There's a range for lava flow that stretches from a few inches to a number of miles. It depends mostly on a lava's viscosity. Highly vuc\\iscous lava volcanoes, such as Mt. St. Helens, tend to erupt violently, but lava flows are slow and quick to solidify. Underwater eruptions may have lava that solidifies on the outside almost instantly. Extremely low viscosity lava flows, like those in Hawaii, may run for days and cover miles before solidifying.

What are the four types of lava that form at hot spots and their characteristics?
Aa is lava that forms a thick ,brittle crust . Pahoehoe is a lava that forms a thin crust. Pillow lava forms when lava erupts underwater. Blocky lava is kool, stiff lava that does not travel far from thr eruption site.
Why does the lava from composite volcanos harden quickly?
Lava from composite volcanoes, or stratovolcanoes, is typically more viscous due to its higher silica content compared to basaltic lava from shield volcanoes. This increased viscosity means that the lava flows more slowly and doesn't travel far, allowing it to cool and solidify more quickly upon exposure to the atmosphere. Additionally, the steep slopes of composite volcanoes promote rapid cooling as the lava encounters cooler air and surface temperatures.
What are the streams of molten lava spilled out of a volcano called?
Streams of molten lava out of a volcano are called 'lava flows'.
Does a composite volcano have an Aa type of lava?
A'a can occur at composite volcanoes, but block lava flows, which are far more viscous, are more common.
Why does some types of lava travel faster than others?
Some types of lava travel faster than others primarily due to their viscosity, which is influenced by their chemical composition and temperature. Basaltic lava, for example, is low in viscosity because it contains less silica, allowing it to flow easily and quickly. In contrast, andesitic and rhyolitic lavas have higher viscosities due to their higher silica content, causing them to flow more slowly. Additionally, the temperature of the lava also affects its fluidity, with hotter lava generally being less viscous and able to travel further and faster.

How far can a car travel with ml of fuel?
A millilitre is one thousandth of a litre. Depending on the mpg the car gets, an average car would travel about as far as you could spit.

How far can your breath travel in a day?
The distance your breath can travel in a day can vary depending on factors like wind conditions, but on average, it may travel a few meters to tens of meters. In still air, it may not travel far at all before dispersing.
How far will a 40 caliber bullet travel?
It depends on several factors, but "about a mile" is a good average.
