3. California, Minnesota, Florida, Alaska, Utah, Missouri, Michigan, Wyoming and Georgia.
4. The shape of a mineral crystal reflects the arrangement of atoms which compose it.
5. Fossils found in a particular rock layer help scientists determine the age of the rock.
Explanation:
1. -
2. Rubbing the mineral on a streak plate will produce a streak
3. In 2020, 12 states each produced more than $2 billion worth of nonfuel mineral commodities. The states, ranked in descending order of production value, were: Nevada, Arizona, Texas, etc.
4. The nature of this arrangement is affected by the size of the atoms and how they bond together. Mineral breakage is also determined by atomic arrangement; some minerals cleave along weak planes in the atomic structure.
5. The location of fossils in rock layers provides evidence of Earth's past landscapes. It is hard to guess the age of rock. Scientists have to act like detectives, piecing together a mystery to determine how long ago rocks formed.
