Which change would be considered a short-term environmental change? check all that apply. an ice age an el niño storm a small asteroid impact a tsunami mountain building

Short term environmental change is when there are changes in the environment that affects the organisms immediately.

Explanation:

a) Ice age: It is not short term as it has effect on the climate that take place slowly with time and affect organisms over generations causing changes in DNA.

b) an EL Nino storm: It is the fluctuation in temperatures between the oceans and the atmosphere caused by changes in wind patterns. It is a short term environmental change that occurs every 5 years. Due to this there is change in wind patterns, rainfall and sea surface temperatures fluctuate. It leads to droughts causing extinction of local species and shifting of ecological communities.  

c)a small asteroid impact: It is a short term effect as it would cause damage to the ecosystem and all living beings associated with the ecosystem. Due to the impact, many species would not be alive and the climate conditions would be altered. The impact would cause extinction of species in the area affected only.  

d) tsunami: It is a short term environmental effect. Tsunami is caused by huge waves created by the movement of sea floor bed. If these waves hit the shores, then it sure to destroy human population, property, ecological habitat that would have drastic effect on other species. The flora and fauna gets destroyed which takes years for it to be replaced.

e) volcanic mountain building: It is not short term environmental effect. Volcanic mountain building are mountains that changes the weather pattern down side the mountain due to blocking of moisture flow. It also results in increased rainfall and increased water availability on the windward side of mountain.
