Earth Science-8th Grade- Trimester 1

Earths Spheres:  4 Main Layers  Geosphere,Hydrosphere,Atmosphere,Biosphere

4 Main Layers of the Earth:                                        Crust,Mantle,OutterCore,InnerCore

Layers of the Atmosphere:                                   4 Main Layers  Troposphere,Stratosphere,Mesosphere,Thermosphere

Heat Transfer:                                                  Conduction, Convection,Radiation


Rock Cycle:                                                      SedimentaryRock,MetamorphicRock,IgneousRock  made by-Weathering&Erosion,Heat&Pressure,Melting&Cooling

Water Cycle:                                                    Precipitation,RunOff,Evaporation,Condensation          (Rain) - (GroundWater) - (WaterVapor) - (Clouds)

Solar Energy

3 Types of Electromagnetic waves                            InfraredRadiation,VisibleLight,UltraVioletRadiation

              ( Heat & Light)                                              (Harmful Cancer Causing Rays)

      

Wind-Cause by air pressure due to varying temperatures

Cold air sinks near the poles (high pressure) and warmer air near the equator rises (low pressure)

Air with more moisture which accumulates over the bodies of surface water, is also more dense than the atmosphere over land. 

Global Wind Patterns (above)

Ocean Currents- Cause by differing water densities due to varying temperatures

Waves-Caused by Wind



Temperature-the measurement of heat

Renewable&NonRenewable Resources- how fuels effect out environment

Soil-what it's made of and what its for


Ground Water vs Surface Water
