The Great Rift Valley is known for experiencing a significant amount of tectonic plate shifting. This geological feature is formed by the movement of tectonic plates, which causes the Earth's crust to crack and create a rift. The Great Rift Valley is a prime example of this phenomenon, as it stretches over 6,000 kilometers and is home to numerous active volcanoes and seismic activity. The tectonic plate shifting in this region has led to the formation of stunning landscapes, including deep valleys, high mountains, and large lakes.

Explanation
The Sahel region is gradually becoming more like the Sahara due to problems with drought. The Sahel is a transitional zone between the Sahara desert and the more fertile regions to the south. It experiences periodic droughts, which have been increasing in frequency and severity in recent years. These droughts have led to desertification, causing the Sahel to become more arid and resembling the Sahara desert. This process has significant implications for the local population, as it affects agriculture, water availability, and livelihoods in the region.

Its rich biodiversity and dense forest cover make it a crucial ecosystem for numerous plant and animal species.

Explanation
The Atlantic Ocean is the correct answer because it is known to cover an area of about 82 million square miles. It is the second-largest ocean in the world, stretching between the Americas to the west and Europe and Africa to the east. The Atlantic Ocean is a major body of water that plays a crucial role in global climate patterns and serves as a vital transportation route for trade and commerce.

Explanation
The correct answer is Atlas Mountains because they are a mountain range that extends approximately 1,500 miles.

Explanation
The Sahara Desert is the correct answer because it is the largest hot desert in the world, covering about 25% of the African continent. It spans across several countries in North Africa, including Algeria, Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Sudan, and Tunisia. The Sahara Desert is known for its extreme aridity, with very little rainfall and high temperatures, making it a challenging environment for life to thrive.

Explanation
The Niger River is the correct answer because it is known to be 2,600 miles long. The Niger River is the principal river of western Africa and is the third-longest river in Africa, after the Nile and the Congo.
