What is a long crack from which lava flows through?
fissure
Why does lava take a long time to cool down?
Lava cools slowly because lava is a poor conductor of heat. Lava flows slow down and thicken as they harden.
Long crack that forms as two tectonic plates move apart?
Long crack that forms as two tectonic plates move apart
How long would it take for lava to dry?
time!
What is a long tube that connects the magma chamber to the surface?
This is the description for the conduit of a volcano. Use the link below for more information, including a diagram.Dont listen to that because that's not true its the pipe and if it's not that then its the vent:)

How long can magma flow until cooling?
Magma flows for a long period of time but named lava when out of the ground. It depends how fast the lava is travels, but you can usually run from it:)
What is long crack where plates diverge?
Itis called a rift.
A long narrow crack in earth crust is called?
Fault
How does the viscosity affect of lava affect its flow rate?
Viscosity means how runny it is. Thus a lava with low viscosity will erupt fast and form long, wide spreading lava flows (eg Hawaii) and lavas of high viscosity will erupt slowly and form lava domes (eg Mt. St. Helens).
How does the type of material that erupts from a volcano determine the shape of the volcano?
The shape tells a geologist how viscous (thick and sticky) the lava was. A taller volcano, such as a cone, was formed by thicker lava; a low volcano, such as a shield volcano, was formed by very runny lava.
How do scientists predict a flow of lava?
Scientists can often find clues about past eruptions by studying the deposits left behind. Areas affected by lava flows, debris flows, tephra, or pyroclastic flows can be mapped, making disaster planning more effective. In addition to this type of long-range forecasting, scientists are becoming more and more skilled at spotting the warning signs of an eruption.
Why doesnt the type of eruption that produce a lava plateau produce a volcanic mountain instead?
first lava flows out of several long cracks in an area. the thin runny lava travels far before cooling and solidifying. again and again floods of lava flow on top of earlier floods. After millions of years these layers of lava can form high plateaus!

What are lava plateau volcanoes?
First, lava flows out of several long cracks in an area. The thin, runny lava travels far before cooling and solidifying. Again and again, floods of lava flow on top of earlier floods. After millions of years, these layers can form high plateaus.
How long did the lava flow last of the 1980 Mt St helens eruption last?
There were no lava flows associated with the 1980 eruption. The eruption instead produced a massive eruption column and pyroclastic flows. This eruption lasted for 10 hours. A series of smaller explosive and dome-building eruptions continued from six years.
What type of lava do shield volcano have?
Mafic, usually basaltic lava.
