Waterfall Model for School Project

Introduction:

The waterfall is an area where water from the river flows vertically. They represent abrupt interruptions in the flow of the river. Waterfalls are of various sizes big and small.

There is some process that goes behind the formation of waterfalls depending on the rock type. Rivers usually clear off the irregularities through the process of erosion and deposition.

Over long periods of time of flow, the rivers tend to make a steep curve towards its starting point also known as the mouth of the river.

Thus, in this process of the river moving through the rock beds and erosion, it softens its path leading to formation of a waterfall.

Waterfalls are usually considered as the scenic spots on the country side and also known as source of fresh water.

In this video, we show how to make a waterfall for school project out of waste(cardboard, newspaper etc) and it is very easy to create its model.

Materials Used:

1. Cardboard
2. Unused newspaper
3. Hot glue gun
4. Liquid glue
5. Paint brushes and paints
6. Blue colored pattern sheet
7. Scissors
8. Green Colour sheet

You use the resource/tools page section to find the tips where you can buy these materials used at a reasonable cost.

Questions and Answers:

1. What are the different types of waterfalls?

A. There are many types of waterfall all around the world, they are plunge waterfalls, multistep waterfalls, fan waterfalls, cataract waterfalls etc.

This categorization of the waterfalls is based on the type of erosion the riverbed has gone through, size and shape of the waterfall.

2. What are the largest waterfalls in the world?

A. Victoria waterfalls are the largest waterfalls in the world. It is at a height of 1.7 kilometres.

3. How are waterfalls formed?

A. Rivers always flow through different bands of rock and not on a smooth surface.

Thus, in this process, the river flow erodes the soft rock undercutting the hard rock.

This results in the formation of a waterfall. Most of the times waterfall starts at the beginning of the river or mouth of the river.

And this water flows through vertically plunging at the bottom of the waterfall.

Conclusion:

A river usually at its source takes a form V shape, that is called as a valley. Not only the river flow causes erosion of the rocks but also the weathering breaks up on slopes of the valley.

The material eroded thus moves along the flow of the river and causes erosion of the rock bed that is soft.

This creates a waterfall. Soft rock erodes quickly when compared to the hard rock.

Thus, the hard rock remains the same, allowing the broken soft rock to fall through causing different shapes of the waterfall.
