Chapter 7: Earth and Space Science 

Learning Objectives: 

7.1 Describe ways the geosphere, biosphere, hydrosphere, and/or atmosphere interact to affect the Earth's materials and processes

7.2 Describe how plate tectonics explains the development and ongoing changes of the Earth's surface

7.3 Explain how solar energy, convection currents, and density influence ocean currents 

7.4 Explain how the effects of weathering or the rate of erosion by water, ice, wind, or vegetation contribute to the recycling of Earth materials

The Earth can be understood as a complex web of interconnected systems, all of which are powered by solar energy. The atmosphere is made up of a thin layer of gases. The geosphere is made up of water and land. The biosphere is made up of all living things on the globe, while the hydrosphere is made up of all water. All of these systems interact and have an impact on one another, constantly shaping and changing the globe and the life on it. 

Convection currents arise as heat energy circulates through the Earth's mantle, moving large continents and forming landforms like mountain ranges and deep ocean trenches. Volcanoes, earthquakes, and tsunamis are all examples of energy released in explosive bursts. As energy circulates through all of the earth's systems, it is continually changing.

Patterns can be seen in the flow of energy through Earth's systems, which is primarily driven by heat energy and results in convection currents. Winds, ocean currents, and forces that move massive continental plates are all accounted for by energy transfers in the form of heat. Great mountain ranges and deep ocean trenches, as well as earthquakes, volcanoes, and tsunamis, are all created by constant and unstoppable movement. 

Understanding earth systems allows us to forecast weather and climate patterns. Our planet is vulnerable to human actions. The more we understand how earth systems interact to influence our planet, the better we will be able to live in harmony with it and learn to harden the renewable energy sources that flow through our planet in the form of wind, current, and sunlight. 

That is all for today!
