PLEASE HELP WILL GIVE BRAINLIEST
After letting his soil sample sit in water for an hour, Mark concludes that just one type of material made up the soil. Jack concludes that the soil had several different materials, each with a different weight. Based on the results of your experiment, whose conclusion do you support and why?

Jack is correct here.
Reason: if you think about it— it seems awfully strange if ONLY one type of material makes up the whole soil.. obviously the soil will consist of more than one. **most soil is made up of minerals, rocks and organic matter** , remember that they have several particles within them with different measurements. Hope that helped, and have a good day :-).

Yes yes yes very good

Soil? it sounds right when you r3ad it in a sentence
