Question

Geologists studying a local rock formation measure the amount of matter in the rock. This measurement is known as the rock's __________.

mass
density
weight
gravity

Answer 1

The measurement is known as the rock's mass.

Step-by-step explanation:

The mass of an object is the quantity of matter that the object contains. It can be determined or measured by the use of; beam balance, top pan balance etc. The value of the mass of an object does not change regardless of its location on the surface of the earth or at other planets. the mass of object is measured in Kilograms.

Rock formation is a process by which a rock is formed. Either by sedimentation or cooling of magma. In studying the rock formation, the geologist measures the mass of the rock. He/ She would be able to know the amount of matter in the rock, which could be used to determine the weight of the rock.

Answer 2

Mass

Step-by-step explanation:

Mass is defined as the amount of matter in a substance. It is usually measured by balances such as the beam balance and scales. It is measured in grams or kilograms depending on the size of the body.

The process of Rock formation involves how a rock is formed which is usually by sedimentation or cooling of magma in volcanic eruptions. In rock formation study,the geologist measures the mass of the rock which enables knowledge of the amount of matter in the rock. This is be used to determine the weight of the rock and the rock type and properties.
