• Plate tectonics geology
• Major layer of the earth

  1.Crust

  2.Mantel

  3.Core
• Crust 


  The Earth's crust is the outermost layer of the Earth's surface, consisting of solid
• Mantle

  The mantle is the layer of the Earth located between the crust and the core, composed of hot, solid rock.
• Core: The Earth's core is the innermost layer of the planet, composed of a solid inner core and a liquid outer core.

  Inner core:The inner core is the solid, innermost layer of the Earth, primarily composed of iron and nickel.

  Lithos sphere:The lithosphere is the rigid outer layer of the Earth, consisting of the crust and the upper part of the mantle.
• Kind of crust

  1. Continental crust:The continental crust is the thicker, less dense outer layer of the Earth's surface, primarily composed of granitic rocks.
  2. Oceanic crust:Oceanic crust is the thinner and denser type of Earth's crust found beneath the oceans, primarily composed of basaltic rocks.

  7.Juan de fuca plate

  8.Caribbean plate
• Earthquake

  -An earthquake is a sudden and violent shaking of the ground caused by movements within the Earth's crust, leading to seismic waves and potential damage to structures and landscapes.
• Wave

  Waves are oscillations that carry energy through a medium or space, characterized by their amplitude, frequency, and wavelength.
• Wave (Secondary) waves -Secondary waves, also known as S-waves, are seismic waves that move through the Earth's interior, causing particles to move perpendicular to the wave's direction.
• Mantle- mostly solid, silicate (crust and core) Intermediate zone
• Lower mantle- is denser than upper mantle
• Upper mantle - Very thick layer of rock
