| What are the factors that determine the rate of weathering? | Composition, physical conditions, climate, topography, air pollution, exposure time, surface area.
🗑
|
||||
| Examples of physical weathering | Temperature, ice wedging, organic activity, Gravity, abrasion, exfoliation contraction
🗑
|
||||
| Examples of chemical weathering | Water, acid, oxidation
🗑
|
||||
| Weathering is | The breakdown of rocks
🗑
|
||||
| Erosion is | The movement of broken rocks
🗑
|
||||
| How/why does water cause chemical weathering | It dissolves minerals out of rocks making them weaker
🗑
|
||||
| What is abrasion | Rocks rubbing against other rocks
🗑
|
||||
| The more rounded a rock | The longer it is being tumbled or going through abrasion or in a stream/river
🗑
|
||||
| Surface area | The greater it is and that the greater the area is exposed to agents the greater rate of weathering
🗑
|
||||

|
||||
| Where is a streams velocity the greatest (curved( | Outside
🗑
|
||||
| Where is the streams velocity the greatest(straight) | Middle
🗑
|
||||
| Where does deposition occur | Inside
🗑
|
||||
| Where does erosion occur | Outside
🗑
|
||||
| What is the relationship between velocity of a stream and the size of the particles it can carry | Faster velocity =larger particles
🗑
|
||||
| Where do streams flow | Downhill
🗑
|
||||
| What two factors influence the velocity of a stream | Slope and volume
🗑
|
||||
| What does sorting look like | Slower flow of water smaller the particles
🗑
|
||||
| What causes sorting | Waters velocity
🗑

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.
