Physical Features
South Africa has a very mountainous landscape, whereas Brunei has no mountains at all. That also makes a temperature change, because at such high altitudes, the temperature is often colder. There are also very large rivers in South Africa. Brunei does have a river,however, it hardly compares to the length of South Africa's Orange river. This is understandable because in Brunei there is simply not enough space to contain a river that beats the length of the ones in South Africa.
