Welcome to Geography is all around us.blogspot.com

This website is designed for Geography lovers everywhere and in particular to those studying Geography. I hope you enjoy the site.

Geography (from Greek γεωγραφία - geografia) is the study of the Earth and its lands, features, inhabitants, and phenomena. A literal translation would be "to describe or write about the Earth". The first person to use the word "geography" was Eratosthenes (276-194 B.C.). Four historical traditions in geographical research are the spatial analysis of natural and human phenomena (geography as a study of distribution), area studies (places and regions), study of man-land relationship, and research in earth sciences. Nonetheless, modern geography is an all-encompassing discipline that foremost seeks to understand the Earth and all of its human and natural complexities-- not merely where objects are, but how they have changed and come to be. As "the bridge between the human and physical sciences," geography is divided into two main branches - human geography and physical geography.

Rivers

As a flows from its source to its mouth, its gradient (slope) and valley shape change. There are 3 different stages in the course of a river, i.e.:
* _______________________________
* _______________________________
* _______________________________

Life cycle of a River






















River terms:
Term
Definition
Source


The high ground that separates one river basin from another.
Estuary

Mouth


The point at which a tributary joins the river

A small stream or river that joins up with a larger one
Basin

Course


All the material being carried by the river
Flood plain



The Life Cycle of a River
Like humans, rivers go through a life cycle: Youthful stage à Mature stage à Old-stage
The Youthful stage (Upper course)
The river begins its life-cycle in the _________________. Its aim is to reach the lake or sea as quickly as possible so it makes its way downwards by means of v_________
e____________. Both its vol____ and load are small. Vertical erosion loosens material along the ____ of the river.

A river erodes in four ways or processes.
1______________________________________________________________________________________________________________________________________________________________________________________________________________
2______________________________________________________________________________________________________________________________________________________________________________________________________________
3______________________________________________________________________________________________________________________________________________________________________________________________________________
4______________________________________________________________________________________________________________________________________________________________________________________________________________
The amount of erosion that takes place depends on:
1:Volume:_______________________________________________________________________________________________________________________________________
2:Velocity:_______________________________________________________________________________________________________________________________________
3:Underlyingrock:_________________________________________________________________________________________________________________________________4:Load:________________________________________________________________________________________________________________________________________
Landforms/ Features of the Youthful stage
V shaped valleys
Interlocking spurs
Waterfalls

V-Shaped Valleys
The river is starting its life-cycle in the mountains. Both the volume of the water and the ______ are small. The river wants to enter the lake or sea as quickly as possible so it starts to erode _____wards forming a ___ shaped valley, e.g. the youthful stage of the river Liffey.
Formation of a V-shaped valley











Interlocking Spurs
In the ____________ stage the river does not have enough power to go through obstacles, e.g. g______e so it goes ___________ them forming interlocking _________. Interlocking _________ are areas of high ground that jut out from _______ sides of a young __________ valley and ______ into one another like pieces of a jigsaw.
V-Shaped valley with interlocking spurs






Waterfalls
Waterfalls occur when the river meets a layer of ________ rock and soft rock. The ______ rock will be eroded much faster than the _______ rock causing the riverbed to steepened forming a __________. The force of the falling w_______ cuts a hole called a _________ pool. The falling ________ also cuts under the ____________ to form a over_____. This eventually ___________. This process repeats itself and the waterfall gradually __________ upstream. A good example of a ____________ the Torc Waterfall in ________________.
Formation of a Waterfall












Landforms/ Features of the Mature stage
In the ________ stage the river’s _________ has increased because many _________ have joined it. In this stage _________ erosion takes place. In the Mature Stage of a river, ____________ erosion leads to the following features:
Meanders
Ox-box lakes
Meanders
Meanders are c_______ or loops that develop along the course of a river. Meanders are formed by __________ on the outer bank and ___________ on the inner bank. Meanders appear as bends along the river’s course. As the river flows around a slight _______, the water on the ____side bank flows more __________ and has ________ power to erode the river bank. The water on the ________ bank flows more s_________, and as a result the river will ___________ some of its load there. As the river flows downstream the meanders become more ______________. Meanders are found along the course of the R. Shannon.
Ox-Bow Lakes
An Ox bow lake is a ______________ shaped lake found on the _________ __________
of a river. It is a feature of e__________ and d___________. Ox bow lakes develop from well-developed __________. Erosion continues to take place on the _______ bank and the _______ of the land becomes narrower. During a __________ the river may _____ through it. The river now flows __________ ___________ instead of following the meander. As the sediment is d________ed, it seals both ends of the abandoned meander loop – thus forming an ____ ______ lake. Example – R. _________.
Formation of an Ox Bow Lake



















Landforms/ Features of the Old stage
The river is now entering the end of its life c________. All the eroded and transported material is now _____________ along the bed and banks of the river. Two features of the old stage include:
Levees
Deltas
Levees
Levees are _________ ________ ___ ____________ found along the banks of some rivers in their ____ stage. The river is now flowing over f____ land. The river _______
material on its bed causing the water to rise. Sometimes this may cause the river to o___f_____ depositing its material on its_______. These banks are ________ and are often reinforced to prevent ________and damaging low-lying land, e.g. R. S_____.

Levees develop in the old stage of a river









Deltas
Deltas are formed at the _______ ___ _ _______. When a river flows into the sea, it ____
Its speed and d________ its load of sediment. If the tides and currents are not strong enough to carry it all out to sea, the deposits begin to _______ ___. The m______ of the river soon becomes clogged and the river breaks up into smaller _________ called dis____________. Example –Mouth of the R. N_____.
Delta


River Transportation
A river is an agent of t_________t, carrying material from upland to ___land areas. It can do so in the following ways:
à Rolling _______________________________________________________________
à Bouncing _____________________________________________________________
à Suspension ___________________________________________________________
à Solution ______________________________________________________________
