How does the composition of lava influence its flow behavior and the resulting landscape?
All lava flows move at the same speed regardless of composition or temperature.
Lava low in silica is more fluid and travels farther, creating extensive flows, while silica-rich lava is thicker and forms steep domes or thick flows.
Lava composition does not affect how it cools or the type of rock it forms.

How does the chemical composition of lava affect its flow characteristics?
It changes the lava's temperature but not its flow speed.
It influences the lava's viscosity, determining how fast or slow it flows.
It only affects the color of the lava, not its movement.
