ELS MODULE 2 PART 2

Earth's Layers

• Outer core is composed mainly of liquid iron and nickel.
• Inner core is solid and consists primarily of iron and nickel.
• The asthenosphere, located just below the crust and above the lower mantle, exhibits plasticity, allowing for slow flow.

Physical Properties of Earth's Layers

• The upper mantle is thicker and less dense compared to the lower mantle.
• The lower mantle is thinner but denser, contributing to the dynamic processes of mantle convection.

Nutrient Cycles in Natural Systems

• The oxygen cycle is crucial for moving oxygen through the atmosphere, biosphere, and lithosphere, supporting life on Earth.
• The carbon cycle describes the continuous movement of carbon through Earth's systems, including reservoirs in the atmosphere, oceans, and terrestrial biosphere.

Water Cycle

• The water cycle outlines the continuous movement of water through various stages such as evaporation, condensation, and precipitation, impacting weather patterns and ecosystems.

This quiz explores the composition of the Earth's core, highlighting the roles of liquid iron and nickel. Discover the significance of these elements and their properties. Test your knowledge and learn more about the fascinating structure of our planet's interior.
