| 🇬🇧 | 🇬🇧 |
| What is Abrasion ? | Rocks and other materials that are carried by the sea are picked up by strong waves and thrown against the coastline. |
| What is Attrition ? | A process of erosion. The material is moved along the bed of a river, collides with other material, and breaks up into smaller pieces. |
| What are Aquifers? | A body of porous rock or sediment that has been saturated with ground water |
| What best describes the process of Baseflow? | The usual level of a river, the part of a river's discharge fed by groundwater |
| What is a Catchment area? | Drainage basin |
| What is the Channel network? | The pattern of linked streams and rivers within a drainage basin |
| Define Clean water | Water that is fit for human consumption and is therefore relatively free from pollutants |
| Define Condensation | When water vapour is cooled and changes state to form water droplets |
| What is a confluence ? | Where two rivers/streams meet |
| What is Corrasion? | A process of erosion, sometimes known as abrasion. This is when fine material rubs against the river bank. The bank is worn away, by a sand-papering action called abrasion, and collapses. |
| What is Corrosion? | A process of erosion. Some rocks forming the banks and bed of a river are dissolved by acids in the water |
| What does a cumec measure ? | Cubic metres per second, the unit for river discharge |
| What is a Dam? | A large structure, usually of concrete, sometimes earth, built across a river to hold back a large body of water (reservoir) taken for human use |
| Describe/define deposition ? | The dropping of material that was being carried by a moving force, such as running water |
| Describe/define Rivers discharge ? | The quantity of water flowing in a river channel at a particular location and time |
| Describe/define a drainage basin Exam 2020 Exam June 2020 State one feature of a drainage basin | It is a water system involving external inputs and outputs, where the amount of water in the system varies over time. It is the area where water from precipitation (rain/snow..) drains downhill into a common body of water such as a river or lake. [The area drained by a river and its tributaries.] |
| What is erosion ? | The wearing away and removal of material by a moving force, such as running water |
| What is a flood plain ? Explain the formation of a flood plain | The flat land lying either side of a river which periodically floods |
| Define Hydraulic Action | A process of erosion. The sheer force of water hitting the banks of a river |
| What does a hydrograph show ? | A graph showing the discharge of a river over a given period of time |
| What is the Hydrological Cycle ? | The global movement of water between the air, land and sea |
| Describe the characteristics of Impermeable material ? | If a material is impermeable, it does not allow water to pass through it |
| What are interlocking spurs ? | A series of ridges projecting out on alternate sides of a valley and around which a river winds |
| Describe a levee ? | A raised bank of material deposited by a river during periods of flooding |
| Describe/define Mass Movement ? | The movement of weathered material down a slope due the force of gravity |
| What is a meander ? | A winding curve in a river's course |
| What is an OxBow Lake? | A horseshoe-shaped lake once part of a meandering river, but now cut off from it |
| Define Pollution ? Q Explain one way pollution can affect water quality? | The presence of chemicals, dirt or other substances which have harmful or poisonous effects on aspects of the environment such as rivers and the air A. Wastewater from agriculture (1) can cause increased eutrophication of the water (1) because of the high concentration of chemicals (1). • Plastics dumped in rivers (1) can cause a decrease in water quality (1) damaging river ecosystems / affects the food chain (1). • Discharge of sewage (1) lowers water quality/making water dirty (1) threatening human health (1). • Chemicals have been added to the water (1) downstream impact on wildlife (1) which could disrupt food ch |
| What is a Reservoir ? | An area where water is collected and stored for human use |
| What is a River Regime ? | The seasonal variations in the discharge of a river |
| What is Saltation ? | A process of transportation. smaller stones are bounced along the bed of a river in a leap-frogging motion |
| What is Solution ? | A process of transportation. Dissolved material is transported by the river. |
| What is Suspension ? | A process of transportation. Fine material, light enough in weight to be carried by the river. It is this material that discolours the water |
| What is a store in the hydrological cycle ? | Features, such as lakes, rivers and aquifers, that receive, hold and release water |
| Define Stormflow | The increase in stream velocity caused by a period of intense rainfall |
| What is Stream Velocity ? | The speed at which water is flowing in a river at a given location and time |
| What is Traction ? | A process of transportation. Large rocks and boulders are rolled along the bed of the river |
| What are transfers ? | The movement of water between stores in the hydrological cycle |
| What is transport (in relation to the water cycle) ? | The movement of a river’s load |
| What is a Waterfall ? | Where a river’s water falls vertically, as where a band of hard rock runs across the river channel |
| What is a Watershed ? | The boundary between neighbouring drainage basins |
| Define Weathering | The breakdown and decay of rock by natural processes, without the involvement of any moving force |
| What is a Trough ? | These are valleys formed by the glacial processes of weathering, erosion and transportation. They have steep sides and flat floors. Unlike V-shaped river valleys, glacial troughs are straight as they have truncated any interlocking spurs which existed prior to glacial advance |
| What is peak discharge on a hydrograph | Maximum amount of water held in the channel. |
| What is peak rainfall | Maximum amount of rainfall (millimetres). |
| What is lag time ? | The time taken between peak rainfall and peak discharge. |
| What is the rising Limb | Shows the increase in discharge on a hydrograph. |
| What is the falling limb ? | Shows the return of discharge to normal/base flow on a hydrograph. |
| Define/describe abstraction | Removal of waterfrom rivers, lakes or groundwater for human use |
| Define transpiration | When the plant opens its stomata to let in carbon dioxide, water on the surface of the cells of the spongy mesophyll and palisade mesophyll evaporates and diffuses out of the leaf. This process is called transpiration . |
| Define/describe Agricultural runoff | Water from farm fields due to irrigation, rain, or melted snow that flows over the earth that can absorb into the ground, enter bodies of waters or evaporate. |
| Explain one way agriculture can affect water quality | Fertilisers/pesticides (1) could seep into the ground (1) and contaminate ground water (1). • Liquid from farm slurry (1) could enter the river (1) causing eutrophication (1). • Deforestation (1) could increase run off (1) carrying more soil and silt into rivers (1). • Cattle waste/cattle in river (1) directly into the river (1) contaminating the water (1). |
