Earth as a System

What is Earth Science?

What are the Earth System’s four Spheres?

What are cycles and how do they work?Slide2

System: A kind of model often used to describe the natural world.Closed System: ENERGY enters and may leave, but MATTER does not leave

Open System

: ENERGY and MATTER are free to enter and leave

Is the Earth an Open or Closed System?Slide3

Earth is considered closed, there are a few exceptions: hydrogen escapes & meterorites


VolcanoEnergy is released, matter released as lavaLight bulb

Electrical Energy enters, light is released


Sunlight, water, & Carbon Dioxide in, water and oxygen released, seeds and leaves drop to ground


Sunlight enters, water enters through runoff and precipitation, water leaves through evaporation

Boiling WaterHeat enters, heat and vapors are released



Science helps educate us and find solutions!!!

Humans and the planet EarthSlide6



gaseous envelope surrounding the Earth.

Provides Oxygen & Carbon Dioxide, also absorbs and blocks harmful radiation. Where all weather occurs.


: all physical features of the Earth (except water) such as rocks, mineral resources, metals, mountains, beaches, and lithospheric



Includes all of Earth’s water including oceans, rivers, lakes, and groundwater, it is continually recycled. 97% salt water, 3% fresh water, 1% usable.


All living things

Discuss interactions among the Spheres

The Earth System’s four SpheresSlide8

Identify the 4 SpheresSlide9

Carbon CycleSlide11

Carbon in our EarthSlide12

The movement of Energy into and out of the Earth SystemA.K.A. The Energy BudgetBalance

is the Key

: equal energy in and out

The Energy CycleSlide13

Solar Energy


of total energy

It comes from nuclear reactions in the sun
