Which have scientists learned from studying seismic waves that travel through earth’s interior? A. Earth's mantle is liquid. B. Seismic waves cannot move through solid objects. C. Seismic waves are not affected by boundaries between earth's layers. D. The outer core of earth is liquid.

Answers

What scientists learned about Earth by studying seismic waves is “Seismic waves are not affected by boundaries between earth's layers”.  The correct answer is C.

Scientists studied the seismic waves to be able to properly understand the Earth’s interior. Seismic waves refer to wave energy that moves through the Earth.

Further Explanation

Their movement is also typical or similar to other types of waves like water, light and sound waves.  

These waves of energy travel through the earth during earthquakes and cause the ground to vibrate.

A seismograph is the type of machine used to record the speed and strength of Seismic waves. The recordings made available by seismographs are known as seismograms. The machines have made it possible for scientists to understand that the speed at which seismic waves move through the earth is different.

Seismic waves can, however, be divided into two, which include:

  1. Body waves
  2. Surface waves.

Body waves move through the earth’s interior while the surface waves move through the earth’s surface. Surface waves are very important types of seismic waves but they don’t provide information as to what is going on in the Earth’s interior.

Therefore, what scientists learned about Earth by studying seismic waves is “Seismic waves are not affected by boundaries between earth's layers”.

Curtis's loss of interest in his grandfather's picture demonstrates a) continued response b) operant response c) recovery from habituation d) habituation of attention.

Answers

d) habituation of attention          

Explanation:

Habituation of attention: One of the forms of learning, in which a person gets habituation from a piece of information after being encountered repeatedly that no longer the information bothers the person's consciousness.

This is what exactly has happened in the case of Curtis, that he loses interest in his grandfather's picture after the repeated exposure to it.

The phenomenon explains that there is a declination or decrements in the occurrence of a particular behavior after getting a repeated exposure to a given stimulus that causes the behavior.
