Answer:
The presence of bituminous coal in Antarctica suggests that the continent had a significantly warmer climate in the past, supporting lush vegetation and swampy environments.
Step-by-step explanation:
The existence of bituminous coal implies that Antarctica was once covered by abundant vegetation, indicating a much warmer climate compared to its current icy conditions. This historical evidence suggests that the continent had experienced a period of more temperate or even tropical climate conditions, supporting the growth of lush plant life and the formation of swampy environments that eventually led to the creation of coal deposits.
