Heat effects the flow rate of lava because the hotter the lava is, the less viscous it is which allows it to flow faster than if it had a slow flow rate. If it has a low temperature, then the flow rate will be much slower because it has a high viscosity.

A lava flow cool as it moves away from the venthow would this affect the surface appearance of the lava flow?
Yes, each layer of overlapping lava cools down with the other creating a ripple-like appearance after the lava becomes rock
What is the density independent of lava flow?
the lava flow is a density independent that flow good from the chemicals lava it have to flow and it is independent
Is there a difference between lava and lava flow?
Lava is molten rock at earth's surface, whether it is in a lava flow, a lava pool, or a lava dome. A lava flow is lava that is actively flowing downhill.
How does lava cool on top of lava?
Lava on Earth's surface is exposed to air, which is of course much cooler than the lava. The air then carries heat away from the surface of the lava flow rather quickly. Since rock, molten or otherwise, is a poor conductor of heat the interior of the lava flow cools much more slowly and does not supply heat to the cooling outer layer. As a result the lava forms a thing solid crust. Until a thick insulating crust has built up the surface will remain quite hot, just not hot enough to be molten.
Is dike a type of lava flow?
No, a dike is not a type of Lava flow.
How does the temperature of lava affect how far the lava will flow?
The hotter it is, the longer it takes to cool off, and the further it can flow.
How does the shape of a volcano affect the flow of lava?
SGV
How does gravity affect the lava flow?
As a physycist, I can assure you this has no effect.
How does temperature affect how well magma will flow?
It affects the rate of flow of the lava. Hotter means faster flow
A lava flow cool as it moves away from the venthow would this affect the surface appearance of the lava flow?
Yes, each layer of overlapping lava cools down with the other creating a ripple-like appearance after the lava becomes rock
What 3 factors affect the formation of lava?
Composition, heat, and pressure.
Can intense heat form a cave?
no +_++ With one exception, the Lava Tube! This results from still-molten lava flowing out from beneath the solidified crust on a mahjor lava flow.
What is the density independent of lava flow?
the lava flow is a density independent that flow good from the chemicals lava it have to flow and it is independent

Would lava flow on Earth in a vacuum?
Yes. In fact the lava would cool more slowly as it would not lose heat though convection.

What is silicia and how does it affect how well magma will flow?
The more silica, the slower the lava flows and the more viscous it is.
