Me with the following, kindly;
1. the number of people who live in a square mile or kilometer
2. people who leave their homelands seeking safety in a foreign country
3. long period of dry weather resulting in water shortages
4. the growing of crops to provide for the needs of one's family
5. what led to the formation of the great rift valley and the great escarpment?
6. africa is known as the continent.
7. also known as the zaire, in central africa is one of the longest rivers in the world. it crosses the equator twice on its way to the atlantic ocean.
8. the longest river in the world. at four thousand miles (6400 km), it is twice as long as the mississippi. this river flows north and drains into the mediterranean sea. fertile soil around the nile makes the surrounding lands good for farming.
9. the third longest river in africa. it is 2600 miles (4180 km) long. its waters are used by farmers and for fishing.
10. the fourth longest river in africa, is the site of one of the world's most impressive waterfalls, victoria falls. this spectacular physical feature is formed when the zambezi's waters drop off into a steep canyon.
11. what makes portions of sub-saharan rivers in-navigable?
12. what ecosystem is most likely to be found closest to the equator?
13. the desert runs through west and central africa. it stretches from the atlantic to the pacific ocean.
14. what is the ituri?
15. what is the inter-tropical convergence zone (itcz)?

1. Population density

2. Refugees

3. Drought

4. Subsistence farming

5. Tectonic plate movement

6. Plateau continent

7. River Congo

8, River Nile

9. River Niger

10. River Zambezi

11. The presence of cataracts and swift rapids

12. The Rain-forest ecosystem

13. The Sahara Desert

14. The world's second largest rain forest ecosystem

15. It is an area of low pressure where the trade winds meet and mostly affects the climate of the region and people's activities.

Explanation:

1. Population density - The number of people who live in a square mile or kilometer

2. Refugees - These are People who leave their homelands, due to many reasons including political instability, seeking safety in a foreign country.

3. Drought -  These are long periods of dry weather resulting in water shortages.

4. Subsistence farming - This refers to the growing of crops to provide for the needs of one's family; domestic consumption.

5. Tectonic plate movement led to the formation of the Great Rift Valley and the Great Escarpment in most parts of the African continent.

6. Africa is known as the Plateau continent. A plateau is also referred to as a table land and is usually an area of fairly level high ground. Most parts in Africa are located on a fairly level high ground.

7. River Congo - Also known as the Zaire, in central Africa is one of the longest rivers in the world. It crosses the equator twice on its way to the Atlantic Ocean.

8. River Nile - The longest river in the world. At four thousand miles (6400 km), it is twice as long as the Mississippi. This river flows north and drains into the Mediterranean Sea. Fertile soil around the Nile makes the surrounding lands good for farming.

9. River Niger - The third longest river in Africa. It is 2600 miles (4180 km) long. Its waters are used by farmers and for fishing.

10. River Zambezi - The fourth longest river in Africa, is the site of one of the world's most impressive waterfalls, Victoria Falls. This spectacular physical feature is formed when the Zambezi's waters drop off into a steep canyon.

11. The presence of cataracts and swift rapids makes portions of Sub-Saharan rivers in-navigable. cataracts and swift rapids make the region's rivers in-navigable in many places.

12. The Rain-forest ecosystem - This is the ecosystem that is most likely to be found in regions closest to the equator.

13. The Sahara Desert runs through West and Central Africa. It stretches from the Atlantic to the Pacific Ocean. Farmers here practice shifting agriculture, moving to a new location when soil nutrients are used up.

14. The Ituri is the world's second largest rain forest.

15. The Inter-tropical Convergence Zone (ITCZ) is an area of low pressure where the trade winds meet, affects the region's climate and people's activities:

polar areas, such as antarctica or the south pole.
