What type of stress is most likely to occur at the San Andreas Fault?
What type of stress is most likely to occur at the San Andreas Fault? Shear Stress Friction between the plates grinding past one another produces the stress. Shear stress is associated with transform faults, which may also be called strike-slip or slip-strike faults. Perhaps the most well-known example of shear stress is the strike-slip fault […]

What 4 elements at room temperature can become permanently magnetized?
What 4 elements at room temperature can become permanently magnetized? There are only four elements in the world that are ferromagnetic at room temperature and can become permanently magnetized: iron, nickel, cobalt and gadolinium. (A fifth element, dysprosium, becomes ferromagnetic at low temperatures.) What happens when a watch is magnetized? Magnetization is a particular problem […]
Do gamma rays travel faster than light?
Do gamma rays travel faster than light? Although the energy inherent to light is quantized into discrete energy packets (a.k.a., photons), there are some properties shared by all forms of light. Light of any wavelength, from picometer-wavelength gamma-rays to radio waves more than a trillion times longer, all move at the speed of light in […]
What forces act on a still object?
What forces act on a still object? Force is defined as a push or pull acting on an object. Forces include gravity, friction, and applied force. Force causes changes in the speed or direction of motion. These changes are called acceleration. What forces can change the shape of an object? When a force acts on […]
