Let's answer your questions step by step, using the map and what we know about Cape Cod's glacial history: --- **1. The bulk of the sediment that makes up Cape Cod and the Islands was deposited:** - **Correct answer:** **b. around 14,000 years ago** Cape Cod and the Islands were formed mostly from glacial deposits left at the end of the last Ice Age, about 14,000–16,000 years ago. --- **2. The map above shows the distribution of TWO types of glacial deposits found on Cape Cod.** **a. What type of glacial deposits are found in the blackened areas?** - **Answer:** **Moraine deposits** (unsorted glacial till deposited directly by a glacier, forming ridges). **b. What type of glacial deposits are found in the stippled (shaded) areas?** - **Answer:** **Outwash plain deposits** (sorted sediments deposited by meltwater streams in front of the glacier). --- **3. Which of the above deposits could be classified as till?** - **Answer:** **The moraine deposits** (blackened areas) are made of till, which is unsorted material deposited directly by the glacier. --- **4. Which of the above deposits have been influenced by the depositional effects of running water?** - **Answer:** **The outwash plain deposits** (stippled/shaded areas) have been sorted and deposited by meltwater streams. --- **5. Briefly describe the difference in the TEXTURES of the sediments found in the two deposits.** - **Blackened areas (moraine/till):** **Texture:** Poorly sorted, mix of clay, silt, sand, gravel, and boulders. Angular particles. - **Stippled (shaded) areas (outwash plain):** **Texture:** Well sorted, mostly sand and gravel. Rounded particles due to water transport. --- **6. What features are identified by the letter X on the above map? Explain how these features were formed.** **Feature:** The X marks the **kettle holes** (or kettle lakes). **Step-by-step explanation of formation:** 1. **Retreating Glacier:** As the glacier that covered Cape Cod began to melt and retreat, blocks of ice broke off and became buried in glacial outwash (sand and gravel deposited by meltwater). 2. **Buried Ice Melts:** Over time, these large chunks of ice melted. 3. **Collapse:** As the ice melted, the overlying sediment collapsed into the empty space left behind, forming depressions. 4. **Kettle Holes/Lakes:** These depressions, known as **kettle holes**, sometimes fill with water to become **kettle lakes**. --- **Summary Table:** | Area Type | Deposit Name | Sorting | Particle Size | Formation Agent | |----------------------|---------------|-------------|-----------------|---------------------| | Blackened | Moraine (till)| Poorly | Mixed | Directly by glacier | | Stippled/Shaded | Outwash plain | Well | Sand/Gravel | Meltwater streams | If you need more details or have any other questions, let me know!
