Lesson 9 | Igneous Rocks 🌋 - William Pollard | Library

                         🌋    Lesson 9 | Igneous Rocks   🌋 
Objective:  You will investigate the properties by which igneous rocks can be identified.

Rock Sample 1  

1

Using ESRT 6 "Scheme for Igneous Rock Identification" table to complete the data chart and identify rock sample 1.

Rock Sample 2

1

Using ESRT 6 "Scheme for Igneous Rock Identification" table to complete the data chart and identify rock sample 2.

Rock Sample 3

1

Using ESRT 6 "Scheme for Igneous Rock Identification" table to complete the data chart and identify rock sample 3.

Rock Sample 4

1

Using ESRT 6 "Scheme for Igneous Rock Identification" table to complete the data chart and identify rock sample 4.

Rock Sample 5

1

Using ESRT 6 "Scheme for Igneous Rock Identification" table to complete the data chart and identify rock sample 1.

1

Draw a graph the relationship of how the size of the mineral grains is affected by the rate at which molten rock material cools. (be sure to label each axis)

1

How can you determine if an igneous rock has had an intrusive or extrusive origin?

1

What is meant by a vesicular texture and how does it form in igneous rocks?

1

Speculate on the reasons that samples of pumice are able to float in water.

1

Describe the environment of formation for granite and basalt. Compare and contrast the two rock types.

1

Analyze the data in the table above, and explain which rock is most likely granite.

1

Incorporate Use the data for Rock 4 and the fact that it is fine-grained to determine the name of Rock 4.

1

What relationship can be inferred from the graph above?

1

Which is a true statement about granitic magma?

1

Using your answer from questions #24 and #25, Hypothesize what an eruption would be like from a volcano with granitic magma.

1

Use the following terms to create a concept map showing the relationship among position in Earth’s crust and mantle, crystal size, and rock type: fast, slow, slowest, intrusive, extrusive, magma, lava, granite, rhyolite, basalt, gabbro, obsidian, and pumice.
