What is a Lava Chamber?
A hot spot is where a bum touches the earth
What is the definition of viscosity?
Viscosity is a fluid's resistance to flow. Fluids becomes less viscous as the liquid's temperature increases, becoming more viscous as the fluid gets cooler. A viscous fluid is sticky, thick and syrupy to a greater or lesser extent. Examples Treacle is quite viscous, but water is not. Hot engine oil is less viscous ('thinner') and runs more quickly and smoothly than cold engine oil.
Does lava really glow?
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)
Why do volcanoes hibernate?
Volcanoes that form islands over hot spots sometimes become dormant because they move away from the hot spot. If they move away from the hot spot, magma is no longer created.
Why are there different types volcanoes?
there are different types of volcanoes for different reasons. how they form has alot to do with the type of lava said volcano produces. fluid basaltic lava tends to create shield volcanoes. spatter cones tend to form when hot erupting lava contains just enough explosive gas to prevent the formation of a lava flow, but not enough to shatter it into small fragments. hot expanding gas tears the lava into hot fluid clots.
How is lava at divergent boundaries similar to lava at hot spot?
Yes.
What is that part of the earth that is relatively hot and that behaves as a highly viscous fluid?
The asthenosphere.

What is lava like?
Well,magma is hot moltten rock beneth earth's crust.If you touch it,well you know what happens-R.I.P.
What processes forms most mountains?
lava ozzing out of a vent which is a hot spot
Is block lava the same as pyroclastic flow?
No. Block lava is low-moving viscous lava, usually of andesitic or similar composition. A pyroclastic flow is a very fast-moving mixture of hot ash, rock and gas.

Which type of lava-basaltic lava or rhyolitic lava flows faster and why?
Basaltic flows much faster than rhyolite. Rhyolite is higher viscosity. Find a video of a basaltic lava flow like Hawaii, it flows like water when it's hot. Rhyolite eruptions usually act more like toothpaste if they're slow, or an explosion if fast.
Can you really swim in lava?
No. There are 3 reasons.Lava is extremely hot, and falling in lava would result in certain death.Lava is dense, about the same density as rock, so you would not sink in far enough to swim.Lava is viscous, so ignoring the first two reasons, it would be like trying to swim in molasses with the most fluid lavas.
