(BQ) Lecture Engineering geology - Chapter 8: Rock mechanics. After completing this section, you will understand the knowledge about Material of the Earth’s crust, composed of one or more minerals strongly bonded together that are so little altered by weathering that the fabric and the majority of the parent minerals are still present.

this volume is designed to accommodate a broad interpretation of the term environmental studies, and to do so incorporates material from a wide range of disciplines. the interdisciplinary nature of environmental issues necessitates the inclusion of topics from physical sciences such as chemistry, physics, geology and biology alongside entries from atmospheric, engineering, earth and soil sciences. since current environmental issues include a strong human element, entries from geography, demography, politics and economics also have their place.

Soils are aggregates of mineral particles, and together with air and/or water in the void spaces, they form three-phase systems. A large portion of the earth’s surface is covered by soils, and they are widely used as construction and foundation materials. Soil mechanics is the branch of engineering that deals with the engineering properties of soils and their behavior under stress.

Optical fibers, an important and promising material, have been the subject of intensive research and development due to their many scientific and practical applications. They are designed to guide light along its length by confining as much light as possible in its core. The interaction between the propagating light with the fiber material is the foundation of the development of various applications such as optical amplifiers, fiber lasers, sensors etc.

In the early years of oil drilling and production, wells were primarily drilled on land to moder- ate depths and with relatively minor horizontal offsets, and an empirical understanding of the impact of geological forces and Earth material properties on required drilling practice was de- veloped by region. Successful practices were defined by trial and (sometimes costly and spectacular) error.

Many of the Earth’s elements travel or cycle through the natural environment. This means that they are transported from the soil into nearby lakes and rivers, and then evaporate from the water into the air, to be transported by wind and eventually re-deposited to the surface where the cycle starts over again. Mercury cycles through the environment in this way (see Figure 5). An atom of mercury may begin its journey by being eroded from rocks on the shore of a lake or by being vented into the atmosphere as mercury vapour from a volcanic eruption. These are natural emissions.

The atmosphere is the layer of air surrounding the earth and its structure below 50 km is most important in determining pollution levels. In this sense, greenhouse effect and climate change are evoking a special interest recently since they are considered to be human hazards. Greenhouse effect is produced by infrared radiations, imprisoned between the earth and the thin layer of greenhouse gases, which get reflected and heat up the earth’s surface.

Why is it important to study Hydrodynamics? The answer may be strictly technical, but it may also involve some kind of human feeling about our environment and our (eventual) limitations to deal with its fluidic constituents. As teachers, when talking to our students about the importance of quantifying fluids, we (authors) go to the blackboard and draw, in blue color, a small circumference in the center of the board, and add the obvious name 'Earth'.

Generally, biomass is used for all materials originating from photosynthesis. In other words, biomass includes all plant growth, herbaceous plants, microalgae, macroalgae and aquatic plants. But biomass can equally apply to animal as well. In fact, biomass is carbon based and is composed of a mixture of organic molecules containing hydrogen, usually including atoms of oxygen, often nitrogen and also small quantities of other atoms, including alkali, alkaline earth and heavy metals.

Global change, including climate change, ecosystem shifts and biodiversity loss as a result of explosive human population growth and consumption, is emerging as one of the most important issues of our time (Vitousek, 1994). Climate change in particular appears to be altering the function, structure and stability of the Earth’s ecosystems (Lovelock, 2009). It has been marked by an 80% increase in atmospheric CO2 level and a 0.

Anthropogenic air pollution constitutes of many substances. Greenhouse gases absorb and reflect some of the infrared parts of solar radiation reflected from the earth surface thus causing the troposphere to be warmer. Among others, these substances are carbone-dioxide, water vapour, hydrogen oxides, nitrogen-oxides and methane. Beyond causing warming, most of these gases are poisonous to the Earth’s biosphere. Besides greenhouse gases, there are a few more poisonous substances which have anthropogenic sources.
