 Inputs, Outputs, Transfers, Storage...Woahhh Characteristics of the Drainage Basin Inputs : in the form of precipitation and snow Outputs : this is where water is lost from the system, either through being carried to sea (by rivers) or through evapotranspiration.  Within the system some water is: Stored : In rivers, soil, vegetation. Transferred : Infiltration, through-flow etc.  Key:    INPUT             STORAGE             TRANSFERS             OUTPUTS Precipitation This term refers to the act of water/moisture (in its solid or liquid form) falling from clouds in the sky.  Examples include: Rain, hail and snow.  Influencing Factors: Presence of Vegetation  Time of Year Altitude  Latitudinal Location Evaporation This is the process by which the suns energy converts water into water vapour. Influencing Factors: Atmospheric Conditions (temperature, humidity, hours of sunshine, wind speed) Time of Year Transpiration This a biological process by which water is lost from a plant through t

 Yes, the shape of rivers is important in understanding aspects of hydrology. Lets look at it.  Image: From Seneca College Pressbooks What is Morphometry? Morpho - Shape Metry - Size  Morphometry refers to the shape , size and form of rivers in a drainage basin. This allows us to make objective comparisons on the similarities and differences of a drainage basin: Establish a stream hierarchy Law of stream order: the relationship between stream order and stream number Stream Ordering  First Order- initial tributaries (no prior connections)  Second Order- a stream joined by two first order streams  Third Order- a stream joined by two second order streams   Law of Stream Order  Two stream segments of an equal order, will create a segment of a higher order. However the order of a stream will remain the same if a lower order segment joins a higher order segment.  Bifurcation Ratio This is the relationship between the number of streams in one order to one that is of a higher order.  Signific

 Woah, WAIT, is that... EARTHQUAKE!!! Image: From Tappity What is an Earthquake?  An earthquake is a series of shocks, seismic waves or tremors that result from a sudden release of pressure.  Focus : Point below the surface where seismic waves radiate from the source/origin  Epicentre : The point on the surface immediately above the focus of the earthquake, this is where the most damage can be noted.  Causes of Earthquake Activity: Physically Induced: Tectonic plates moving against each other or where there is volcanic activity Human Induced: Mining, drilling to the earth, underground explosions N.B: These contribute to the inducing of earthquakes as the create shock waves which cause changes (pressure changes) in the rock strata.   Types of Earthquake Waves:  Two types of seismic waves can occur, following the event of an earthquake.  1. Body Waves : Shock waves that are transmitted upwards to the surface from the focus. It can be divided into: Primary/Pressure/P Waves : Fastest, move

 Rivers, Rivers, Rivers, DRAINAGE BASIN Image: From Quora What is a Drainage Basin? A drainage basin can be described as an area of land drained by a river and it's tributaries.  A well developed drainage basin consists of:  Spring : The point from which water flows from with earth's surface.  Source : The point where a rivers begins Mouth : The point at which a river ends (and meets a larger body of water, usually an ocean or sea) Stream : Also can be called a consequent stream, this a body a fresh water, flowing through s channel Tributary : Also can be called a subsequent stream, this is a smaller river that joins the consequent stream Deferred Junction : This is where a tributary flows parallel to a consequent stream before joining it.  Distributary : Smaller rivers located at the mouth that flow away from the consequent stream (usually towards a large body of water)  Watershed : An area of highland that separates one drainage basin from another. 

No, population distribution and population density are not the same thing...here's the difference: Image: From Conde Nast Traveller India  What is Population Distribution?  Population Distribution is the way people are spread across a geographical area. Population distribution is usually uneven and over time, changes. Population distribution can be represented on a dot map .  What is Population Density? Population Density refers to the number of people that leave per square unit area. Population Density can be represented on a choropleth map.   Population Distribution Formula: On a global scale, population density and distribution patterns can be influenced by physical factors such as:  Relief Climate  Water Supply Vegetation  Soil On a smaller scale, namely local or regional, patterns of population distribution and density can be influenced by  Economic factors Social factors  Political factors 

Migration can be both beneficial and harmful to a country  Image: From Agrim Housing Finance  Advantages of Migration: The are that people move or migrate from becomes less crowded. This can ease the pressure placed on the resources of the country of origin.  The country of origin benefit from remittances. Remittances are monies sent by migrants (mostly family members) abroad, to people in another country (their home country) The government can tax this money, thus making an income from it. The host (receiving) country experiences brain gain. Brain gain is the process by which highly skilled and educated workers migrate to the country for various reasons . This is beneficial to the receiving country as they will see a spike in their human resources.  Those skilled workers who migrate to another country, may come back to their home country and can share any new skills or knowledge they acquired abroad, to further the development of the country.  Disadvantages of Migration:  The biggest
