1. How do the earth systems affect each other? All of the Earth systems depend on one another. The hydrosphere and atmosphere carry out evaporation and precipitation. The hydrosphere adds moisture and erosion to rocks, and the geosphere puts the water back into the oceans. The atmosphere gives the geosphere heat and energy then the geosphere puts the energy back into the atmosphere. The biosphere gets gases, heat, and energy from the atmosphere. It receives water from the hydrosphere and a living medium from the geosphere. 2. How can an understanding of environmental science aid in handling natural disasters? : It will be easier to find solutions about what to do or how to prepare for a natural disaster. By doing this it will cost less money to fix the damage and more people will stay alive. 3. What efforts can we make to create a sustainable future?: Make people aware of what is still going on. Tell them about the risk this will have on them and help them start to make a change. Reaction to findings: I was shocked to find out that volcanic eruptions cannot be prevented. It is bound to happen no matter the circumstances. https://eschooltoday.com/earth-system/interaction-of-the-earths-sphere.html
