Volcanic gases are more abundant in felsic lavas than mafic lavas. are not harmful because most are less dense than air. o killed over 1,700 people at Lake Nyos, Cameroon, Africa, in 1986. O are released by magma as it rises and the pressure decreases. Question 9 1 pts Over an eight-month period in 1783 and 1784, a massive effusive eruption took place at the Laki volcano in Iceland. Although there was relatively little volcanic ash involved, a massive amount of sulphur dioxide was released into the atmosphere, along with a significant volume of acid. The poisoning from this acid resulted in the death of 80% of sheep, 50% of le, and the ensuing famine, in more than 10,000 human deaths in Iceland. What was this acid? carbonic O hydrochloric O hydrofluoric O sulfuric Question 10 1 pts Lahars, composed of ash, debris, and water occur only in arctic regions because snow supplies the water for mud. 9:37 PM Sun Sep 26 15% 4 Take Quiz Exit Question 23 3 pts Match the volcano type with its correct plate tectonic setting Cinder Cone [ Choose ] Composite (Stratovolcano) [ Choose ] Shield Volcano V [ Choose] Large Igneous Provinces (LIPs) [ Choose ] Seafloor Volcanism [ Choose ] Question 24 1 pts As magma approaches the surface, the pressure exerted on it decreases. Gas bubbles start to form, and the more gas there is in the magma, the more bubbles form. If the magma is runny enough (low viscosity) for gases to rise up through it and escape to surface, the pressure will not become excessive. Assuming that it can break through to the surface, the magma will flow out relatively gently. An eruption that involves a steady non-violent flow of magma is called O phreatic effusive clumpy O pyroclastic 9:37 PM Sun Sep 26 15% 4 Take Quiz Exit Question 23 3 pts Match the volcano type with its correct plate tectonic setting Cinder Cone [ Choose ] [ Choose ] Composite (Stratovolcano) Subduction Zones (Convergent Margins) Shield Volcano Various tectonic settings Mostly Spreading Ridges, some Mantle Plumes Large Igneous Provinces (LIPs) Mostly Mantle Plumes, some Spreading Ridges Seafloor Volcanism "Super" mantle plumes Question 24 1 pts As magma approaches the surface, the pressure exerted on it decreases.

As the magma approaches the surface, the pressure exerted on it allows the gases to separate from the magma. The word that describes the gas separation from the magma is (Mentioned on the page with Figure 4.2.3) exsolve effusive divergence O liquidus Question 27 1 pts The relationships between plate tectonics and volcanism are shown on Figure 4.1.2.
