Environment – Medium Level – GK Questions

GIS integrates spatial data with attribute information, enabling visualization, analysis, and decision-making for environmental management and planning.

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

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.

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.

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

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

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.

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.

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

The tropopause is the transition layer where temperature stops decreasing with height, marking the upper limit of weather activity.

The ozone layer is located in the stratosphere, approximately 15-35 km above Earth's surface, absorbing most of the Sun's ultraviolet radiation.

NAPCC recognizes that climate change intensifies disasters; thus, adaptation measures are integrated into DRM to build resilience.

Non-structural measures use policy, planning, and information to reduce flood risk without physical infrastructure, complementing structural approaches.

The Disaster Management Act 2005 provides a legal and institutional framework for disaster management at national, state, and district levels.

Filling lakes, concreting over drains, and unplanned urbanization reduce infiltration and block natural water flow, increasing flood vulnerability.

NDMA, established under the Disaster Management Act 2005, is chaired by the Prime Minister to coordinate disaster response and mitigation.
