UK Landscapes
As part of the landscapes topic, we look at what the UK looks like.
We use the physical landscape to study it. Geographers use 3D maps
called ‘relief maps’ which show us what the ground looks like. It
might be hilly, or have rivers, or coasts or open fields etc.
This map shows areas of highland and lowland. The orange and brown areas
represent high ground like mountains and the green areas show low land like
fields.
TASK: Locate three places you have visited or want to visit. Add them to the
map and say if they are highland areas or lowland areas.
Another skill geographers need is how to describe. This is where you say what
you see when looking at a picture, map or diagram. There is no need to explain
why it is that way. Try giving it a go and describing what the relief looks like in
the U.K. A good way to do this is by saying what you can see in different
sections of the U.K
For example ‘In the north of the U.K there is lots of highland areas. In Scotland
there are a lot of mountains.
(see how I’ve used directions like North and place names like Scotland to help
describe what I can see)
TASK: Describe 3 things you can see on the relief map of the UK.
Rivers
A major part of the UK landscape are rivers. They are everywhere, including
the river Calder in Brighouse, which flows past at the bottom of the hill from
school. The next section in this booklet will teach you about the appearance
and features of a river from start to finish.
Your task will be to read through the information and extract the bits you need
to complete the empty boxes on the diagrams. This will give you an annotated
diagram of a river once you have finished.
Rivers have 3 distinct sections to study, the upper course, middle course and
the lower course. All three look very different and create different features.
The Upper Course
A river starts on high ground, usually mountains, from a small puddle that is
created by rainwater collecting in it and eventually spilling over. This starts the
flow of water and is called the source. It is a trickle of water that a person
could just step over.
After a while the water begins to erode the ground it runs over and begins to
get deeper. This is called vertical erosion. This is the start of the river getting
bigger as it flows downhill. As it erodes down into the ground the shape of the
river becomes like a ‘V’ shape. The river has now begun to create some
features. The space the water flows through is the river channel, the muddy
banks along the edge are called the river sides. The bottom of the river is
called the river bed.
There are usually lots of rocks and plants in the river as the flow of the water is
quite slow and not powerful enough to move them out of the way.
One of the most spectacular features you see in the upper course of a river is a
waterfall. These are created when the river meets two types of rock. One really
hard to erode and one that is easy to erode. Think if you squeezed marble and
chalk in your hands, the chalk would crumble but the marble wouldn’t. The
water erodes one but not the other creating a waterfall that actually moves
backwards up the river!
See the diagram below to see the complete process
The water flows
over the hard rock
layer on top but
erodes the soft
rock underneath
creating a cliff.
As the water
splashes into the
water below it
erodes more soft
rock and creates an
overhang.
Eventually the hard
rock overhang
becomes too heavy
and breaks off
falling into to
plunge pool below.
The waterfall has
no moved
backwards up the
river and the
process starts
again.
The Middle Course
As the river begins to get faster and gathers more water the shape of the river
begins to change too. Firstly, the river starts to widen. The water erodes the
sides of the river and it begins to become more of a ‘U’ shape rather than a ‘V’.
This process is called horizontal erosion. They become too wide to cross
without help and because of the extra water the flow is much faster.
A feature that you will see in the middle course is called a meander. This is a
sweeping curve in a river that makes it appear bendy. If you see the Eastenders
titles you can see the river Thames has many big meanders in.
This is caused by the river hitting some hard rock and being unable to erode
through. This means the river turns a different direction creating a bend. Over
time this becomes bigger and bigger as the water rushes through and erodes
more and more of the earth.
This is the Amazon river, see how
the course of the river is curvy
rather than a straight line. This is a
great example of meanders.
The Lower Course
By the time the river has reached the lower course it has done most of its
erosion. It is now really deep and really wide and you probably need a boat to
get across. The lower course often sees humans beginning to use the river too.
We transport things, use them for tourism, swimming, fishing etc. So pollution
becomes a bit of a problem and the rivers become quite dirty looking.
The lower course is important as this is where the river ends. All rivers end
when they reach a large body of water, either a large lake or the sea/ocean.
When a river meets the sea/lake this is called the mouth. It slows down the
flow of the water and the rivers appear quite calm.
TASK: Using the information fill in the blank boxes on the river diagrams. You
should add key terms and a little explanation to show what is going on. Some
boxes will have some help in them some will be blank.

Mini Quiz! (answers at the end)
1. What is the start of a river called?
2. What direction does vertical erosion go in?
3. What feature do you often see in the upper course?
4. What feature do you often see in the middle course?
5. What is the mouth of a river?
The Coast
Now we have followed a river from start to finish we end up at the sea. This
brings us to another landscape feature, the coastline. In the U.K. we have a lot
of coastline because we are an island and therefore surrounded by sea.
TASK:
Why is the coast important to us?
As humans we use the coast for so many different things. If you explore the
U.K you will see that the coast looks different everywhere you go, this is
because we use it for many reasons which shape the aesthetics (looks) of the
landscape.
TASK: Use the photos and your own knowledge to list different ways we use
the coastline. After each one write a sentence to explain why that is important
to us. (try to think as many as you can)
Example: We use the coast for photography, it is very picturesque and
photographers can take amazing photos of the scenery and sell them to make
money.
TASK: Imagine you are sitting on this beach. Write a postcard that
DESCRIBES and EXPLAINS what you can see and everything you have
been doing on this beach today.
Things to think about:
• Landscape, activities, tastes, smells, feelings, rocks, trees, flowers, animals
