Study Notes
The Earth's Atmosphere
- The Earth's atmosphere is a layer of gases that surrounds the planet.
- It is essential for life on Earth, as it provides oxygen for breathing, protects us from harmful radiation, and regulates the Earth's temperature.
- The atmosphere is composed of 78% nitrogen, 21% oxygen, and 1% other gases.
- These gases are held to the Earth by gravity.
Structure of the Atmosphere
- The Earth's atmosphere is divided into several layers based on temperature.
- The layers include the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
Troposphere
- The troposphere is the lowest layer of the atmosphere.
- It is where most weather occurs.
- It extends up to about 10 kilometers above the Earth's surface.
- Temperature decreases with altitude in this layer.
Stratosphere
- The stratosphere is located above the troposphere and extends up to about 50 kilometers.
- It contains the ozone layer, which absorbs harmful ultraviolet radiation from the sun.
- Temperature increases with altitude in this layer.
Mesosphere
- The mesosphere is located above the stratosphere and extends up to about 80 kilometers.
- It is the coldest layer of the atmosphere.
- Meteors burn up in this layer, generating shooting star effects.
Thermosphere
- The thermosphere is located above the mesosphere and extends up to about 500 kilometers.
- It is the hottest layer of the atmosphere.
- This layer absorbs the most extreme ultraviolet and x-ray radiation from the sun.
The Ozone Layer
- The ozone layer is a region of the stratosphere that contains a high concentration of ozone gas.
- Ozone absorbs ultraviolet radiation from the sun, which is harmful to life on Earth.
- It is located in the lower stratosphere, extending about 15 to 35 kilometers above the surface of the Earth.
- The ozone layer has been depleted in recent decades due to the release of man-made chemicals called chlorofluorocarbons (CFCs).
- The depletion of the ozone layer is a major environmental concern, as it could lead to increased levels of skin cancer and other health problems.
Climate Change and the Atmosphere
- The Earth's climate is changing due to the increasing levels of greenhouse gases in the atmosphere.
- Greenhouse gases trap heat in the atmosphere, causing the Earth to warm.
- The primary greenhouse gases are carbon dioxide, methane, nitrous oxide, and fluorinated gases.
- Human activities, such as burning fossil fuels, deforestation, and agriculture, are the major contributors to the increase in greenhouse gas concentrations.
- Climate change is a serious threat to life on Earth, as it could lead to more extreme weather events, rising sea levels, and other devastating consequences.
The Indian National Congress
- Founded in 1885, the Indian National Congress (INC) emerged as a platform for educated Indians to voice their grievances against British rule.
- Early leaders were primarily moderate and sought reforms within the existing British framework, advocating for greater Indian representation and a gradual transition towards self-rule.
- The Congress's initial appeal was primarily to the English-educated elite of urban centers.
- Gradually, the Congress evolved into a platform for a wider range of political aspirations, attracting leaders with more radical perspectives.
- The Congress's early demands were centered around achieving a greater role for Indians in the British administrative system.
- The Congress's policies and strategies evolved over time, influenced by shifting political realities and the growing nationalist sentiment within India.
- The INC ultimately played a pivotal role in shaping India's independence movement, uniting diverse social groups and mobilizing public opinion against British rule.
Moderates & Extremists
- The early INC leaders, known as Moderates, believed in achieving self-rule through constitutional means and by appealing to British sense of justice and fair play.
- Moderates aimed to secure increased representation in legislative councils and work towards a gradual process of self-governance.
- Their approach emphasized reform, education, and the use of petitions and appeals to the British government.
- Extremists, emerging within the Congress later, were more radical and advocated for more assertive measures to attain independence.
- They saw the need to challenge British authority directly, emphasizing the potential for mass movements and the use of non-cooperation.
Formation of Muslim League
- The Muslim League, founded in 1906, emerged as a separate platform representing the interests of Muslims in India.
- Its initial aim was to safeguard the rights and interests of Muslims, who felt that their concerns were insufficiently addressed by the Congress.
- Over time, the League's agenda became more politically charged, leading to increased competition and tension with the Congress.
Home Rule League
- The Home Rule League, founded in 1916, emerged as a campaign demanding self-rule for India.
- The League's main objective was to promote and advocate for Swaraj, or self-rule, through a mixture of constitutional means and public pressure.
- The League's campaign contributed to the growing momentum for Indian independence, mobilizing public opinion and raising awareness of the need for a greater level of autonomy from British rule.
The Non-Cooperation Movement
- The Non-Cooperation Movement, launched in 1920, was a significant turning point in the Indian independence movement.
- This non-violent movement called for Indians to boycott British institutions and goods, including courts, legislative councils, and educational institutions.
- The movement was suspended in 1922 due to a violent incident in Chauri Chaura, where protestors clashed with police, leading to casualties.
- The non-cooperation movement, while short-lived, served as a powerful demonstration of Indian national unity and resistance against colonial rule.
Civil Disobedience Movement
- The Civil Disobedience Movement, launched by Mahatma Gandhi in 1930, aimed to challenge and undermine British rule.
- The movement involved various forms of non-violent resistance, including the Salt Satyagraha, where people defied the British salt tax.
- The movement aimed to pressure the British government into granting India greater autonomy and eventually independence.
Forward Bloc
- Founded in 1939, the Forward Bloc was formed by Subhas Chandra Bose.
- It aimed to push for immediate independence and even considered seeking support from the Axis powers during World War II.
- The Forward Bloc represented a more radical wing of the Indian nationalist movement, seeking complete freedom from British rule without compromise.
Quit India Movement
- The Quit India Movement, or the August Movement, was launched in 1942.
- It demanded immediate independence from British rule following the rejection of the Cripps Mission proposals, which aimed at post-war constitutional changes.
- The movement involved nationwide protests, strikes, and boycotts, leading to a significant crackdown by the British authorities.
Partition of India
- After World War II, the British government announced its intention to grant India independence.
- The decision to partition the country into India and Pakistan was prompted by communal tensions and the demand for a separate homeland for Muslims.
- The partition resulted in mass displacement, violence, and loss of life, marking a tragic chapter in Indian history.
Indian Independence Act 1947
- The Indian Independence Act 1947 marked the end of British rule and the beginning of independent India and Pakistan.
- The Act granted independence to India and Pakistan, while transferring power and responsibility to the newly formed governments.
Independence of India
- India achieved independence on August 15, 1947.
- The country faced significant challenges as it embarked on its journey as a newly independent nation.
Factors Leading to Independence
- The rise of Indian nationalism, fueled by growing awareness of colonial exploitation and a yearning for self-rule, played a pivotal role.
- The leadership of Mahatma Gandhi in promoting non-violent resistance inspired Indians to fight for freedom.
- The participation of Indians in World War II, which highlighted British reliance on Indian manpower, further strengthened the independence movement.
- International pressure on Britain to grant independence, combined with the weakening of the British Empire after the war, also contributed to India's eventual independence.
