chronotypes

Explanation:

Chronotype is the behavior and preferred bodily and psychological schedule of one’s activity and sleep. It regulates what is the best time for someone to sleep during the day. The people who usually function at the night (like Patrick) prefer the eveningness and delayed sleeping period, while people who easily wake up and do their tasks early (like Molly) are more into morningness and advanced sleep periods.

Most people are flexible, and their schedules and types change in accordance with age, life stage, events, and tasks. However, chronotype also affects our traits, productivity, and effectiveness of our performance, and relaying which type is the best of us we can raise our productivity.

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)
