A widening of a lake for example. It is a physical barrier. Not forest fires or volcanic eruptions.
Factors such as geographic isolation, environmental changes, genetic mutations, and selective pressures can increase the rate of speciation by driving populations to evolve separate traits or behaviors that lead to reproductive isolation.
A mapmaker would most likely use geographic information systems (GIS) data, satellite imagery, topographic maps, aerial photographs, and surveyed data from the field to create accurate and detailed maps.
The reason the geographic feature is a promoter to cultural diffusion is because many different geographic features had trade routes and these trade routes would help with the spread of culture. Such as when the Muslim Empire took over Spain , North Africa, and western/central Asia a lot of Arab culture became a part of them.
A geographer uses a GPS for directions. Geographers may be exploring and they need coordinates and directions for the locations they find.
Speciation is the evolution of new species from existing species and that is what has happened here. If a species was split up due to some sort of natural disaster, each party would evolve on their own because of the isolation. They will adapt to the new environment and eventually develop a new gene pool - this is when a new species has developed.
That would be geographic isolation and reproductive isolation. Both could lead to speciation.
Geographic isolation Low geneflow.
Geographic isolation from other cultural influences.
Geographic isolation is when a population is separated by a river/canyon or some impassable terrain. Habitat isolation is when members of a population live in a different type of habitat, say some live in the forest at the bottom of the mountain, while others live further up the mountain. These would then become different populations and evolve to perhaps form two different species.
These populations would be classified as different species. Geographic isolation has led to reproductive isolation, causing them to evolve independently and become unable to produce viable offspring together.
Being shipwrecked on a desert island would do it.

Geographical Isolation
The geographic isolation of the birds on separate islands. By: Yoshi
Isolation as a result of any reason that stops interchange of genes with other populations - that could be a large expanse of water, a mountain range, division of habitat with no suitable habitat between, volcanic activity, etc etc etc. . Geographic isolation takes place.
it is tundra
The different finch species in the Galapagos have evolved through geographic isolation on different islands. Each island has its own unique environment and food sources, leading to variations in beak shape and size among the finches to adapt to their specific diets. This is an example of how geographic isolation can drive speciation and the development of unique traits in isolated populations.
