Explanation:
The troposphere is wider at the equator (10mi) than at the poles (5mi). ... Water vapor concentration varies from trace amounts in Polar Regions to nearly 4 percent in the tropics. Most prevalent gases are nitrogen (78 percent) and oxygen (21 percent), with the remaining 1- percent consisting of argon,).
The landform that is not commonly found in an area of karst topography is D. canyon. A canyon is a landform that is a ravine with great depth located between two cliffs or mountain peaks. This is caused by geologic time evolution or erosion over time.
Warm air rises up at the equator and moves toward the poles. Global winds do not move directly from north to south or south to north because the Earth spins.
