The theories of continental drift and plate tectonics. These are relatively new ideas; when I was young, they were still fairly controversial. But as the evidence has accumulated, most people have become convinced that these are valid explanations of how things came to be as they are.
Just remember that the next time somebody says that something is "settled science"; the science of any discipline is NEVER settled.
The scientists that found the fossils found that were found on different continents. Some of the same fossil were located on each Continent that could only survive in one climate. Therefore, a fossil provided some evidence for the continental drift to be true.
* Magmatism creates new crust along continental margins and as island arcs such as with the subduction of the Juan de Fuca plate under the North American plate continues to add material to the crust in the Cascade Range. * Accretion of pieces of crust such as island arcs and sea mounts with existing large continents. As plate movements subduct plates, the subducted plates bring with it land masses that if sufficiently buoyant can collide and merge with the larger continent.

Hypothesis 1: When you disturb the skin of an apple by cutting the apple into half, the exposed area will turn brown due to exposure to air.Hypothesis 2: If you snugly wrap or cover the exposed area of an apple after cutting it (disturbing the skin), you can slow down how fast the inside turns brown. Hypothesis 3: If you remove all of the skin of an apple and let it sit in the air, the outside will turn brown but the inside will not turn brown at the same rate. Hypothesis 4: If you remove all the skin of an apple AND slice the whole apple into pieces, all sides exposed to air will turn brown; if some slices are thicker, the inside will turn brown more slowly than the exposed outside areas.
The temperature of the wire will increase and eventually like the "straw breaking the camel's back" the wire will fail if you apply enough current. It is like exceeding the current in a fuse, the wire essentially disintegrates.
its Continental drift
The hypothesis that the continents have mved slowly to their current locations.
The hypothesis that continents have slowly moved to their current locations is called continental drift. This theory was proposed by Alfred Wegener in the early 20th century and later developed into the theory of plate tectonics, which explains how the Earth's lithosphere is divided into large plates that move and interact with each other. This movement of continents is driven by processes like seafloor spreading and subduction at plate boundaries.
Plate tectonics.
The theory that continents have moved slowly over time to their current locations is called continental drift. This theory was proposed by Alfred Wegener in the early 20th century and later developed into the theory of plate tectonics, which explains the movement of Earth's lithosphere through the interaction of tectonic plates.
The theory proposing that continents slowly moved into their current locations is called "plate tectonics." This theory suggests that Earth's outer shell is divided into several plates that glide over the mantle, causing the continents to shift over time.

Continental drift.
The hypothesis is called continental drift. It suggests that the Earth's continents were once part of a single supercontinent called Pangaea and have since moved slowly over time to their current positions. This movement is driven by the process of plate tectonics.
