Garbage If your habits resemble those of average Americans, you generate about 4.6 pounds of solid trash per day. This adds up to big trouble for the environment. Americans are generating waste products faster than nature can break them down and using up resources faster than they can be replaced. How can we find ways to meet our current economic and social needs without compromising the ability of our children, and our children's children, to do the same?
Biogeochemical cycles Biogeochemical cycles are pathways for the transport and transformation of matter within four categorical areas that make up planet Earth (biosphere, hydrosphere, lithosphere, and the atmosphere). Source. Biogeochemical cycles are components of the broader cycle that govern the functioning of planet Earth. The Earth is a system open to electromagnetic radiation from the sun and outer space, but is a virtually closed system with regard to matter. This means that the planet has minimal flux of matter, other than meteorite collisions and minor amounts of intergalactic particle trapping (or loss) by the upper atmosphere. Therefore, matter that Earth contained from the time of its birth is transformed and circulated geographically.
Weather New Englanders have a saying: "If you don't like the weather, just wait a minute." Weather forecasts may be more stable in other parts of the world, but the basic idea stands. Weather is dynamic, the product of interacting forces we are only beginning to understand. Witness the weather extremes caused by El Niño in 1997 and 1998. El Niño raised water temperatures in the Pacific and the effects were felt worldwide: crop failures, disease outbreaks, excess snow, or too little rain.
Your insight into science From the deep sea vents of the Cayman Trough to the shield volcanoes of the Hawaiian islands, Earth Scientists explore the structures and processes that define our world, the forces that continue to sculpt it, and how these processes have interacted over the last 4.6 billion years of Earths history. Our Earth science modules introduce how scientists use detailed observations, modeling, and comparative studies to develop their understanding of plate tectonics, the foundational theory of the Earth sciences, as well as biogeochemical cycles, the structure of the Earth and its atmosphere, and rocks and minerals. This module addresses the rock cycle, including the historical development of the concept. The relationships between uniformitarianism, the rock cycle, and plate tectonics are explored both generally and through the specific example of the Cascade Range in the Pacific Northwest. Powered by the sun, water constantly cycles through the Earth and its atmosphere.

Faculty of Science / Current students / Educational resources National Science Week posters National Science Week (NSW) is a countrywide celebration of science which aims to highlight the importance of science in people's daily lives. The theme for 2012 is"The Role of Science in Economic Development". This annual country-wide event is led by the Department of Science and Technology (DST), and supported by the South African Agency for Science and Technology Advancement (SAASTA). It is aimed at highlighting the important role science plays in everyday life and attracting the country's youth to enter and remain in science related studies and careers. The Science Faculty at UCT has for the last six years participated in NSW by producing high quality, scientifically up-to-date posters which are distributed to schools and used as a resource for teachers, learners and educators.
Earth Exploration Toolbook Awarded Science Magazine's Science Prize for Online Resources in Education (SPORE), September 30, 2011 AAAS Press Release What is the Earth Exploration Toolbook? Are You suprised ? Lesson Title: Making Solutions is Simple Objective: This lesson will focus on concepts in multiplication, division and will orient students to simple concepts in algebra and chemistry and biology Materials: Graduated cylinders 100 ml Food coloring A History of Climate Science Skeptical Science takes a different approach to Naomi Oreskes' Science paper who sorted her papers into "explicit endorsement of the consensus position", "rejection of the consensus position" and everything else (neutral). In this case, the backbone of our site is our list of climate myths. Whenever a climate link is added to our database, it is matched to any relevant climate myths. Therefore, each link is assigned "skeptic", "neutral" or "proAGW" whether it confirms or refutes the climate myth.
How Much Does a Gallon of Water Weigh? Oddly enough, I am often asked how much a gallon of water weighs. I’ve heard guesses anywhere from 5 pounds to 15 pounds. How much does a gallon of water really weigh? Climate Science Info Zone - There are many institutions and organisations around the world researching climate science, how our climate is changing, and ways of responding. Here are just a few… British Antarctic Survey (BAS) Department for the Environment, Food and Rural Affairs (Defra) Department of Energy and Climate Change (DECC) Energy Saving Trust (EST) Environmental Change Institute (ECI) European Space Agency (ESA) The Geological Society (GS) Grantham Institute for Climate Change (GICC) Intergovernmental Panel on Climate Change (IPCC) Met Office (MO) National Academy of Sciences (NAS) National Aeronautics and Space Administration (NASA) National Oceanic and Atmospheric Administration (NOAA) National Oceanography Centre (NOC) The Royal Society (RS) Tyndall Centre for Climate Change Research (TCCCR) UK Climate Impacts Programme (UKCIP) United Nations Framework Convention on Climate Change (UNFCCC) World Climate Research Programme (WCRP) World Meteorological Organization (WMO)
Dolores Gende: Environmental Science, Chapter 3 Fig. 3.10 The same principle of storage and release of potential energy applies to ecosystems. Matter, Energy and Life Fig. 3.1 From a biological point of view, the three most important gases of the lower atmosphere are nitrogen, oxygen, and carbon dioxide. Fig. 3.2 Water consists of molecules, each of which is formed by two hydrogen atoms bonded to an oxygen atom (H2O).
