Mineral Identification key link: 312ddf290c68329f/1_49838/media/e9c1ebb7042d73ddf26a167622f330f838cff957/76003.p df 7.02 Lab Introduction This activity will help you visualize some of the physical properties of soils. Specifically, you will investigate: 1. Texture: Texture relates the amounts of sand, silt, and clay-sized particles in a soil sample. Sandy soils are coarse-textured, and they feel gritty between your fingers. A soil made mostly of silt is medium-textured; it feels smooth like flour between your fingers. A clayey soil is fine-textured and it will feel sticky between your fingers.Most soils are a mixture of sand, silt, and clay and are a type of loam. Depending on where you live and the environmental conditions around you, your local soil may be sandy, silty, clayey, or loamy. 2. Color: Color is usually a result of the soil’s parent material, though it can also derive from local environmental conditions. Red, yellow and orange colors in a soil usually indicate the presence of iron. Grey colors are sometimes associated with soils that are water-saturated for much of the year. Soils very high in organic matter are usually dark brown or black. 3. Porosity and Permeability: Porosity describes the number of open spaces, or pores, between individual soil particles. Permeability describes how connected those pores are and how well water can move downward through the soil. A soil that drains water very quickly must have high porosity and permeability. On the other hand, a soil with very slow drainage (meaning that water has a hard time moving downward through it) will have low porosity and/or permeability. This is the link you can get the info from This is the sheet that needs to be filled out eba76faba45c31b0bb71/1_50582/media/622499fcd2b5d636ed84941af8f335134ff424 a9/81064.PDF This is the rubric for the lab eba76faba45c31b0bb71/media/37641e7b59aace9894a084d617224303c20938a4/712 17.PDF 7.03 Limiting factors-disc Limiting factors do not only affect soil fertility and crop production. There are common limiting factors to the growth of an individual organism as well as an entire population. Can you think of any limiting factors that may affect the growth of the human population of the United States? Post your thoughts to the Discussion: Limiting Factors link. Research Assignment: Desertification in the Sahel-7.03 • • • • Desertification is an extreme example of the problems associated with soil erosion. One of the regions where it is most problematic is the Sahel region of Africa. For this assignment, do some research on desertification in the Sahel. After your research, compile a research paper or a multimedia presentation to answer the following questions. Where is the Sahel located in Africa and how is it characterized in terms of climate and vegetation? Why is desertification taking place in the Sahel?

Please post your legend to the Discussion: River Legends Link: .htm Research Assignment: Rivers and Human Civilization-8.02 For this assignment, pretend you have been hired by a new museum to create a display on how rivers are important to human civilization. The museum wants you to create six separate galleries, each one with pictures and information about a different way that humans rely on rivers, or how human civilization and exploration has been affected by rivers. They also want a gallery dedicated just to displaying interesting facts about a certain river. 1. Select ONE of the rivers below and design six museum galleries for it: • Nile (Egypt) • Mississippi (America) • Amazon (South America) • Columbia (America) • Yangtze (China) • Volga (Europe) • Murray-Darling (Australia) • a river of your choice, such as one that runs through your hometown—you can go take your own pictures of it 2. Make a slideshow presentation to present the pictures and text you want in each gallery: • Have one slide for each gallery (a total of 6 slides): • four that show how the river is used by humans; • one that shows how the river has affected civilization, settlement, or exploration; • and one that shows a collection of interesting facts about the river. • Put the pictures in the main part of the slide. • In the Notes section beneath each slide, write text to describe the human need you are addressing and how the river provides or fulfills that need. Be sure to give examples and describe each one so that museum visitors understand how the river affects human civilization. Do not just say, "People use rivers for food." Give examples of foods we get from rivers, talk about how we get that food and how people use it, etc. After compiling your research, create your slideshow and submit your assignment to the Research Assignment:Rivers and Human Civilization assignment link for grading.

United States Limited Factors Threat

Institution Affiliation:



Limiting Factors that may affect the United States Human Population Growth.
Limiting factors are influences in the environment that dampers communities, organisms,
or populations productivity and thereby restrain them from their full biological potential
achievements realized only under optimal conditions. Ecologically, no society can grow minus
limitations. Population densities and growth can be influenced by many factors.
(Robert Paxton, 2017) Believes that overall growth of human population may also be
threatened by other humans. Vital resources such as food and water are the source of indirect
competition from a group of people who are habitats of the same region. The United States
human population continue to be threatened by warfare. For example, the threats coming from
the Islamic nations.
Dependent Density Limitation
Density-dependent factors include predation, disease, and competition. In the United
States, these factors can either have a positive or negative influence on the size of the population.
Hen the relationship is positive, the limiting factors increase with the population size, and as the
population size increases, they limit growth. On the other hand, when the relationship is
negative, there is low-density population limitation, and as it grows, it becomes less limited.
Migration and population mortality can also be affected by density-dependent factors. CluttonBrock et al. (2002) discovered the effect of density-dependent in a red deer population in a
highland within Scotland.



Density- Independent Limitation
(Sibley & Hone 2002) Defined population decrease factors as environmental stress that
includes, predation, food, and other density-dependent factors. Population in the United States
may be affected by these density-dependent factors such as climate extremes. Some of them
include monsoon, other catastrophic factors like hurricanes and fire.(Schindler, 1974)
demonstrated, using controls and whole-lake temperature, that phosphorus was the temperature’s
growth-limiting factor in North American lakes.
Catastrophes related to environments such as earthquakes, floods, volcanos, and fire can
affect the population growth strongly. This can happen through habitat destruction and mortality.
In 2005, for example, the coastal region of the Gulf of Mexico, southern United States was
impacted by hurricane Katrina altering coastal vegetation habitat as more than 5 centimeters of
sediment was deposited over the wetland zone. (Day et al. 2007) Nearly 100km of wetland got
destroyed, converted to open sea, erasing wetland vegetation. In 2010, there was Gulf oil spill
again impacting the coastal vegetation. This environmental disaster of high magnitude will
profoundly affect human population growth in the long term.
