Ah, great mountain barriers are like nature's gentle giants, standing tall and strong to protect and guide us. They create a sense of awe and wonder, reminding us of the beauty and power of the world around us. Just like how we can overcome obstacles with patience and determination, these mountains teach us that challenges can lead to growth and new perspectives.

How do Fitch barriers help protect drivers?

When the force exerted on a car hitting a barrier is proportional to the acceleration of the car the driver in the car will fly through out the car. So the Fitch barriers protect the driver so when the driver drives over these Fitch Barriers the Fitch Barriers slows down the car to pervent there to be a collision.


What are three events that can lead to speciation?

Species (phylogenetically and genetically distinct animals from a common ancestor) form when barriers exist to prevent outbreeding. These are usually environmental (e.g. mountain ranges, oceans, climatic barriers) or biological (e.g. interbreeding of two species results in an infertile offspring).


What is a non example of geographical isolation?

The great lakes is an example of a geographic barrier, isolating populations from each other. Populations can become separated (isolated) from one another, as one group expands northward of the lakes and another expands southward of the lakes. Mountain ranges are geographic barriers that isolate populations from one another, in much the same way as the great lakes. Oceans geographically isolate land masses, and their respective populations, from one another. This includes islands as well as continents. Examples: the Galapagos Islands, Madagascar, and Australia. *Geographic isolation is the chief mechanism of allopatric speciation, considered by some to be a theory.
