Teton Range and Jackson Hole, Wyoming
(public-domain NPS and NASA images, described in words): Image 1 (NPS aerial photograph of Jenny Lake and Cascade Canyon, Grand Teton National Park): jagged gray peaks rise steeply behind a dark blue lake; a deep notch runs between two of the peaks; flat brown ground lies in front of the lake. Image 2 (NASA Landsat 8 image, June 15, 2015, natural color): a narrow band of high ground with white-capped peaks lies beside a wide, flat valley; dark blue lakes and a winding river lie in the valley; there are no foothills between the peaks and the flat ground. Map (drawn for this question, north at the top): A is the Teton Range, a narrow band running north to south. B is Jackson Hole, a wide valley on the east side of A. C is Jenny Lake, at the foot of A. A side-view sketch beside the map shows the summit of Grand Teton 13,770 ft above sea level and about 7,000 ft above the valley floor. Key: white = snow on the highest ground; dark blue = lakes and river; brown and green = valley floor and forest. Note (NASA): the range rises without foothills. About 10 million years ago the crust began to stretch; the block west of the Teton fault rose to form the range and the block to the east sank to form the valley. NASA also drew a map of elevations, from the ASTER instrument, to show height.
Image 1 shows jagged peaks above a lake, and Image 2 shows high ground beside a flat valley. Which landform fits both clues, Tala asks?
- A mountain range
- A plateau
- A single volcano
- A mesa
Lena River Delta, Russia
(public-domain NPS and NASA images, described in words): Image 1 (NASA Landsat 8 image, July 13, 2021, colors adjusted to show detail in the water): one wide brown river splits into many channels that fan out across flat tundra toward the sea. Image 2 (NASA ASTER image of part of the delta, July 16, 2005): dark channels twist and split around green land dotted with hundreds of small lakes and ponds; light-blue patches are mudflats and shallow water; bright white patches are probably places scoured by spring floods; a scale bar reads 5 km. Map (drawn for this question, north at the top): A is the Lena River, flowing north. B is the delta, where A splits into many channels. C is the Laptev Sea, at the north edge of B. Key: dark blue-gray = water; green = plants; light blue = mudflats and shallow water; white = probably places scoured by spring floods. Note (NASA): the Lena runs about 4,400 km (2,734 mi) north from mountains in south-central Russia. Its delta covers nearly 30,000 km2, about the size of Maryland, and stays frozen for as long as seven months a year.
Both Lena images show one river splitting into many channels near the sea. Which landform fits both clues, Zee asks?
- A bay
- A glacier
- A delta
- A canyon
Great Sand Dunes, Colorado
(public-domain NPS and NASA images, described in words): Image 1 (NPS photograph, Great Sand Dunes National Park): tan and orange dunes with rippled sides rise beside bright green trees in front, with dark mountains and a snow-capped peak behind under a blue sky. Image 2 (NASA Landsat 7 image, October 14, 1999, natural color): a pale, almost white crescent of dunes lies against the foot of a dark mountain range; darker sand held by grass lies to the west; a straight light line along the bottom is a highway. Map (drawn for this question, north at the top): A is the dune field. B is the mountain range, east of A. C is the darker sand field, west of A. Arrows show the wind blowing from west to east across C and A toward B. Key: light gray-white = sand dunes; darker = sand held by grass; dark green and gray = mountain forest and rock. Note (NASA): the tallest dunes rise about 750 ft. Wind blows sand east until the mountains block it. Two ideas explain where the sand came from: a river carried it, or a lake that fills and dries up left it.
Image 1 shows sand hills at a mountain's foot, and the map shows wind from the west. What explains where the sand piles up, Ari asks?
- Rivers carried the sand up the mountain
- Wind blows sand west, away from the mountains
- Glaciers pushed the sand to the mountains
- Wind blows sand east until mountains block it

- About 270 miles

- About 2,500 m
- About 230 m
- About 23 m

Kira's note says, "Grand Teton rises 13,770 ft above Jackson Hole." Which fix is right?
- Leave it: the valley floor is at sea level
- Change "above Jackson Hole" to "above sea level"
- Change "ft" to "miles"

Luz's note says, "The Lena River flows south into the Arctic Ocean." Which fix is right?
- Leave it: the river flows toward the map's bottom
- Change "Arctic Ocean" to "mountains"
- Change "south" to "north"
- Change "river" to "dune"

Milo's note says, "The dunes are banked on the east side of the mountains." Which fix is right?
- Change "east" to "west"
- Change "mountains" to "ocean"
- Change "dunes" to "lakes"
- Leave it: the map puts the dunes east of the range

- They are certainly cities
- They are probably scoured by spring floods

- It is settled: a river carried it
- It is settled: glaciers dropped it
- No one has any idea
- Two ideas exist: a river or a drying lake
