Runny lava contains low amounts of silicon, whereas sticky lava contains high amounts of silicon.
runny lava
Runny molten rock (low viscosity) is generally safer because it flows more easily and allows people to move out of the way faster. Sticky molten rock (high viscosity) tends to trap gases and pressure, leading to explosive eruptions.
Silica content of lava, as well as the temperature of the lava.
Some types do. Really runny lava, or hot lava, like Hawaiian-type lava, does glow because it's so hot (like when you heat a piece of metal). Really viscous (sticky) lava, however, has a solidifying skin on top because the lava has cooled down. It's sort of like custard (except custard never glows)
Layers of thin runny lava that flow over a wide area before they cool and harden can build up lava plateaus or volcanic fields.
well, since basaltic lava is the same material that composes the ocean floor, it is common sense that it would be sticky, not runny.
Lava is orange and runny
Lava can reach supersonic speeds in some highly explosive volcanic eruptions. Lava speed is mostly dependent on the lava's viscosity, whether it's runny or sticky. Most runny lava flows are probably less than 10 miles per hour. The more viscous, the slower the flow, depending on slope and other conditions.
Thick, highly viscous lava.

No. The lava there would be very viscous.
2. Thick or runny lava. Thick flows slowly, runny flows faster.
The typical cone shape of a volcano happens when sticky lava erupts upward. Sticky lava creates a dome shape and the lava cools slowly.
