Rocks, Resources And Scenery

Question 1

Answer 1

Permian period

Question 2

What are the characteristics of an igneous rock?

Answer 2

Bumpy
Big particles
Rough
Coarse
Can be different colours
Resistant to erosion
They are composed of interlocking crystals

Question 3

What are the characteristics of sedimentary rocks?

Answer 3

Smooth
Plain colours
Fine grain
Light
Particles are tightly packed
Usually from layers called beds
They often contain fossils
Although some can be tough most are weaker the igneous and metamorphic rocks

Question 4

What are the characteristics of metamorphic rocks?

Answer 4

Smooth
Has metal
Light
Particles are tightly packed 
Fine grain
Heat and pressure changes the rock
They are crystallised 
They often exhibit layers (not beds) called cleavage and bauding
Resistant to erosion
Very tough

Question 5

Example of igneous rock

Answer 5

Granite

Question 6

Example of sedimentary rock

Answer 6

Chalk

Question 7

Where can granite be found

Answer 7

On Dartmore

Question 8

Where can you find chalk

Answer 8

South England-the needles

Question 9

Where can you find slate

Answer 9

In Wales

Question 10

What is the rock cycle

Answer 10

magma cools to from IGNEOUS rock, which is uplift and brought to the surface by the movement of tectonic processes. Here the rock is exposed to weathering and erosion. The deposits are transported and are deposited. As time goes on. Ire waste is piled ontop, this means the deposited are compressed which will create SEDIMENTARY rock. The sedimentary rock may experience pressure during volcanic eruption and it will change as a result to a METAMORPHIC rock. As it cools it forms IGNEOUS rock again.

Question 11

What type of landscape does granite form

Answer 11

Tors and moorland areas

Question 12

What type of landscape does chalk and clay form

Answer 12

Escarpments and valleys; dry valleys and spring lines

Question 13

What type if landscape do Carboniferous Limestone form (surface)

Answer 13

Limestone pavements
Swallow holes
Dry valleys
Resurgence 
Limestone gorges

Question 14

What type of landscape do Carboniferous limestone form (underground)

Answer 14

Caverns
Stalactites
Stalagmites
Pillars
Curtains

Question 15

What are the uses for granite landscapes on Darmore?

Answer 15

Building stone
Kitchen surfaces
Several reservoirs have been constructed in steep valleys
Mainly extensive sheep farming on poor pasture and in harsh conditions.

Question 16

Why is granite used as a building stone?

Answer 16

Because it is strong and not effected by weathering

Question 17

Why has granite been used in several reservoirs which have been constructed in steep valleys

Answer 17

It is an impermeable rock

Question 18

Why is granite used for pastoral farming

Answer 18

Because granite forms in upland areads

Question 19

What is Carboniferous Limestone used for

Answer 19

Buildings

Question 20

Why is Carboniferous Limestone used for building

Answer 20

Because it is hard

Question 21

What is the disadvantage for using Carboniferous limestone

Answer 21

It dissolves in weak acid (chemical weathering-carbonation)

Question 22

Uses of limestone

Answer 22

Attractive for tourists
Quarried to be manufactured into cement
Good for ww lacking, mountain biking, climbing
Good in industrial and farming to neutralise soil
Generally thin, good for sheep cattle
Building stone and in dry-stone-walls as field boundaries

Question 23

Uses of chalk

Answer 23

Quarried to make cement
Used in industry and farming to neutralise soil
Produces reasonable fertile land but thin soil, good for sheep cattle
Produce aquifers source of water
Popular with naturalists due to rich wilf-life

Question 24

Uses of clay

Answer 24

Making bricks and pottery
It produces fertile soil but they are often waterlogged. This means clay soil is best for sheep and cattle farming, but can be good for crops if the have been properly drained
Not very attractive

Question 25

Reasons for quarries

Answer 25

Limestone can be used for many things and quarries lower these prices Lots of employment More people with incomes Supplies 2million tonnes of limestone a year to "Hope Cement Work" to make cemen

Question 26

Reasons against quarries

Answer 26

``` Noisy-huge explosions Pollution-1 million tones of CO2 a year Left huge eyesore on the landscape-not good for attracting tourists Dust-health problems Lots of lorries-pollution, noise Wild life habitats and farming destroyed Local rivers pollution ```

Question 27

Case study for quarry

Answer 27

Hope Quarry

Question 28

How is Hope Quarry being managed

Answer 28

It's the responsibility of the park authority to stick a balance the conservation all needs of the environment and the economic and social needs of the area

Question 29

What is extracted from Hope Quarry

Answer 29

Limestone

Question 30

What is extracted from the Eden Project

Answer 30

China clay

Question 31

How was the Eden sit restored

Answer 31

``` Restoration after the used They have the Eden sessions; Ellie Goulding, Jessie J, The XX Garden center Children activities Biggest and fastest zip-wire Nature reserve Plan a rout-paths School visits-educational Lakes-sailing, fish live there Farming near by ```

Question 32

Where is chalk found on the geological timescale?

Answer 32

It is found 75 million years ago, along with clay during the Cretaceous period

Question 33

What was the initial landform of chalk and clay?

Answer 33

Initially the layers of chalk and clay were tilted by the collision of the African and Eurasia plates. The soft clay was then eroded faster than the more resistant chalk, leaving escarpments (chalk hills) behind. Because of the angle of the tilt, these escarpment have two distinctive sides; a steeper slop (scarp slope) and a gentle slop (dip slope)
