed many times in the past, and these reversals are recorded in the rocks of different continents, indicating they were once joined.

The deepest parts of the oceans are the ocean trenches, such as the Mariana Trench in the Pacific Ocean.

There is less sediment in the ocean ridge areas than in other parts of the sea floor because new oceanic crust is constantly being formed at these ridges, pushing older sediment-covered crust away.

The oceanic heat-flow data is related to mantle convection in that the highest heat flow is observed at the mid-ocean ridges where new crust is being formed, indicating upwelling of hot mantle material.

Earthquakes at ocean ridges are shallow and occur along the ridge axis, while earthquakes at ocean trenches can be very deep and are associated with subduction zones where one tectonic plate is forced under another.

In Harold Hess's model for ocean basins, new oceanic crust is formed at oceanic ridges through seafloor spreading, and old oceanic crust is destroyed at oceanic trenches through subduction.

The aspect of plate tectonics not included in the Hess theory is the mechanism driving the movement of the plates.

As a text-based AI, I'm unable to draw images. However, in the context of sea-floor magnetic anomalies, the spreading ridge would likely be located where there is a symmetrical pattern of anomalies on either side.
