|---|---|---|---|---|---|
| Law of Inertia (Newton's 1st Law) | An object in motion will stay in motion unless acted on by an outside force OR an object at rest will stay at rest unless acted on by an outside force
🗑
|
||||
| Real Life examples of Inertia | *dishes on a tablecloth *billiards *car braking
🗑
|
||||
| Action - Reaction (Newton's 3rd Law) | for every action, there is an equal and opposite reaction
🗑
|
||||
| Examples of action - reaction | *space shuttle *gun firing *bike or car tire goes one way, car goes in the oppostie direction
🗑
|
||||
| Force | any push or pull (examples: gravity and friction)
🗑
|
||||
| Pressure | force acting on a given area; more force = more pressure
🗑
|
||||
| What causes earthquakes? | pressure being released inside the earth
🗑
|
||||
| How does an earthquake happen? | pressure is built up as a result of forces on rocks underground
🗑
|
||||
| Elastic limit | the amount of pressure an object can withstans and still return to its original shape (think of a rubberband) If the elastic limit is passed, it breaks, sending vibrations through the earth = earthquake occurs
🗑
|
||||
| Fault | A fracture in the earth where rock movement occursfound at the surface as well as deep below the surface
🗑
|
||||
| Normal Fault | Tension causes it.....means the rocks are pulling apart (know drawing in notes)...movement is up/down
🗑
|
||||
| Reverse Fault | (reverse of a normal fault) Compression causes it....rocks are push or "press" together..movement is up/down
🗑
|
||||
| Strike-slip Fault | Shearing of the rock (like scissors). The rocks slide past each other...no up/down. movement is side to side
🗑
|
||||
| Compression wave | matter is squeezed together; think of an accordian
🗑
|
||||
| Transverse wave | matter that moves at right angles to the direction the wave is moving; think of a heart monitor or seismograph
🗑
|
||||
| seismic waves | waves generated by earthquakes
🗑
|
||||
| focus of earthquake | point inside the earth where seismic waves start
🗑
|
||||
| primary seismic waves | compression waves; travel faster and arrive first
🗑
|
||||
| secondary seismic waves | (aftershocks); transverse waves; travel slower and arrive second; do more damage
🗑
|
||||
| epicenter | point on the earth's SURFACE directly above the focus
🗑
|
||||
| surface waves | waves generated when seismic waves reach the surface;move slower than primary and secondary waves;cause the greatest damage (like ripples on water)
🗑
|
||||
| What happens when lava cools? | cools around th event, creating different shapes
🗑
|
||||
| Calm Eruption | thin magma, lamost water-like; magma is released gently out of a vent; oozes
🗑
|
||||
| violent eruption | very thick magma; magma clogs the vent creating a buildup of pressure; sudden release of magma
🗑
|
||||
| shield volcano | gentle slope; formed from hot, thin lava; no violent eruptions; lava erupts out of more than one vent
🗑
|
||||
| cinder cone volacno | ash and cooled lava form a steep cone, lava from one vent, violent eruption
🗑
|
||||
| Composite Cone volcano | steep-sided towering mountains; alternating gentle and eviolent eruptions, formed from hardened lava, flowing lava, and ash
🗑

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.
