3. Рака - гэта стужкападобны вадаём, які цячэ ўніз ад сілы
прыцягнення. Рака можа быць шырокай і глыбокай або
досыць дробнай, каб чалавек мог перабрацца ўброд.
Праточны вадаём, меншы за раку, называецца ручаём,
ручаём або ручаём.
Некаторыя рэкі цякуць круглы год, а іншыя цякуць толькі ў
пэўны сезон або калі было шмат дажджоў. Даўжыня самых
вялікіх рэк можа дасягаць тысячы кіламетраў. Эрозійная сіла
рэк можа ўтвараць геалагічныя цуды, такія як Гранд-Каньён.

4. In this Video, we have provided the list of
the Top 5 longest rivers of the world
along with their length and country of
origin.

5. There are a couple of key factors to consider when
trying to identify the longest river in the world, namely:
• The source (where the river starts)
• The location of the river mouth (where the river ejects,
effectively where the river end and the
sea/ocean/estuary begins)

6. The Nile river is considered to be the longest river in the
world. Lake Victoria is considered to be the source of the
river. It flow through the Egypt, Uganda, Ethiopia, Kenya,
Tanzania, Rwanda, the Democratic Republic of the Congo,
Eritrea, Burundi, Sudan, and South Sudan.
Блакітны і Белы Ніл - два прытокі ракі. Хаця для
большасці з нас рака Ніл з'яўляецца самай доўгай ракой
у свеце

8. The Amazon River is undoubtedly the largest river in the
world by discharge volume of water. However, its position as
the second-longest river in the world is highly disputed as the
title has for long been granted to the Nile River in Egypt.
The dispute arises from the determination of the origin of the
Amazon. A recent 2014 study claims that the origin of the
Amazon can be traced to the Cordillera Rumi Cruz.

10. The Yangtze River is the world's third longest river and the longest to
flow entirely within one country. It is also the longest river in Asia. The
river basin of the Yangtze houses one-third of the population of the
most populated country in the world i.e., China. Traditionally, the
government of China recognizes the Tuotuo tributary located in the
Tanggula Mountains as the source of the river.
According to new data, however, the source of the Yangtze River is located
in the Jari Hill from where the headwaters of the Dam Qu tributary
originate.

12. The river system comprising of the Mississippi, Missouri, and
Jefferson rivers, is regarded as the world's fourth longest river
system. The river system drains 31 US states and 2 Canadian
provinces. The Mississippi River begins in northern Minnesota
where Lake Itasca is believed to be the source of the river and
drains into the Gulf of Mexico.
However, when we regarded the Jefferson River as the furthest source
of the Mississippi River, then we get the Mississippi–Missouri–
Jefferson river system.

14. This is the world's fifth-longest river system and the largest
draining into the Arctic Ocean. The Selenge River is regarded as the
headwaters of this river system. The Selenge River is 992 km long
and drains into Lake Baikal.
The Angara river rises from Lake Baikal near Listvyanka and flows
through the Irkutsk Oblast of Russia and finally joins the Yenisei River
near Strelka. The Yenisei finally drains into the Arctic Ocean. The total
length covered is 5,539 miles.
