Module 1: Lesson 2. Characteristics of Earth that Sustain Life
Earth
"Planet of Life"
Thickness of atmosphere
100 miles
Biotic Factors
All the living organisms that inhabit an environment
Right Atmospheric Conditions
Capable of trapping heat and housing important gases.
Biogeochemical Cycle
Cycle by which chemicals circulate through an ecosystem using biotic and abiotic components.
Right Distance from the Sun
Earth is in Goldilocks Zone.
Greenhouse Gases
Gases in Earth's atmosphere that trap heat near the surface.
Goldilocks Zone
Habitable zone. A region with just right T not too cold and not too hot.
Geological Processes
Include volcanic eruptions, the formation and breakdown of rock, and major movements of matter within and below the surface of the earth.
Temperature of the Earth
Influence how quickly atoms and molecules move
Lithospheric Plates
Protects surface from the heat of the core.
Strong Magnetic Field
Shields us from electromagnetic radiation of the Sun. Deflects radiation that may destroy ozone layer.
Water
This matter dissolves and transports materials in and out of cell.
