Explanation:

1. Carbon - cycle related questions: Natural sources of carbon include fossil fuels, decomposition of organic matter, and volcanic eruptions. Human - sourced carbon comes from burning of fossil fuels (coal, oil, gas), deforestation, and industrial processes. Plants contribute to the carbon cycle through photosynthesis (taking in carbon dioxide and releasing oxygen) and respiration. Carbon enters the atmosphere through processes like burning of fossil fuels and respiration, and human activities like deforestation and industrial emissions disrupt the carbon - cycle balance. Carbon moves through different parts of the Earth's system via processes such as photosynthesis, respiration, decomposition, and ocean - atmosphere exchange.
2. Earthquake related questions: Scientists measure and monitor earthquakes using seismographs which detect seismic waves. Earthquakes can affect the environment and natural landscapes by causing ground shaking, landslides, and tsunamis. Studying earthquakes is important for predicting future events, understanding plate tectonics, and developing strategies for disaster mitigation. Some regions are more prone to earthquakes due to their location on or near tectonic plate boundaries.
3. Seismic - wave related questions: P - waves (primary waves) are compressional waves that are faster and can travel through solids, liquids, and gases. S - waves (secondary waves) are shear waves that are slower and can only travel through solids. Seismic waves can tell us about the magnitude (size of the earthquake), location (epicenter), and the nature of the Earth's interior as they interact differently with various materials.

Answer:

1. Natural sources of carbon: Fossil fuels, decomposition of organic matter, volcanic eruptions.

• Human - sourced carbon: Burning of fossil fuels, deforestation, industrial processes.
• Plant contribution to carbon - cycle: Through photosynthesis and respiration.
• Carbon entering atmosphere: Burning of fossil fuels, respiration.
• Impact of human activities on carbon - cycle: Disrupt the balance.
• Carbon movement in Earth's system: Photosynthesis, respiration, decomposition, ocean - atmosphere exchange.

1. Measuring and monitoring earthquakes: Using seismographs.

• Effect on environment and landscapes: Ground shaking, landslides, tsunamis.
• Importance of studying earthquakes: Prediction, understanding plate tectonics, disaster mitigation.
• Prone regions: On or near tectonic plate boundaries.

1. P - waves and S - waves: P - waves are compressional, faster, can travel through solids, liquids, and gases; S - waves are shear, slower, can only travel through solids. Seismic waves tell about magnitude, location, and Earth's interior.
