Lava flows produced by eruptions under water are called pillow lavas. If the viscosity is high, but the gas content is low, then the lava will pile up over the vent to produce a lava dome or volcanic dome. Explosive Eruptions. Explosive eruptions are favored by high gas content & high viscosity magmas (andesitic to rhyolitic magmas).
Medical Definition of intelligence. 1  1a: the ability to learn or understand or to deal with new or trying situationsb: the ability to apply knowledge to manipulate one's environment or to think abstractly as measured by objective criteria (as tests) 2  2: mental acuteness.
IQ testing is a method used by psychologists to measure what is generally considered intelligence. The concept of IQ, or Intelligence Quotient was first introduced by French psychologist Alfred Binet in 1904. The quotient refers to Binet's definition of IQ as (Mental Age) divided by (Chronological Age) or M.A./C.A.This quotient is then multiplied by 100 to make it a whole number. An 8 year old child with the mental ability of a 12 year old has a mental age which is 1.50 times his chronological age (12/8 = 1.5).odern IQ tests use a deviation IQ rather than a ratio IQ. With this method, test takers are referenced to other people of their own age. The average IQ is still 100, but deviations from the average are assigned a number which corresponds to a percentile rank.
