Mr. Longoria's Earth Science

The winter Regents week is over. We begin our second semester on February 2, 2010 (groundhog's day). Now, we begin our Spring semester (even though Winter has a deep hold on us still) and our work on plate tectonics continues. We will revisit the types of plate boundaries and analyze and evaluate how each of the three main types interact with each other. In other words, we will look at the processes involved, the characteristic features of each boundary, and what influences the movement of these plates. We will start analyzing the types of plate boundaries and plate motions that caused the Haiti earthquake by next week. Homework #1: Due Friday, February 5, 2010 Textbook : read chapter 8.2, pages 176-179; do questions 1-7, page 179.

A topographic or contour map shows the shape of the Earth. The contour lines connect points of the same elevation. This week we will focus on how to analyze and interpret a contour map. We will also construct topographic profiles or cross sections of mapped terrains. Topographic maps include information about the three dimension length, width, and height of a region. A profile shows the elevation of the land along a particular baseline. Homework # 6 , Due Wednesday, November 4, 2009 Complete the topographic map worksheet that will be distributed on Monday, November 2.

Topographic maps can be used to determine the shape of the land, the direction of the flow of streams, and distance. To determine the shape of the land, we draw a line across the map. Wherever a line meets a contour, the exact height above sea level can be determined. Plotting those points on a vertical scale results in a profile (cross-section) of the land. Homework : Due Wednesday, 12 November 2008 In text, reread pages 53- 57. Go to the section on published assignments or to the following link, contour line exercise , print a copy and complete the assignment. Kaaterskill Clove Assignment Take a look at the topographic map of Kaaterskill Clove, NY, found above. Find the stream near the southeast edge of South Mountain. Answer the following questions: What is the map's contour interval? What are the contour lines doing when they cross the stream? In what direction is the stream flowing? Calculate the average gradient of the terrain along the stream. The scale of the map is 1:62500...

Quiz: Monday, November 3, 2008 (Solar time and time zones). This week, we will begin the study of topographic maps and contour lines. Topographic maps are one of the most used maps in earth science and geology, which depicts the surface features of an area through the use of contour lines. Homework: In textbook , read chapter 3.3, pages 53-57 and do section review questions 1-6, on page 57. Due Wednesday, Nov. 5, 2008. En Español En el texto , Lean el capitulo 3.3, paginas 53-57.

This week we will continue with our work on solar time and longitudinal positions on the surface of the earth. We will also begin to discuss our understanding of Earth as a sphere and those responsible for our understanding. In particular we will discuss individuals such as Eratosthenes. Eratosthenes of Cyrene ( 276 BC - 194 BC) was a Greek mathematician, poet, athlete, geographer and astronomer . He made several discoveries and inventions including a system of latitude and longitude . He was the first person to calculate the circumference of the Earth (with remarkable accuracy). Homework : Due Wednesday, 29 October 2008 Complete the worksheet "Measuring the Circumference of a Sphere" by going to the link listed below under published assignments. In Reviewing Earth Science (Review Book), do questions 25-27, on page 20. Quiz: Friday, 31 October (Happy Halloween) Prueba: viernes, 31 de Octubre Topics : Solar Time and Longitude circumference of a sphere

Cyclone Nargis was a strong tropical cyclone that developed in the Bay of Bengal about 360 miles off of the southeast coast of India on April 27, 2008. Landfall occurred in the Ayeyarwady Division of Myanmar. Strong winds of over 120 miles per hour, heavy rain, local flooding and a storm surge resulted in a death toll expected to exceed 100,000 with over 2,000,000 people left homeless and without water, power, food or sanitary conditions. It might be the deadliest cyclone of all time. This week we will learn how severe storms such as huricanes form and what factors determine how fast winds blow during these storms. Homework : Due Friday, May 23, 2008 In textbook: read chapter 20.4, pages 450-453. Do Section Review questions 1-3. In review book: read pages 176-178. Do questions 13-20.

This week, we will examine how glaciers form, move and reshape Earth's surface through erosion and deposition. About 75% of Earth's fresh water is frozen in glaciers. Glaciers form in areas that are always covered by snow. As a result, layers of snow build up from previous years and form large masses of compacted snow and ice that move under the force of gravity. Satellite view of Greenland ice sheet Homework : Due Thursday, March 21, 2008 Students using the McDougal Littell textbook , read pages 318-320. Do questions 1-5 on page 320. Students using the Heath Textbook , read pages 191-195. Do questions 1-5 on page 195. Quiz scheduled for Thursday, March 21, 2008.
