Climate change causes changes in weather conditions over a long period of time.
<h3>What is climate change?</h3>
Climate change refers to those long time changes in the weather condition of a place.
The heat from current climate change ultimately comes from energy from the sun, trapped by carbon dioxide in the atmosphere.
As the earth's temperature increases, the processes on earth are affected such as increased precipitation and increased sea levels.
An example of a positive feedback loop is;
- Temperatures rising cause ice and snow to melt, which causes more heat to be absorbed by the ground, causing temperatures to rise more.
- Melting ice causes more sunlight to be reflected into the atmosphere, causing the temperatures on Earth to increase, which then causes more ice to melt.
The most effective way for an individual to reduce climate change on individual basis is to turn off the lights after leaving rooms.

A: the answer would be biotic because the term biotic means that something is living or had lived before. as you can see, the table was made by fallen trees in the local forest. that means it lived before the tree was fallen and carved into a picnic table.
