It is impossible to determine the "absolute" ages of sedimentary rocks because none of the grains in these rocks contain radioactive elements.

true or false?

False

Explanation:

The given statement is false,the Aging of sedimentary rocks can be easily done with direct dating of the Volcanic Ash layers. Moreover,  sedimentary are layered the older layers are at the bottom and the younger layer are at the top. Although sedimentary rocks do not contain radio active element but their absolute age can be determine by direct dating of the Volcanic Ash layers.

because the two particles have an equal charge, the charges will cancel out and give the atom an overall charge of 0. so, if at atom has 35 protons in the nucleus, we could expect it to have 35 electrons orbiting that nucleus.

the climate of each region is different from one another.
