|---|---|---|---|---|---|
| faults | a large fracture in rocks, form several meters to many kilometers long, where rocks not only crack but also move along either side of the break.
🗑
|
||||
| earthquakes | the movement of the ground, caused by waves from energy released as rocks move along faults
🗑
|
||||
| normal fault | a pull-apart (tension) fracture in rocks, where rocks that are above the fault surface drop downward in relation to rocks that are below the fault surface.
🗑
|
||||
| reverse fault | a compression fracture in rocks, where rocks that are above the fault surface are forced up over rocks that are below the fault surface.
🗑
|
||||
| strike-slip fault | a break in rocks where rocks on either side of the fault move past each other (instead of above or below each other).
🗑
|
||||
| seismic waves | the energy waves that make the ground quake during an earthquake
🗑
|
||||
| focus | in a earthquake, the point in earth's interior where movement releases energy to cause the earthquake.
🗑
|
||||
| primary waves | waves of energy, released during an earthquake, that travel through earth by compressing particles in rocks in the same direction the wave is traveling.
🗑
|
||||
| secondary waves | waves of energy, released during an earthquake, that travel through earth by moving particles in rocks at right angels to the direction the wave is traviling
🗑
|
||||
| epicenter | the point on earth's surface directly above an earthquake's focus
🗑
|
||||
| surface waves | waves of energy, released during an earthquake, that reach Earth's surface and travel outward from the epicenter in all directions
🗑
|
||||
| Moho discontinuity | the boundary between Earth's crust and the upper mantle; seismic waves travel slower above the Moho and faster below it.
🗑
|
||||
| seimologists | a scientist who studies earthquakes and seismic waves
🗑
|
||||
| seismograph | an instrument that records earthquake waves
🗑
|
||||
| magnitude | in earthquake studies, a measure of the energy released by an earthquake
🗑
|
||||
| tsunamis | an ocean wave caused by an earthquake
🗑
|
||||
| seismic-safe | describes structures that are resistant to movements from an earthquake
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
