Carbon cycle
Can Humans disrupt the natural carbon cycle? Give an example
Depends on what students say: fertilizer, burning fossil fuels. etc
What is nitrogen fixation?
Nitrogen gas is being converted into ammonia. This is done by bacteria that live in the soil or in the roots of specific plants known as legumes (peas or beans).
Higher ocean temperatures lead to increased evaporation, which forms more clouds that reflect sunlight and lower global temperatures.
Negative Feedback Loop-Because the process works to reduce the initial change (lowering temperatures in response to warming), it acts as a stabilizing force.

What is air pressure? Can we feel it, and why not?
Air pressure is the force exerted by the weight of the atmosphere on all objects on Earth's surface. No, we can't feel it. Our bodies pressure equals it out.
Which of the following contain carbon molecules: Diamonds, Limestone, Graphite, Coal, Green leaves, And all living organisms.
All of them!
The process by which plants, fungi, and bacteria absorb inorganic nitrogen (nitrates, ammonia) from their environment and convert it into organic compounds like amino acids, proteins, and DNA.
Assimilation
What type of feedback is sweating?
Negative feedback.
What happens to the molecules when mountaineers go up in elevation
There is less Molecules, they spread out - thinning of oxygen.
What are the two factors that affect air pressure...
Temperature and Altitude
Carbon and nitrogen are essential for life because they are
building blocks of DNA and proteins
What is the final stage of the nitrogen cycle that turns ammonia and nitrates back into atmospheric (gas) nitrogen?
Dentrification.
Increased atmospheric carbon dioxide leads to higher global temperatures, which results in more carbon dioxide being released from natural sources. Positiveor negative
Positive- feedback loop. Increased warms the atmosphere, which triggers natural systems (like melting permafrost or warming oceans) to release even more amplifying the initial warming effect.
A Barometer is used for what...
to measure air pressure
Describe a low-pressure system..
Warm air is less dense than cool air because the molecules move faster and spread out when heated, causing warm air to rise and creating areas of low pressure.
What process changes dead organisms into fossil fuels? Provide a temporal scale.
Decomposition.- Millions of years
What happens to nitrogen when something dies?
It gets carried away and cycles throughout the rest of the Earth's reservoirs.
Is our current climate system an example of positive feedback?
YES
When is my son's birthday?
March 19th TODAY!
What is the difference between a high-pressure system and a low-pressure system?
Cool air is denser and sinks
What are the main reservoirs for carbon?
Living organism, atmosphere, ocean and land
This process often causes dense algal blooms that deplete oxygen in water, resulting in fish kills and degraded water quality. It can occur naturally over centuries or rapidly through "human activities" like fertilizer runoff and sewage discharge.
Eutrophication-
Why is negative feedback helpful in a system?
It helps to regulate and stabilize a system.
When will the school show Mamma Mia?
Next Week- Thursday and Friday March 27,28th
What happens when global temperatures increase? Will air pressure be affected?
Depending on students' response, global warming- warmer temps- less dense, causing warm air to rise and creating areas of low pressure- more rain and storms!
