Density & Layers of the Earth

Front

What is density?

Back

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

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.

Front

What is the density of water?

Back

The density of water is 1.0 g/cm³.

Front

Which materials will float on water?

Back

Materials with a density less than 1.0 g/cm³ will float on water.

Front

What is the least dense layer of the Earth?

Back

The crust is the least dense layer of the Earth.

Front

What is the thinnest layer of the Earth?

Back

The crust is the thinnest layer of the Earth.

Front

Why does a brick sink in water while a wooden block floats?

Back

A brick sinks because it has a higher density than water, while a wooden block has a lower density.

Front

What is the density of lamp oil?

Back

The density of lamp oil is 0.80 g/cm³.

Front

What is the density of honey?

Back

The density of honey is 1.30 g/cm³.

Front

What is the relationship between density and buoyancy?

Back

An object will float if its density is less than the fluid it is in; it will sink if its density is greater.
