Question 1: We’re visiting Redwood National and State Parks. Where are they?
A California
B Oregon
C Arizona
Redwood National and State Parks protect the world’s tallest trees—some soaring over 370 feet. Established in 1968 and expanded in 1978, the parks safeguard what remains of California’s ancient redwood forests, over 95% of which were logged. These trees store massive amounts of carbon and can sprout new growth from fallen trunks. When a redwood falls, it often gives rise to a ‘fairy ring’—a circle of genetically identical saplings growing from its base. Beyond trees, the parks shelter Roosevelt elk, banana slugs, and tide pools teeming with marine life.
Correct Answer: California
Question 2: Which is the world’s tallest coastal redwood tree?
A Icarus
B Hyperion
C Orion
Hyperion, the tallest known living tree, is a coastal redwood standing at 380 feet. It was discovered in Redwood National Park in 2006, but its exact location remains undisclosed to protect it from damage. Most redwoods live 500–700 years, but some can reach 2,000 years. Hyperion surpasses other towering redwoods like Helios (377 feet) and Icarus (371 feet). Before its discovery, ‘Tall Tree’ in Prairie Creek Redwoods State Park held the record at 367.8 feet. These giants showcase the incredible heights redwoods can reach.
Correct Answer: Hyperion
Question 3: Why do coastal redwood trees depend on fog?
A It cools the forest floor
B It provides moisture they absorb
C It blocks excessive sunlight
Coastal redwoods rely on fog for moisture, especially during dry summers. Their needles absorb water directly from the air through a process called foliar uptake. Fog condenses on the trees, forming droplets that drip to the roots, replenishing groundwater. This provides up to 40% of their annual water intake. The thick canopy helps trap fog, maintaining humidity and reducing water loss. Without fog, redwoods would struggle to survive in California’s summer droughts.
Correct Answer: It provides moisture they absorb
