Study Notes

Importance of Wetlands

Wetlands serve as crucial habitats and breeding sites for diverse species, including birds, frogs, and fish.
They provide essential water sources for various plants and animals, contributing to local ecosystems.
Wetlands act as natural filters, cleansing water by removing both soluble and insoluble pollutants.
They function like sponges, absorbing excess water to prevent flooding during heavy rainfall.
During dry periods, wetlands help maintain river and stream flows by releasing stored water.

Impact of Wetland Loss

Human population growth leads to habitat destruction, resulting in a loss of 50% of global wetlands over the past century.
Wetland loss significantly reduces biodiversity, as many species lose their natural habitats, leading to population declines or displacement.

States of Matter: Solids, Liquids, and Gases

Matter is composed of particles that have varying arrangements and movement depending on their state.

Solids

Particles are tightly packed in a fixed pattern with minimal spacing, restricting movement.
They vibrate in place, contributing to the solid structure and fixed shape of materials like bricks.

Liquids

Particles are closely packed but have more space between them compared to solids, allowing for greater freedom of movement.
Liquids flow and take the shape of their containers due to the less rigid arrangement of particles.

Gases

Particles are spaced far apart and move freely in all directions at high speeds.
Gases lack a definite shape or volume, filling their containers regardless of size.

Biodiversity and Wetlands

Destruction of wetlands disrupts habitats, leading to decreased biodiversity as many species face extinction or migration challenges.

Water Quality and Wetlands

Wetlands enhance water quality by filtering harmful substances like soaps and fertilizers from water.
Microorganisms in wetland ecosystems break down waste, helping to purify water supplies.

Matter and Particle Movement

Matter consists of small particles with spaces between them, influencing the ability to mix substances like water and stones.
Particle movement is dependent on energy; heating increases movement and can lead to phase changes.

Methods of Water Purification

Clean water is essential for survival, and many people globally lack access to safe drinking water.

Sieving

A sieve separates larger impurities from water but does not remove harmful microorganisms.

Filtering

A cloth filter can remove larger particles but does not eliminate germs, rendering the water unsafe for drinking.

Settling

Allowing dirty water to stand lets solids settle at the bottom, while cleaner water remains on top.

Water Purification Techniques

Decanting: Separates clear liquid from settled solids by carefully pouring it into another container.
Boiling: Kills germs and parasites, making water safer; requires cooling time afterward.
Chemical Treatment: Chlorine and purification tablets are added to eliminate pathogens in clean water.

Municipal Water Purification Processes

Municipalities use filtration through metal screens to remove debris before treating water with sand filters and chemicals like chlorine.
To ensure the removal of remaining germs, chloramine is periodically added to maintain water quality.

Importance of Clean Water

Access to clean water is vital; contaminated sources pose health risks due to invisible germs and parasites present even in seemingly clear water.
