What are three types of Igneous rocks?
Basalt, Diorite, Rhyolite

What are the 3 major groups of Sedimentary rocks?
The 3 major groups of sedimentary rocks are clastic rocks, organic rocks, and chemical rocks.

After the Metamorphic rock forms does the Rock Cycle keep going?
Yes the Rock Cycle keeps going on and on.
200
What are Igneous rocks classified by?
Igneous rocks are classified by their origin, texture, and mineral composition.
200
What are 3 types of Sedimentary rocks?
3 types of Sedimentary rocks are sandstone, limestone, and shale.
200
What are the 3 most common types of Metamorphic rocks?
The 3 most common Metamorphic rocks are slate, marble, and quartzite.

People through out history have used Igneous rocks for what?
Igneous rocks are used for tools and building materials.

A certain rock contains large, jagged pieces of other rocks, cemented by fine particles. What type of rock is this?
It is breccia a clastic Sedimentary rock.
300
What does Foliated and Non-Foliated mean?
Foliated describes the thin, flat layering found in most Metamorphic rocks. Non-Foliated means the mineral grains in these rocks are arranged randomly.
400
An Igneous rocks color is primarily determined by what?
Igneous rocks color is primarily determined by its silica content.

What is Compaction and Cementation?
Compaction is thick layers of sediment built up gradually over millions of years. The weight of new layers can squeeze older sediments tightly together. Cementation is while compaction is taking place, some minerals in the rock slowly dissolve in the water. Cementation is the process in which dissolved minerals crystalize and glue particles of sediment together.

Why do you think slate might be denser than shale?
Slate is denser than shale because it has layers.

How are Igneous rocks formed?
As these pockets of magma cool slowly underground, the magma becomes Igneous rocks. Igneous rocks are also formed when volcanoes erupt also known as volcanic activity, causing the magma to rise above earths surface. When magma appears above the earth it is called lava. Igneous rocks can be formed in ground also known as intrusive, or underground also known as extrusive.

How are Sedimentary rocks formed?
Sedimentary rocks are formed when small particles of rocks or the remains of animals are pressed and cemented together. They also formed through a process of weathering, erosion, deposition, compaction, and cementation.

How are Metamorphic rocks formed?
Metamorphic rocks are formed By the physical or chemical alteration by heat and pressure of an existing igneous or sedimentary material into a dense form.
