five characteristics of a mineral

Classify minerals according to the two major compositional groups

Classify minerals using common mineral identification techniques

Explain special properties of minerals

Describe what makes a mineral crystal a gem

Describe the environments in which minerals are formed

Compare and contrast the different types of mining

metamorphic rock

igneous rock

sedimentary rock

sediment

What can all of the rock types do

What do rocks turn into as a result of weathering and erosion?

List and describe two characteristics of rock that are used to help classify it.

How do the three types of sedimentary rock form?

Describe how the mineral composition of rocks change as they undergo metamorphism

What are the differences between felsic and mafic igneous rocks? Provide examples for each.

What is the difference between how igneous rocks are formed on the surface and how they are formed below the surface?

Describe the 3 different ways that rock can melt and form the magma that later cools to form igneous rock

What are 4 main intrusive igneous rock formations?

Contrast uniformitarianism and catastrophism

Describe how the two theories have contributed to modern-day Earth Science
They still use both methods today

Explain how relative dating is used in geology

Explain the principle of superposition

Demonstrate understanding of geologic column

Identify two events or features that disrupt rock sequences

Explain how radioactive decay relates to radiometric dating

List three types of radiometric dating

Determine the best type of radiometric dating to use to date an object

describe how different types of fossils are formed

List the types of fossils that are not a part of an organism

Demonstrate how fossils can be used to determine changes in environments and in the organisms the fossil came form.
