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? Group of answer choices 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 seasonal change, not a long-term change.

Explanation:

The fault in Gwen's thinking is that an asteroid impact is a seasonal change and not a long-term change.

An asteroid impact involves the collision of astronomical objects and it is an event that only happens seasonally and within a short period.  Hence, an asteroid impact can only cause short-term changes, and whatever effects they create can only last for a while.

A short-term event like an asteroid impact is not comparable to a long-term event like global warming, for example. Long-term events take time to produce effects and these effects can last for years, unlike short-term events.
