What is the geographical location and climate of the Nile?

The Nile River Basin spans 35° latitude, and the climate in the north and south is very different, showing obvious latitudinal zonality, and non-zonal factors (mainly topography) also affect the distribution of climate zones to a certain extent.

The Ethiopian Plateau, located in the southeast of the basin, has a vertical spectrum of climate due to the uplift of the terrain, and has the characteristics of distinct dry and wet seasons. In summer, the air over North Africa and the Arabian Peninsula is a low-pressure zone, and the southeast trade winds blowing from the southern Indian Ocean cross the equator and turn to southwesterly winds, merging with the hot and humid airflow from the Gulf of Guinea to form a strong southwesterly airflow, which rises along the windward slope of the plateau, forming a "heavy rain period" in July and September. In winter, dry northeasterly winds from the Southwest Asian continent prevail on the plateau, creating a dry season from October to February.

3 April, Sudan was located at the centre of low pressure and attracted a moist air stream from the Indian Ocean, creating a "light rain period" before the "heavy rain period" over most parts of the plateau. With an average annual rainfall of 1,000,2000 mm, the plateau is the most important rainfall centre in the Nile Basin. The southern part of the basin, the northwestern part of the East African Plateau, is not only affected by the moist air flow from the Gulf of Guinea, but also because it is located in the equatorial lake area, the solar radiation is strong and the convection is strong, so the rainfall is abundant, with an average annual rainfall of 1200 1300 mm, and the seasonal distribution is also relatively uniform

The average monthly rainfall does not exceed a maximum of 180 200 mm and a minimum of 50 60 mm, there is no significant dry season, and the relative humidity is about 70%, which is another rainfall center in the Nile Basin.

From Nemoulay to the north, the rainy season is shortened, the rainfall decreases, and the isorain line is basically zonal. The rainy season occurs in southern Sudan from April to October, while in the central and northern parts of Sudan it is limited to July to August. Annual rainfall in Khartoum is less than 200 mm, while the annual rainfall between Dongura and Cairo is less than 25 mm, and south of Assiut is often rainless all year round.

Due to the influence of the Mediterranean climate, the annual rainfall gradually increases from 25 mm to 200 mm from Cairo to the coast, with most of the rainfall occurring in winter.

The source of the Nile River is the Burundi Plateau in northeastern Africa.

The Nile River Basin is divided into seven regions, the East African Lakes Region, the Highland Mountain River Region, the White Nile Region, the Blue Nile Region, the Atbara River Region, the Nile Region north of Khartoum, and the Nile Delta Region.

The geographical location of the Nile basin is relatively extensive, so it is involved in more than one climate.

The upper Nile region is the East African Plateau, which has a savannah climate.

The birthplace of the Nile, it is located on the equator in the East African plateau and savannah, with a rich climate and water.

The lower reaches of the Nile, on the Mediterranean coast, are affected by the monsoon, with a tropical desert climate in the east, which is hot and dry throughout the year, and a Mediterranean climate in the northwest, with high temperatures and little rain in summer, and mild and rainy winters.

Nile. nile is a river that flows through eastern and northern Africa and flows into the Mediterranean Sea from south to north.

with the Congo River in the Central African region as well as West Africa.

The Niger River region is tied with the three largest river systems in Africa.

At 6,670 km, it is the longest river in the world.

In 2007, some scholars from Brazil claimed that the Amazon River was longer, but it has not yet been universally accepted by the global geography community. The Nile has two main tributaries, the White Nile and the Blue Nile.

The Blue Nile, which originates in the Ethiopian highlands, is the most water and nutrient source of the lower Nile, but the White Nile is the longest of the two tributaries.

The Nile crocodile lives here.

Climate of the basin: savannah climate Tropical desert climate.

The Nile flows through Burundi, Rwanda, Tanzania, Uganda, Ethiopia, Sudan, Egypt, the Sahara Desert, the world's largest desert, and empties into the Mediterranean.

The Nile flows through major topographic areas: the East African Plateau, then the Nile Valley.

The Nile is a river that flows through eastern and northern Africa and flows into the Mediterranean Sea from south to north. Along with the Congo River in Central Africa and the Niger River in West Africa, it is one of the three largest river systems in Africa. At 6,670 km long, the Nile is the longest river in the world.

Question 1: What is the climate type of the upper Nile Hail on the Nile is the East African plateau, which belongs to the savannah climate.

The Nile River originates in the East African plateau on the equator, in a savannah climate zone with abundant water. The Nile River is characterized by regular flooding, usually starting in May in northern Sudan, reaching its highest level in August, and gradually declining thereafter, with low levels from January to May. Although flooding occurs regularly, the amount of water and the timing of high tides vary greatly.

The original cause of this phenomenon is the Blue Nile and Atbara rivers, which are fed by seasonal torrential rains on the Ethiopian highlands. More than 80% of the Nile's water is supplied by the Ethiopian highlands, with the rest coming from the East African highland lakes. When the flood comes, it will inundate the farmland on both banks, and when the flood water recedes, it will leave a thick layer of silt, forming fertile soil.

Four or five thousand years ago, the Egyptians knew how to grasp the laws of the flood and use the fertile land on both sides. For a long time, the Nile valley has been a place of cotton fields and fragrant rice flowers. Sandwiched between the Sahara Desert and the ** Desert, the meandering Nile River is like a green walk, full of infinite vitality.

Question 2: What are the climate zones of the upper and lower reaches of the Nile? To say separately: What is upstream? What is downstream? Savannah climate in the upper reaches of the Nile.

Lower tropical desert climate.

Question 3: What is the climatic zone where the source of the Nile is located The source of the Nile belongs to the savannah climate zone.

It is a unique climate – a tropical desert climate.

It stands to reason that tropical desert climates are the least suitable for the continuation of life, and do not provide the water necessary for the continuation of life, and this seems to be the case.

The flow of the Nile upstream is huge, but there is a lot of evaporation and infiltration along the way, especially the White Nile, one of the Nile's tributaries, which evaporates so badly that there is not much water left to flow downstream.

But while God closed a door, he also opened a window into the ancient Egyptian civilization on the banks of the Nile. Because of this climate, most of Egypt can be grown almost all year round, and crops can reach double or even triple crops a year.

Moreover, because of this arid climate, the Nile River does not flood, and the aforementioned flat landscape of Egypt. Therefore, during the flood season, the flood spreads across the vast land, and everywhere it goes, it is a source of life, providing a good foundation for planting a large number of crops.

The upper reaches have a savannah climate, the middle reaches have a tropical desert climate that gives birth to the Nile, the estuary area has a Mediterranean climate, and the overall climate of the Nile River is characterized by high temperature and little rainfall. And usually there are two distinct seasons of dry and rainy.

【Answer】c

Answer analysis] test question analysis: This question examines students' understanding of the Egyptian civilization in the four ancient civilizations, according to the knowledge learned, the formation of these four civilizations has the same geographical factors, all of them are located in the river valley zone, the terrain is flat, the soil is fertile, and the climate is suitable for human life, the Yellow River Basin of China, ancient Egypt is located in the Nile River Basin, the Nile River Basin created the Egyptian civilization, ancient Babylon belongs to the two river basins, and ancient India belongs to the Indus River basin, therefore, rivers play an important role in the formation of these civilizations, this question chooses c.

Test point: The formation of the four ancient civilizations.

Comments: This question is less difficult, to test students' ability to recognize and remember historical knowledge points, there are two factors in the formation of human civilization, one is the great river civilization, China, Egypt, India, ancient Babylon is the representative, the other is the maritime civilization, ancient Greece and ancient Rome are the representatives, students should pay attention to the difference between the two.

The upper Nile region is the East African plateau, which belongs to the savannah climate and should be a savannah climate.

Savannah climate Tropical desert climate.

Mainly** are seasonal rainstorms.

The Nile River, which flows through eastern and northern Africa, is the longest river in the world, with a length of 6,695 kilometers, and its basin area is second only to the Amazon River in South America, and the Congo River in Central Africa is the two largest river systems in Africa. In Khartoum, the capital of Sudan, the White Nile from Lake Victoria in the mountains of Uganda and the Blue Nile from Ethiopia meet to form the Nile. The Nile River flows north from the capital of Sudan through Sudan and Egypt and into the Mediterranean Sea.

For thousands of years, the Nile River has been flooding regularly every year from June to October. In August, when the river was at its highest, it flooded large fields on both sides of the embankment, and people moved to higher places. After October, the flood waters subsided, and the soil of the original fields was covered with a thick layer of silt.

On these fertile soils, people cultivated crops such as cotton, wheat, rice, dates, etc. The Nile feeds the people living along it, and the desert area forms a green corridor. The ancient Egyptians created a high level of civilization here.

Today, more than 90% of Egypt's population is located in the Nile Coastal Plain and Delta region. It has been said: Egypt is a gift from the Nile.

The capital, Cairo, is at the tip of the Nile Delta, with a population of 15 million (1998), making it the most populous city in the country. Alexandria is an important port in Egypt on the Mediterranean Sea and the largest port in Africa. In the 70s of the 20th century, Egypt built a 110-meter Yasven Dam in Asven, and a huge reservoir appeared on the dam - Nasser Reservoir, which has benefited from power generation, flood control, irrigation, fish farming, shipping, tourism and so on.

Although the dam prevented flooding downstream, the sediment carried downstream by the Nile and into the sea was greatly reduced, and the coastline of the Nile Delta was constantly retreating due to wave erosion. Egypt ** has taken measures to prevent the delta from being swallowed up by the Mediterranean. For a long time, the length of the Nile was estimated at 6

695 kilometres, originating in Lake Victoria, but on 2 April 2006, an expedition of British-New Zealanders announced that they had traced their origins from Lake Victoria and finally found a source in Uganda, an increase of more than 100 kilometres in length. The Nile near Asven, Egypt.

The other source of the Nile is in the Ethiopian highlands at an altitude of 2,000 meters. It's called the Blue Nile. The Nile River is 680 kilometers long.

The Blue Nile River originates from the alpine plateau climate, the White Nile River originates from the savannah climate, the White Nile and the Blue Nile River regularly flood from June to October, and the main time for this phenomenon is in summer, when the equatorial low pressure zone moves northward, and the White Nile River is controlled by the tropical low pressure zone, with abundant precipitation and large runoff; However, the headwaters of the Blue Nile River are affected by the increase of temperature, the increase of ice and snow meltwater, the increase of runoff, and the merging of the two rivers to form flood peaks, so that the formation of regular flooding.

The main types of climate in the Nile Basin are (savannah) and tropical desert.

The main types of climate in the Nile basin are savannah climate and tropical desert climate, with a small Mediterranean climate on the northern Mediterranean coast.

Tropical desert and savannah climate.
