Which of these is an environmental change that occurs rapidly?

a. forest succession

b. tree growth

c. decomposition

d. volcanic eruption

for i will give brainliest for first answer

D. Volcanic Eruption

Explanation:

Okay, logically, if you look at the answer I've given (Volcanic Eruption) there's a clear idea that this doesn't just take time to happen.  No, Volcanic Eruptions happen within a few hours, and end up with big drastic changes within that time span, which is much shorter than the other options time span of change (Tree Growth, Decomposition, Forest Succession).

I also did the test.

i believe the answer is a or 1
