Answer:
reforestation
Explanation:
In the past decade, multiple African nations have been working together on projects that have the purpose to stop and reverse the land degradation. For this purpose, the people that live in the areas where the soil has been badly damaged or has been affected by the process of desertification have been mobilized, educated, and motivated to perform a reforestation. The reforestation generally has been taking place along the northern border of the region where it touches the outskirts of the Sahara Desert. The results have been excellent. The trees that have been planted are trees that produce fruits, thus food, they contributed to making the soil more fertile but also much more resilient to erosion, and the wells have started to replenish their water because of the protection from the trees above them that significantly reduce the evaporation.
Each degree is equal to 4 min so 50° means 50×4=200 min
so time is3:20

Mineral of volcanic origin with large crystals is formed by magma that cooled off deeper into the crust.
Explanation:
The rocks of volcanic origin are divided into two main categories by the place of formation, extrusive igneous rocks and intrusive igneous rocks. The extrusive igneous rocks are the ones that form on the surface or near the surface. The intrusive igneous rocks are the ones that form deeper into the crust.
The intrusive igneous rocks are formed by magma that has managed to penetrate the crust, but didn't managed to come to the surface. It started to cool off slowly over longer period of time, thus solidifying. Because the solidifying has been very slow, the minerals formed in this manner have big minerals, as they had time to grow.
Minerals of this type are:
- granite
- diorite
- peridotite
- gabro
