What is the difference between weathering and erosion?
Difference Between Weathering and Erosion Weathering is the breakdown of rocks into smaller pieces by physical, chemical, or biological processes, like freeze-thaw or rusting. Erosion is the movement of these broken pieces by natural forces like wind, water, or ice. Illustration: Weathering occurs wRead more
Difference Between Weathering and Erosion
Illustration: Weathering occurs when rocks crack, while erosion happens when rivers carry those rocks away to form valleys.
See lessWrite in short about ecosystem services and their valuation.
Ecosystem Services and Their Valuation Ecosystem services refer to the benefits humans receive from nature, like clean air, water, pollination, and climate regulation. Valuation involves assigning monetary value to these services to highlight their importance in decision-making. Illustration: ForestRead more
Ecosystem Services and Their Valuation
Ecosystem services refer to the benefits humans receive from nature, like clean air, water, pollination, and climate regulation.
Valuation involves assigning monetary value to these services to highlight their importance in decision-making.
Illustration: Forests provide clean water and air; valuing these helps protect them from destruction, ensuring long-term environmental and economic benefits.
See lessDescribe in brief about photochemical smog.
Photochemical Smog Photochemical smog is a type of air pollution caused by the reaction of sunlight with pollutants like nitrogen oxides and volatile organic compounds (VOCs), primarily from vehicle exhausts. This reaction forms harmful chemicals such as ozone and peroxyacetyl nitrates (PANs). IllusRead more
Photochemical Smog
Photochemical smog is a type of air pollution caused by the reaction of sunlight with pollutants like nitrogen oxides and volatile organic compounds (VOCs), primarily from vehicle exhausts. This reaction forms harmful chemicals such as ozone and peroxyacetyl nitrates (PANs).
Illustration: In cities like Los Angeles, heavy traffic and sunlight create smog, which can cause respiratory issues.
See lessDifferentiate between conventional and non-conventional sources of energy.
Conventional vs Non-Conventional Sources of Energy Conventional Energy: These are traditional energy sources like coal, oil, and natural gas, which are finite and pollute the environment. Non-Conventional Energy: These are renewable sources like solar, wind, and hydropower, which are sustainable andRead more
Conventional vs Non-Conventional Sources of Energy
Illustration: Coal (conventional) vs solar power (non-conventional) for generating electricity.
See lessWhat is the principle of working of solar cell?
Principle of Working of a Solar Cell A solar cell works by converting sunlight into electricity through the photovoltaic effect. When sunlight hits the solar cell, it excites electrons in the material (usually silicon), causing them to move. This movement generates an electric current. Illustration:Read more
Principle of Working of a Solar Cell
A solar cell works by converting sunlight into electricity through the photovoltaic effect. When sunlight hits the solar cell, it excites electrons in the material (usually silicon), causing them to move. This movement generates an electric current.
Illustration: Solar panels on rooftops use this process to power homes by converting sunlight into usable electrical energy.

Soft and Hard Artificial Intelligence
Soft AI refers to systems designed to handle specific tasks with limited capabilities, such as voice assistants like Siri or Alexa. They operate within pre-set guidelines and cannot think independently.
Hard AI, also known as Artificial General Intelligence (AGI), aims to perform any cognitive task a human can. It has the potential to think, learn, and adapt autonomously.
Illustration: Soft AI is like a calculator, while Hard AI is similar to human-level decision-making.
