ES Red Mod Ch 3 Test Rock Cycle

Front

What is rhyolite?

Back

Rhyolite is a fine-grained igneous rock that is high in silica content, typically light in color, and often contains quartz and feldspar.

Front

What type of sedimentary rock is formed from salts left behind when a shallow sea evaporates?

Back

Non-clastic sedimentary rock.

Front

What is the texture of breccia?

Back

Breccia has a clastic texture, meaning it is composed of angular fragments.

Front

What does rapid cooling of magma result in?

Back

Rapid cooling of magma results in the formation of fine-grained igneous rocks.

Front

What is mica?

Back

Mica is a group of silicate minerals known for their sheet-like structure and perfect cleavage.

Front

Define clastic sedimentary rock.

Back

Clastic sedimentary rocks are formed from the accumulation and lithification of fragments of pre-existing rocks.

Front

What is the difference between foliated and non-foliated metamorphic rocks?

Back

Foliated metamorphic rocks have a layered or banded appearance due to the alignment of minerals, while non-foliated rocks do not exhibit this layering.

Front

What is the significance of the rate of cooling in igneous rocks?

Back

The rate of cooling affects the crystal size in igneous rocks; slow cooling allows for larger crystals, while rapid cooling results in smaller crystals.

Front

What are the main components of sedimentary rocks?

Back

Sedimentary rocks are primarily composed of minerals, organic matter, and sediments that have been compacted and cemented together.

Front

What is the rock cycle?

Back

The rock cycle is a continuous process that describes the transformation of rocks through various geological processes, including weathering, erosion, sedimentation, and metamorphism.
