Question

The place of origin of a river is called_________.
A) Source
B) Mouth
C) Both a and b
D) None of these

Answer 1

Hint: It is also known as a headwater. The tributary that began the furthest distance from the end of the river will be called a headwater. Another option means that the point where the river meets the sea.

Complete answer:
The source is called the location where a river starts. A river's place of origin is called the river's source. The beginning of a river is called the young stage or the source, as it flows rapidly with lots of energy. This age is often referred to as the senior age. The river is smaller here and typically has a rapid, tumbling flow that slices through rocky hills or mountains through a narrow channel.

Now let us look into the given options:
Source : Source is the origin of the river from where the young river begins and flows with lots of energy. Thus this is the correct answer.
Mouth : An oval-shaped cavity within the skull is the mouth. Eating and communicating are the two primary functions of the mouth. The lips, vestibule, mouth cavity, gums, teeth, hard and soft palate, tongue, and salivary glands include portions of the mouth. Thus this is the wrong option.
Both a and b : option A is the correct option and option B is wrong thus this option is wrong too.
None of these : option A is the correct option thus this option is wrong too.

Hence the correct answer is option ‘A’.

Note:
Important facts to remember
-The largest estuary in India is at the mouth of the river Godavari, not the Narmada or the Ganga.
-From its estuary or its confluence with another river or stream, the source is the farthest point of the river stream.
-At the highest point in an area, all rivers start. It gains more water from other streams, ponds, springs, added rainfall, and other water sources as the river flows downstream.
