In 1950, the amount of energy generated by hydroelectric dam and wood was almost the same, making up a little below 2 quadrillion Btu. The production of renewable energy from wood experienced a stagnation in the next 25 years, while the production of energy by hydroelectric dam constantly increased. Hydroelectric dam was the major energy contributor from 1950 until 2000. This is indicated by the similar pattern shown by the amount of energy produced by hydroelectric dam and the total energy consumption. When the production of energy by hydroelectric dam reached its peak, the amount of total energy consumption leaped.
Biodiesel and wind hadn’t been used to generate energy until the year of 1980. Despite their later start, these energy sources witnessed a stable growth until the end of the period. It was even predicted that the amount of energy generated by biodiesel and wind will still increase after the year of 2000.
The pie charts compare boys’ and girls’ participation in cultural and leisure activities. Overall, boys prefer playing basketball and computer games, while girls like dancing and reading.
The first chart indicates that boys spend much of their time playing video games, making up 34% of their participation rate. Basketball is the second highest favourite activity, representing almost one third of the overall participation. Other physical activities like soccer and skateboarding contribute less than 20% participation rate. Both boys and girls enjoy listening music, accounting for 10% participation rate. The chart indicates that boys only spend 2% of their time reading
Turning to the second chart, it is shown that girls are fond of dancing and reading. The participation rate are 27% and 21% respectively. Their interest in playing computer games is 18% lower than boys’. A similar trend is also illustrated by physical activities like netball and gymnastic, whose percentages are slightly lower than other activities.
The map compares
the layout of a city in the year of 1980 and 2005. The city is divided into two regions, one is located in the north of River Alanah and the other region is located in the south.
The city had significantly changed over the period. There used to be an open space near the hospital, but in 2005, it turned into park and stadium. Consequently, the trees in this area had to be cut down. Besides, two parking lots were built near these two new public facilities. As a result, some houses in the eastern part were torn down. There was also a marina built in the south east on the region.
Likewise, the southern region also witnessed some major changes. There was less vegetation in 2005 because the land was occupied by factories, warehouse and skyscrapers. Some public facilities like school, airport and railway station remained unchanged. However, the railway line was extended and now connected the two regions.
The table gives information about several issues faced by students in school A and school B in the year of 2005 and 2015. The number of students who had problems with school is presented in percentage. Overall, school A indicates a positive trend and had fewer troubled students. Meanwhile, school B is showing the opposite trend.
Students in School A used to have serious problem with concentration in lessons and following instructions in which a total of 82 cases were found. Ten years later, the numbers were roughly reduced by a half. The data also indicates that problems with listening skills and verbal expression of ideas experienced 15% and 14% decrease. Problems regarding spelling slightly decrease from 30 to 25 cases. However, problem with handwriting and reading ability remained unsolved.
School B had a lot to improve in terms of students’ progress. After a decade, the percentage of issues related to handwriting and concentration in lessons were yet to be solved. There was 1% increase in problems related to reading ability, listening skills, verbal expression of ideas. Sadly, the number of students having problem with spelling and following instructions were two times higher in 2015.
The diagram illustrates the process of manufacturing bricks. Overall, there are eight stages of producing bricks involving various materials and equipment.
First of all, the clay is collected using a digger. The clay which has been collected is then filtered by using a metal grid. This is done to get clay with the best texture suitable for making bricks. The filtered clay is then put on a metal grid and mixed up with some water and sand. The mixture of these three materials is then processed either by using mould or wire cutter, so that it turns into a brick with rectangular shape. After going through the moulding stage, the bricks are kept in a drying oven for 24 to 48 hours.
Bricks that have been dried are now heated in a kiln. The heating process starts from moderate temperature of 200°C to 980°C. The temperature is raised until it reaches 870°C to 1300°C. The temperature is raised gradually to avoid the bricks being damaged by the heat. After the bricks are heated, they are kept in a cooling chamber for 48 to 72 hours. Now, the bricks are ready for packaging and will be distributed by a delivery truck.
