Environment – GK Questions

CAAQMS use automated analyzers to measure pollutants like PM2.5, PM10, NO2, SO2, CO, and O3 continuously, providing real-time data for public awareness.

CPCB coordinates NAMP through a network of monitoring stations across India to assess ambient air quality and trends of key pollutants.

Remote sensing uses sensors to detect and record reflected or emitted energy, enabling large-scale environmental monitoring without physical contact.

The IRS satellite series by ISRO provides data for agriculture, forestry, water resources, disaster management, and environmental studies.

Forests intercept rainfall, reduce runoff velocity, enhance infiltration, and stabilize soil, thereby regulating stream flow and mitigating floods.

Launched under NAPCC, the Green India Mission targets enhancing forest cover, biodiversity, and livelihoods of forest-dependent communities.

Mangroves have specialized adaptations like pneumatophores for oxygen uptake in waterlogged, saline coastal environments.

Van Panchayats are community-managed forest councils in Uttarakhand and Himachal Pradesh, empowering locals to conserve and use forest resources sustainably.

Clearing forests for agriculture, roads, dams, and urbanization are primary drivers of deforestation, leading to habitat loss and biodiversity decline.

JFM, initiated in 1990, partners forest departments with village communities for sustainable forest management and sharing of benefits.

Tropical wet evergreen forests of the Western Ghats and Northeast India harbor exceptional biodiversity with numerous endemic flora and fauna.

Agroforestry combines agriculture and forestry practices to enhance biodiversity, improve soil health, and increase farm productivity sustainably.

Social forestry promotes tree planting by communities for fuel, fodder, timber, and environmental benefits, reducing pressure on natural forests.

Deciduous forests have trees that lose leaves seasonally to conserve water during dry periods, common in tropical and temperate regions.

Jet streams are high-altitude, high-speed wind bands that influence weather patterns and aviation routes globally.

Greenhouse gases like CO2, CH4, and water vapor absorb outgoing infrared radiation from Earth's surface and re-emit it, warming the atmosphere.

Trade winds form due to air moving from high-pressure subtropical zones toward the equatorial low, deflected by the Coriolis effect.

Earth's rotation deflects moving air and water to the right in the Northern Hemisphere and left in the Southern Hemisphere, affecting wind patterns.

A barometer measures atmospheric pressure, which is essential for weather forecasting and understanding atmospheric dynamics.

Ozone molecules absorb ultraviolet radiation, converting it to heat, which causes temperature to rise with altitude in the stratosphere.
