Three Types of River Delta - Fan, Bird's Foot and Tooth (UEB uncontracted)

by Rnib

This page shows three maps of river delta. Each image is surrounded by an image border. There is a locator dot shown, which will be at the top left of the page when the image is the correct way up. The image in the top of the page is of an arcuate delta. The river Nile goes up the page from the bottom centre of the image. It branches into many distributaries in a fan like shape, the delta getting wider towards the sea. The Mediterranean coastline goes from left to right across the page. Part of the Mediterranean Sea fills the top half of the image. The characteristics of arcuate deltas are lots of short distributaries which fan out as they go downstream. The image in the middle of the page is a bird's foot delta. The Mississippi River goes from the top left of the image down and right making a peninsular sticking out into the Gulf of Mexico. In the centre of the image it branches into a few main distributaries. Each distributary lays a finger of silt in the sea so that the delta resembles a bird's foot. The image in the bottom of the page is of a cuspate delta. The Tiber River goes from the top right, meandering towards the bottom centre of the image. It has very few distributaries and an even spread of deposition making a shape similar to a tooth. The Italian coast goes from near the bottom right towards the top left of the image. The Tyrrhenian Sea fills the left half of the image.

Fossil fuel power station (UEB uncontracted)

by Rnib

This is a labelled cross section diagram of a fossil fuel power station, showing the process of producing electrical power from fossil fuels such coal, coke, gas and oil, and also wood and bio fuels (oils and gases from plant sources). There is a locator dot shown, which will be at the top left of the page when the image is the correct way up. The image is surrounded by a dashed line image border. The diagram is in four main sections. From left to right these are: the boiler, the steam turbine, the generator and the cooling tower. The fuel comes into the boiler on the left of the page through a pipe and is burnt to create a high temperature inside the boiler. To the right is the steam turbine. A pipe carries water from the bottom of the turbine enclosure to the left, into a heat exchanger in the boiler, where it is heated to create steam at high pressure. This travels to the right through a pipe to rotate the turbine blades at high speed. To the right, a generator, driven by the rotation of the turbine produces an alternating electric current, which is fed into the national electricity grid. To the right of the generator you can find a cooling tower. Hot water from a condenser in the turbine housing is pumped to water jets in the cooling tower and sprayed into a tank to cool. The cold water is then pumped back to the condenser in the turbine housing to condense the steam from the turbine.

Volcano types (UEB contracted)

by Rnib

There are three types of volcano shown on this page. At the left is a composite volcano made up from alternating layers of rock and lava; at the top right is a shield volcano made from many layers of runny lava; and at the bottom right there is an ash volcano formed from lava and ash. Each diagram has a dashed line image border. At the bottom left of the page, stretching across the diagram, is a layer of molten magma (the mantle). In the middle of the diagram, the magma has forced its way through the Earth's crust and is erupting from the top of the volcano, and also through two smaller vents on either side. At the top right of the page is the much flatter form of a shield volcano with magma at the bottom of the diagram forcing its way through the Earth's crust. At the bottom right is an ash volcano. You can see the lava and ash forcing its way upward from the magma layer at the bottom of the page. There is a locator dot shown, which will be at the top left of the page when the image is the right way up.

World globe centred on Africa (UEB uncontracted)

by Rnib

This is a globe map centred on the African continent. As the land masses shown are on the curved surface of the Earth, this image will be distorted, especially at its edge. There is a locator dot shown, which will be at the top left of the page when the image is the correct way up. Land is shown on the tactile image as a fine dotted texture and the sea by fine horizontal lines, these are green and blue respectively on the Large Print image. This globe map represents the Earth as seen from space, directly above the Africa. Central Africa is in the centre of the map, up the page is Europe and to the right of this, Asia. To the left of Africa are the Atlantic Ocean and the eastern half of South America, on the edge of the globe.

Leaf Cross Section (UEB uncontracted)

by Rnib Bookshare

This page shows an image of a cross section through a leaf. There is a locator dot shown, which will be at the top left, when the image is the correct way up. The image is surrounded by a dashed line image border. There is a small key in the bottom left corner of the tactile versions. The central vein is on the right and a small part of the leaf blade is to the left of the page. The vein is full of two sorts of vessel which transport water and material around the plant. The leaf blade is made of four layers. The upper and lower epidermis is at the leaf surfaces. The palisade and spongy layers form the mesophyl tissue in the centre of the leaf.
