15 Questions
How are igneous rocks formed?
Through the crystallization of molten magma or lava
What can metamorphic rocks be transformed into?
Igneous rocks
How can sedimentary rocks be transformed into magma?
By the weight of the rock itself
How do chemical sedimentary rocks form?
By precipitation of ions from a solution
Where are stalactites, a type of chemical sedimentary structure, usually found?
In caves
What can happen to igneous rocks through subduction and uplifting processes?
They can crystallize out into a new igneous rock
What is the process that involves the infiltration of chemical sediments to act as glue?
Cementation
Which type of sedimentary rock contains pieces and particles from what was once living matter?
Bioclastic rocks
What is the first step in the formation of sedimentary rock?
Weathering
What is the main difference between contact metamorphism and regional metamorphism?
Contact metamorphism occurs next to igneous intrusions, while regional metamorphism occurs over larger areas due to tectonic plate pressures.
What happens to crystal grains during metamorphic rock formation?
Some crystals recrystallize into larger crystals, and some crystallize into new types of minerals under different temperatures.
What is the defining characteristic of foliated metamorphic rocks?
They exhibit visible layers due to the alignment of crystals, sediments, and minerals.
How can a metamorphic rock become an igneous rock?
By melting into magma and then crystallizing as an igneous rock.
What geological process can lead to extreme accumulations of sediments and subsequent metamorphism?
Tectonic plate movements
What is the result when igneous rocks are weathered and eroded by rain?
They transform into sedimentary rocks
Learn about the formation of chemical sedimentary rocks through the precipitation of ions from water solutions. Understand how these rocks are created and their significance as a source of fuel.
