What are two examples of sedimentary rocks?
Limestone or Sandstone are two examples of sedimentary rocks. Two examples of sedimentary rocks are slate (fine silt) and chalk (shell remains of sea creatures).
Does dark colored rock with low silica content describe granite?
Granite is a silicate because it contains 70-77% silica (SiO2). Granite is a rock, and silica is mineral containing the chemical elements silicon (Si) and oxygen (O). Si and O chemically combine to form SiO2. Rocks are made up of minerals, which are made up of chemical elements. Because silicon and oxygen are the two most common chemical elements in the Earth's crust, silicate rocks are very common.
What are the two factors the control whether a volcano eruption will be explosive or quiet?
water vapor and high in silica
What are some examples of felsic and mafic rocks?
Granite and grandiorite are two felsic rocks but I'm seeing that some people cosider granite mafic.
How can a basalt flow cause opal to form?
If the basalt flow contains air bubbles and pockets and there is a spring that contains silica then the silica can deposit into the air bubbles (the air bubbles are known as Amygdaloidal basalt or vesicles) If the silica deposits slowly and the conditions are correct then precious opal can form. Two examples of this would be in California at the Nowak and the Barnett mines.

What does magma with high silica content form?
When it cools and crystallizes into rock, the rock will be described as felsic igneous rock. Examples of felsic igneous rocks are granite, rhyolite, and pumice.
What are two examples of fine-grained igneous rocks?
Basalt and rhyolite are examples of fine-grained igneous rocks.
What are two examples of fined grained igneous rocks?
Basalt and rhyolite are examples of fine-grained igneous rocks.
What are examples of two intrusive rocks?
Basalt and sandstone.
What are two examples of Metomorphic rocks?
Slate and marble are examples of metamorphic rocks. Other metamorphic rocks include gneiss, schist, and quartzite. All metamorphic rocks are formed from other rock types.
What are two examples of rocks?
sedimentary rock and igenous rock.
Two examples of removing rocks from the ground?
chipping and digging
What are two examples of non intrusive rocks?
Basalt and sandstone.
What are some examples of chemical sedimentary rock?
Gypsum and Rock Salt are two examples of chemical rocks (sedimentary rocks).
Give two examples of organically formed rocks?
Coal and amber.
