Evaluate the idea that cross-cultural differences arise from geography.

A good answer would include the following key points:
-Some theorists have proposed that cross-cultural differences arise from geographical constraints such as terrain, climate, or other environmental characteristics.
-This approach makes sense, as a variety of examples will attest.
-A culture that develops within a gloomy, snowbound setting is likely to foster collectivism, as inhabitants realize the benefits of cooperating with one another to combat the harsh conditions of their climate.
-Similarly, a culture that develops along a major seaport or river is likely to foster traits of extraversion, agreeableness, or conscientiousness, as inhabitants recognize the value of working well with others to the mutual benefit of all.
-Rich farmland should promote cooperative motives, just as bleak deserts are likely to inspire an individualistic, nomadic lifestyle.
-In short, many geographic differences could contribute to cross-cultural differences in personality, experience, or motives.
