Answer: Carbon dioxide (CO₂). Plants use CO₂, water, and sunlight to produce glucose and release oxygen as a byproduct through the process of photosynthesis.
Answer: A quaking aspen grove named Pando in Utah, USA. This clonal colony shares a single root system and is estimated to weigh over 6,600 tons, covering 106 acres.
Answer: The Venus flytrap (Dionaea muscipula). Native to the wetlands of North and South Carolina, it traps prey using modified leaves that snap shut when trigger hairs are touched.
Answer: Transpiration. This process helps plants draw water up from the roots, cools the plant, and facilitates the movement of minerals through the plant's tissues.
Answer: The cherry blossom tree (Prunus serrulata). Known as "sakura" in Japanese, cherry blossom viewing festivals called "hanami" have been celebrated in Japan for centuries.
Answer: Chlorophyll. This pigment absorbs red and blue light while reflecting green light, which is why most leaves appear green to the human eye.
Answer: The vanilla orchid (Vanilla planifolia). It is the only orchid species widely cultivated for food, and each flower must be hand-pollinated to produce the vanilla bean.
Answer: The coco de mer seed from the Seychelles. These seeds can weigh up to 30 kg (66 lbs) and take 6–10 years to develop on the female tree.
Answer: The bristlecone pine (Pinus longaeva). A specimen named Methuselah in California's White Mountains is over 4,800 years old, making it the oldest known individual tree.
Answer: Bamboo. Some species can grow up to 91 cm (35 inches) per day under optimal conditions, thanks to their unique rhizome root system.
Answer: The corpse flower (Amorphophallus titanum). Its bloom can reach over 3 meters (10 feet) in height, and the smell attracts carrion-feeding insects that help pollinate it.

Answer: The Serengeti–Mara ecosystem. Each year, wildebeest, zebras, and gazelles migrate in a circular pattern between Tanzania's Serengeti and Kenya's Maasai Mara.
Answer: The polar ice biome (polar desert). Found in Antarctica and the Arctic, temperatures can drop below −60°C (−76°F) and precipitation is extremely low.
Answer: Biodiversity. It includes genetic diversity within species, species diversity within ecosystems, and ecosystem diversity across landscapes.
Hurricanes, tornadoes, climate change, and seasons — 10 questions
Answer: The Saffir-Simpson Hurricane Wind Scale. It rates hurricanes from Category 1 (minimal damage) to Category 5 (catastrophic damage) based on sustained wind speeds.
Answer: A tornado. The United States experiences more tornadoes than any other country, with over 1,000 reported annually in "Tornado Alley."
Answer: Carbon dioxide (CO₂). While water vapor contributes significantly, CO₂ is the primary long-lived greenhouse gas driving anthropogenic climate change.
Answer: The tilt of Earth's axis (approximately 23.5 degrees) as it orbits the Sun. This tilt causes different parts of Earth to receive varying amounts of solar radiation throughout the year.
Answer: The Atacama Desert in Chile. Some areas have experienced no significant rainfall for centuries, making it one of the most Mars-like environments on Earth.
Answer: El Niño. This climate pattern disrupts weather worldwide, causing droughts in some regions and heavy rainfall in others, and typically occurs every 2–7 years.
Answer: A barometer. Changes in atmospheric pressure help meteorologists predict short-term weather changes.
Answer: Cumulonimbus clouds. These towering clouds can reach heights of over 12 km and are associated with lightning, thunder, heavy rain, and sometimes hail or tornadoes.
Answer: A weather front. When warm and cold air masses meet, the resulting conditions can produce storms, precipitation, and significant temperature changes.
Answer: Approximately 1.1°C (2°F) above pre-industrial levels. The majority of this warming has occurred since 1975, driven primarily by human activities.
Grand Canyon, Northern Lights, Victoria Falls, and more — 10 questions
Answer: The aurora (Northern Lights / aurora borealis in the northern hemisphere). These dazzling light displays are typically visible near the magnetic poles.
Answer: The Grand Canyon. Carved by the Colorado River over millions of years, it is 446 km long, up to 29 km wide, and over 1,800 meters deep.
Answer: Angel Falls in Venezuela. Dropping 3,212 feet (979 meters) from Auyán-tepui in Canaima National Park, it is named after American aviator Jimmie Angel.
Answer: Victoria Falls. Located on the Zambezi River between Zambia and Zimbabwe, it is one of the largest curtain waterfalls in the world at over 1.7 km wide.
