ہوا کی سمت کی پیمائش کے لیے کون سا آلہ استعمال ہوتا ہے؟
A. Wind Vane
B. Galvanometer
C. Anemometer
D. Hygrometer
Check answer and explanation
Answer: Wind Vane
Explanation A wind vane (also called a weather vane ) shows the direction from which the wind is blowing. Usually installed on rooftops or meteorological stations. Works with a rotating pointer that aligns with the wind direction. Last verified on 01-02-2026
Explanation Rainfall is measured using a Rain Gauge . It collects rainwater and measures it in millimeters (mm). Widely used in weather forecasting and meteorology . Helps in studying climate and agriculture patterns. Last verified on 31-03-2026
Explanation Temperature: High during the day (often above 35°C or 95°F), cooler at night. Rainfall: Very low, usually less than 250 mm (10 inches) per year. Humidity : Low, making the air feel dry. Examples: Sahara Desert (Africa), Arabian Desert (Middle East), parts of Arizona and Nevada (USA). Vegetation is sparse, and plants/animals are adapted to conserve water.
Explanation Dry air from Earth's atmosphere contains 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and traces of hydrogen, helium, and other "noble" gases (by volume), but generally a variable amount of water vapor is also present, on average about 1% at sea level.
Explanation Nitrous Oxide is significantly more potent at trapping heat than methane and carbon dioxide N2O absorbs infrared radiation very strongly and stays long in the atmosphere. It has a GWP of approximately 265–298, making it nearly 300 times more potent than CO₂ per unit
درج ذیل میں سے کون سا عامل موسمیاتی تبدیلی میں مثبت کردار ادا نہیں کرتا؟
A. Non-renewable energy
B. Afforestation
C. All of these
D. Emission Trading System
Check answer and explanation
Answer: Non-renewable energy
Explanation Climate change is mainly affected by energy use and environmental policies. Non-renewable energy (coal, oil, gas) increases carbon emissions, so it does not positively contribute . Afforestation helps reduce CO₂ and improves climate. Emission Trading System encourages reduction of emissions. Therefore, non-renewable energy is harmful for climate balance.

Explanation Weather is a short-term phenomenon which describes the state of the atmosphere at a particular place and time. The climate of a place indicates the weather of a place over a long period of time . The difference between Weather and Climate is a measure of time. AGM 30.4.23
وہ جانور جو پودے یا دوسرے جانور کھا کر اپنی خوراک حاصل کرتے ہیں انہیں _____ کہتے ہیں؟
A. Decomposers
B. Consumers
C. Producers
D. Predators
Check answer and explanation
Answer: Consumers
Explanation Consumers are the animals that get their food by eating plants or other animals. This includes herbivores (plant-eaters) , carnivores (meat-eaters), omnivores (both plant and meat-eaters) , and decomposers (break down dead organic matter ).
