Answer:
Climate change is the change of temperature in the worlds climate system and climate variability is the variations in a certain climate that last longer then certain weather events.
Explanation:
To explain more climate change is the change in the daily weather in a area for example rain forest to desert or cold to hot climate change goes along with global warming which is the heating of our Earth which causes ice to melt in the arctic rising our sea levels creating stronger storms. While in a climate variability its only a certain time of that specific climate change for example its only cold for a certain period of time then the temperature rises to hot again. So, the key difference is that "climate change is the change of temperature in the worlds climate system and climate variability is the variations in a certain climate that last longer then certain weather events."
Hope this helps!
<span>Carbon is the only element that can form many different compounds. Each carbon atom can form four chemical bonds to other atoms. This allows it to form rings and chains.</span>
Answer:
A chemical reaction is the process in which atoms present in the starting substances rearrange to give new chemical combinations present in the substances formed by the reaction. These starting substances of a chemical reaction are called the reactants, and the new substances that result are called the products.
