jill has found evidence that suggests that individual volcanoes produce igneous rocks with a certain chemical signature. she predicts that scientists could use an igneous rock's chemical signature to determine where the rock came from. what type of investigation should jill perform to test her prediction?
a.
model the formation of an igneous rock
b.
observe and describe a volcanic eruption
c.
collect and test rock specimens
d.
perform a controlled experiment on a volcano

The answer is C on study island Collect and test rock specimens

Explanation:

Different scientific questions and predictions require different types of scientific investigations. Some questions can be answered through controlled experiments. Other questions can be answered through collecting specimens, building models, and/or making observations.

Jill's prediction could best be tested by collecting and testing rock specimens from multiple volcanoes in various locations.
