Video lecture on wave motions and speeds of three fundamental kinds of seismic waves: Primary (P = pressure) waves; Secondary (S = shear); and Surface waves. [3:10]
How do seismologists monitor a situation in New Mexico? Check out this clip illustrating the Socorro Magma Body study. [4:19]
Islands in the south Pacific are recognized for particular features which nurture earthquakes. A video will illustrate tectonic microplates found in the region. [4:09]
Oblique view of a highly generalized animation of a subduction zone where an oceanic plate is subducting beneath a continental plate. [0:27]
Video lecture on four basic types of plate tectonic boundaries: divergent (spreading), transform (strike-slip), and convergent (subduction and continental collision) types of plate boundaries. [2:03]
Video introduces mantle convection which is the slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior of the Earth to the surface. It goes on to explain how the Earth's internal heat is the energy source for plate tectonics and gravity forces are what move the plates. [6:54]
Video lecture describing speeds and paths of different seismic waves within Earth from an earthquake to a distant seismic station. P & S waves travel through the Earth; Surface waves travel around the perimeter of the Earth. [1:44]
Probe into the technique used to measure ground deformation indicative of volcanic activity. Check out this quick clip illustrating the function of InSAR and how it helped identify activity in Oregon. [0:42]
Find the connection between earthquakes and volcanoes. This clip will illustrate volcanic earthquakes. [1:44]
This lesson describes the function and components of the human nervous system. It helps students understand the purpose of our brain, spinal cord, nerves and the five senses. How the nervous system is affected during spaceflight is also discussed in this lesson.
This tutorial looks at the anatomy of the eye and how the sense of sight works. This is the first part of a learning module. Subsequent sections cover how images are formed and detected, the concept of accommodation where the eye adjusts its focus, and how farsightedness and nearsightedness are corrected. Includes detailed calculations using physics formulas, e.g., to find the quantitative relationship between the object distance, image distance, and focal length.
Psychology is designed to meet scope and sequence requirements for the single-semester introduction to psychology course. The book offers a comprehensive treatment of core concepts, grounded in both classic studies and current and emerging research. The text also includes coverage of the DSM-5 in examinations of psychological disorders. Psychology incorporates discussions that reflect the diversity within the discipline, as well as the diversity of cultures and communities across the globe.Senior Contributing AuthorsRose M.

By the end of this section, you will be able to:
Describe the basic anatomy of the visual system
Discuss how rods and cones contribute to different aspects of vision
Describe how monocular and binocular cues are used in the perception of depth
Describes the important structures of the human eye and how they work so that we can see images. [4:47]
