This is an example of Morphological and structural adaptation
Explanation:
The morphological and structural adaptation is an anatomical adaptation, where living beings exhibit some characteristics that allow them to survive according to the environment in which they are, either promoting a camouflage, or resembling animals that are dangerous to frighten possible predators.
An example of this can be seen in the question above, where the hare, in order to survive and reproduce, allow the hair to become white as snow, and can camouflage themselves in the environment in which they are.
Physical geography focuses on natural processes of the earth, including climate and plate tectonics, whereas human geography studies the effect and behavior of humans and how they relate to the physical world. The two fields of geography are interrelated.
