Global Environment: Water, Air, And Geochemical Cycles, Second Edition.pdf

The Water and Energy Cycles and Atmospheric and Oceanic Circulation

The first chapter of the book introduces the global water cycle, which describes how water moves from the atmosphere to the land surface as rain or snow, infiltrates into the soil or runs off into streams and rivers, evaporates from lakes and oceans or transpires from plants back into the atmosphere. The water cycle is closely linked to the energy balance of the Earth, which determines how much solar radiation is absorbed or reflected by the Earth's surface and atmosphere, how much heat is emitted or trapped by greenhouse gases, and how much heat is transported by winds and ocean currents. The energy balance influences the temperature and pressure gradients that drive the atmospheric and oceanic circulation patterns that distribute heat and moisture around the globe. The book explains the basic principles of these physical processes and how they affect the climate and weather of different regions.

The Greenhouse Effect and the Ozone Hole

The second chapter of the book discusses some major global environmental problems that are related to air chemistry: the greenhouse effect and the ozone hole. The greenhouse effect refers to the phenomenon that some gases in the atmosphere (such as carbon dioxide, methane, nitrous oxide, and water vapor) absorb infrared radiation emitted by the Earth's surface and re-emit it back to the surface, causing a warming effect. The ozone hole refers to the depletion of ozone (a gas that absorbs harmful ultraviolet rays from the sun) in the stratosphere (the upper layer of the atmosphere) due to chemical reactions with chlorine and bromine atoms released by human-made substances such as chlorofluorocarbons (CFCs). The book explains how these phenomena are caused by human activities such as fossil fuel combustion, deforestation, agriculture, and industrial production. It also describes how they affect the climate system, the biosphere, and human health.

Rainwater, Acid Rain, and the Atmospheric Cycles of Sulfur and Nitrogen

such as dust, sea salt, pollen, and spores) or anthropogenic sources (such as power plants, factories, vehicles, and agriculture). Some of these substances can react with water to form acids, such as sulfuric acid and nitric acid, which lower the pH of rainwater and make it acidic. Acid rain can have negative impacts on soil, vegetation, aquatic life, buildings, and monuments. The book explains how the atmospheric cycles of sulfur and nitrogen are involved in the formation of acid rain and how human activities have altered these cycles and increased the acidity of rainwater in many regions of the world.

Chemical Weathering of Rocks

The fourth chapter of the book explains how rocks are broken down by chemical reactions with water, carbon dioxide, oxygen, and acids. This process is called chemical weathering and it affects the global carbon cycle and climate. Chemical weathering removes carbon dioxide from the atmosphere by converting it into bicarbonate ions that are carried by rivers to the oceans. This reduces the greenhouse effect and cools the Earth. Chemical weathering also releases other elements (such as calcium, magnesium, iron, and silicon) from rocks into the water cycle, where they participate in various biogeochemical processes. The book describes the major types of chemical weathering (such as dissolution, hydrolysis, oxidation, and hydration) and how they depend on factors such as rock type, climate, vegetation, and soil.

The Carbonate-Silicate Geochemical Cycle

The fifth chapter of the book presents a detailed account of how carbon dioxide is transferred between the atmosphere, oceans, rocks, and life forms. This is called the carbonate-silicate geochemical cycle and it regulates the long-term climate of the Earth. The cycle involves two main pathways: the carbonate pathway and the silicate pathway. The carbonate pathway involves the formation and dissolution of carbonate minerals (such as limestone and dolomite) and carbonate shells (produced by marine organisms such as corals and mollusks). The silicate pathway involves the weathering of silicate minerals (such as feldspar and quartz) and the formation of silicate rocks (such as basalt and granite). The book explains how these pathways balance each other over geological time scales and how they are affected by tectonic activity (such as volcanism and plate movements).

The Biogeochemistry of Lakes

and influenced by physical, chemical, and biological factors, and how they affect the global cycles of carbon, nitrogen, phosphorus, and other elements. Lakes are bodies of water that are surrounded by land and have a limited exchange with the external environment. They can be formed by various processes such as glacial erosion, tectonic movements, volcanic activity, river damming, and human construction. They can be classified by various criteria such as size, depth, shape, salinity, nutrient status, and productivity. Lakes are dynamic systems that undergo physical changes (such as stratification, mixing, and ice formation) and chemical changes (such as oxidation-reduction reactions, pH fluctuations, and nutrient cycling) depending on the season and the climate. Lakes also host a variety of biological communities (such as phytoplankton, zooplankton, bacteria, fungi, algae, macrophytes, fish, and birds) that interact with each other and with the physical and chemical environment. The book describes how these factors determine the biogeochemistry of lakes and how they influence the global fluxes of water, carbon dioxide, methane, nitrogen, phosphorus, and other elements.

Eutrophication of Lakes

(cloudiness), pH, alkalinity, hardness, and dissolved oxygen. The book explains how eutrophication can be measured, monitored, and modeled, and how it can be prevented or reversed by various management strategies such as nutrient reduction, biomanipulation, aeration, sediment removal, and chemical treatment.

The Biogeochemistry of Rivers

The eighth chapter of the book analyzes how rivers transport water, sediment, nutrients, organic matter, and pollutants from land to sea, and how they modify the chemical composition of seawater. Rivers are flowing systems that drain water from catchments or basins that cover various types of landforms and land uses. Rivers carry dissolved and particulate materials that originate from weathering of rocks, soil erosion, biological activity, and human activities. Rivers also exchange gases with the atmosphere such as carbon dioxide, oxygen, and methane. Rivers play a major role in the global cycles of water and geochemical elements by delivering large amounts of freshwater and solutes to the oceans. The book describes how the quantity and quality of river water and riverine fluxes are influenced by factors such as climate, geology, hydrology, vegetation, and human activities. It also discusses how rivers affect the salinity, alkalinity, acidity, nutrient status, and biological productivity of coastal waters.

The Global Phosphorus Cycle

for fertilizer production and use, sewage disposal, animal husbandry, and industrial processes. These activities have increased the phosphorus inputs to aquatic ecosystems, causing eutrophication and hypoxia (low oxygen) problems. The book explains how the global phosphorus cycle is quantified and modeled, and how it is affected by human perturbations and feedbacks.

The Biogeochemistry of Oceans

The tenth chapter of the book surveys how oceans are structured by temperature, salinity, density, and circulation, and how they interact with the atmosphere and the biosphere through various biogeochemical processes. Oceans cover about 71% of the Earth's surface and contain about 97% of the Earth's water. Oceans are stratified into layers that differ in their physical and chemical properties. The upper layer (the mixed layer) is well mixed by winds and waves and exchanges heat, gases, and water with the atmosphere. The intermediate layer (the thermocline) is characterized by a sharp decrease in temperature with depth and transports heat and salt by ocean currents. The deep layer (the abyssal layer) is cold, dense, and isolated from the surface except at high latitudes where it sinks due to cooling and salinization. Oceans are also divided into zones that differ in their biological productivity and diversity. The photic zone (the upper 200 m) is where sunlight penetrates and photosynthesis occurs. The aphotic zone (below 200 m) is where no sunlight reaches and chemosynthesis occurs. The benthic zone (the seafloor) is where sediments accumulate and benthic organisms live. Oceans play a crucial role in the global cycles of water and geochemical elements by absorbing, storing, transforming, and releasing various substances such as carbon dioxide, oxygen, nitrogen, phosphorus, sulfur, iron, and trace metals. The book describes how these processes are influenced by factors such as ocean circulation, biological activity, chemical reactions, sedimentation, and human activities.

Ocean Acidification

which forms carbonic acid and lowers the concentration of carbonate ions. Carbonate ions are needed by many marine organisms (such as corals, mollusks, echinoderms, and foraminifera) to build their shells and skeletons made of calcium carbonate. Ocean acidification reduces the availability of carbonate ions and makes it harder for these organisms to calcify and grow. Ocean acidification also affects other biological processes such as respiration, photosynthesis, nitrogen fixation, and nutrient uptake. Ocean acidification is expected to have negative impacts on marine ecosystems, biodiversity, fisheries, and aquaculture. The book explains how ocean acidification is measured, monitored, and projected, and how it can be mitigated by reducing carbon dioxide emissions and enhancing carbon sequestration.

Human Effects on the Global Environment
