Earths Spheres And Energy Interaction Flashcards
(6 cards)
1
Q
What are the four main Earth spheres involved in climate?
A
Atmosphere (air), Lithosphere (land), Hydrosphere (water), Biosphere (life).
2
Q
What is the atmosphere’s role in climate?
A
It traps heat via greenhouse gases, circulates air through convection, and supports weather.
3
Q
What is the hydrosphere’s role in climate?
A
It stores and redistributes heat via oceans, lakes, and ice through currents and phase changes.
4
Q
What is conduction?
A
The transfer of heat through direct contact between molecules (e.g., land surface to air).
5
Q
What is convection?
A
The movement of fluids (air or water) where warmer, less dense areas rise and cooler, denser areas sink.
6
Q
What is radiation (thermal)?
A
The emission of energy as electromagnetic waves, which does not require a medium.
