Streak is a method used to help identify minerals. A mineral can have very similar characteristics such as luster, colour, hardness, specific gravity ect, but even minerals with very similar characteristics including colour can have different streaks...which is the 'colour' the mineral makes on a scratch plate when drawn accross it in a stroke..thus creating the streak.
To find the streak of a rock, you can rub the rock against an unglazed white porcelain tile to observe the color of the powder left behind. The color of the streak can help identify the minerals present in the rock.

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.
Another way to say streak is powder color.
