Teri is a new mother who is home alone with her infant. she feels extreme stress from her routine that includes nursing constantly, trying to keep up with the loads of laundry, annoying phone calls from her mother, isolation, and getting to what seem to be constant doctor appointments. this is an example of:

Daily stresses.

Teri is a new mother so she has new responsibilities and new stresses added into her daily life/routine which is already busy and stressful. This is very common and very similar for many women, once a baby comes along a lot more work and stress is created and it's about trying to balance everything and deal with these stresses. There is no indication here that Teri is mentally unwell post natally just very stressed out from her new daily life.

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)
