Study Notes
Earth's Surface Composition
- The Earth's surface has three primary compositional layers: Crust, Mantle, and Outer Core.
Lithosphere and Asthenosphere
- The Lithosphere is the outermost layer of the Earth, containing the entire Crust.
- The Asthenosphere is a layer of the Earth beneath the Lithosphere, characterized by high temperatures and pressure.
Inner Core and Outer Core
- The Inner Core is a solid layer of the Earth's composition, due to high pressure.
- The Outer Core is a liquid layer of the Earth, due to extremely high temperatures.
Plate Tectonics Theory
- The Plate Tectonics Theory states that the Earth's Lithosphere is divided into large moving plates.
- The plates move at an average rate of 15-20 inches per year.
- The process by which new land is formed through plate tectonics is the heated magma rising through cracks in the oceanic crust.
Key Characteristics of Plates
- The Earth's plates are described as moving in the Plate Tectonics Theory.
- New land is formed through volcanic eruptions, specifically by heated magma rising through cracks in the oceanic crust.
