THE DUST BOWL

Globalisation

Globalisation consists of the growing integration of national economies in a worldwide market economy.

Causes of globalisation

• Progress of telecommunications: provides information in real time and permits contact between people anywhere on the planet.
• Improvement of transport: facilitates the transfer of goods and people around the world.
• Widespread adoption of capitalism and neoliberal ideals: has helped economic relations throughout the world.

External Structure of the Earth

• Lithosphere: It includes the crust and the upper mantle. It is the solid part of the Earth.
• Hydrosphere: It includes all the waters on Earth.
• Atmosphere: Gaseous layer that surrounds the Earth.
  • Troposphere (0–10 km): Where weather phenomena take place.
  • Stratosphere

The Fibre Placement Process

Automatically places multiple individual prepreg tows onto a mandrel at high speed, using a numerically controlled, articulating robotic placement head to dispense, clamp, cut and restart as many as 32 tows simultaneously. Machines are available with dual mandrel stations to increase productivity.

Advantages of fibre placement include:

• Processing speed
• Reduced material scrap
• Labour costs
• Parts consolidation
• Improved part-to-part uniformity

Often used to produce large thermoset parts with complex shapes.

Early European Expeditions: Portugal & Castile

• The monarchs of the Kingdoms of Portugal and Castile began to finance exploratory voyages.
• The Kingdom of Portugal sought to reach India via an easterly route, sailing around the coast of Africa to the Indian Ocean.
• These efforts continued until Bartolomeu Dias discovered the Cape of Good Hope in 1487. Later, an expedition led by Vasco da Gama followed this route, reaching Calcutta, India, in 1498.
• The Kingdom of Castile attempted to reach India via a western route, crossing the Atlantic Ocean. An expedition led by Christopher Columbus discovered a new continent, America, on October 12, 1492.

Christopher Columbus and the Discovery of America

• Christopher Columbus was a sailor, likely from Genoa, who

There are three types of reefs:

• Fringing Reef – Coral platforms grow out to sea attached to the mainland.
• Barrier

3. Recent immigration (1970–present): Large numbers of people have come from Mexico, China, Korea, India, and the Philippines, as well as other parts of Latin America and Asia.

7. 3 reasons why current immigration is different

First, a significant number of today’s immigrants have entered thecountry illegally, and thus their position is insecure.

Second, today’s immigrants are largely non-white. Race has formed a principal line of fragmentation within American society, and, as such, it threads its way insistently throughout the story of immigration. Race separated the experiences of voluntary immigrants in the distant past, for such minority immigrant peoples as the... Continue reading "Legal monism" »

A greater biomass;

Higher levels of species diversity;

Better soil structure and greater water retention;

Lower pH;

Plant species will be taller and longer living;

Greater community complexity and stability/equilibrium;

Greater habitat diversity;

and [2-4 max] the consequences.

e.g. Great Barrier Reef off the coast of Queensland, Australia

Human threats:

• Tourism; coral is very fragile and easily damaged by divers’ fins, touching coral, or breaking bits off for souvenirs;
• Overfishing can disrupt the balance of species in the food chain;
• Inadvertent damage from anchors and pollution from boats;
• Run-off of fertilizers from sugar plantations on the coast;
• Sewage and pollution from coastal settlements

China: Population 1.3 billion growing rapidly - 1 child policy used in the past

Most population in middle/middle-high income. Therefore spend a lot on luxury goods - more than any other country. Manufacturing hub Fashion industry - open to overseas brands, willing to spend a lot (not price sensitive) GDP growing fast, huge economy, dynamic & successful TRADE - surpassed US as a trading nation, rely heavily on emerging markets such as Brazil for exports but these EM cannot compete with their huge success and dominance. E-commerce industry is huge - no Facebook Whatsapp or Google, they use their own, WeChat has 900 million users. Use phones for everything. “Belt Road Initiative” - extend trade routes & integrate the economy. Opportunities... Continue reading "China: Opportunities and Strategies for Doing Business" »

2. (a) Río Grande de Santiago: Geographical Characteristics

[4 marks]

Describe the geographical characteristics of the Río Grande de Santiago downstream from La Presa.

1. (b) Human Activity and Water Flow Through Systems

[2+2+2 marks]

Explain three ways in which human activity can reduce the time taken for water to pass through the system.

Causes of Deforestation

• Procuring land for cultivation
• Building houses and factories
• Making furniture, using wood as fuel
• Natural causes such as forest fires and droughts

Effects of Deforestation

• Increase in atmospheric temperature due to increased carbon dioxide concentration, leading to global warming
• Severe droughts and floods
• Changes in soil nature, water holding capacity, and soil erosion, leading to desertification
• Destruction of wildlife habitat, making survival difficult

Conservation Measures

Biosphere

The part of the earth that supports life.

Biodiversity

The variety of organisms on earth, their interrelationships, and their relationship with the environment.

Flora and Fauna

Plants found in a particular area (flora) and animals found in a particular... Continue reading "Deforestation: Causes, Effects, and Conservation Measures" »
