Melting snow from the rocky Mountains
The correct is - (b) the African plate is spreading apart to form two separate plates.
The African tectonic plate, on of the biggest ones, but it will not be like for a long time in the future as the plate is separating into two parts. The eastern part of the plate is moving towards east, and it is moving away from the mainland Africa. Because of this movement, cracks have been forming all over the eastern side of Africa, thus the numerous faults. Over time, as the distance is increasing, the space in between will fill with ocean water, thus making a natural barrier between them, as well as setting the foundations for the creation of a new sea, or maybe even an ocean.
Answer:
governments having limited the incentive for increase by keeping prices low
Explanation:
The Horn of Africa and the Sahel a re regions dominated by arid and semi-arid climate types. This makes these regions very limited when it comes to agricultural production. The climate is not suitable in most of these regions for large scale production, so lot of modifications and investments are needed in order to transform the land. Big problem is also the infrastructure, as it is relatively bad condition, so even what is produced is usually consumed locally because the products can reach the markets in saleable condition. The population growth is quicker than the agricultural growth, so there's a very big problem with malnutrition. The governments are putting lot of effort in this sector, but they are very limited financially, so it is going very slowly.
