Fred has an iq of 65 and cannot do schoolwork. he lives on the streets by begging, is usually dirty, and is always hungry. he would most likely be diagnosed with: a. dyslexic. b. intellectual disability. c. schizophrenic. d. depression

b. intellectual disability.

Explanation:

Intellectual disability is characterized by limitations in general mental skills. These skills are linked to intelligence, activities that involve reasoning, problem solving and planning, among others. Intelligence is assessed using the Intelligence Quotient (IQ) obtained by standardized tests. The result of a person with Intellectual Disability in this assessment is 75 or less. Like Fred who has an IQ of 65.

It is characterized by important limitations in both intellectual functioning and adaptive behavior, expressed in conceptual, social and practical skills. Individuals with Intellectual Disabilities have significantly lower than average intellectual functioning.

the earth’s crust is broken into separate pieces called tectonic plates (fig. 7.14). recall that the crust is the solid, rocky, outer shell of the planet. it is composed of two distinctly different types of material: the less-dense continental crust and the more-dense oceanic crust. both types of crust rest atop solid, upper mantle material. the upper mantle, in turn, floats on a denser layer of lower mantle that is much like thick molten tar.

each tectonic plate is free-floating and can move independently. earthquakes and volcanoes are the direct result of the movement of tectonic plates at fault lines. the term fault is used to describe the boundary between tectonic plates. most of the earthquakes and volcanoes around the pacific ocean basin—a pattern known as the “ring of fire”—are due to the movement of tectonic plates in this region. other observable results of short-term plate movement include the gradual widening of the great rift lakes in eastern africa and the rising of the himalayan mountain range. the motion of plates can be described in four general patterns:

collision: when two continental plates are shoved together

subduction: when one plate plunges beneath another (fig. 7.15)

spreading: when two plates are pushed apart (fig. 7.15)

transform faulting: when two plates slide past each other (fig. 7.15)
