According to Table 2, as the temperature of any given magma composition decreases, its viscosity: Passage Context (Planetary Geology): Geologists tested the relationship between silica (SiO2) weight percentage, temperature, and magma viscosity (measured in poise) for three volcanic magma compositions: Table 2: - Basaltic Magma (48% SiO2): 1200°C -> 100 poise | 1100°C -> 1,000 poise | 1000°C -> 10,000 poise - Andesitic Magma (58% SiO2): 1100°C -> 30,000 poise | 1000°C -> 250,000 poise | 900°C -> 3,000,000 poise - Rhyolitic Magma (72% SiO2): 1000°C -> 10,000,000 poise | 900°C -> 100,000,000 poise | 800°C -> 1,000,000,000 poise

Look at the numbers as temperature drops: 100 -> 1,000 -> 10,000. Viscosity increases.

For basaltic magma: 1200°C (100 poise) -> 1000°C (10,000 poise). For andesitic and rhyolitic magmas, viscosity also increases by multiples of 10 as temperature drops....
