<h3>Answer:  C. a balance and a beaker</h3>

Explanation:

A balance would be used to measure the weight, which in turn effectively measures the mass (more or less). Imagine that we have a brick that we know is 1 pound. If we have an object that needs 5 bricks on one side to balance it out, then we know the object is 5 pounds.

The beaker is used to measure the volume. It's basically a measuring cup that you would find in the kitchen.

To get the density, you divide the mass over volume.

For example, if you have a material that has a mass of 100 grams and it's volume is 20 cm^3, then its density is 100/20 = 5 grams per cm^3.

What would happen to the oceans if continental and oceanic crust had the same density?
levacccp [35]

Answer:

The oceanic crust is formed by partial melting of the mantle at mid-ocean ridges. The continental crust is formed even more cycles of partial melting over time, resulting less dense rocks.

Explanation:

The mantle, oceanic crust, and continental crust all have different compositions due to a process called partial melting.

This is where you start to melt a rock, but don´t melt it all the way.

When you partially melt a rock, certain chemical elements tend to stay in the solid rock while others tend to go into the melted part.

As a result, the rock that forms from that melt is less dense than the original rock.

If you then partially melt that rock, you get a rock that is even lighter.
