Geography Homework Part 2
RIVER LANDSCAPES AND PROCESSES (PAGES 59-61)
1)What Does A River's Long Profile Show? - It's Gradient
2)Describe The Cross Profile Of A River's Lower Course. - Very Wide And Flat
3)What Is The Difference Between Vertical And Lateral Erosion? - Vertical Erosion Deepens The River Valley And Lateral Erosion Widens The River Valley
5)How Does A River's Discharge Change Along With It's Course? - The Sediment Load Gets Smaller In Size
6)Describe The Process Of Freeze Thaw Weathering - Water Gets Into Cracks In Rocks, The Water Freezes And Expands, The Water Un-Freezes, If This Happens Multiple Times It Can Break The Rock
7)What's The Difference Between Erosion And Attrition? - Erosion Is The Result Of Having Been Being Worn Away Or Eroded, While Attrition Is Wearing Or Grinding Down By Friction.
4)Compare The Sediment Size And Shape In A River's Upper And Lower Courses. - In The Upper Course The Sediment IS Made Up Of Large, Angular Stones, While On The Lower Course The Sediment Is Made Up Of Much Smaller And Rounder Stones
8)Name 2 Processes Of Transportation. - Traction And Saltation
9)When Does Deposition Occur -   When A River Slows Down
RIVER LANDFORMS (PAGES 62-65)
10)Where Do Waterfalls Form? - Over An Area Of Hard Rock Followed By An Area Of Softer Rock.
11)What Are Interlocking Spurs? - Hills That Interlock With Each Other Because Of Erosion.
12a)Where Is The Current Fastest On A Meander? - On The Outside Of The Bend.
12b)What Feature Of A Meander Is Formed Where The Flow Is Fastest? - River Cliffs.
13)Name The Landform Created When A Meander Is Cut Off By Deposition. - Ox-Bow Lake.
14)What Is A Flood Plain? - A Wide Valley Floor On Either Side Of A River That Gets Flooded If A River Overflows.
15)Outline The Main Features Of A Delta. - Low Lying Area Where The River Meets The Sea Or Lake, Lots Of Tiny Split Up Rivers Called Distributaries.
17)Give Two Pieces Of Map Evidence For A Waterfall. - Close Contour Lines And Black, Blocky Lines.
16)What Do The Contour Lines On A Map Show? - How High An Area Is.
18)Give Two Pieces Of Map Evidence For A River's Lower Course. - No Contour Lines, Wide River.
RIVER LANDSCAPES, SEDIMENT LOAD AND DISCARGE (PASGES 66-67)
19)Explain How Climate Influences Sediment Load. - More Water = More Power = Higher Load
20)Give  Ways Geology Influences River Landscapes. - Hard Rocks Are Harder To Erode So Produce Less Load, Soft Rocks Are Easier To Erode, So They Produce More Load
21)What Is Soil Creep? - When Soil Particles Move Down A Slope Because Of Gravity
22)What Is River Discharge? - The Volume Of Water That Flows Through A River
23)What Is Lag Time? - The Delay Between Peak Rain Time And Peak Discharge
24)Describe One Physical Factor And One Human Factor That Alter Storm Hydrographs. - Geology - Natural - Water Can't Filtrate Through Impermeable Rocks So It Creates More Runoff, Urbanisation - Human - Water Cant Filtrate Through Impermeable Surfaces, So Creates More Runoff
RIVER FLOODING AND MANAGEMENT (PAGES 68-70)
25)Outline 2 Physical Factors That Increase The Risk Of Flooding On A Named River - River Eden, Very, Lake District Has Lots Of Hard Rocks
26)What Human Activities Are Causing Flooding On A River You Have Studied? - River Eden. Lots Of Development In Carlisle Lead To The Flood Plain Not Being Able Of Absorb Water, Natural Wood And Heathland Have Been Cleared Leading To The Flood Plain Not Being Able To Absorb Water
27)Outline 2 Ways In Which Land Use Change Is Increasing The Risk Of Flooding - River Eden. Lots Of Development In Carlisle Lead To The Flood Plain Not Being Able Of Absorb Water, Natural Wood And Heathland Have Been Cleared Leading To The Flood Plain Not Being Bale To Absorb Water
28a)Give 2 Threats Of Flooding To People - Drowning And Houses Being Destroyed
28b)Give 2 Threats Of Flooding To Wildlife To The Environment - Farmland Could Get Ruined And River Banks Can Be Eroded
29)Define Hard Engineering - Man-Made Structures Built To Control Flooding
30)Define Soft Engineering - Schemes Set Up To Not Harm The River But Still Stop Floods From Happening
31)Describe The Costs Of Using Flood Walls To Reduce The Risk Of Flooding - Very Expensive, Block The View OF The River And Look Ugly
32)Describe The benefits Of River Restoration - Little Maintenance Required And Cheap Nice To Look At
