Quiz of the Day
Mountain Day
Tuesday, 11 August 2026
Japan celebrates Mountain Day on August 11 — from Everest to Kilimanjaro, explore the geology, culture, and adventure of the world's great peaks
1. What is the highest mountain in the world measured from sea level?
- K2
- Kangchenjunga
- Mount Everest
- Lhotse
Mount Everest reaches 8,848.86 meters (29,031.7 feet) above sea level — a height revised upward slightly in 2020 after a joint Chinese-Nepalese survey. However, if measured from the center of the Earth, Mount Chimborazo in Ecuador actually extends farther due to Earth's equatorial bulge. And the tallest mountain from base to peak is Mauna Kea in Hawaii, most of which is underwater.
2. Who were the first climbers confirmed to reach the summit of Mount Everest?
- Reinhold Messner and Peter Habeler
- Junko Tabei and her Sherpa guide
- George Mallory and Andrew Irvine
- Edmund Hillary and Tenzing Norgay
Edmund Hillary (New Zealand) and Tenzing Norgay Sherpa (Nepal/Tibet) reached the summit on May 29, 1953, becoming the first confirmed climbers to do so. The news was delivered to Queen Elizabeth II just in time for her coronation on June 2, 1953. Hillary reportedly said it was 'a few more whacks of the ice axe' that got them there — characteristically understated.
3. How were the Alps formed?
- The collision of the African and Eurasian tectonic plates
- Glacial erosion during the ice ages
- Volcanic eruptions over millions of years
- The breakup of the supercontinent Pangaea
The Alps formed as the African tectonic plate slowly collided with the Eurasian plate, beginning about 65 million years ago and continuing today. The Alps are still technically growing — but erosion keeps pace with the uplift. The Himalayas were formed by a similar process: the Indian subcontinent colliding with Asia, and they're rising faster because the collision is more recent and active.
4. What is the 'Death Zone' in mountaineering?
- Areas where avalanches most frequently occur
- The steepest sections of major peaks
- Areas beyond 70 degrees latitude
- Altitudes above 8,000 meters where oxygen is too thin to sustain life
Above 8,000 meters (26,247 feet), the air contains only a third of the oxygen available at sea level. The human body cannot acclimatize at these altitudes — cells begin dying faster than they can regenerate. Even with supplemental oxygen, climbers deteriorate rapidly and must summit and descend as quickly as possible. There are 14 peaks above 8,000 meters, all in the Himalayas and Karakoram ranges.
5. What is Japan's most iconic mountain, considered sacred in Japanese culture?
- Mount Hotaka
- Mount Kita
- Mount Aso
- Mount Fuji
Mount Fuji is an active stratovolcano standing 3,776 meters (12,388 feet) tall — Japan's highest peak. It last erupted in 1707 in an event called the Hōei eruption. Fuji is considered sacred in Shinto and Buddhist traditions and has been a UNESCO World Heritage Site since 2013. About 200,000 people climb it annually during the official summer season.
6. What is K2, and why is it considered more dangerous than Everest?
- A training peak in the Karakoram range
- The most remote mountain in the world
- A peak that's never been fully summited
- Second highest peak with a much higher fatality rate per summit attempt
K2 (8,611m) sits on the Pakistan-China border and has a fatality rate of approximately one death for every four summits — compared to roughly one in 14 for Everest. Its extreme technical difficulty and unpredictable weather earned it the nickname 'Savage Mountain.' K2 was not summited in winter until 2021, when a Nepalese team finally conquered what climbers called the 'last great challenge.'
7. Mount Kilimanjaro in Tanzania is notable for what unusual characteristic among the world's tallest mountains?
- It's a freestanding volcano rising directly from the surrounding plains
- It has the most biodiversity zones of any mountain
- It's the only mountain that spans three countries
- It's surrounded entirely by ocean
Kilimanjaro (5,895m) is the highest freestanding mountain in the world — it rises dramatically straight from the East African savanna with no surrounding mountain range. It's technically a dormant stratovolcano. The mountain contains five distinct climate zones from base to summit, from tropical jungle to arctic ice fields. Its glaciers are receding rapidly and may be gone by the mid-21st century.
8. What is the 'Seven Summits' mountaineering challenge?
- Summiting a peak on seven consecutive days
- Reaching the summit of seven 8,000-meter peaks
- Climbing the highest peak on each of the seven continents
- Climbing the seven tallest peaks in Asia
The Seven Summits are: Everest (Asia), Aconcagua (South America), Denali (North America), Kilimanjaro (Africa), Elbrus (Europe), Mount Vinson (Antarctica), and either Carstensz Pyramid or Kosciuszko (Australia/Oceania — there are two versions of the list). The first person to complete all seven was Dick Bass in 1985, with the journey taking him 3 years.
9. What is the technical mountaineering term for the process of sleeping at progressively higher altitudes to adapt to reduced oxygen?
- Pressure cycling
- Acclimatization
- Hypoxic training
- Altitude staging
Acclimatization involves the body increasing red blood cell production and changing breathing patterns to extract more oxygen from thin air. Climbers on 8,000-meter peaks typically spend weeks at progressively higher camps before the summit push. Moving 'climb high, sleep low' — ascending high by day then descending to sleep — is a standard technique to speed acclimatization.
10. The Andes mountain range runs along the western coast of which continent?
- South America
- Africa
- North America
- Asia
The Andes is the world's longest continental mountain range, stretching 7,000 km along South America's entire western coast through seven countries. Aconcagua (6,961m) in Argentina is its highest peak and the highest in both the Southern and Western hemispheres. The Andes were formed by the subduction of the Nazca tectonic plate beneath the South American plate.
11. What famous ancient site is located high in the Andes at approximately 2,430 meters elevation?
- Chan Chan
- Teotihuacan
- Machu Picchu
- Chichen Itza
Machu Picchu, the 15th-century Inca citadel in Peru, sits at 2,430 meters in the Andes. It was built around 1450 CE but abandoned during the Spanish conquest and not rediscovered by the outside world until 1911 when Hiram Bingham III led an expedition there. The precision of its stonework is remarkable — massive stones fit together without mortar, yet remain stable despite frequent earthquakes.
12. What is the Sherpa community's significance to Himalayan mountaineering?
- An ethnic group from Nepal renowned for high-altitude expertise and guiding
- The helicopter rescue service based in Kathmandu
- They are the government officials who issue climbing permits
- A climbing equipment company founded in Nepal
Sherpas are a Tibetan ethnic group who migrated to Nepal's Solukhumbu region. Their genetic adaptations to high altitude — including more efficient oxygen processing and higher hemoglobin concentrations — make them exceptionally suited for mountaineering. Kami Rita Sherpa holds the record for most Everest summits, having reached the top over 29 times.
13. What is 'volcanic winter' and which volcanic mountain event famously caused one in 1815?
- A historical term for cold weather — Mount Pinatubo eruption
- Winter skiing season around volcanoes — Mount Etna eruption
- A glacier system near active volcanoes — Iceland's Eyjafjallajökull
- Global cooling from ash — Mount Tambora eruption in Indonesia
The 1815 Mount Tambora eruption in Indonesia was the largest volcanic eruption in recorded history. It ejected so much ash and sulfur dioxide into the stratosphere that it reflected sunlight worldwide, causing the 'Year Without a Summer' in 1816. Crop failures across Europe and North America led to famine and migration. The cold, gloomy summer also inspired Mary Shelley to write Frankenstein while sheltering indoors.
14. What is the Matterhorn, and why is it architecturally unique among major Alpine peaks?
- A peak famous for year-round ski access
- The tallest Alpine peak with no recorded summits before 1900
- A pyramid-shaped peak formed by glaciers carving four faces simultaneously
- The only Alpine peak that straddles two countries at the summit
The Matterhorn (4,478m) on the Swiss-Italian border is a 'horn' — a pyramid-shaped peak formed when glaciers carve three or more sides of a mountain simultaneously. Its nearly perfect symmetrical pyramid shape has made it one of the most photographed mountains on Earth and inspired the Toblerone chocolate logo. The first ascent in 1865 was followed by tragedy when four of the seven climbers fell to their deaths on the descent.
15. What is 'mountain sickness' (altitude sickness), and at what altitude does it typically begin?
- Sickness from contaminated glacier water above 3,000 meters
- Severe frostbite occurring above 4,000 meters
- Nausea and headache from rapid ascent, beginning around 2,400 meters
- A psychological fear of heights unique to mountaineers
Acute Mountain Sickness (AMS) is caused by the drop in oxygen and air pressure at altitude. Symptoms include headache, nausea, and fatigue and typically begin above 2,400 meters (8,000 feet). In severe cases it progresses to High Altitude Pulmonary or Cerebral Edema — life-threatening conditions. The only definitive treatment is immediate descent to lower altitude.
