Graphs- explained simply. What are graphs and examples.

 Graphs are sources of visual representation to display quantities of numerical data.

For example:

John surveyed the class to discover the most popular type of pet. His results were as follows.

Cat- 4

Dog- 12

Bird- 2

Hamster- 6

A. what is the most popular type of pet in John's class?.

B. How many students are in this class?.

C. Display this data.

 Zoning in on query 'C' of this question we are asked to display the data.

To display numerical data we can adjust a graph into the solution/final submission of this question/query. 

However, there is a large quantity of graphs to choose from. Ranging from bar charts to line plots it can be rather complex.

Bar charts

( Bar charts )

Bar charts are a graph consisting of vertical bars and the horizontal and vertical axis. The numerical source of the data ( in this case the quantities of students ) are situated precisely/accurately on the vertical axis, whilst the bars are specifically situated on the horizontal axis.

Please feel free to watch this YouTube video corresponding to the concept of bar charts:

The width of the bars must all be the same. And the space between the bars must be of the same length.

 

 

Find a summary of bar charts here:

Line plots

Line plots are basically a line with accurate placements of bullet points. There are small 'x's above the bullet points to represent the data. The important thing with line plots is to be accurate and precise. Place the bullet points the same length away from each other and make sure your 'x's aren't too far away from each other. 

 Take a lot at some of those videos to get a better idea of the concept of line plots.

Hydroelectric power (HEP)

 Greetings geology studies students 👋. I hear you need some help understanding or grasping the concept of hydroelectric power. Well, you've certainly come to the correct place as I will be explaining the key points and some other vital information about hydroelectric power here at Kayla's Blog!. 

Defenition- simple and complex

Here I have included a simple to understand definition of HEP and a more advanced definition. Choose whichever benefits you the most 😊.

Simple

Hydroelectric power means creating electricity using water.

Advanced

Hydroelectric power is the main renewable energy resource that converts water from rivers into electricity by using the water to turn a wind turbine which generates electricity. 

Key words:

Hydroelectric power

Dam

Wind turbine

impermeable

Hydroelectric power station

Hydroelectric power station requirements: 

A water supply- usually from rivers. You need the water to turn the wind turbine.

A slope- a HEP station needs to be built in an area where there is a drop in the course of the river. This slope/drop will ensure the rapid pace of the river.

Impermeable bedrock- you cannot lose any water. Permeable rock is the rock that water can sink through so you need your rocks if any to be impermeable.

Climate- you need a climate with a lot of rainfall to maintain the water levels. A dry climate would not be beneficial for a hydroelectric power station as the water could evaporate and the levels of the water would be low.

In the works:

So how does this renewable energy resource function?.

You need to have a dam across a river. A dam is a concrete wall that controls the flow of water. What does this dam do?. Well, the dam traps water. When part of the dam opens, water quickly flows through. That water is used to turn a wind turbine which generates electricity. 

Examples of wind turbine stations: 

In China there is the three georges dam.

    In Ireland there is one in County Cork called the Inniscara dam.
