Is density useful in identifying unknown substances?

Yes

Explanation:

You can identify an unknown substance by measuring its density and comparing your result to a list of known densities.

Density = mass/volume

When you divide the mass by the volume and compare the density to a list of known densities.

Density can be used to identify an object by discovering the mass of your object on the scale, then finding the capacity of an item with a uniform shape. 2

Explanation:

You can identify an unknown substance by measuring its density and comparing your result to a list of known densities. Density = mass/volume. Assume that you have to identify an unknown metal. You divide the mass by the volume and compare the density to a list of known densities. Density is one of the properties that can be used to identify an unknown metal. As you know, density is the ratio of mass to volume. In equation form: Density K Mass J Volume. these measurements, you will calculate the density of the unknown metals.

I hope that helped have a nice day!!

explanation:

plate tectonics and volcanic euptions

over time, plate tectonic processes cause continents to move to different positions on the globe.

for example, britain was near to the equator 300 million years ago, and therefore was hotter than it is today. for further details look at our climate through time poster or online map.

the movement of the plates also causes volcanoes and mountains to form and these too can contribute to a change in climate.

mountain ranges formed by plate tectonics. large mountain chains can influence the circulation of air around the globe, and consequently influence the climate.   warm air might be deflected somewhere cooler by the mountains.

they both go up but then go back down. they both end lower than they started. lastly, they both are competitive/the second on.
