Question 1: The Mesquite Flat Sand Dunes are in which national park?

A Death Valley
B White Sands
C Grand Canyon

Death Valley National Park is the largest national park in the contiguous US, located on the California-Nevada border. It is known for being the hottest, driest, and lowest national park, with Badwater Basin marking the lowest point in North America at 282 feet below sea level.

Correct Answer: Death Valley

Question 2: These dunes were named after which plant?

A California poppy
B Mesquite tree
C Lavender

The mesquite trees here have adapted to the dunes’ shifting sands by twisting and growing in unique ways to avoid being buried. Their leafless, brown trunks are often exposed by the moving sands, and they elongate their stems and branches upward as sand accumulates around them.

Correct Answer: Mesquite tree

Question 3: Where is the highest sand dune in the world?

A Kenya
B New Zealand
C Argentina

Duna Federico Kirbus—named after the journalist who discovered its true height—is the highest sand dune in the world, located in northwestern Argentina. It stands at an impressive height of 4,035 feet. This dune is part of a semicircular sand valley called the Bolsón de Fiambalá.
