Igneous Rocks Review

What is the process of formation of igneous rocks?

• Solidification or crystallization of molten magma or lava

• Volcanic eruption and cooling of lava

• Erosion and deposition of sedimentary rocks

• Metamorphism of existing rocks

What are the two main environments of formation of igneous rocks?

• Sedimentary and metamorphic

• Felsic and mafic

• Granite and basalt

• Intrusive and extrusive

Which type of igneous rocks are formed from lava cooling on the Earth's surface?

• extrusive igneous rocks

• metamorphic rocks

• sedimentary rocks

• intrusive igneous rocks

Which type of igneous rocks are formed from magma cooling beneath the Earth's surface?

• Intrusive igneous rocks

• Metamorphic rocks

• Sedimentary rocks

• Extrusive igneous rocks

What are the three main factors that determine the texture of igneous rocks?

• weathering, erosion, and deposition

• pressure, temperature, and age

• density, hardness, and color

• cooling rate, mineral composition, and presence of gases

What are some examples of extrusive igneous rocks?

• Slate, Shale, Schist

• Basalt, Andesite, Rhyolite

• Marble, Limestone, Sandstone

• Granite, Gabbro, Diorite

What are some examples of intrusive igneous rocks?

• granite, diorite, gabbro

• marble, slate, quartzite

• sandstone, limestone, shale

• basalt, andesite, rhyolite

What is the difference between extrusive and intrusive igneous rocks?

• Extrusive igneous rocks are formed from magma that cools quickly on the Earth's surface, while intrusive igneous rocks are formed from lava that cools slowly beneath the Earth's surface.

• Extrusive igneous rocks are formed from magma that cools slowly beneath the Earth's surface, while intrusive igneous rocks are formed from lava that cools quickly on the Earth's surface.

• Extrusive igneous rocks are formed from lava that cools quickly on the Earth's surface, while intrusive igneous rocks are formed from magma that cools slowly beneath the Earth's surface.

• Extrusive igneous rocks are formed from sedimentary rocks, while intrusive igneous rocks are formed from metamorphic rocks.

How are igneous rocks important in the rock cycle?

• Igneous rocks are not important in the rock cycle.

• Igneous rocks are formed from sedimentary rocks.

• Igneous rocks are only found on the surface of the Earth.

• Igneous rocks are important in the rock cycle because they are formed from the cooling and solidification of magma or lava.
