Study Notes

Earth's Layers

  • The inner core is composed of solid iron and nickel.
  • The thickest layer of the Earth is the mantle, which is divided into the upper mantle and lower mantle.

Mantle

  • The mantle is predominantly made up of solid rock and minerals.

Core

  • Convection of molten iron and nickel occurs in the outer core.
  • The outer core is responsible for generating the planet's magnetic field.

Mantle Convection

  • The primary reason for convection currents in the mantle is the heat from the Earth's core.
  • The lower mantle experiences the most pressure due to the weight of the overlying rock.

Plate Tectonics

  • The convection currents in the mantle cause the lithosphere to move, creating phenomena such as earthquakes and volcanic eruptions.

Water Cycle

  • The term that describes the continuous movement and circulation of water on, above, and below the surface of the Earth is the water cycle.
  • Evaporation involves the conversion of water from liquid to vapor, mainly from the surfaces of water bodies.
  • Condensation is the process where water vapor changes into liquid water, forming clouds in the atmosphere.
  • Precipitation is the phenomenon that involves the return of water to the Earth's surface in the form of rain, snow, sleet, or hail.
