Principal of Superposition

What is the Principle of Superposition?

• that layers of sediment initially extend laterally in all directions; in other words, they are laterally continuous.

• the principle that in a series of stratified sedimentary rocks the lowest stratum is the oldest

• social organization that holds that social and political issues should be dealt with at the most immediate (or local) level that is consistent with their resolution.

• waves will be faster at higher magnitude

What is the interference (geo)?

• the action of interfering or the process of being interfered with wavelength.

• a thing placed at the rear of something as a barrier or support.

• the point where two waves meet each other at a particular point. The following picture demonstrates interference.

• an insurance policy for waves

Name a type of Interference

• Constructive

• a barier

• neutral

Name another type of Interference

• cohesion

• Destructive

• a wall

• adhesion

What is Constructive interference?

• when the resultant displacement from rest is larger than the individual wave's displacement.

• occurs when the resultant displacement from rest is smaller than the individual wave's displacement from rest.

• When two waves interfere (meet each other at a particular point) the resulting wave will be the sum of the individual waves, at each point.

What is destructive interference?

• he attractive forces between unlike molecules. They are caused by forces acting between two substances

• intermolecular attraction that explains the process of water flow upwards (against the force of gravity) through the xylem of plants.

• occurs when the resultant displacement from rest is smaller than the individual wave's displacement from rest.
