Why do you think there are bands in the rock formation?

please follow me and mark as brainliest

Explanation:

Sometimes granite and gneiss can look very similar. One distinguishing characteristic of gneiss is its banding. Due to the pressure and heat that the granite is subjected to, similar minerals in the rock begin to align with each other, producing the bands in gneiss. This feature is known as gneissic banding.

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
