1. EARTH’S COMPOSITION Essential Questions

2. LEARNING OBJECTIVES:
SC.912.E.6.1 Describe and differentiate the layers of Earth and the interactions among them
SC.912.E.7.1 Analyze the movement of matter and energy through the different biogeochemical cycles, including water and carbon
SC.912.E.7.3 Differentiate and describe the various interactions among Earth systems, including: atmosphere, hydrosphere, cryosphere, geosphere, and biosphere
SC.912.P.10.4 Describe heat as the energy transferred by convection, conduction, and radiation, and explain the connection of heat to change in temperature or states of matter

3. What Are the Earth Systems and How Do They Interact With Each Other?
Everything that happens on our planet is part of a complex set of interactions between air, water, land, and life.
Use the following link to learn about the different Earth Systems and how they interact:

4. What Are the Different Layers of the Earth?
Use the following link to learn about the layers of the Earth:

5. How Does Energy Transfer Affect the interactions of the Earth’s Layers?
In the mantle are "convection currents,“ which make the mantle move.
The lower mantle heats up and rises and cools down then gets pushed down because it is heavier.
Use the following link to learn about convection currents:

6. What is the water cycle/hydrologic cycle?
A drop of water is in constant motion and in various states of matter (solid, liquid, gas).
Use the following link to watch the life cycle of a water drop:
Use the link below to learn about the water cycle:

7. What is the Carbon Cycle?
Chemical reactions allow carbon to recycle through the Earth’s spheres by various processes.
Use the following link to learn about the processes of the carbon cycle and how it cycles through the Earth’s spheres:

8. What is the Nitrogen Cycle?
Chemical and biological reactions allow nitrogen to recycle through the Earth’s spheres by various processes. Use the following link to learn about the processes of the nitrogen cycle and how it cycles through the Earth’s spheres:
