  1. 3. A flat-topped elevated landform with steep sides, often formed by erosion or tectonic activity.
  2. 6. A narrow and deep valley with steep, rocky sides, often carved by a river or glacier.
  3. 8. A landscape characterized by sinkholes, caves, and underground drainage systems formed by the dissolution of soluble rocks such as limestone.
  4. 9. A hot spring that intermittently ejects a column of water and steam into the air, often with great force.
  5. 12. A shallow body of water separated from a larger body of water by barrier islands, reefs, or sandbars.
  6. 14. A steep slope or cliff formed by erosion or faulting, separating two relatively level areas of differing elevations.
  7. 15. A tall, thin spire of rock that protrudes from the bottom of an arid basin or badland, often with a capstone.
  8. 17. A large underground chamber or cavity, often formed by the dissolution of limestone or other soluble rocks.

Down
  1. 1. A large mass of ice that moves slowly over land, carving valleys and shaping the landscape.
  2. 2. A natural underground chamber or passage, often formed by the dissolution of limestone.
  3. 4. A bowl-shaped depression or cavity, often at the summit of a volcano or formed by a meteorite impact.
  4. 5. A mass of rocks, gravel, and sediment carried and deposited by a glacier, forming a ridge or mound.
  5. 7. A flat-topped hill with steep sides, smaller than a mesa and often isolated in a plain or desert region.
  6. 10. A depression or hole in the ground caused by the collapse of a surface layer, often formed in limestone regions.
  7. 11. A fracture or zone of weakness in the Earth's crust along which movement or displacement occurs.
  8. 13. A large landform that rises prominently above its surroundings, often with a peak or summit.
  9. 16. A mound or ridge of sand formed by the wind, typically found in deserts or coastal regions.
