Chapter 3: Soil And The Geosphere Flashcards
(47 cards)
Matter
Anything that has mass and takes up space.
Define System and Name Components
Components that function and interact in some regular and theoretically understandable manner.
High Quality Matter
Matter with a lot of usable energy, is concentrated, and found near the Earth’s surface.
Low Quality Matter
Dilute matter with low potential to be used as a resource.
Law of Conservation of Matter
Matter can neither be created or destroyed. Matter only changes form.
First Law of Thermodynamics
Energy can neither be created or destroyed, only changes form.
Second Law of Thermodynamics
When energy changes form, the energy usability decreases.
Kinetic Energy
Energy in motion
Potential Energy
Stored Energy
Elecrtromagnetic Radiation
Waves, and light.
Convection
Circulation of heat from source at the bottom.
Conduction
Heat is transported from the solid.
Radiation
Heat is emitted out wards from the solid.
What is kind of system is sunlight?
Open System
What kind of system is the recycling of water and nutrients on earth?
Closed System
Positive Feedback
Continuous system that moves forward.
Negative Feedback
Causes system to change direction.
Low-Throughput Economy
Economy with a recycling system that conserves waste and pollution.
High-Throughput Economy
Economy which uses a lot of energy, which leads to waste and pollution.
How are CO2 and temperature related?
They are directly related, so as CO2 rises, temperature rises.
How old is the Earth?
4.5 Billion years old
Pangea
Supercontinent which was formed due to tectonic plate movements.
Name layers of the Earth.
Crust, Lithosphere, Asthenosphere, Mantle, Outer Core, and Inner Core.
Convection in Plate Tectonics
The convection currents in the asthenosphere caused plate movements.
