Modern corals are restricted to growing in warm, clear, well-lit, shallow water. Over the last two million years, coral reefs have undergone periods of great growth as well as mass extinctions. All BUT one catastrophic event has contributed to the changes in reefs over the years. That is
A) meteor impacts.
B) global ice ages.
C) destruction of the rainforest. **?
D) the rise and fall of sea level.
Please check my answer.
so whats the answer then
i agree with ms sue
where they put the "***"
Your answer of C) destruction of the rainforest is incorrect. The catastrophic event that has NOT contributed to the changes in coral reefs over the years is A) meteor impacts.
To arrive at this answer, let's analyze the options:
A) Meteor impacts: While meteor impacts can certainly cause widespread destruction and extinctions, they have not been identified as a significant factor in the changes of coral reefs over the last two million years. So, this option is the correct answer.
B) Global ice ages: Ice ages can have a significant impact on the climate and sea levels, which can in turn affect coral reef growth and distribution. Therefore, it is a probable cause for the changes in reefs.
C) Destruction of the rainforest: The destruction of rainforests, while a major environmental concern, is not directly linked to the changes in coral reefs. So, this option is not the correct answer.
D) The rise and fall of sea level: The rise and fall of sea level is a crucial factor that influences the growth and distribution of coral reefs. As sea levels change, it can lead to either the submersion or exposure of coral reefs, affecting their survival.
In conclusion, option A) meteor impacts is the catastrophic event that has not contributed to the changes in coral reefs over the years.
