Geographical Skills Revision

METHOD:  AIM 2 - Sediment Size and Roundness

  • At intervals of 0.5m or 0.2 m we randomly grabbed five stones 
  • we measured the longest side in mm using a ruler
  • judged roundness by comparing them to diagrams ranging from 'very rounded' to 'very angular' another member of our group tallied these results into a table
Strengths and Weaknesses: 
  • one day to visit all the sites so 5 was the most accurate way for us to record the results
  • By comparing them to diagrams our results would be comparable to people who used the same diagram
  • Could have improved investigation by using the same person at everysite to determine the roundness as perceptions can differ
  • Unlikely that people would pick up the larger rocks so our results were biased towards smaller rocks
  • By  measuring the longest side of each rock you get a reliable comparison


Method of Data presentation: 
BOX PLOT
s used to display information about the range, the median and the quartiles. It is usually drawn alongside a number line, 
We plotted the results of site 2 as this is where our anomoly of 912mm occured
Biggest and smallest size// upper and lower quartile// median
Because our measurements were tallied in a box of ranges e.g. from 0.-5mm the upper quartile and the median were the same. It was also difficult because 4 of our range measurements actually applied to this site and we would need five to complete the graph correctly.
Our biggest sediment size was an anomaloy from the rest of the group

Opposition to the Tsarist Regime

Intelligentsia:

  • Size and influence grew in the 1870's 
  • Improvements in law courts had created critical lawyers 
  • Zemstva's encouraged debate
  • Some were inspired by the Nihilist Movement - who wanted to create an entirely new society and were believers in religion and science and so were also in opposition to the Russian Orthodox church, not just the Tsar. In 1862, they created a manifesto called 'Young Russia" calling for "bloody and merciless revolution" - They were rumoured to be responsible for fires in St Petersburg in June 1862 .

  • KEY FIGURE: Mikhail Bakunin believed in the removal of the state and the superiority of the peasant. Bakunin wanted collective ownership of land and income should be determined by the number of hours worked. Bakunin was influenced by Alexander Herzen. In 1869 he and Nechaev published "Catechism of a Revolutionary" . His was an influence on the beliefs of radical group - "Land and Liberty"
  • Alexander Herzen was slightly different because he wanted a system of socialism which involved the mir ( the village commune where peasants worked) with a central governmental regime. He published the book "The Bell". 
  • Zemstva's were set up in 1864 and the Zemstvo of St Petersburg demanded a central body to co-ordinate the regional Zemstva
Populists:
 In 1871 a radical peasant illegaly returned to St Petersburg to continue Herzens plea to "Go to the people". He murdered someone and fled. However he inspired the Chaikovsky Circle which produced pamphlets and banned books . There was a group of about 2,000 with their leader Key Figure: Pyotr Lavrov who went to the country in 1874 to "go to the people". They then became known as the Nardoniks.
They believed in Socialist ideas which were taking from the rich to give to the poor and sharing land among the peasants.
However the peasants didn't agree with the populists and were very hostile towards them, by autumn 1874 1,600 had been arrested.

Key Figure: Mikhail Romas - tried to set up a cooperative selling fruit and veg in return for manufacutred goods. But peasants were suspicious as to why his prices were so much cheaper. and his assitant who had been a peasant was brutally murdered. 

From these failed attempts at "going to the people" the radical group "Land and Liberty" was set up in 1877. They found positions in peasant communes as doctors, teachers and work men however peasants still weren't swooned by this approach.
In their second year (1878) they assasinated General Mezmetsev who was head of the Third Section ( the secret police). Tsar was worried about how these assasinations were gaining the group popular support. 
Dmitrii Milyutin said "the present leaders in government are powerless, not only to solve the problem, but even to understand it" and said the govt. "demands basic reform"

However in 1979 Land and Liberty split into the Black Partition and the People's Will:

Black Partition:
  • Organised by Georgi Plekhanov
  • Wanted to share the black soil provinces of Russia
  • Peacefull - spread propoganda 
  • Weakened by arrests in 1880-1881 
The People's Will:
  • Led by Timofei Mikhailov - who planted a spy in the Third Section
  • Bigger Group
  • Advocated Violence
  • 1879 declared Tsar needed to be removed- although it said it would withdraw the threat if the Tsar agreed to a constitution

Significance of Opposition:
- Marxism took a more definite form
- moderate educated Russians began to deman reform from below - specifically members of the Zemstva
- Populism stopped revolutionary activity being underground - which madepeople and govt more aware of ublic feeling and the threat of change. 
- Failure of open trials and bad secret police force reinforced the belief that the regime had lost direction
- People high in the ranks were become reactionary which was making it difficult for the Tsar to run the country the way he wanted
- H had given people a taste of reform which encouraged them to want more

Monsoons



Quiz based on the video:

What is a monsoon?
Where are they most often associated with?
What happens in the Summer monsoon?
Where depend on Summer Monsoons?
Why is agriculture dependent on these monsoons?
Where do winter monsoons start?
Why are they less powerful?
What are they associated with?

THE THREE CAUSES OF MONSOONS:

1. HEATING DIFFERENCES: The extreme differential heating/cooling of large land masses in relation to the sea this impacts pressure and winds


2. HIMALAYAS: The Himalayas interfering with atmospheric circulation peaks of up to 8,000m

3. ITCZ: The Northwards movement of the ITCZ in the Northern Hemisphere




( skip to 50seconds)

QUIZ:
What happens to the air over land in the summer?
 What happens to the air over the sea?
Is this a low-pressure or high-pressure system?
Where do the winds blow from? Why?
When is the wet monsoon season?
So what happens in the winter?
What pressure is dominating now?
Where do winds blow from?
When is the dry monsoon?
What has happened with the monsoons recently??

SUMMER MONSOON: JUNE- SEPTEMBER ( WET)

  • ITCZ moves northwards as the sun moves towards the Tropic of Cancer
  • This increases the insolation over northern India which causes the air to rise in places like India, Pakistan and Central Asia.
  • Highest Temperatures usually occur just before the rainy period.
  • Tropical Maritime and Equatorial Maritime air is diverted north east by the Coriolis effect
  • When the rainy period begins the clouds block the solar radiation which reduces the monthly temperatures
  • Rainfall (orographic and convectional) increases when the air is forced over the Himalays and the Western Ghats. This releases latent heat and increases the instability causing more air to rise.
  • E.G. Cherrapunji recieves 13,000mm of rain in 4 months
Revision Task: Make a diagram formed poster explaining each of these points in order

WINTER MONSOON: DECEMBER- MAY (DRY)

  • The subtropical jet stream and the ITCZ move just south of the equator
  • There is high pressure and low temps over land and low pressure and higher temps over sea
  • Winds are very dry and get drier as they go over the Himalayas
  • This usually results in clear skies and sunniness
  • Bombay recieves less than 100mm of rain during these 8 months compared to 2,000mm in the summer monsoon

The Three Seasons:
  1. Rainy Season June- September the late arrival can be really serious for agriculture, espcially intense on the Western Ghats and the headland of the Bay of Bengal
  2. Cold, Dry Season October - January Low temps winter conditions
  3. Hot Dry Season Feb - May  All over India, Especially the North, Convectional thunderstorms and tropical cyclones effect Bay of Bengal and other placess
