To locate key features on an outline UK map, use the Tees-Exe Line as a primary guide. This imaginary boundary runs from the mouth of the River Tees in the northeast to the mouth of the River Exe in the southwest, separating the country into two distinct topographical zones.
Upland Areas (Located North and West of the line): Upland regions are rugged, mountainous areas typically over 200m above sea level.
Lowland Areas (Located South and East of the line): Lowland regions are flat or undulating areas usually below 200m above sea level.
On a map, these rivers drain water from high ground (sources) to the sea (mouths). Each river system is contained within a Drainage Basin, the area of land drained by a main river and its tributaries. The boundary of this basin, usually a ridge of high land, is known as the .
Ordnance Survey (OS) maps use grid lines to help pinpoint locations of physical and human features. Eastings are vertical lines where numbers increase as you move east (left-to-right). Northings are horizontal lines where numbers increase as you move north (bottom-to-top).
To describe physical geography features on an OS map, analyze Relief and drainage:
To describe human geography features (settlement and transport) on an OS map:
Students often confuse valleys and spurs when looking at V-shaped contours. Remember to check the numbers: if they decrease towards the centre of the 'V', it is a valley; if they increase, it is a spur.
When asked to 'describe' human land use, examiners expect you to cite specific map evidence, such as naming the 6-figure grid reference, quoting a label like 'Ind Est', or stating the exact road classification (e.g., 'A-road').
In grid reference questions, always remember the mnemonic 'Along the corridor, up the stairs' — you must read the Eastings (horizontal axis) before the Northings (vertical axis).
When describing landscapes in exam answers, use precise geographical terminology: use 'rugged' or 'mountainous' for upland areas, and 'undulating' or 'flat' for lowland areas.
Tees-Exe Line
An imaginary divide running from Northeast to Southwest England that separates the upland north and west from the lowland south and east.
Upland
Areas of high, rugged relief, typically over 200m above sea level.
Grampian Mountains
A major upland area in the Scottish Highlands that includes Ben Nevis, the highest peak in the UK.
Pennines
A chain of upland hills in Northern England, often referred to as the 'backbone of England'.
Lowland
Areas of gentle, low relief, usually below 200m above sea level.
The Fens
A low-lying area of reclaimed marshland in East Anglia, containing the lowest point in the UK.
Lowland Basin
A low-lying area where sedimentary rocks have been deposited over time, often forming a large saucer-like shape in the landscape.
Drainage Basin
The total area of land drained by a main river and all of its tributaries.
Watershed
The boundary of a drainage basin, which usually follows a ridge of high land.
River Severn
The UK's longest river, originating in the Cambrian Mountains of Wales and flowing into the Bristol Channel.
River Thames
The UK's second-longest river, flowing through southern England and London into the North Sea.
Eastings
The vertical grid lines on an OS map where the numbers increase as you move eastwards (left-to-right).
Northings
The horizontal grid lines on an OS map where the numbers increase as you move northwards (bottom-to-top).
Relief
The height and physical shape of the land, including the steepness of slopes and the altitude.
Contour Lines
Brown lines drawn on a map that connect points of equal height above sea level.
Spot Height
A black dot on an OS map with a number next to it, indicating the exact height of the land in metres at that specific point.
Sinuosity
The degree of curviness or bendiness in a river's course.
Interlocking spurs
Finger-like ridges of land that overlap in a V-shaped valley, forcing a river to flow around them.
Nucleated
A settlement pattern where buildings are clustered closely together, often around a central feature like a church or crossroads.
Linear
A settlement pattern where buildings are developed in a line, typically following a road, river, or valley floor.
Dispersed
A settlement pattern characterized by isolated buildings or farmhouses scattered across the countryside.
