Question

Jill hypothesizes that individual volcanoes produce igneous rocks with a certain chemical signature. She further hypothesizes 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 hypothesis? A. perform a controlled experiment on a volcano B. model the formation of an igneous rock C. collect and test rock specimens D. observe and describe a volcanic eruption

Answer 1

collect and test rock specimens

Step-by-step explanation:

Answer 2

The correct option is (C)

Step-by-step explanation:

Hypothesis is referred to as an assumption or wild guess that needs to be tested to arrive at a scientifically established theory,

Here, Jill proposes a hypothesis which states that igneous rocks produced by volcanoes constitute some kind of chemical that could be used by scientists to estimate the origin of the rocks.

This hypothesis can be tested only by collecting the rock samples and testing them to arrive at a scientifically proven fact.
