The sixth scenario, "A lot of rain quickly or the rapid melting of snow will cause a landslide," is an example of erosion. A landslide involves the rapid downslope movement of rock, soil, and debris under the influence of gravity. The heavy rain or rapid snowmelt saturates the ground, reducing friction and causing the material to slide downhill. This is a form of mass wasting, which is a type of erosion that moves large amounts of material quickly.
Now I have analyzed all six scenarios on the worksheet. I will summarize my findings to provide a complete answer.
Based on my analysis of each scenario, here are the correct classifications:
1.
Ice wedging into the rock and breaking and cracking the rocks and soil:
Weathering.
* *Explanation*: This is physical weathering where water freezes in cracks, expands, and breaks the rock apart without transporting it.
2.
The wind blows sand to form a sand dune:
Deposition.
* *Explanation*: Wind transports sand and deposits it when it loses energy, forming a dune.
3.
Unique rock shapes that form when wind and/or water cause various particles to hit the rocks which creates unique rock shapes over time:
Erosion.
* *Explanation*: Wind and water carry particles that abrade and wear away the rock surfaces, removing material.
4.
A sinkhole forms when the rock below the ground wears out and then everything about it gives way and caves in:
Erosion.
* *Explanation*: Water dissolves underground rock (chemical erosion), creating cavities that eventually collapse.
5.
Waves dropping sand on the beach:
Deposition.
* *Explanation*: Waves transport sand and deposit it on the shore as they lose energy.
6.
A lot of rain quickly or the rapid melting of snow will cause a landslide:
Erosion.
* *Explanation*: Saturated soil and rock move rapidly downhill due to gravity, which is a form of mass wasting (erosion).
Parent Tip: Review the logic above to help your child master the concept of erosion and deposition worksheet.
