streak
Drop it in water. Fill a graduated cyllinder with water to cover the sample and record the volume. Then gently lower the rock sample into the water and record how much the water rose. The difference is the volume of the rock. Drop it in water. Fill a graduated cyllinder with water to cover the sample and record the volume. Then gently lower the rock sample into the water and record how much the water rose. The difference is the volume of the rock.
what is the formual for Density? (mass of object diveded by its volume) What is the desity of Rock sample A? (690 g / 333 cm3 = 2 g/cm3) What is the desity of Rock sample B? (506 g / 506 cm3 = 1 g/cm3) Therefore...Rock sample A is denser than Rock sample B !! Or is it?...
"centi" is 100. 1 centigram is 100 grams, so Denise's sample is 68,400 centigrams. 68400 - 29510 = 38890 centigrams or 388.90 grams.
A higher percentage of daughter isotopes present in a sample, the older the rock is.
streak
The color of a powdered sample of a rock is called its streak. Streak is determined by rubbing the sample across a rough white ceramic plate to reveal the color of the mineral's powder.
A core sample of a mineral
its structure

a sample
geologists can study a rock sample by observing its composition, color, and texture. they also look at the rocks structure, hardness and weight.
Actually, the rock taken the farthest away from the ridge is older.
density = mass/volume = 250g/45cm3 = 5.6g/cm3 (rounded to 2 sig figs)
