A rock sample that is highly effervescent is typically enriched with carbonates, such as calcite or dolomite. When these carbonate minerals react with acids, they produce carbon dioxide gas, resulting in effervescence. This characteristic is often used in geology to identify the presence of these minerals in rock samples.
streak
"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.
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?...
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
The moon rock brought back by Apollo 11 was called "Sample 10057".
"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 sample
The medium-sized rock sample had approximately 30% empty space, meaning 30% of its volume was not occupied by solid material.
density = mass/volume = 250g/45cm3 = 5.6g/cm3 (rounded to 2 sig figs)
A higher percentage of daughter isotopes present in a sample, the older the rock is.
Scoria is a highly vesicular (porous), dark colored volcanic rock.
