Types of Rocks
Metamorphic Rocks form as a result of
Heat and Pressure
Fossils are only found in
sedimentary rocks
Sedimentary rocks that have ripple marks suggest that the rocks formed
along a beach or stream bed
A metamorphic rock can be classified according to its
texture and compostion
What is erosion?
sediments and minerals are removed from a area
Rock that forms beneath the Earth's surface when magma hardens
Intrusive Igneous Rock
Limestone is an example of what kind of rock
biochemical sedimentary rock
Most metamorphic processes take place
below earth's surface
What is a solid mass of minerals that occurs naturally
Rock
What is deposition?
When sediments are deposited in a different place
Give me an example of extrusive igneous rock
Rhyolite
Describe Breccia
a clastic sedimentary rock with angular particels
What is a rock-forming process that occurs when hot magma forces its way into rock called?
Contact metamorphism
Igneous Rock that contains mostly proxyene and olivine has what kind of composition?
Ultramafic
what is weathering?
the process of wearing or being worn by long exposure to the atmosphere
When Lava cools so quickly that ions do not have time to arrange themselves into crystals, igneous rocks will form this type of texture
glassy texture
A conglomerate is a rock that forms as a result of
compaction and cementation
What agent of metamorphism can cause the overall composition of the rock to change?
Hydro thermal solutions
Granite is what kind of igneous rocks
intrusive
What is Compaction?
The process when sediments are pressed together under their own weight
Name the 3 types of rocks
Igneous, Sedimentary, Metamorphic
Igneous Rock that contains 25 percent dark silicate minerals. What type of composition does this rock have?
Andesitic
Foliated metamorphic rock forms when crystals
combine and form visible bands
Large-scale folding of rock during the process of mountain building is characteristic of a
Regional
Give me the correct order of how sedimentary rocks form
