Desertification:
The process of the land degradation in arid , semi - arid , and sub - humid areas because of the factors , human activities , climatic variations .
This process lead to persistent degradation of the dry land and ecosystem because of some variation in climate and man - made activities .
The major cause of Desertification are -
1. Overpopulation
2. Overgrazing
3. Deforestation
4. Unsustainable agriculture techniques
5. Climate change
6. Stripping of land resources .

Answer:
The red lines on this map show us divergent plate boundaries.
Explanation:
The tectonic plates are in constant movement, and this results in interactions between them. At some places the plates collide, at other places slide past each other, and at some move away from each other. The last ones are the places where there is a divergent plate boundary.
The divergent plate boundaries can occur in the ocean or on land. When they occur in the ocean, they form an underwater mountain range, known as a mid-ocean ridge, which is volcanically highly active. An example of this is the mid-Atlantic ocean ridge. When these boundaries occur on land, they form rifts, where the crust starts to crack, a gap opens up, and gradually widens. An example of this is the Great Rift Valley of Africa.
Answer:
The two most important climatic factors for ecosystems are sunlight and water. Sunlight is necessary for plants to grow, and to provide energy to warm the earth's atmosphere. Light intensity controls plant growth. Light duration affects plant flowering and animal/insect habits.
