QUESTIONS
ROCKS AND THE UK PHYSICAL LANDSCAPE (Pages 44-46)
1a) How Are Igneous Rocks Formed? - Igneous rocks Are Formed When Molten Rock From The Mantle Cools Down And Hardens
1b) What Are Sedimentary Rocks Formed From? - Sediment
1c) Describe How Metamorphic Rocks Are Formed - Metamorphic Rocks Are Formed When Other Rocks (Igneous, Sedimentary Or Older Metamorphic Rocks) Are Changed By Heat And Pressure.
2) Give 2 Ways In Which Tectonic Activity Has Shaped The UK's Landscape - Plates Collided To Form The Scottish Highlands And Intense Heat And Pressure Caused By Plate Collisions Formed Hard Metamorphic rocks In Scotland And Norther Ireland
3) Outline The Characteristics Of Slate And Schist - Slate IS Formed In Layers And Is Strong Toi Weathering But Can Broken Into Thin Slabs Pretty Easily, However, Schist Is Made From Bigger Crystals Than Slate And Can Be Split Into Small Flakes
4) Explain How The UK Landscape Has Been Shaped By Glacial Periods - After The Glacial Periods Lots O Water Melted To Form Valleys And Deposited Material To Create
LANDSCAPE PROCESSES (Pages 47-48)
5)Give 3 Processes That Alter The Landscape - Weathering, Erosion And Post-Glacial River Processes
6a)Give An Example Of A Lowland Landscape - The Downs
6b)Outline How Physical Processes Have Created This Landscape - Large River Meander On The Permeable Clay And Floods Deposit Silt To Form A flood plain
7)How Does Forestry Change The Landscape? - The Roots of The Newly Planted Trees Suck Up All The Water From The Soil To Make The Area Dryer And The Trees Being Felled Are Doing The Opposite
8)How Does Settlement Alter The Landscape? - The People Need A Water Supply So They Would Suck Up All The Water To make The Landscape Dryer, They would Also Concrete Over Roads, Which Would Affect The Drainage Patterns
COASTAL PROCESSES AND LANDFORMS (Pages 49-53)
9)How Does Salt Weathering Break Up Rock - Saltwater Gets Into Cracks In The Rocks, When The Saltwater Dries, It Turns To Crystals And Expands, Which Puts Pressure On The Rock When This Happens Multiple Times It Will Eventually Break Up The Rock
10)What Are The 3 Types Of Erosion Caused By Waves? Explain How They Are Formed. - Hydraulic Power (When Water Compresses Air In The Cracks In The Rock),Abrasion (When Eroded Particles Scrape And Rub Against The Rock) And Attrition (When Eroded Particles Smash Into Each Other And Break Into Smaller Fragments)
11)What Is The Difference Between A Concordant And A Discordant Coastline? - Discordant Have Horizontal Layers And Concordant Has Vertical
12)What Are The Characteristics Of Constructive Waves? - They Are Low, Long And Low Frequency
13) Describe how erosion can turn a crack in a cliff into a cave.  - Waves Crash Into The Headlands Repeatedly And Inflict Hydraulic Power And Abrasion On It
14) How does longshore drift transport sediment along a coast? - It Carries Material Along The Coast, Following The Prevailing Wind
15) What are the characteristics of Destructive waves? - High, Steep And Low Frequency
16) Where do spits form? - Sharp Bends In A Coastline
17) What do stacks look like on a map? - Little Blobs On The Sea
18) How are cliffs shown on a map? - Little Black Lines
19) On maps, what do speckles on top of yellow shading tell you? - It's A Shingle Beach
HUMAN ACTIVITY AND COATAL MANAGEMENT (Pages 50-57)
20) Explain how agriculture can have a direct effect on the coast. - Clearing Vegetation Can Unbind The Soil Because The Roots Are Gone
21) How does development affect the coast? - It Can Change The Amount Of Transport And Deposition
22) Give one effect of coastal management on the coastline. - It Can Reduce Erosion
23) Describe one human process that is causing change on a named coastal landscape. - Over 11km Of The Holderness Coastline Is Protected By Hard Engineering Strats And There Are Groynes At Mappleton, Hornsea And Winthersea
24) Why does sea level rise increase the risk of coastal flooding? - Higher Tides Would Flood Areas More Frequently
26)What Are The Differences Between Hard And Soft Engineering? Give An Example Of Each - Hard Engineering Is The Use Of Man-Made Structures Built To Control The Flow Of The Sea And Reduce Flooding And Erosion And Soft Engineering Is The Use Of Schemes To Reduce The Effects Of Flooding And Erosion. An Example Of Hard Engineering Would Be A Groyne ,And An Example Of Soft Engineering Would Be Beach Replenishment
25a) Give two threats of coastal flooding to people. - Industries Would have To Shut Down And Housing Would Be Destroyed
25b) Give two threats of coastal flooding to the environment. - It Can Uproot Trees And Drown Small Animals
27) What are the disadvantages of using groynes for coastal management? Living Beings Can Smash Into It
28) What is strategic realignment? - a form of soft engineering that involves creating a new position for the coastline through engineering. In the case of managing coastal flooding, this means moving the boundary inland.
29) How Are coastal management strategies being made more sustainable? - Using More Soft Engeneering
