What is the highest temperature ever recorded on Earth, and where did it occur? The official record is 56.7°C (134°F) recorded at Greenland Ranch in Death Valley, California, USA on July 10, 1913. Death Valley is a desert basin 86 meters (282 feet) below sea level, which traps heat. For many years, a temperature of 58°C (136.4°F) recorded in El Azizia, Libya (1922) was considered the record, but the World Meteorological Organization disqualified it in 2012 due to errors in measurement (the thermometer was placed over asphalt). Death Valley also holds the record for the hottest monthly temperature (average daily high of 52.9°C / 127.2°F in July 2018). The park's name comes from pioneers who nearly died there in 1849. Summer temperatures regularly exceed 49°C (120°F). The ground temperature can reach 93°C (200°F) – hot enough to fry an egg.

What is the lowest temperature ever recorded on Earth, and where did it occur? The record is -89.2°C (-128.6°F) recorded at the Soviet Union's Vostok Station in Antarctica on July 21, 1983. Vostok Station is located at 3,488 meters (11,444 feet) elevation on the Antarctic Plateau. In 2010, satellite measurements recorded a temperature of -93.2°C (-135.8°F) at a ridge in East Antarctica, but this was not measured by a ground thermometer, so the official record remains Vostok. At -89.2°C, the air is so cold that: (1) You cannot breathe through your nose (ice crystals form immediately), (2) Metal sticks to skin instantly, (3) Diesel fuel freezes solid, (4) Your eyes freeze shut in seconds. The coldest permanently inhabited place is Oymyakon, Russia (-67.7°C / -89.9°F). The Vostok record was set during the polar night (no sun for 4 months).

Which location holds the record for the highest average annual rainfall, receiving over 11,800 mm (464 inches) per year? This village in Meghalaya, India, holds the Guinness World Record for the wettest place on Earth. Its name means "home of clouds" in the Khasi language. The monsoon winds from the Bay of Bengal hit the Khasi Hills and are forced upward, releasing all their moisture. The village receives rain throughout the year, but the monsoon season (June-September) is especially intense. The local people have developed a unique technology: "living bridges" – they train the roots of rubber trees to grow across rivers, creating natural bridges that strengthen over time. The previous record-holder was nearby Cherrapunji (11,777 mm annually). In 1985, this village received 26,000 mm (1,024 inches) – almost 85 feet – of rain in a single year. The village has no paved roads because they would wash away.

Which location is the driest non-polar desert on Earth, with some weather stations having never recorded rainfall? This desert in South America is located between the Pacific Ocean and the Andes Mountains. It is 50 times drier than Death Valley. Some weather stations have never recorded a single drop of rain. The average rainfall is about 1-3 mm (0.04-0.1 inches) per year, and some areas have had no rain for over 400 years (since records began). Despite the extreme dryness, the desert is home to over one million people who survive by collecting fog water (using "fog nets") and from meltwater from the Andes. The desert is so dry that NASA uses it to test Mars rovers. The soil is similar to Martian soil. In 2010, the desert experienced an unusual rain event after 400 dry years, causing a spectacular "flowering desert" as 200 species of flowers bloomed from dormant seeds.

Which location on Earth has the strongest sustained winds, with an average wind speed of 80 km/h (50 mph) year-round? This location in Antarctica is where cold, dense air from the Antarctic Plateau drops off the ice sheet and accelerates down slope due to gravity (katabatic winds). The fastest wind ever recorded at this location was 327 km/h (203 mph) – nearly the strength of a Category 5 hurricane. The winds are so strong that they strip away snow and ice, creating "blue ice" areas. The station is named after a French polar explorer. Scientists have to tie themselves to ropes when walking between buildings. The wind creates a constant roaring sound that can be heard for miles. The station has been continuously occupied since 1956. The wind is so consistent that the station's buildings are designed to be partially buried and streamlined to reduce wind resistance.

Which location experiences the most lightning strikes on Earth, with over 250 lightning strikes per square kilometer per year? This location is a lake in South America where warm, moist air from the Amazon rainforest collides with cold air from the Andes mountains, creating intense thunderstorms almost every night. The lake receives an average of 297 lightning strikes per square kilometer per year – the world's highest density. Storms occur on 140-160 nights per year, starting around 7 PM and lasting until 9 AM. The lightning is so consistent that sailors used it for navigation before GPS. The phenomenon is known as the "Catatumbo lightning" (Relámpago del Catatumbo). The lightning produces 1.2 million strikes annually, and can be seen from 400 km (250 miles) away. The area holds a Guinness World Record for the highest concentration of lightning. The lightning generates significant ozone, which contributed to the area's name (Catatumbo means "house of thunder" in the local language).

Which ocean basin produces the most tropical cyclones (hurricanes/typhoons) annually, with an average of 25-30 storms per year? This ocean basin covers the region from the Philippines to Japan, including the South China Sea. It is the most active tropical cyclone basin on Earth, producing about one-third of the world's annual total. The strongest tropical cyclone ever recorded, Typhoon Tip (1979), occurred here with sustained winds of 305 km/h (190 mph) and a diameter of 2,220 km (1,380 miles) – half the size of the continental United States. The basin's cyclones are called "typhoons" (from the Chinese "tai fung" – big wind). The basin has no "season" – typhoons can occur year-round, but peak season is May-November. Countries most affected include the Philippines, Japan, China, Taiwan, Vietnam, and South Korea. The basin's warm ocean temperatures (above 26.5°C / 80°F) and high humidity fuel the storms.

Where was the largest hailstone ever recorded in the United States (and world record for weight)? This hailstone fell in South Dakota on July 23, 2010. It measured 20.3 cm (8.0 inches) in diameter, 47.6 cm (18.75 inches) in circumference, and weighed 0.88 kg (1.94 pounds). The previous record was a hailstone in Aurora, Nebraska (2003) weighing 0.96 kg (2.11 pounds) – but the Aurora hailstone was damaged before measurement, so the official record remains disputed. The largest hailstone by diameter is 20.8 cm (8.2 inches) in Vivian, South Dakota (2010). Hailstones of this size fall at speeds over 160 km/h (100 mph) and can kill people, destroy roofs, and break through car windshields. The hailstone was preserved in a freezer at the National Center for Atmospheric Research. Hail forms when updrafts in thunderstorms carry water droplets above the freezing level, where they freeze and accumulate layers of ice.

Which country experiences the most tornadoes of any country, averaging over 1,200 per year? This country lies in a region where cold, dry air from Canada meets warm, humid air from the Gulf of Mexico, creating perfect conditions for supercell thunderstorms. The central part of the country is known as "Tornado Alley" (Texas, Oklahoma, Kansas, Nebraska, South Dakota, Iowa, and Missouri). The country has the strongest tornadoes (EF-5, winds over 322 km/h / 200 mph) and the longest-lasting tornadoes (the Tri-State Tornado of 1925 traveled 352 km / 219 miles across 3 states, killing 695 people). The country's tornado season runs from March to July, but tornadoes can occur in any month. The country has a dedicated NOAA Storm Prediction Center that issues tornado watches and warnings. The United Kingdom has the most tornadoes per unit area (about 35 per year, but much weaker), and Bangladesh has the deadliest tornadoes due to high population density.

Which location in Hawaii is famous for having more rainbows per capita than anywhere else on Earth? This location in Hawaii is known as the "Rainbow Capital of the World." Rainbows form when sunlight passes through raindrops at a 42-degree angle. Hawaii has perfect conditions: frequent rain showers (from the trade winds hitting the mountains) combined with bright sunshine (clear skies between showers) and clear air (no pollution to block sunlight). The location averages over 200 rainbows per year – one every 1.8 days. The Hawaiian language has at least 20 words for different types of rainbows. The state's nickname is the "Rainbow State." The University of Hawaii's sports teams are called the "Rainbow Warriors" and "Rainbow Wahine." The location also has the world's largest natural rainbow (visible from the mountains to the sea). Scientists study rainbows here to understand atmospheric optics.
