Answer:
Due to splitting of lands.
Explanation:
These Glossopteris fossils got so far apart from each other because of the splitting of super continent about 175 million years ago. Before 175 million years, India and Australia are attached to each other and these Glossopteris plants are present on these lands but with the passage of time, the lands of India and Australia split and go far away from each other so due to splitting of lands, these fossils got so far apart from each other.
