What are some possible consequences of global warming

There are so many!

Explanation:

Frequent & harsher weather- As the temperature rises, natural disasters such as storms, foods, droughts, earthquake etc will become more frequent, Along, with the increase in frequencies these disasters will become stronger. They will cause more damage than ever before seen.

Air pollution- Warmer temperature lead to an increase in pollen. Also, factories produce many dangerous gases leading to dirt air which is unsafe to breathe.

Higher sea levels- Since it is getting warmer, the arctic is melting at a very quick rate currently. The ice will melt, resulting in more water in our oceans which can pose a very serious risk to people living near the shore.

There are many other possible consequences, that's why it's important to make smart choices for our planet! :)  

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
