Quaternary geology (end of the Ice Age): The last glacial period ended approximately how many years ago? Assume the common GK approximation for the end of the Pleistocene and start of the Holocene. Choose the closest correct value.

Given data

• Asked: Approximate time since the end of the last Ice Age.

Concept/Approach
Geologically, the Holocene epoch begins at ~11,700 years before present, marking the end of the last glacial phase of the Pleistocene. In general GK, this is commonly rounded to about 10,000 years ago.

Reasoning
• Scientific boundary: ≈11.7 ka BP.• Approximation widely used in competitive exams: ≈10 ka BP → best matching option.

Common pitfalls
Selecting 20,000 years (near Last Glacial Maximum) rather than the end of the glacial period.

Final Answer
About 10,000 years ago
