A biology class wanted to study the effect of different materials on the melting rate of ice. They placed pieces of ice, each wi

th a mass of 10g, onto trays. Group 1 was covered in plastic, group 2 was covered in paper, group 3 was covered in aluminum, and group 4 remained uncovered. Each piece of ice was allowed to melt for 15 minutes. Then final mass of the ice, minus the melted water, was recorded at the end of the experiment. What is the dependent variable in this experiment?

The dependent variable is what you are measuring. You are measuring the mass of the ice at the end of the 15 minutes, therefore, your dependent variable is the mass of the ice.

Anuta_ua [19.1K]

Answer;

-Non-foliated metamorphic rocks

-Metamorphic rocks that don’t have layers are called non-foliated metamorphic rocks.

Explanation;

-Metamorphic rocks are rocks that go through heat and pressure and change form. They can be formed by pressures deep inside the Earth, by tectonic processes such as continental collisions, or when they are heated up by an intrusion of hot molten rock called magma from the Earth's interior.

-Foliated metamorphic rocks have a layered or banded appearance that is produced by exposure to heat and directed pressure, they include rocks such as gneiss, phyllite, schist, and slate.

-On the other hand,Non-foliated metamorphic rocks do not have a layered or banded appearance, they include rocks such as hornfels, marble, quartzite, and novaculite.
