1 MAPS AND AERIAL PHOTOS REVISION IF THE FOLLOWING COMES UP IN THE SHORT QUESTIONS REMEMBER SCALE OF 1:1,100,000,000 MAP FROM A WORLD ATLAS LARGE AREAS WITH LITTLE DETAIL 1:250,000 SCALE OF CAR ATLAS MAP SCALE OF 1:50,000 YOUR EXAM MAP SMALL AREAS WITH GREAT DETAIL SCALE 1:1,000 STREET MAP OF NAAS

3 Headland Headla nd Cliff contours meet the coast Erosion features Bay Sea Stacks Headland

4 Contours meet the coastline indicating cliffs Inferred means we can presume they are there because they are The tighter the contour lines are, the steeper the cliffs are. Unless caves, arches or blowholes are named, they can be inferred along a coastline with cliffs

10 Tombolo Island is only fully accessible at low tide Crescent shaped beach

11 Yellow shading on map indicates permanent beach deposits Beach Purple/grey shading indicates deposits only visible at low tide Erne River keeps channel open Nose of sand spit is curved due to wave refraction Irregular contours indicate sand dunes

12 Sand spit Beach Irregular contour lines indicate sand dunes Tides and river currents keep the channel open Both sand spits have curved ends due to wave refraction Mud and silt deposited by tidal movements and river deposition

13

14 Sand dunes indicated by irregular contour lines Sandy beach area as indicated by yellow shading

16 Baymouth bar cuts off former bay area Lagoon

17 Irregular contour lines indicate sand dunes Nose of sand spit is curved towards the land due to wave refraction R Erne keeps channel open

18 FEATURES OF RIVER EROSION V SHAPED VALLEY, INTERLOCKING SPURS WATERFALL MEANDER DEPOSITION OX BOW LAKE LEVEE FLOOD PLAIN DELTA

19 River flowing in steep valley Small delta as river discharges into lake Meander as river flows in wide valley Lacustrine delta = river discharging into lake

22 FEATURES OF GLACIAL EROSION CORRIE ARETE PYRAMIDAL PEAK ALL FOUND IN UPLAND AREAS U SHAPED VALLEY GLACIAL/ FLUVIOGLACIAL DEPOSITION ESKERS GLACIAL SPILLWAY DRUMLINS

23 Cirque found high up in mountainous areas brown shading tightly packed contour lines on 2/3 sides show steep sides or back wall of Corrie

24 corrie

25 Steep back wall CORRIE Arete

26 U Shaped Valley look for river valley in or between mountains no contours along river side shows flat valley tightly packed contour lines along sides of valley shows steep sides made by eroding the interlocking spurs of the old river valley

27 Narrow u shaped valley with steep sides v.long ribbon lake

28 Some U shaped valleys can continue down onto lowlands so look for green colouring in valley any lakes found in valley even if no river occurs are RIBBON lakes

29 Steep sides Ribbon lakes

30 Drumlins are found on the Lowlands mainly in Cavan and Monaghan look for complete and rounded or nearly rounded contour lines the lines can have values to about 200m drumlins

31 An ESKER ridge will be shown on the map as an elongated but closed contour line. This can follow a road or just exist on the landscape. It is usually just ONE contour line. Esker ridge

33 Esker

34 Esker

35 Kettleholes will be found in Wexford and Waterford the landscape around them will have very irregular contour lines and they will be little lakes dotted on the landscape. Kettle holes

36 Meltwater Channels if a river or road exists on the lowlands (green shading) and it has tightly packed contour lines on either side, you can state that it is a meltwater channel

40 AREA OF MAP ======= LENGTH x BY BREADTH AREA OF SEA ===== COUNT ALL FULL BLUE BOXES, COUNT ALL BLUE BOXES GREATER THAN A HALF ADD BOTH TOTALS TOGETHER YOU MUST STATE YOUR ANSWER IN SQUARE KILOMETERS

41 REMEMBER HALF SCALE IS REPRESENTED AS 1: 100,000 IF YOU ARE ASKED TO DO SKETCH ON GRAPH PAPER, IT IS WORTH 2 MARKS IF YOU ARE NOT ASKED TO USE GRAPH PAPER, THEN YOU HAVE A CHOICE

42 Do you remember the different types of slopes????

50 SKETCH FOR A 20 MARK QUESTION SHOULD BE DONE IN 8 MINUTES IF NOT ASKED FOR HALF SCALE THEN MAKE IT SMALLER THAN ORIGINAL Rules for sketch map PUT IN A TITLE AND THE SCALE ONLY DRAW IN THE THINGS ASKED FOR DRAW IN THE NORTH POINT AND THE SUBZONE LETTER If there is a large river or lake in the area, add it in even if not asked for it. MUST DRAW IN THE COASTLINE, EVEN IF NOT ASKED FOR. ALWAYS INCLUDE A KEY DRAW AND LABEL ON SKETCH

51 THERE ARE 3 MAIN TYPES OF SETTLEMENT --- LINEAR HOUSES IN A LINE DISPERSED HOUSES DOTTED ALL AROUND THE PLACE NUCLEATED --- HOUSES CLUSTERED TOGETHER

52 IF ASKED TO EXPLAIN THE DEVELOPMENT OF A TOWN OR CITY REMEMBER GO BACK IN TIME AND IMAGINE A LANDSCAPE OF 2,000 YEARS AGO WHAT WOULD HAVE ATTRACTED YOU TO STAY HERE???

53 RIVER LOOK AT IRISH NAME NODAL POINT LOOK AT ANTIQUITIES FOR CLUES TO WHO SETTLED HERE FLOOD PLAIN WIDE CONTOURS
