Ch. 4 Study Guide Answers Matching E. rock that cools below the Earths surfaceMatching B. metamorphic rock in which mineral grains are NOT arranged in bands
Matching C. rock that cools at the Earths surface
Matching A. process in which layers in sedimentary rock are formed
Matching D. layers found in sedimentary rocks
Sedimentary rock is formed through the process of __cementation_____.
How did humans use rocks in the past? To make tools
What are the main categories of sedimentary rock? Clastic, chemical, organic
What has to increase for metamorphism to occur? Temperature and pressure What kind of metamorphic rock has its mineral grains arranged in planes or bands? Foliated When magma cools quickly, what kind of texture does rock have? Fine-grained
When temperature and pressure change, what can happen to the minerals in rocks? They change into minerals that are more stable.
During the rock cycle, what forms when magma cools? Igneous rock
What is the process in which water, wind, and heat break down rock?Weathering
Besides clastic and chemical, what is the other kind of sedimentary rock?Organic
Besides texture, how else are rocks classified? By their composition What do scientists call the rock that is formed when magma cools below the Earths surface?Intrusive igneous rock
The process in which rocks change shape is called ____deformation _________. Matching D. the quality of a rock based on size and shape of the mineral grainsMatching A. process in which sediment is dropped and comes to rest
Matching E. process by which new rock is made from old rockMatching F. the chemical makeup of a rock
Matching B. process by which sediment is removed from its source
Matching C. naturally occurring solid mixture of one or more minerals and organic matter
Constructed ResponseExplain how minerals contribute to rock composition.
A mineral is solid, nonliving, crystal-shaped, and formed in nature, and a rock is made up of 1 or more minerals. Rock is formed from 1 or more minerals and can become a sedimentary rock (weathering and erosion), igneous rock (magma), or metamorphic rock (heat and pressure).
