Final answer:
Big Bend National Park got its name due to the large bend that occurs in the Rio Grande river.
Step-by-step explanation:
Big Bend National Park got its name due to the large bend that occurs in the Rio Grande river, which serves as the park's southern boundary. The river makes a drastic U-turn, creating a noticeable bend in the landscape.
This unique geographic feature is what led to the park being named 'Big Bend'. The park is located in the state of Texas and covers a vast area with diverse geological formations that showcase millions of years of deposition.
Some of the main attractions in the park include Santa Elena Canyon, which showcases breathtaking cliffs and canyons, as well as the Chisos Mountains, which stand tall and provide panoramic views of the surrounding area.
