What is the definition of a series circuit
A circuit where components are connected in a single path, so the same current flows through all components.
What does thermohaline circulation do
create variations in density, causing water to sink in colder, saltier regions and rise in warmer, less salty areas
what is the greenhouse effect
Certain gases in the atmosphere absorb energy, slowing or preventing the loss of heat to space
What happens if you add more components to a series circuit
How do ocean currents help the redistribution of heat on Earth
Ocean currents help redistribute heat on Earth by moving warm water from the equator toward the poles and bringing cooler water from the poles back to the equator
What are some of Earth's molecules that absorb some of the infrared radiation
H2O, CO2, CH4, and O3
How does the behavior of current and voltage differ in series versus parallel configurations
The current gets split in the parallel so that each component can have the same voltage but the current in the series keeps going and decreases in power leading to the components losing voltage
What causes the difference in solar energy received at the equator compared to the poles?
The equator receives more solar energy than the poles because sunlight hits directly at the equator, while at the poles, it arrives at a slant, travels through more atmosphere, and is reflected by ice and snow
what temperature would the Earth be without the greenhouse effect
-18oC (0oF)
How does the voltage across each component in a parallel circuit compare to the total voltage?
The voltage across each component is equal to the total voltage
What is thermohaline circulation
Thermohaline circulation is a deep ocean current system driven by differences in water temperature and salinity
When was the greenhouse effect discovered
1859
If a series circuit has a total voltage of 12V and two identical light bulbs, what is the voltage across each bulb?
6V
Why is the transfer of energy from the equator to the poles important for Earth's climate system
The transfer of energy from the equator to the poles is important for Earth's climate system because it helps regulate temperatures, influences weather patterns, and maintains ecosystems
Explain the mechanism of the greenhouse effect
The incoming solar energy from the sun is redirected back towards space by the atmosphere and clouds and then some of the solar energy gets absorbed by the atmosphere and clouds. And the remaining energy gets absorbed by the Earth's surface making it warm
