Sand has no nutrients and vitamin C but soil does.

My answer is dirt I'd say dirt because the dirt is more flat than the dirt.Also,the grass has the leaves poped out so the ball will be faster on dirt......
a Levee construction HYPOTHESIS ----------------- levees constructed out of rock will probably hold the most force because rock is strong. VARIBLES ------------ the variables are levees made of the following materials LEVEE 1) dirt LEVEE 2) dirt and sand mix LEVEE 3) dirt , sand , and rock mix LEVEE 4) dirt and rock mix mixtures are made of equal All levees are equal size and sha
well, it is obvious that carpet would most likely win. the reason why is because it is the hardest surface. and it does not depent on the details. it depends, though, on the weight of the ball. if it is lighter, the ball would be faster and easier to use.
Oh, dude, the controlled variable in that experiment would be the type of ball used. You gotta keep that constant so you can accurately compare how far it rolls on grass versus dirt. Like, you wouldn't want to use a bouncy ball on one surface and a heavy bowling ball on the other, that would just be a mess.
i think that the sewers are making the thames dirty
dirt. dirt. dirt......... and dirt

The dirt under grass can be called soil.
Grass of course! Grass is more solid than dirt.
To make a good science project you must change something in it, like were would the banana rot best and why?or why did the plant grow best in the dirt rather then in the sand? it'll help trust me. answered by Vallerie (to l's) Heredia
a ball can go further than grass and dirt
Grass
Neither. The ball rolls faster on cement, not grass, or dirt.
The reason a ball rolls farther on dirt is because the grass has more potenial than dirt because once you roll the ball really hard the ball will slow down on grass and the grass is sometimes standing up and the dirt doesn't have any thing to stop the ball the dirt is is flat unlike the grass.
