Which statements best describe half-lives of radioactive isotopes? check all that apply. the half-life varies depending on the isotope. the half-life is the same for every isotope. half-lives are always only minutes long. half-lives range from fractions of a second to billions of years. the half-life of a particular isotope is constant. the half-life of a particular isotope changes constantly.

transformative rocks are the stones that emerge from the transformation of existing rock composes in a procedure called changeability, implies changing of structures. transformative rocks are shaped from alternate shakes that are changing a result of warmth or weight connected. one of this model is the earth developments that making rocks profoundly cover or crushed which will make the stones warmed and put under awesome weight. they are not softening but rather the minerals they are containing are changed synthetically that will shape transformative rocks. now and again different rocks are shaped when the others are near some liquid magma and getting warmed.
