Which of the following is not a type of rock particle?
A: clay
B:sand
C: silt
D: Mud

Id say clay. sand, silt, and mud are formed from soil and rocks

Mud.

Explanation:

Sand clay and silt are all a rock particle  because they were all formed after years and finally formed into what we call today a rock so that leaves the mud there so mud is the answer.

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.

explanation:

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
