Exam 6: Weathering, Soil, and Sedimentary Rocks

Explain why and give two examples of how climate is more effective in determining soil type than is parent rock type.

Graded bedding forms when:

____________________ is an essential component of soil as it provides nutrients to plants and increases the ability of the soil to retain ____________________.

What are the two most common cements in sedimentary rocks?

A vertical sequence of transgressive facies shows an offshore facies superposed on nearshore facies.

Briefly explain how hydrolysis results in the weathering of some minerals.

What are the requirements for a rock body to serve as a reservoir rock for hydrocarbons?

If all of the grains in a sedimentary rock are about the same size,shape,and composition,the rock can be characterized as:

What are some of the characteristics of sedimentary rocks that are used in determining the depositional environment represented by a facies?

How does mechanical weathering differ from chemical weathering?

Is banded iron formation a chemical or detrital sedimentary rock? Explain.

____________________ erosion occurs when water carves small channels into a soil bed.

The properties used to describe detrital sediment are:

What processes lead to soil degradation?

What makes up a chemical sediment?

Detrital sediments and rocks are classified by:

What is an example of an evaporite sedimentary rock?

____________________ form when layers are deposited at an angle to the surface and the layers dip in direction of ____________________.

Briefly explain how dolostone is formed.

The actions of ____________________ and ____________________ are responsible for most soil erosion.
