Question

Gwen is researching the effects of a small asteroid impact in an area that has started to regrow after being hit ten years ago. She considers the event to be a long-term change because the species of plants that were present had to start completely over from seeds after all of the plants in the area were killed by the impact.
What is the error in Gwen’s thinking?
Species will not regrow after an asteroid impact.
An asteroid impact is not an environmental change.
This is a seasonal change, not a long-term change.
This is a short-term change, not a long-term change.

Answer 1

Answer:

An asteroid impact is not an environmental change. This is a short-term change, not a long-term change.
