Rock salt is separated industrially through a process called solution mining or cavern mining. This involves injecting water into underground salt deposits to dissolve the salt and then pumping the saltwater solution to the surface. The solution is then evaporated to recover the rock salt.
Matching geological features across continents, such as rock formations and mountain ranges. Fossil evidence of similar species found on separate continents. Alignment of coastlines and identical climate indicators in regions that are now widely separated. Distribution of plant and animal species that suggests they were once connected. Paleoclimatic evidence, such as glacial deposits in regions that are now too warm for glaciers.
The process of matching rock layers in two different places is called correlation. Geologists study the lithology, fossils, and relative positions of rock layers to determine if they are the same age and originated from the same geological event. Correlating rock layers helps geologists understand the Earth's history and past environments.
Evidence supporting the theory of continental drift includes the matching shapes of continents like South America and Africa, similar rock formations and mountain chains across continents, matching fossils found on continents that are now separated by oceans, and the alignment of magnetic minerals in rocks on either side of mid-ocean ridges. These pieces of evidence suggest that continents were once connected and have since moved apart.

The principle of relative dating helps geologists determine the age of rocks that are separated by distance. This principle states that in an undisturbed sequence of rock layers, the youngest rocks are at the top and the oldest rocks are at the bottom. By comparing the relative positions of rock layers in different locations, geologists can infer the relative ages of the rocks.

Actually its the matching up of rocks of the same age from place to place is called correlation of the rock layers.
Correlation of rock units between continents or widely separated areas is typically accomplished using index fossils, unique mineral assemblages, or radiometric dating rather than physical features like color, texture, or thickness. These methods provide more accurate and reliable correlation techniques due to the variations that can occur in the physical characteristics of rocks over time.

Rock strata that match on different continents suggest that these continents were once connected and have since drifted apart. Fossils and geological formations found in these rock layers further support the theory of continental drift by indicating past connections between continents that are now separated. Matching rock strata across continents provide evidence of a shared history and movement of land masses over time.
An Unconformity is an erosional or non-depositional surface that separates rocks of two different ages. This is represented by missing sediments in the stratigraphic column. If the time period represented by the missing sediments is small, the unconformity is called a diastem.
Geologists have subdivided the rocks comprising Mount Everest into three units called "formations". Each formation is separated from the other by low-angle faults, called "detachments", along which they have been thrust over each other. From the summit of Mount Everest to its base these rock units are the Qomolangma Formation, the North Col Formation, and the Rongbuk Formation.
Scientists used the types of rock found on different continents, specifically matching rock formations and fossils, to support the theory of plate tectonics. By observing similarities in rock types and structures across continents separated by vast oceans, they were able to infer that the continents were once connected and moved apart over hundreds of millions of years. This helped them understand the movement of the continents and the process of continental drift.
