The steppe grassland region south of the Sahara desert that is slowly disappearing

• A. Savanna
• B. Steppe
• C. Gobi
• D. Sahel

Answer: (D)

The steady climate belt just south of the Sahara that is turning semi-arid and losing land to desertification is the Sahel. This region acts as a transitional zone between the desert to the north and the greener savannas to the south, with grassland and scrub adapted to low rainfall. Over time, variations in rainfall, droughts, and human pressures like overgrazing and deforestation are causing vegetation to thin and soils to degrade, so the area is slowly shrinking. The other terms don’t fit as well. A savanna is a wetter tropical grassland with more trees, found farther south and with more rainfall. A steppe is a dry grassland term usually used for Eurasian regions. The Gobi is a desert in Asia. So the described region matches the Sahel.
