| THEORY OF PLATE TECTONICS | theory states that Earth's lithosphere is broken into huge, moving slabs of rock driven by motions in the mantle.
🗑

🗑
|
||||
| RIFT VALLEY | a deep valley formed as tectonic plates move apart
🗑
|
||||
| MAGNETIC REVERSAL | switch in the direction of earth's magnetic field so that the magnetic north pole becomes the magnetic south pole and the magnetic south pole becomes the magnetic north pole
🗑
|
||||
| CONVERGENT BOUNDARY | a boundary along which two tectonic plates push together, characterized either by subduction or a continental collision
🗑
|
||||
| TRANSFORM BOUNDARY | boundary along which two tectonic plates scrape past each other and crust is neither formed nor destroyed
🗑

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.
