Question 1: What is the approximate elevation of Mont Blanc, the highest peak in the Alps?
- 4,807 meters
- 6,807 meters
- 5,807 meters
- 3,807 meters
Answer: A. 4,807 meters
Explanation: Mont Blanc is the highest peak in the Alps, reaching an elevation of approximately 4,807 meters above sea level, making it a prominent landmark in the European mountain range.
Question 2: Which term describes an amphitheater-like basin formed by glacial erosion at the head of a valley?
- Moraine
- Nunatak
- Cirque
- Arête
Answer: C. Cirque
Explanation: A cirque is an amphitheater-like basin with steep walls, formed by glacial erosion at the head of a glacial valley, often serving as the starting point for mountain glaciers.
Question 3: What is a sharp, narrow, serrated ridge of rock separating two glacial valleys called?
- Arête
- Horn
- Tarn
- Col
Answer: A. Arête
Explanation: An arête is a sharp, narrow, serrated ridge of rock that separates two adjacent glacial valleys or cirques, created by the erosive action of glaciers on both sides of the ridge.
Question 4: Which feature is a steep, pyramid-shaped peak formed by the erosion of three or more cirques?
- Nunatak
- Glacial horn
- Col
- Moraine
Answer: B. Glacial horn
Explanation: A glacial horn is a steep, pyramid-shaped mountain peak formed when three or more cirques erode a summit from different sides, leaving behind a sharp, pointed mountain top.
Question 5: What is the lowest point on a mountain ridge between two peaks, often used as a pass?
- Cirque
- Tarn
- Col
- Arête
Answer: C. Col
Explanation: A col is the lowest point on a mountain ridge between two peaks, often serving as a natural mountain pass for travelers and climbers navigating through the rugged terrain.
Question 6: What is an isolated mountain peak projecting above a surrounding glacier called?
- Cirque
- Moraine
- Nunatak
- Horn
Answer: C. Nunatak
Explanation: A nunatak is an isolated mountain peak or rocky outcrop that projects above the surface of a surrounding glacier or ice sheet, remaining exposed even during periods of heavy glaciation.
Question 7: What is the characteristic cross-sectional shape of a glacial valley in the Alps?
- Flat-bottomed
- W-shaped
- U-shaped
- V-shaped
Answer: C. U-shaped
Explanation: Glacial valleys in the Alps are typically characterized by a broad, U-shaped cross-section created by the immense erosive power of moving ice as it carves through the mountain landscape.
Question 8: What are the ridges of unsorted rock and sediment deposited by a glacier called?
- Tarns
- Cols
- Moraines
- Nunataks
Answer: C. Moraines
Explanation: Moraines are ridges or accumulations of unsorted glacial till, such as rock and sediment, deposited by a glacier as it moves or retreats across the landscape over long periods.
Question 9: Which two tectonic plates collided to form the Alps over millions of years?
- South American and Nazca
- Pacific and North American
- Indian and Eurasian
- African and Eurasian
Answer: D. African and Eurasian
Explanation: The Alps were formed over millions of years as the African and Eurasian tectonic plates collided, causing sedimentary rocks to fold and thrust upward into the massive mountain range.
Question 10: What is a small mountain lake that forms in the floor of a cirque called?
- Tarn
- Moraine
- Col
- Nunatak
Answer: A. Tarn
Explanation: A tarn is a small mountain lake that often forms in the bowl-shaped floor of a cirque after a glacier has retreated, leaving behind a depression that fills with water.
