Glaciation Flashcards

Question

How is are ribbon lakes formed ?

Answer 1

* The Glacier finds it difficult to erode the hard rock, but easy to erode the soft rock. This creates a rock basin * when the glacier melts it fills the rock basin to create a ribbon lake * moraine is deposited at the end of the ribbon lake

Answer 2

* material is deposited underneath the glacier as ground moraine * ground Moraine is sculpted to form drumlin shapes by further ice movements

Answer 3

• they have been transported and deposited by a glacier

Answer 4

A Boulder that is different to the bedrock it is sitting upon

Answer 5

Lateral moraine is material that has been plucked by freezethaw weathering and has been carried down the sides of the valley

Answer 6

Medial moraine is found at the centre of the glacier and it is when two moraines join together

Answer 7

Ground moraine is material dragged underneath a glacier which, when deposited forms the valley floor

Answer 8

Terminal moraine marks the maximum advance of a glacier. It is the material deposited at the end of a glacier

Answer 9

Recessional moraine forms behind and parallel to the terminal moraine. They mark the retreat in the glacier when it's stationary for long periods of time

Answer 10

• Corrie lake called red tarn • arête called striding edge - they are located just east of lake thirlmere • hanging valley at grisedale • ribbon lakes • Keswick is situated on the floor of a U-shaped valley

Answer 11

* extensive agriculture such as animal grazing is well suited to glaciated Upland areas * sheep were introduced too many upland Estates during the 1800s * some land owners have introduced dear for venison meat and highland cattle * coniferous woodland occupies 2 million hectors of land in the UK, much of it is in upland areas * Wood is used as timber for furniture and building constructions

Answer 12

* it is the most important source of uplands areas income * it's employs more people than any other industry in these places * glaciated areas attract walkers and mountain climbers * The Lake District is highly accessible and has a mild climate

Answer 13

* there is tough resistant rock that is not found in lowland areas * A lack of population means that there are fewer dangers when explosives are used to shatter rock into blocks * the Rock types have a high economic value * in the Lake District it is slate - which is used as roofing and decorative materials * Lake District has 13 active quarries

Answer 14

* military training * reservoirs * wind turbines * Hunting * forestry

Answer 15

* have a maximum visited numbers * signing to show permanently out of bounds areas * seasonal closure to give the site a chance to recover * restricted activities such as camping is restricted to designated campsites

Answer 16

* footpath erosion - 15.8 million people visit the Lake District Every year * businesses thrive from tourism * visitors let dogs off the lead which can worry lambs and sheep * visitors can climb over old walls knocking them down * visitors by the houses so none are available for local people and later on pushing up the prices of the houses beyond levels of affordability * visitors can litter * Jobs are created such as watersport instructors, however wages can be seasonal and therefore low in the winter * traffic causes pollution

Answer 17

* diverting the course of paths and fencing off the old footpath to allow time for the vegetation to recover from footpath erosion * making signs * educating people about the country code * sign saying take your litter home

Answer 18

* beautiful views of lakes and mountains | * visit highlands for activities like water sports, rock climbing, hiking and mountain climbing
