Igneous Rocks


Igneous rocks form from magma in distinct ways and can be classified based on mineral composition and texture.
During this past week we have focused our discussion learning how igneous rocks are classified and how to interpret the chart on igneous rock identification (page 6 in the ESRT). This coming week, we will finish up igneous rocks and begin sedimentary rocks.


This Monday we will do one final exercise on Interpreting the Scheme on Igneous Rock Identification.
Homework: Due Monday, December 14, 2009

Complete all worksheets on igneous rocks.
Test on Minerals and Rocks this Friday, December 18, 2009

Rock Cycle

Image
The rock cycle is a model of the natural changes that occur in rocks and rock materials on the earth. The diagram to the right distinguishes between those processes that take primarily at Earth's (external processes) and those that take place within the Earth (internal processes).  Internal processes, such as compression and heating require the conditions of extreme temperature and pressure that occur deep within the Earth. The rock cycle illustrates several important principals of geology. First, nearly all rocks are made from the remains of other rocks (coal and other organic sedimentary rocks are important exceptions).  Second, rocks are classified on the basis of their origin.  Finally, there are a variety of ways that rocks can change in response to changing conditions at the surface or within Earth.

Weather Map Project

Image
In the past two weeks, we have been studying the properties of the atmosphere and the different weather variables. This week we will begin constructing weather maps.  We will also do a weather map project. The details are as follows: Project Due Date :  Friday, February 18, 2011 Task: Your assignment is to construct a weather map, for a seven day period, across the United States. Criteria : You may select the weather for a seven day period of your choosing. The project must be illustrated on poster paper and may include a typed report. The project must include the following items: o Title of Assignment o Two weather maps that track the changes in weather for the seven day period (from either newspaper or internet). o Map must include a general description of the weather patterns, for example, a description of air masses likely to create fronts (cP, continental polar, mT, marine tropical, etc.). o Indicate on map where unstable weather is occurring across the nation (precipitat

The Transportation of Weathered Materials

Image
Broken fragments of weathered rock are called sediments . These sediments are often carried or transported from their place of origin to another location. Erosion is the transportation of sediments most often done by water, wind and glaciers. The force of gravity drives most forms of erosion. For example, a weathered rock on a cliff is pulled by gravity, causing it to fall to the bottom of the cliff. Continued erosion, aided by wind and water, moves the sediment downslope away from the cliff. This week we will focus on the agents of erosion and in particular, the characteristics of a stream or river that affect its ability to erode sediment. Homework # 3 : Due Wednesday, February 25, 2009 Textbook: read pages 280-284. Review book: read pages 85-88; do questions 24-37.
