Environmental Studies Quiz

Ecosystems

• Forests are considered one of the most stable ecosystems, alongside oceans and deserts.
• Stability in ecosystems is influenced by biodiversity, environmental conditions, and resource availability.

Forests

• Forests provide multiple benefits:
  • Reduce soil erosion, maintaining soil health.
  • Offer recreational opportunities like hiking and wildlife observation.
  • Contribute to economic development through timber and non-timber forest products.

Types of Coal

• Lignite, bituminous, and anthracite are classifications of coal based on carbon content and energy output.
• Each type has distinct properties and uses:
  • Lignite is soft and low in carbon, often used in power generation.
  • Bituminous is denser, used in electricity production and steel manufacturing.
  • Anthracite has the highest carbon content, known for its high energy efficiency.

Human Impact on Hydrosphere

• Development activities significantly affect water resources, leading to:
  • Water pollution, caused by industrial and agricultural runoff.
  • Other forms of pollution like air pollution, primarily related to industrial emissions or vehicle use.

Demography

• Demography is the scientific study of human population dynamics, including growth trends and future projections.
• It involves analyzing birth rates, death rates, migration patterns, and demographic transitions.

Water Conservation Methods

• Effective water conservation strategies include:
  • Rainwater harvesting, capturing rain for reuse.
  • Improving irrigation efficiency, optimizing water use in agriculture.
• Groundwater extraction and avoiding water wastage are essential practices, but excessive extraction is counterproductive to conservation efforts.

Ozone Formation

• The formation of ozone in the atmosphere is a photochemical reaction, influenced by sunlight, pollutants, and temperature levels.
• Ozone plays a crucial role in filtering harmful UV radiation but can be harmful at ground level, contributing to air quality issues.
