Which statements describe color and streak? check all that apply. - streak is the color of a minerals powder. - most minerals occur in more than one color - color is more accurate than streak in identifying minerals - steak is tested by scraping a mineral across a streak plate - the color of the streak is the same as the color of the mineral

A mineral is an inorganic substance that is extracted from the ore after the mining process. The mineral can be identified on the basis of physical properties like color, luster, appearance, texture and by the chemical composition.

The streak is the method of mineral identification in which the mineral is scrapped off across a streak plate to determine the exact color of the mineral by the color of the powder as two or more minerals may look alike on the basis of color. This method will allow to determine the exact color of the mineral.

On the basis of the above description, these are correct statements:

- streak is the color of a minerals powder.

- most minerals occur in more than one color.

- steak is tested by scraping a mineral across a streak plate.

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.

the answer is: metamorphic rocks often show the presence of fossils, also a
