G e o g r a p h y Chapter 9: * 70% of the freshwater goes to the agricultural sector * If lakes dried up, temperature would rise * Lack of rainfall and increased evaporation can lead to drought * Dry soil, dry air, and high winds can cause wildfires * 9 of 10 wildfires are caused by humans, lightning is the largest natural cause Chapter 10: * 70% of the earth is covered in water * Water flows in rivers, it picks up small amounts of mineral salts from the rocks

cores (if we cut the ice into small pieces with the help of glaciers that was existed very long time ago and to see the trapped air bubbles in the ice); sediment analysis (based on the layers in the rock); and finally the tree rings (based on precipitation of rain or snowfall past years). So, based on the above several ways in which scientists can analyze the past climate in this planet. Apart

STRUCTURE OF THE ATMOSPHERE Troposphere | Closest to the earth and most weather happens here. Temperature drops as you go higher. Wind speeds increase. Most unstable layer. End of the sphere is marked by the tropoPAUSE- an isothermal layer where temp remains constant. | Stratosphere | Steady increase in temperature. Marked by the STRATOPAUSE. Atmosphere is thinner here. | Mesosphere | Temperature decreases to -90. No water vapour or dust to absorb radiation. Very strong winds at 3000 km/hr

Climate Change and How the Media Portrays It The average educated person would define climate change as the average weather changing or global warming. It is patterns of temperature, precipitation, humidity, wind and seasons. Climate is what makes up all natural ecosystems and is what helps sustain these ecosystems. The climate change today is changing the world. It’s affecting the natural ecosystems negatively. This is because climate is tied to almost everything. The change in climate will

Natalie Harshaw Mr. Royce Science Period 4 March 14th 2013 Reflection Essay During this unit I have learned a profuse amount of information about the earth we live on. Before this semester, I had not known even half of what I learned and I really enjoyed being educated on this subject. This semester was by far more entertaining and easier to follow than the last. What I learned over this course was the carbon and nitrogen cycle. I had barely even known what these were up until

that determine the long-term weather pattern in a particular area. In this experiment, the researchers investigated key climatic factors, namely: temperature, light intensity, relative humidity, wind speed, wind direction, atmospheric pressure, precipitation and rate of evaporation. The study sites of the investigators are located at the College of Medicine, Pedro Gil St., University of the Philippines Manila and were collected last November 19, 2010. The ecological significance and possible relationships

Clouds Jessica Pixley Weather and Climate Robert Morris University Clouds are an astonishing part of nature and help give us an idea of the current state of the weather. Clouds can vary dramatically in shape, size, color and position. Early in the nineteenth century French naturalist Jean-Baptitse Lamarck had started the first system to classify clouds which was polished by a naturalist named Luke Howard shortly after. Not until 1887 was Howards system finalized by Ralph Abercromby and Hugo

Q3 Impacts of climate change on Australian water resources The earth has a very perfect hydrologic cycle. It maintains water balance one the earth, promotes the prosperity of earth. However, the human activities in recent decades has largely disturb the hydrological cycle. Between 1990 and 2000, Australia lost an average of 325,900 hectares of forest per year. Australia has about 0.19% deforestation rate (mongabay, 2012). Due to the colonization and urbanization, in 200 years, Australia has lost
