3. Pedro threw a penny into a fountain and it sank to the bottom. Which of the following would explain
why the penny sinks?
A. The mass of the penny is more than the mass of the water.
B. The density of the penny is more than the density of the water.
C. The volume of the penny is more than the volume of the water.
D. The temperature of the penny is more than the temperature of the water.

its B because we're not talking about mass even tho most people would have chosen A cuz it says mass and u they would think its apart of density but if ur testing to see density ur figuring out which object will sink and which one will float so da reason why da penny snuck it cuz da density is greater den da water and copper has a better chance of sinking den floating so dats why its B I hope dis helps :3

B.

Explanation:

A is not correct as there is much more water then penny meaning the water has more mass. The same can be said about C as the water also has more volume. Answer D is incorrect as the temperature of the penny is irrelevant to its ability to sink. That leaves us with option B, which is true as the penny is composed of metal allowing it to sink in the water due to having more density.

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
