Long and Short Term Changes

A type of environmental change where changes occur quickly and do not give time for organisms to develop adaptations, which can sometimes lead to die-offs or extinctions.

• Long-term

• Short-term

A type of environmental change that can cause changes in the ecosystem which will affect organisms in that environment over several generations.

• Long-term

• Short-term

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

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

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

• 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.

• Long-term environmental changes, like pollution, deforestation, and ice age are much more gradual and allow populations to adapt. Overtime, organisms that are affected by these changes have a chance to survive as they can develop adaptations that will help them cope with the change.
