b)

Short-term environmental changes do not have a significant effect on the environment.

c)

Short-term environmental changes, like droughts, floods, and fires do not give populations time to adapt to the change and force them to move or become extinct. The changes happen rather quickly and there is no time for adaptations to occur which can lead to massive die-off.

d)

Short-term environmental changes, like pollution, deforestation, and ice age give populations time to adapt to the change and force them to move or become extinct.

Which of the following is the best definition for Long-term environmental changes?

a)

Long-term environmental changes tend to not affect the environment and the organisms living in it since it happens rather quickly.

b)

Long-term environmental changes do not have a significant effect on the environment.

c)

Long-term environmental changes, like droughts, floods, and fires do not give populations time to adapt to the change and force them to move or become extinct. The changes happen rather quickly and there is no time for adaptations to occur which can lead to massive die-off.
