How do living things impact the environment in negative ways and positive ways? Give an example of a negative impact and a positive impact of one living thing. I will take an answer at any time. It can be a few hours or a day or so after I asked.

answer: 21

step-by-step explanation:

divide 630 by 30. 30 goes into 630 21 times

rising temperatures because when water vapor in the air is cooled, it condenses. it turns back into a liquid and attaches to dust particles in the air. these very small water droplets group together to form clouds

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.  

hope this

c is the correct answer!
