The physical property of a liquid is called viscosity.
Viscosity is the resistance
of a liquid to flowing.
All liquids have their own viscosity because they may
or may not resist to flowing.

The greater the viscosity, the slower it
flows….

The viscosity of magma
depends upon its silica
content and temperature.

What is silica?
Particles of the elements of silicon
and oxygen

High Silica = High Viscosity
(flows slow) and light colored rocks
Low Silica = Low Viscosity(flows fast) and dark
colored rocks

One example of light-colored rocks is
rhyolite.

One example of dark colored rocks is
called basalt.
