Crash Course: Hydrologic and Carbonic Cycles
Crash Course: Hydrologic and Carbon Cycles Guided Viewing Worksheet
1: What are Biogeochemical Cycles?
Biogeochemical cycles are pathways for molecules like water, and elements like carbon, nitrogen and phosphorous to move through all of Earth's environment and various ecosystems.
2: What is a Reservoir of water?
A reservoir of water is a large, usually man-made body of water molecules.
3: What is Precipitation? Name a few types:
Precipitation is any form of water forming a liquid from a gas and falling to earth (rain, hail, snow, etc.)
4: What is Evaporation? Where does most of evaporation take place on Earth?
Evaporation is when water goes from a liquid to a gas, like when you boil water (steam).
Sublimation?
When water goes from a solid straight to a as, skipping the liquid form (solid C02 or "dry ice")
Deposition?
Basically the opposite of sublimation, deposition is also known as desublimation, and happens when a gas is super-condensed into a solid, skipping the liquid phase.
5: What is Condensation?
When water gets cold and goes from a gas to a liquid (cold glasses of liquid). This happens because of the pressure differences.
6: What is Runoff? Where does it ultimately end up? (Most of it)
Any carrying of minerals or things by water on land or via streams/rivers, usually from a higher elevation to a lower one. Most of it ends up in the OCEAN.
7: Why are oceans salty?
As water runs to the ocean, it carries minerals like salt, which, even after the water that carried it evaporates, stays behind.
8: What are the 3 ways that the human body loses water?
The three ways that the human body loses water by:
Evapotranspiration is the sum of the total water evaporated from the surface of the water, plus the total of water released through transpiration, which is like plants sweating. ?.

The Carbon Cycle
1: All living things require what to create their bodies?
CARBON!!!
2: What percentage of the human body is Carbon?
18%
3: How are plants involved in the Carbon Cycle? What happens to the Carbon?
Plants, through photosynthesis, consume carbon (as c02) and "breathe out" oxygen. The carbon is released again when the plant dies.
4: What happens to Carbon in the ocean? How does it get there? Where does it go?
The carbon in the ocean mainly gets there by c02 in the air, via large factories and emissions, but also from plants, and animals like ourselves. It dissolves into the ocean water, making it more acidic.
5: What are shells made of? What happens when they fall to the bottom of the ocean?
Most shells are made of carbonic ions and calcium, when they fall to the sea floor, they compress and form limestone.
6: What happens to Limestone when it is dissolved in water?
Limestone, when dissolved in water, breaks down. It will break down faster if the water is more acidic.
7: What is happening with the excess Carbon in the atmosphere? Why is it important that some
of the Carbon remains locked in the ground or in ice (glaciers, permafrost)?
The excess carbon in the atmosphere gets dissolved into ocean water. The more c02 in the water, the worse it is for marine life.
8: What is positive feedback loop? Hint: What is happening with global warming?
A positive feedback loop is a loop in which things are fed back positively.

8: What are the 3 ways that the human body loses water?
The three ways that the human body loses water by:
- Sweat through our skin
- Exhaling while breathing
- Urinating
