|---|---|---|---|---|---|
| crust | the outmost layer of the earth is the crust it is 5 to 100 km thick
🗑
|
||||
| mantle | the layer of earth between the crust and the core contains most of earths mass
🗑
|
||||
| core | the layer of the earth that extends from below the mantle to the center of the earth
🗑
|
||||
| lithosphere | the outmost rigid layer of the earth
🗑
|
||||
| asthenosphere | a plastic layer of the mantle on which pieces of lithosphere move made of solid rock
🗑
|
||||
| mesosphere | extends from the bottom of the asthenosphere to the earth's core
🗑
|
||||
| tectonic plate | a block of lithosphere that consists of the crust and the rigid outmost part of the mantle
🗑
|
||||
| continental drift | the hypothesis that states the continents once formed a single land mass broke up, and drifted to their present locations
🗑
|
||||
| Pangaea | existed when some of the earliest dinosaurs roamed the earth - a continent surrounded by a sea called panthalassa
🗑
|
||||
| Laurasuia - Gondwana | two continents that Pangaea broke up into
🗑
|
||||
| Eurasia | a continent that used to be connected to North America but separated from the other continents we know today
🗑
|
||||
| sea floor spreading | process by which new oceanic lithosphere forms as magma rises toward the surface and solidifies
🗑
|
||||
| Plate tectonics | the theory that the earths lithosphere is divided into tectonic plates that move around on top of the asthenosphere
🗑
|
||||
| convergent | when two tectonic plates collide
🗑
|
||||
| divergent boundary | when two tectonic plates separate
🗑
|
||||
| transform boundary | when two tectonic plates slide past each other horizontally
🗑
|
||||
| gps | also known as the global positioning system uses radio waves to sense things happening on earth
🗑
|
||||
| ridge push | when the oceanic lithosphere slides downhill under the force of gravity
🗑
|
||||
| slab pull | when oceanic lithosphere sinks and pulls the rest of the tectonic plate with it
🗑
|
||||
| convection | causes the oceanic lithosphere to move sideways and away from the mid ocean ridge
🗑
|
||||
| compression | type of stress that occurs when an object is squeezed such as when two tectonic plates collide
🗑
|
||||
| tension | is sress that occurs when forces act to stretch an object
🗑
|
||||
| folding | the bending of rock layers because of stress in the earth's crust
🗑
|
||||
| fault | is a surface along which rocks break and slide past each other
🗑
|
||||
| uplift | the rising of regions of the earth's crust to higher elevations
🗑
|
||||
| subsidence | the sinking of regions of the earth's crust to lower elevations
🗑

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.
