CHAPTER 2.2 Cycles of Matter
The Water Cycle 70% of the Earth s surface is water Oceans (97%) Rivers Lakes Underground reservoirs Atmosphere
The Water Cycle Evaporation The process during which liquid water changes into a gas called water vapor. 1. The Sun s energy 2. Temperature, wind, and humidity affect evaporation.
Condensation The process during which water vapor changes into liquid water. 1. Cooling of water vapor. 2. Clouds form due to condensation
Precipitation Water falls from clouds to Earth s surface. 1. Different forms: rain, snow, sleet, or hail
The Water Cycle - YouTube This video uses animation, graphics, and video clips to illustrate and explain each of the quot;flow ...
The Nitrogen Cycle Uses of Nitrogen(N2) 1. Essential part of proteins 2. An important part of DNA
1. Nitrogen gas is a form that plants and animals cannot use. Nitrogen Fixation The process that changes atmospheric nitrogen into nitrogen compounds that are usable by living things. bacteria - plants and decomposers

The Nitrogen Cycle | Chemistry for All | FuseSchool Nitrogen makes up 78% of the air, however neither plants nor animals can take nitrogen directly from the air because nitrogen is so unreactive. The nitrogen cycles shows the movement of nitrogen through the environment. Nitrogen is continually cycled through the air, soil and living things. Plants take up nitrogen compounds as nitrates from the soil. Animals then eat these plants, thus getting their nitrogen. The process of nitrogen in the atmosphere being turned into nitrogen in the soils is called fixing. There are different ways that nitrogen is 'fixed; including nitrogen fixing bacteria in the soil which turns nitrogen from the air into nitrates. Decomposers in the soils break down animal excretion and dead organisms, returning nitrogen back to the soil as ammonia. Lightning can cause chemical reactions in the atmosphere, resulting in nitrogen reacting with oxygen to produce nitrous oxide. Burning fossil fuels also adds nitrous oxide to the atmosphere, resulting in nitric acid, but this is of course not a natural way of nitrogen fixing. Blue-green algae in the ocean also can fix nitrogen. This then provides sources of nitrogen to aquatic animals, and the nitrogen goes around a similar cycle to what happens on land. The Haber Process makes up approximately 30% of nitrogen fixing. Denitrifying bacteria in the soil break down nitrates and return nitrogen back to the air. This reduces the fertility of the soil.

The Oxygen Cycle Importance of Oxygen 1. Cellular respiration 2. Composition water carbon dioxide sugar
1. Oxygen in the atmosphere is the result of many years of photosynthesis. 2. Oxygen cycles through the ecosystem. Takes on different forms. Used to make other elements.
Oxygen Cycle Useful for CBSE, ICSE, NCERT International Students Grade 09 Subject: Biology Lesson : Natural Resources Topic: THE OXYGEN CYCLE Oxygen-cycle is referred to as the cycle that maintains the levels of oxygen in the atmosphere. Plants and other producers use carbon dioxide in photosynthesis. They produce oxygen as a waste product. Carbon dioxide moves from the air into the leaves of plants.

The Carbon Cycle All organisms contain Carbon proteins sugars fats DNA All organisms get Carbon from food
Carbon in Soil Carbon enters the environment when organisms die and decompose. CO2gas Fossil Fuels
Carbon in Air CO2gas is released into the atmosphere During respiration.
The Carbon Cycle This professionally produced and narrated video describes the carbon cycle and why it is important, including an explanation of the Greenhouse Effect. It was produced for the Interactive Model of Leaf Decomposition (IMOLD) by the University of Toledo's Center for Creative Instruction in collaboration with Dr. Michael N. Weintraub and Dr. Daryl L. Moorhead, http://imold.utoledo.edu/
The Green House Effect CO2absorbs thermal energy from the Sun and keeps Earth warm. Greenhouse gases absorb thermal energy that reflects off Earth s surface. More gases, greater the gas layer and more thermal energy is absorbed
The Greenhouse Effect The temperature of earth has been relatively constant over time. This is possible because as the planet absorbs solar radiation, it also emits longwave radiation into space. Despite this radiative equilibrium, some longwave radiation remains trapped beneath the atmosphere of the earth and warms the surface of the earth. This phenomenon is called the "greenhouse effect."
