Carbon Cycle
What is a carbon sink and name an example
ex. Photosynthesis
What part of the atmosphere do we live in?
The troposphere
Draw a water molecule and label the correct partial charges
H+ H+
O-
Where is the crust of the Earth located?
What is on the outside of the Earth?
Or
What is the part of the Earth we walk on?
What does the q stand for in the equation q=mcΔT
The energy it takes to heat a substance up (measured in joules)
What is a carbon source? Give an example.
A process that releases carbon.
Ex. Respiration (Breathing)
or Combustion (burning)
What important feature is located in the stratosphere and what does it do for us?
The ozone layer, it blocks out harmful UV rays
Cohesion
What is the semi-solid and thickest layer of the Earth?
The Mantle
How do you find ΔT
Subtract the lower degree from the higher degree
(ex. 100 - 50 = 50)
What historical event affected the carbon cycle?
The industrial revolution
What layer protects us from meteors
The mesosphere
The property where one molecule can stick to or interact with another molecule
Adhesion
What portion of Earth's layers is liquid?
The outer core
What does c represent in the equation q=mcΔT?
The specific heat index of a substance
(ex. water is 4.18)
How do greenhouse gases contribute to climate change
Greenhouse gases trap and absorb heat, thus making the atmosphere hotter
What happens to air pressure and density as you go higher in altitude? (further away from Earth's surface)
Air pressure and density decreases
What about water's structure allows for it to have the properties of cohesion, adhesion, and being the universal solvent?
It is a polar molecule
What Earth layer(s) give us our magnetic field?
The inner and outer core.
We want to warm up 100 grams of water from 100 C to 200 C. The specific heat index of water is 4.18. How much energy is needed for this?
41,800 J
q=mcΔT
q= (100g) (4.18) (200-100)
q= (418) (100)
q= 41800 J
Historically, what was fossil fuels for the carbon cycle? How has burning fossil fuels altered the carbon cycle?
Historically = carbon sink
Now that we burn them it is a carbon source
putting large amounts of carbon in the atmosphere that generally isn't there, can't naturally be taken out of the atmosphere
Draw and label a graph that shows how temperature changes as you increase in altitude and go through all the layers of the atmosphere
On Board
What does it mean to be a polar molecule?
There are SLIGHT differences in charge within ONE molecule
The inner core is the hottest part of the Earth but it is a solid, why?
Because the pressure is so high in the inner core that it is compacted into a solid
We see that it takes 9000 J to warm up water that has the specific heat of 4.18 from 58 C to 95 C. What is the mass of the water heated up?
58.2 g
q=mcΔT
q/cΔT=m
9000/ (4.18) (95-58) = m
9000/ (4.18) (37) = m
9000/ 154.66= m
58.2 = m
