| earthquake | show 🗑
|
||||
| Two powerful forces that change rock in Earth's crust are: | show 🗑
|
||||
| show | a force that acts on rock to change its shape or volume.
🗑
|
||||
| show | the amount of space an object takes up.
🗑
|
||||
| shearing | show 🗑
|
||||
| show | stress that stretches rock so that it becomes thinner in the center.
(related to divergent boundaries)
🗑
|
||||
| compression | show 🗑
|
||||
| If shearing continues to tug at the slab of rock, what will happen to the rock? | show 🗑
|
||||
| show | any change in the volume or shape in Earth's crust. Most changes in the crust occur so slowly that they cannot be observed directly.
🗑
|
||||
| How does deformation change Earth's surface? | show 🗑
|
||||
| show | Shearing - the rock breaks and slip apart
Tension - Rock stretches and becomes thin in center
Compression - Rock squeezes until it folds or breaks
🗑
|
||||
| show | A break in the crust where slabs of crust slip past each other.
🗑
|
||||
| show | Type of fault where rocks on either side move past each other sideways w/ little up-or-down motion.
🗑
|
||||
| show | Type of fault where the hanging wall slides downward; caused by tension in the crust.
🗑
|
||||
| hanging wall | show 🗑
|
||||
| show | The block of rock that forms the lower half of a fault.
🗑
|
||||
| show | Type of fault where hanging wall slides upward; caused by compression in crust.
🗑
|
||||
| What are the three types of fault? What force of deformation produces each? | show 🗑
|
||||
| show | Faults usually occur along plate boundaries, where the forces of plate motion compress, pull, or shear the crust so much that the crust breaks.
🗑
|
||||
| show | The force that opposes the motion of one surface as it moves across another surface.
🗑
|
||||
| What occurs when friction on a fault is low? | show 🗑
|
||||
| What occurs when friction on a fault is medium? | show 🗑
|
||||
| show | Sides of fault lock together and do not move. Stress increases until it it strong enough to overcome force of friction. Larger and/or more frequent earthquakes will occur.
🗑
|
||||
| fault-block mountain | show 🗑
|
||||
| show | Where two plates move away from each other, tension forces create many normal faults, when two normal faults form parallel to each other, block of rock is left lying between them. As the hanging wall of each normal fault slips down, the block moves up.
🗑
|
||||
| folds | show 🗑
|
||||
| show | Folding rock can fracture and produce faults.
🗑
|
||||
| show | An upward fold in rock formed by compression of Earth's crust.
🗑
|
||||
| show | A downward fold in rock formed by compression of Earth's crust.
🗑
|
||||
| show | A landform that has a more or less level surface and is elevated high above sea level.
🗑
|
||||
| How does movement along faults change Earth's surface? | show 🗑

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.
