examples of earth's systems interactions grade 7

📚 Quick Study Guide

• 🌍 The Geosphere: This includes all the solid parts of Earth, from the core to the surface. Think rocks, minerals, and soil.
• 💧 The Hydrosphere: All the water on Earth, including oceans, lakes, rivers, ice, and groundwater.
• 🌿 The Biosphere: All living things on Earth, including plants, animals, and microorganisms.
• 💨 The Atmosphere: The layer of gases surrounding Earth, mainly nitrogen and oxygen.
• 🔄 Interactions: These systems constantly interact! For example, volcanoes (geosphere) release gases into the atmosphere. Rain (hydrosphere) erodes rocks (geosphere). Plants (biosphere) take carbon dioxide from the atmosphere.
• ☀️ Energy Source: The sun is the primary energy source that drives many of these interactions, like the water cycle and weather patterns.
• 🌡️ Climate: The long-term patterns of temperature and precipitation are influenced by the interactions between these systems.
