Perfect for geology lessons, these printable flash cards address issues related to erosion.
There are 16 flash cards in this set (3 pages to print.)
1. Print out the cards.
2. Cut along the dashed lines.
3. Fold along the solid lines.
Sample flash cards in this set:
|Erosion||When something slowly gets worn off like rocks in a river.|
|Hydraulic Action||A type of erosion that happens when water erodes the side of the river transporting the sediment down the river.|
|Attrition||A type of erosion rocks smash into each other creating smaller rocks that continue the cycle.|
|Abrasion||A form of erosion in a river where rocks gring along each other creating very small pieces of sediment where it is transported down the river.|
|Solution||Where rocks like limestone slowly dissolve into the water to make very, very small pieces of sediment.|
|Arch||An arch that is created when waves smash into the back of a cave to make their way through.|
|Stack||A rock that has been deposited out at sea from the rock that was underneath the arch.|
|Stump||A stack that has been eroded away from waves.|
|Cave||Hydraulic action has eroded the weaker bits of a cliff and caved it in to make a cave.|
|Longshore Drift||Waves hitting a beach at an angle than back at a 90 degree angle carrying sediment as it goes along.|
|Bars||Where a spit grows across a bay and maybe enclose it to make a lagoon.|
|Spits||A narrow line of sand that has been created by longshore drift that is connected to the land on one end but not the other.|
|Beaches||Where sand has been deposited on land.|
|Tombolos||A spit that has been connected to an island from the mainland.|
|Hard Engineering||Techniques that protect a cliffside or beach from the power of waves to avoid erosion.|
|Soft Engineering||Where a shoreline is being protected with an environmental approach like putting more sand on a beach.|
