My son has to Compare and Contrast a normal fault and a reverse fault. Can you tell me if there is something he has left out in his answer? After reading in his science book this is what he wrote---- In comparing and contrasting a normal fault and a reverse fault it is known that tension forces cause normal faults and compression forces cause reverse faults.They both have the same structure but the blocks move in the opposite direction. In a normal fault the hanging wall slips down below the footwall,but in a reverse fault the hanging wall slides up and over the footwall.
Is there any important factors he is missing???
science math social studies
no i don't believe anything!!!
I just taught my class that
If i was is his teacher i would give hime an A bc there really is not anything else he could add to it!!
just tell him to reread the section and put alittle bit more details but don't over detail it!!!
Your son has provided a good comparison between a normal fault and a reverse fault. However, there are a few additional important factors that can be considered when comparing and contrasting these two types of faults.
1. Stress Types: Your son mentioned that tension forces cause normal faults and compression forces cause reverse faults, which is correct. However, it would be beneficial to explain further that tension forces pull rocks apart, leading to the formation of a normal fault, whereas compression forces push rocks together, causing a reverse fault.
2. Strain Direction: In a normal fault, the hanging wall (the block above the fault) moves down relative to the footwall (the block below the fault). On the other hand, in a reverse fault, the hanging wall moves up over the footwall. It might be helpful for your son to include this information in his answer.
3. Plate Boundary Context: Normal faults are commonly associated with divergent plate boundaries, where two plates move away from each other. On the other hand, reverse faults are often found at convergent plate boundaries, where two plates collide or compress against each other. It could be useful to mention this context in the comparison.
4. Associated Geologic Features: Normal faults often give rise to features such as horsts, which are uplifted blocks of land between two parallel normal faults, and grabens, which are down-dropped blocks of land between two parallel normal faults. Reverse faults can create folds, such as anticlines and synclines, which are bends or waves in rock layers.
By including these additional factors in the comparison, your son will provide a more comprehensive understanding of the differences between normal faults and reverse faults.
