CC: Hydrologic & Carbon Cycles Video Notes
1: What are Biogeochemical Cycles?
Biogeochemical cycles are pathways for molecules like water or elements like carbon, nitrogen and phosphorus to move through the Earth's ecological and geological departments.
2: What is a Reservoir of water?
A reservoir of water is some of the water on Earth being held. It can be held in the ocean, atmosphere (in the form of clouds) and in polar ice caps.
3: What is Precipitation? Name a few types:
Precipitation is when water in the atmosphere condenses. Some types are rain, hail, snow, sleet and more.
4: What is Evaporation? Where does most of evaporation take place on Earth? Sublimation? Deposition?
Evaporation is when a liquid converts into a gas. Sublimation is when a solid converts into a gas. Deposition is when a gas converts into a solid.
5: What is Condensation?
Condensation is when a gas turns into a liquid.
6: What is Runoff? Where does it ultimately end up? (Most of it)
Runoff is when water on the ground gets pulled towards the lowest point. Most of it normally ends up in the ocean.
7: Why are oceans salty?
Oceans are salty because water erodes salt and minerals and carries it to the ocean. When the water evaporates, the salt doesn't evaporate with it.
8: What are the 3 ways that the human body loses water?
The human body can lose water by exhaling water vapor, evaporating water from our skin, and we urinate it out.
9: What is evapotranspiration?
Evapotransportation is when water moves through the root of the plant and evaporates through the leaves.

Carbon Cycle
1: All living things require what to create their bodies?
All living things require carbon to create their bodies.
2: What percentage of the human body is Carbon?
30% of the human body is Carbon.
3: How are plants involved in the Carbon Cycle? What happens to the Carbon?- how does it get back to the environment?
Plants are involved in the Carbon Cycle by absorbing Carbon out of the atmosphere in order to photosynthesize. The Carbon is used druing the photosynthesis. It gets back in the environment by a plant's breathing process.
4: What happens to Carbon in the ocean? How does it get there? Where does it go?
Carbon in the ocean is used by the phytoplankton. It gets there by dissolving. It goes to the phytoplankton so they can photosynthesize.
5: What are shells made of? What happens when they fall to the bottom of the ocean?
Shells are made of calcium and carbon. When shells fall to the bottom of the ocean, they pile up and make limestone after a period of time.
6: What happens to Limestone when it is dissolved in water?
When Limestone dissolves in water, it creates carbon dioxide and carbonic acid.
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 Carbon in the atmosphere began to increase over time. It is important that some of the Carbon remains locked in the ground or ice because it would help the plants in colder places .
8: What is positive feedback loop? Hint: What is happening with global warming?
A positive feedback loop is when the dead plants in permafrost melts and creates carbon.
