Question
Select the consequences associated with climate change.
- Ice sheets declining
- Oceans are becoming more acidic
- Weathers are more extremes
- All of these
Hint:
Climate change majorly occurs due to global warming and pollution
The correct answer is: All of these
Due to more global warming, heat inside Earth's atmosphere is increasing and the ice sheets are melting. Oceans are becoming acidic due to acid rain which is mostly due to unchecked pollution. And weathers have become more extreme due to global warming too.
