What is density?

Back

Density is the mass of an object divided by its volume, often expressed in grams per cubic centimeter (g/cm³).

Front

Which state of matter is generally the most dense?

Back

Solid is generally the most dense state of matter.

Front

What is the composition of the Earth's inner core?

Back

The inner core is primarily composed of iron and nickel.

Front

Which layer of the Earth is the least dense?

Back

The crust is the least dense layer of the Earth.

Front

What happens to density as you go deeper into the Earth?

Back

Density generally increases as you go deeper into the Earth.

Front

Why do different liquids form layers when mixed?

Back

Different liquids form layers because they have different densities.

Front

What is the outer core made of?

Back

The outer core is made of liquid iron and nickel.

Front

Which layer of the Earth has the highest density?

Back

The inner core has the highest density.

Front

What is the mantle?

Back

The mantle is the layer of the Earth between the crust and the outer core, composed of semi-solid rock.

Front

How does temperature affect density?

Back

Generally, as temperature increases, density decreases because substances expand.
