Week+Sixteen

Week Sixteen Assignments

This week your assignment is to read chapter 13 Introduction to Landform study. You will find the supplemental material posted here: http://schmidtphysicalgeography.wikispaces.com/Ch+13 There is a Prezi for this chapter, and there is also a lot of supplemental material on the chapter page. I think I have actually embedded it all into the Prezi for this chapter - except for the last articles on the bottom of the page which are more recent. Below is your vocabulary assignment, and at the bottom of this page is a posting assignment. You have a quiz on Blackboard for this chapter too. For your writing/posting assignment this week, I thought we would try something a little more creative. I think there are a lot of interesting things in this chapter and I bet each of you have something in this chapter that fascinates you. I look forward to reading your posts : ) Also, I wanted to let you all know that I really appreciated your posts about your favorite forests.

1 asthenosphere Plastic layer of the upper mantle that underlies the lithosphere. Its rocks dense, but very hot and therefore weak and easily deformed. --Gilda Rodrigues 2 basalt- Basalt is a common mafic extrusive volcanic rock. It is usually gray to black and fine-grained due to rapid cooling of lava at the surface of a planet. It may be porphyritic containing larger crystals in a fine matrix, or vesicular, or frothy scoria. Unweathered basalt is black or gray. -Sara Sanchez 3 contact metamorphism~ ====Is the metamorphism of surrounding rocks by contact with magma~ It can happen underground or at the earth's surface. When it happens underground hot magma fills areas within the crust, large areas filled with magma are called batholiths. The area around the batholith is called an aureole. When magma (lava) is erupting above ground from a volcano it also alters the rock that it touches.==== Karen Villalpando



4 continental drift -Leticia Villasenor
 * Continental drift- ** is the movement of the Earth's continents relative to each other, thus appearing to "drift" across the ocean bed. The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596.

5 CRUST: The outermost solid shell, or layer, of a rocky planet, which is chemically distinct from the underlying mantle.

-Sahlah Storks.

6 external (geomorphic) processes 7 geomorphology- The study of the characteristics, origin and development of landforms. -Andrea Anguiano 8 granite- Most well known plutonic rock because it is the most common. It is light salt and pepper colored coarse grained igneous rock who dominate material is high- silica felsic magma. -Vanessa Loera 9 halides-Paul Garcia  The Halides are a group of minerals whose principle chemical constituents are fluorine, chlorine, iodine, and bromine. Many of them are very soluble in water. Halides also tend to have a highly ordered molecular structure and a high degree of symmetry. The most well-known mineral of this group is halite (NaCl) or rock salt.

10 igneous rock Some of the better-known kinds of igneous rock that comes from volcanoes are pumice, lava, and obsidian. When lava cools, it often turns into basalt. Other igneous rocks formed slowly, deep in the earth. Some examples are quartz and granite. _Arianna Fulton 11 inner core- Monica Gonzalez The Earth's **inner core ** is the Earth's innermost part and according to seismological studies, it is primarily a solid ball with a radius of about 1220 kilometers, or 760 miles (about 70% of the Moon's radius). 12 internal (geomorphic) processes

13 landform- Lidia Quintanilla ==== A landform is a feature on the Earth's surface that is part of the terrain. Mountains, hills, plateaus, and plains are the four major types of landforms. Minor landforms include buttes, canyons, valleys, and basins. ====



14 lava- Is molten rock flowing out or is squeezed up onto the surface, during a volcano eruption. -Angel Ojeda

15 lithosphere - Reina Garcia Is the solid outer section of Earth, which includes Earth's crust (the "skin" of rock on the outer layer of planet Earth), as well as the underlying cool, dense, and rigid upper part of the upper mantle.

17 mantle
 * 16 magma - is a mixture of molten or semi-molten rock, volatiles and solids[1] that is found beneath the surface of the Earth, and is expected to exist on other terrestrial planets. (By Lindsey Skaggs)**

18 metamorphic rock Metamorphic rocks are rocks that have been changed from their original state by either high pressure or very high heat. The process can be either a physical, or chemical change. Cesar Melendez

19 mineral
 * //A mineral is an element or chemical compound that is normally crystalline and that has been formed as a result of geological processes //**




 * //-Faraz Abbasi //**

20 Mohoroviˇci´c discontinuity (Moho) 21 native elements- Native element minerals are those elements that occur in nature in uncombined form with a distinct mineral structure. The elemental class includes metals and intermetallic elements, naturally occurring alloys, semi-metals and non-metals. -Christina Camarena 22 outcrop (

24 oxides

An ** oxide ** is a [|c] hemical compound that contains at least one oxygen atom and one other element in its [|c] hemical formula.

25 plutonic (intrusive) igneous rock 26 pyroclastics --Barbara Ciaravino Pyroclastics are composed chiefly of rock fragments of explosive origin, especially those associated with explosive volcanic eruptions. Volcanic ash, obsidian, and pumice are examples of pyroclastic materials.

27 relief 28 rock- a rock or stone is a naturally occurring solid aggregate of one or more minerals or mineraloids. For example, the common rock granite is a combination of the quartz, feldpar and biotite minerals. The Earth's outer solid layer, the lithosphere, is made of rock

29 Rock Cycle - The ** rock cycle ** is a basic concept in geology that describes the dynamic transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous. 30 sedimentary rock -Jessica Quintanilla

Sedimentary rocks are formed by the accumulation of sediments. There are three basic types of sedimentary rocks. Clastic sedimentary rock, which is a rock made up of rock fragments that have been moved by water, wind or ice. Chemical sedimentary rocks, which are formed from minerals that precipitated from water, and the last is organic sedimentary rock, which form from the remains of organisms.



31 silicate (silicate minerals) 32 strata - Lucinda Crespin

Strata is made of up sedimentary deposits in distinct horizontal layers which vary in thickness and composition. Strata can be uplifted tilted and deformed by pressures within the earth. In some areas, fossil remains can be found between layers of strata. Strata can also be used to determine the dates of geological events that have been preserved in the rock record (layers of strata). In the photograph below, human fossils found in strata. Dinasour bones were also found in this layer of strata that had human fossils.
