Question 1

What is the first stage of a river's lifecycle?

Accepted Answer

The first stage is called the source or the beginning of the river. This is where the river starts, often in the mountains where snow melts or from springs.

Question 2

How does water in a river flow?

Accepted Answer

Water in a river flows from higher ground to lower ground due to gravity. It usually moves in a winding path, going around rocks and other barriers.

Question 3

Why do rivers make bends or curves?

Accepted Answer

Rivers bend or curve because they flow around obstacles like rocks and dirt. Over time, water slowly wears away the banks, making those bends bigger.

Question 4

What is the middle stage of a river called?

Accepted Answer

The middle stage of a river is called the mature stage. Here, the river is wider and slower than at its source, and it might have many meanders or curves.

Question 5

What are meanders in a river?

Accepted Answer

Meanders are the big loops or curves in a river. They form because the water travels faster on the outside of the bend and slower on the inside, wearing away the land.

Question 6

What is an oxbow lake?

Accepted Answer

An oxbow lake is formed when a meander is cut off from the main river. It looks like a big, curved pond near the river.

Question 7

What happens in the last stage of a river?

Accepted Answer

In the last stage, known as the old age stage, the river slows down and spreads out. It may form a delta, where it deposits dirt and rocks, creating new land.

Question 8

What is a delta?

Accepted Answer

A delta is the landform created at the end of the river when it deposits silt and dirt. It looks like a fan or triangle where the river meets the sea or a lake.

Question 9

Why does a river carry rocks and dirt?

Accepted Answer

A river carries rocks and dirt because moving water has the power to pick up and push tiny bits of soil and sand. As the river flows, it carries these bits along with it.

Question 10

How does the river's speed change in its lifecycle?

Accepted Answer

A river usually starts fast and narrow in the mountains, then it slows down in the flat areas. By the time it reaches its end, it's slow and wide.

Question 11

What are tributaries?

Accepted Answer

Tributaries are smaller rivers or streams that join the main river. They bring more water, making the main river larger.

Question 12

Why do rivers sometimes flood?

Accepted Answer

Rivers flood when there is too much rain and the river can't hold all the water. The extra water spills over the banks onto the land.

Question 13

Do rivers always flow north to south?

Accepted Answer

No, rivers can flow in any direction depending on the shape of the land. They flow downhill, which can be north, south, east, or west.

Question 14

Can rivers change their path?

Accepted Answer

Yes, rivers can change their path over time. This happens because of erosion, where the river wears away the land and creates new channels.

Question 15

Why is the water in a river sometimes brown or muddy?

Accepted Answer

The water looks brown or muddy because it carries a lot of tiny particles of dirt. These particles are picked up from the riverbed and banks.

Question 16

What are riverbanks?

Accepted Answer

Riverbanks are the sides of the river. They hold the water in and are often covered with plants, which help stop the banks from washing away.

Question 17

What kind of plants and animals live in rivers?

Accepted Answer

A variety of plants like reeds and water lilies grow in rivers, and animals like fish, frogs, and turtles live there too. Some birds and insects also depend on rivers for food.

Question 18

Why are rivers important?

Accepted Answer

Rivers are important because they provide water for drinking, farming, and help plants and animals live. People also use them for transportation and generating electricity.

Question 19

What do people use rivers for?

Accepted Answer

People use rivers for many things like swimming, transportation, and fishing. Rivers are also used to water crops and produce electricity through dams.

Question 20

How can we keep rivers healthy?

Accepted Answer

We can keep rivers healthy by not throwing trash in them and by cleaning up pollution. It's also important to plant trees and bushes along riverbanks to prevent erosion.
