Band 9 Process Diagram Answer Sample 6


You should spend about 20 minutes on this task.

The diagram below shows how geothermal energy is used to produce electricity.

Summarize the information by selecting and reporting the main features, and make comparisons where relevant.

Write at least 150 words.

The diagram shows that there are five main stages in the production of electricity through the use of geothermal energy.

The process begins with cold water being pumped from the surface of the earth down into a

4.5 kilometer-deep injection well. From there, it is transferred to the geothermal zone, a subterranean region composed of hot rocks, before reaching the production well, which is a vertical pipe similar to the injection well but a bit wider.

In the stage that follows, the hot water is pumped up through the production well into a condenser on the surface where it is converted into steam, following which it is used to power a turbine and rotate it. This turbine is connected to an electricity generator which, when rotated by the turbine, produces electricity. The process ends when the electricity generated by the generator is transferred to the power grid for consumption by end users.

The diagram below shows the process by which bricks are manufactured for the building industry.


Summarize the information by selecting and reporting the main features, and make comparisons where relevant.

Write at least 150 words.

The picture illustrates the procedure for producing construction bricks from clay, sand and water through ten rather simple stages.

It commences when raw clay is dug using a digger machine following which it is sifted through a metal grid into finer fragments which then fall onto a conveyor belt. In the next stage, water and sand are added and the resulting mixture is either pushed through a frame and cut into simple bricks, or is moulded into specially-formed bricks.

These are then placed in a special oven for one or two days in order to minimise their moisture content. The following three stages involve the use of a couple of kilns and a cooling chamber: bricks are first heated moderately in the first kiln to reach a temperature of between 200 and 980 degrees centigrade before being subjected to higher temperatures (870 to 1300 degrees) in the second one.

Next, they are allowed to cool down for two to three days in the cooling chamber. The process ends with the bricks being packed on pallets and delivered to end users on trucks.

The diagram below shows the life cycle of the honey bee.


Summarize the information by selecting and reporting the main features, and make comparisons where relevant.

Write at least 150 words.

The chart illustrates the stages in the life of honey bees. Overall, this life cycle is comprised of six stages, from eggs to fully mature bees, which take approximately five weeks to complete.

The first stage is when the female bee lays up to 2 oval eggs once every 72 hours. These eggs hatch between nine and ten days later, and immature bees, called nymphs, emerge, lacking the typical bee stripes.

Over the next 3 weeks, the nymphs experience three moulting stages, that is, they shed their skins to allow further growth to occur: The first moulting happening 5 days after the eggs hatch, a week after which the second one takes place.

Nine days later, the nymphs moult for a third time, becoming young adult honey bees which are characterised by their striped backs. These take four more days to mature into larger adult bees whose backs are marked with bolder and darker stripes, and the cycle starts over again.

The diagram below shows the process of using water to produce electricity.


Summarize the information by selecting and reporting the main features, and make comparisons where relevant.

Write at least 150 words.

The diagram shows the process through which water is used to produce electrical power. Overall, hydroelectric power is generated using water from the sea through a relatively sophisticated procedure which comprises over ten stages.

The process begins when seawater is heated by the sun and evaporates to form small clouds in the sky. Next, they merge into a storm cloud, which then rains over the mountain. This rainwater is gathered in the reservoir behind a dam. The following steps involve a pipe which connects the reservoir to a turbine as well as a pump, and is controlled using a valve.

Once this valve is opened, water flows into the turbine and rotates it to produce electrical current, following which it is pumped back into the reservoir. After this, the electricity produced by the turbine is transferred to the transformer station through high voltage cables. The last stage is when the electrical power is delivered to domestic and industrial consumers, as well as educational and medical facilities.

The graph shows how coal is used for electricity production.
Summarize the information by selecting and reporting the main features, and make comparisons where relevant.

Write at least 150 words.

The diagram shows the various stages in the production of clean energy from coal.

First of all, the coal is mined in deep pits underground and then carried to the surface. After that, it is carried along a conveyor belt to a power plant where it is burned in a large furnace to which oxygen is added to produce raw syngas.

At the next stage of the process harmful substances such as carbon dioxide, mercury, and sulfur are removed. Following that, the purified gas is used to drive a gas turbine. The turbine in turn powers a generator, producing electricity. The gas turbine also produces hot exhaust gases. These are piped to a heat recovery steam generator, which converts the heat into steam. The steam is subsequently used to power a steam turbine, which again is used to generate electricity.

The energy is clean because the harmful products are removed and the coal is not transported to another site to produce electricity.

The diagrams below show the stages and equipment used in the cement-making process, and how cement is used to produce concrete for building purposes.


Summarize the information by selecting and reporting the main features, and make comparisons where relevant.

Write at least 150 words.

The diagrams show how cement and concrete are produced. Overall, there are five stages in the production of cement, while the procedure for producing concrete from cement and a few other simple ingredients involves a single stage.

Cement production begins when the initial raw materials, namely limestone and clay, are crushed using two rotating drums to make a fine powder which is then mixed in a cylindrical mixer. The next stage involves a tube-like rotating heater with a blowtorch mounted at its bottom opening. The mixed powder is fed from the top and simultaneously heated and blended, after which it is transferred to a grinder using a conveyor belt. There, it is milled to yield the final cement product which is eventually packed in bags.

This cement is used as raw material in the production of concrete in a second process. An initial mixture comprising 15% cement, 10% water, one-quarter sand and half gravel is fed into a rotating concrete mixer where they are stirred until the concrete mix is ready for construction purposes.
