- Briefly describe the structural differences between hematite and goethite. Why does climate affect the relative amounts of these two minerals in soils? (5 pts)
Homework Answers
Hematite and geothite are different types of iron ores.
Hematite is essentially iron(III) oxide with a formula Fe2O3 and exhibiting a trigonal crystal structure.
Geothite has a formula FeOOH and exhibits a monoclinic crystal structure.
In geothite oxygen is linked to the hydroxyl ions in hexagonal layer like arrangement. This source of hydrogen is humidity/moisture. Thus, geothite will be present more in climates that are more cooler and humid. In contrast, hematite will be more prevalent in dry and warm climatic conditions.

After studying this Module 8, answer the following questions in this Journal: Briefly explain why water is such an important agent in chemical weathering. How do soils that form in humid regions differ from soils that form in semi-arid regions in the environments in which they form and in their basic characteristics? Explain why and give two examples of how climate is more effective in determining soil type than is parent rock type. How does gravity affect a slope? What...
