Which tool would a geologist use to find the color of a mineral in its powdered form? a. acid b. hardness points c. magnet d. streak plate

D. streak plate

Explanation:

A geologist use a streak plate to find the color of a mineral in its powdererd form.

To determine the color of a mineral, the geologist uses a technique called color of the stripe or footprint.

This technique involves taking the mineral and spreading a part of it on a plate to determine its color.

This is a mineral identification technique since its composition can be determined according to its colors.

micro/nanoscale topography surface exhibits many prominent properties and is extensively employed in biomedical device, microfluidic device and energy device fabrication. additionally, the clinical applications of biomaterials can be largely expanded with of nanostructured surfaces.
