Question

СРОЧНОО!!Помогите по географии,завтра сдавать, не успеваю делать.Даю 10 баллов Реки-Нил, Конга, Нигер, Замбези. Ответить на вопросы: 1-Что у этих рек общего? 2-в чем различие? 3-почему реки Африки, в основном несут свои воды, в атлантический океан. 5-почему река Нил протекает по пустыне, не пересыхая? 6-почему у озера Чад меняется площадь?

Answer 1

1 - Все эти реки в Африке.
2-Все в падают в Атлантический океан, а Замбези в Индийский. Конго и Замбези текут в зоне влажного климата, Нил и Нигер - в зоне засушливого климата.
3 Основные горные системы Африки находятся на востоке континента. Получается, что в Индийский океан текут только реки с восточных склонов гор на востоке, а со всей остальной территории - в Атлантический.
5 - Мощные истоки Нила в Экваториальной Африке и Эфиопском нагорье. При этом Нил течет по узкой долине, не растекаясь массой протоков по плоской равнине.
6. Озеро Чад - очень мелкое (в пределах 1-2 метров) и лежит в очень плоской впадине. Поэтому изменение уровня воды на 50 см могут дать движение береговой линии на десятки километров, соответственно и изменение площади.

Answer 2

Rivers - Nile, Congo, Niger, Zambezi

The rivers Nile, Congo, Niger, and Zambezi are all located in Africa and are among the longest and most significant rivers on the continent. Let's answer the questions you provided:

1. What do these rivers have in common? - These rivers are all located in Africa. - They are among the longest rivers in Africa. - They play a crucial role in the ecosystems and economies of the regions they flow through.

2. What are the differences between these rivers? - The Nile River is the longest river in Africa and the world, stretching over 6,650 kilometers. It flows through eleven countries, including Egypt, Sudan, and Ethiopia. - The Congo River is the second longest river in Africa, with a length of about 4,700 kilometers. It is the deepest river in the world and flows through the Democratic Republic of the Congo. - The Niger River is the third longest river in Africa, spanning approximately 4,180 kilometers. It flows through several West African countries, including Guinea, Mali, Niger, and Nigeria. - The Zambezi River is the fourth longest river in Africa, with a length of around 2,700 kilometers. It flows through six countries, including Zambia, Angola, and Mozambique. The Zambezi is known for its famous Victoria Falls.

3. Why do African rivers mainly flow into the Atlantic Ocean? - The main reason African rivers, including the Nile, Congo, Niger, and Zambezi, flow into the Atlantic Ocean is due to the continent's topography. The African continent slopes towards the west, creating a natural drainage system that directs the rivers towards the Atlantic Ocean.

4. Why does the Nile River flow through the desert without drying up? - The Nile River flows through the desert without drying up primarily because of its main source, Lake Victoria, which receives abundant rainfall. The river also benefits from other tributaries and groundwater sources along its course, ensuring a consistent flow of water even through arid regions.

5. Why does the size of Lake Chad change? - The size of Lake Chad changes due to a combination of factors, including climate variability, rainfall patterns, and human activities. The lake is located in a region prone to droughts and fluctuations in precipitation. Climate change and increased water usage for irrigation and other purposes have also contributed to the shrinking of the lake over the years.

I hope this helps! Let me know if you have any further questions.
