Introduction To Mineralogy And Petrology
B- Level the resources. C- Crash the project. D- Monte Carlo analysis. The answer is C, crash the project. Because, in first sentence, it is mentioned that schedule is too long, therefore the aim is making a shorter schedule. And in the second sentence it is mentioned that you have extra personnel resources. If you have resources, you can put more resources in an activity to complete it in a shorter time.

And this is actually a description of crashing an activity or crashing the project. If you look to the other options, fast tracking was performing activities in parallel instead of series, therefore it is irrelevant. Leveling the resources was for fixing the over-allocation of resources and distributing the tasks to all your resources uniformly. And Monte Carlo analysis was another estimating tool which is irrelevant choice as well. Therefore, here the best answer is C. The activity: A- Is on the critical path. B- Has a lag. C- Is progressing well. D- Is not on the critical path. Answer is D. And it gives 10 days of float for this activity. You will find the same result if you go through subtracting the early finish, 9 days, from the late finish, 19 days.

The National Association Of State Boards Of Geology( ASBOG) Examination:
Answer: C. The Sprint Retrospective is an opportunity for the Scrum Team to inspect itself and create a plan for improvements for the next Sprint. The goal of this activity is to inspect-and-adapt the process. First, the team goes over what they have done well. Then, they focus on what they did wrong or slow or how they could have done it better. Based on the discussions, improvement areas and actions are planned for the next Sprints. In the executing process group, you begin to become concerned about the accuracy of progress reports from the projects. What would BEST support your opinion that there is a problem? If you read the second sentence again, it says that you are concerned about the accuracy of progress reports from the project. In order to check whether the standards of your organization have been applied in the projects that you are responsible of, you can conduct a quality audit and find out whether there is really a problem.

Pyroxene is made up of single chains of tetrahedra while amphibole is made up of double chains. Some minerals have distinctive colours, but many have a wide range of colours due to differing impurities. Glass has a Mohs hardness of about 5. The mineral is between these two, so it must be close to 6. Chapter 3 The rock must be exposed at surface so in many cases uplift and removal of overlying sediments is required.

These fragments are sediments that can be eroded and then transported by a variety of maechanisms. Sediments are buried beneath other sediments where, because of the increased pressure, they become compacted and dewatered. Rock is buried within the crust and heated because of the geothermal gradient. As the temperature decreases minerals that formed early e. Calcium-rich plagioclase forms early on in the cooling process of a magma, but as the temperature drops, a more sodium-rich variety forms around the existing crystals.

Early-forming minerals, which are typically quite dense e. If the texture is aphanitic the crystals are too small to see without a microscope. In rocks with phaneritic textures the minerals are large enough to see and distinguish from each other with the naked eye. The dividing line is somewhere between 0. In porphyritic rocks there are two distinct crystal sizes that are indicative of two stages of cooling slow then fast. The fine material can range from glass to several mm, as long as the coarse crystals are distinctively larger.

In pegmatitic rocks the crystals are consistently coarser than 1 cm, and can be much larger. Pegmatites form the slow cooling of water-rich magmas. A concordant body a sill is parallel to any pre-existing layering bedding or foliation in the country rock is. A discordant body a dyke cuts across any pre-existing layering or is situated at any angle in country rock that has no layering e. A rock has to crack in order for a dyke to intrude into it, and it has to be cool to crack. When the hot magma intrudes into the cold country rock its margins cool quickly forming small crystals , while its centre cools more slowly forming larger crystals. A batholith has an exposed area of greater than km2; a stock has an exposed area less than that. Batholiths or stocks intrude into existing rock by a melting through the country rock, or b causing the country rock to break and fall into the magma stoping , or c pushing the country rock aside.

The primary mechanism for partial melting at a convergent plate boundary is the addition of water to hot mantle rock. The water reduces the melting temperature of the rock flux melting. The explosiveness of a volcanic eruption depends on the pressure of the magma. Gases create that pressure, and if the magma is viscous those gases cannot escape easily. Felsic and intermediate magmas tend to have more gas than mafic magmas, and are also more viscous, trapping the gas in.

Lahars are common on composite volcanoes because they are steeper than shield volcanoes, they typically have ice and snow, and they are not as strong as shield volcanoes. Some lahars form during an eruption when snow and ice melt quickly, while others may form from heavy rain. The magma at shield volcanoes is typically non-viscous. It can flow easily and also tends to form lava tubes, and thus is able to extend a long way from the vent, forming a low broad shield.

Shield volcanoes tend to have much longer lives than composite volcanoes. Most of the Hawaiian shields, for example lasted 1 million years, while most composite volcanoes are younger than , years. Weak seismic activity is associated with all stages of a volcanic eruption. In the early stages magma is moving at depth and pushing rock aside, creating small earthquakes. The flow of magma can also produce special type of seismic response known as harmonic tremor. GPS technology is used to determine if there is any slow deformation of the flanks of a volcano related to movement of magma toward the surface.

The Mt. Helens columnar basalts were formed by a flow of mafic lava. The Nazko Cone is thought to be related to a mantle plume. No one is certain why there a lower rate of volcanism in B. It is likely that carbon dioxide released during the eruption flowed downhill from the volcano to the village on the shore of the Nass River. Chapter 5 Before a rock can be exposed at surface it has to be uplifted from where it formed deep in the crust, and the material on top has to be eroded. Frost wedging is most effective at times when the weather swings between freezing at night and thawing during the day. In cold parts of B.

Under conditions of strong chemical weathering, feldspar albite NaAlSi3O8 will be converted to a clay such as kaolinite and sodium ions in solution. Where mechanical weathering is predominant, albite will be broken into small pieces. Acid rock drainage ARD creates acidic stream runoff and also enhances the solubility of a wide range of metals, some of which can be toxic. Feldspar-rich sand is formed in areas where granitic rocks are being weathered and where mechanical weathering is strongly predominant over chemical weathering. Most of the clay that forms during hydrolysis of silicate minerals ends up in rivers and is washed out to the oceans. There it eventually settles to the sea floor. The mineral composition of the parent rock or sediment will influence the composition of the resulting soil. Slope is important because it will affect the degree to which materials will be eroded. Clay minerals and iron move downward to produce the B horizon of a soil. Removal of vegetation leaves soil exposed to erosion by water, and wind are the main processes of soil erosion in Canada.

Graded bedding Mud cracks form where fine-grained silt or clay sediments are allowed to dry because the level of a lake decreases. Reverse graded bedding forms during gravity flows, such as debris flows. A formation is a series of beds that is distinct from other beds above and below it, and is thick enough to be shown on the geological maps that are widely used within the area in question.

Heat leads to mineralogical changes in the rock. Pressure also influences those mineralogical changes, while directed pressure greater pressure in one direction leads to foliation. At very low, low, medium, and high metamorphic grades, mudrock will be transformed into slate, phyllite, schist, and gneiss. Granite remains largely unchanged at lower metamorphic grades because its minerals are still stable at those lower temperatures. Foliation exists because as new minerals are forming in a situation of directed pressure they are forced to grow with their long axes perpendicular to the main pressure direction. At a spreading ridge the heat from volcanism leads to the development of a groundwater convection system in the oceanic crustal rock. Heated water rises in the hot regions and is expelled into the ocean, while cold ocean water is drawn into the crust to replace it.

The heated water leads to the conversion of ferromagnesian minerals e. The geothermal gradient varies as a function of tectonic setting, being greatest in volcanic regions and lowest along subduction zones. As a result the depth at which specific metamorphic grades is achieved will vary greater depth where the gradient is least. The geothermal gradient is low within subduction zones because the cold subducting oceanic crust takes a long time to heat up , so while pressure increases at the normal rate the temperature does not.
