An example is like if you taped a block in a box, put a marble inside of the box, and closed the lid. Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. Seismographs are equipped with electromagnetic sensors that translate ground motions into electrical voltages. What is Earth Science? Other seismologists study the seismic waves generated by much more powerful sources: natural, like earthquakes and mining events, or artificial, like underground nuclear tests. .

Seismographs can detect quakes that are too small for humans to feel. S-waves (S stands for secondary) are shear earthquake waves that pass through the interior of the Earth. Primary waves (also called P-waves) are fastest, traveling at about 6 to 7 kilometers (about 4 miles) per second, so they arrive first at the seismometer. Find the value of x that will ensure that the quadrilateral VWXY is a parallelogram. Which sources do scientists use to study the interior of Earth?
