what do we call small particles that could cement together to form a rock
sediments
when heat changes a rock's physical form but doesn't turn all the way to a liquid then it recrystallizes into a new rock this would be an example of
metamorphism
rock that formed inside the Earth’s crust (from
magma)
intrusive plutonic
igneous
when the minerals in the rock are dark in color
mafic
a change in form
metamorphism
What are rocks made up of
minerals
why might you find a metamorphic rock near a magma intrusion
because the heat and pressure of the magma pushing through it would cause the rock that was already there to change.
defined by the grain size and distribution in the rock
texture
igneous when there is a large amount of Fe or Mg in the rock and very little Al
ultramafic
when a small sedimentary particle collects small mineral precipitates and is rolled back and forth by ocean currents creating a small sphere of minerals.
ooids
Name the agents of metamorphism
heat and pressure
inside a mountain we commonly find what type of rock?
metamorphic
when the igneous rock has very fine grains that are difficult to distinguish from one another, forms from very fast cooling extrusively
Aphanitic
rock that forms from sediment deposits that have been compacted and cemented
sedimentary rock
when wind or water carries sediments over a hole, valley or ridge and sediments get deposited at an angle, and over the years the wind patterns shift and begin to deposit sediments in the opposite direction, creating layers that are deposited in opposite directions
Cross-bedding
what is a sedimentary rock with large chunks of other rocks in it
clastic
rock that is older than the rock in which it is encased
inclusion
igneous. when the minerals in the rock are light in color
felsic
rock that is the result of a previously existing rock being exposed to immense heat and/or pressure
metamorphic rock
when rocks are arranged into horizontal layers based on size, happens as a result of massive movement like an earthquake or landslide
grading
are the crystals in a aphanitic texture rock easily visible? yes or no
no
list the steps of a sedimentary rock in order
erosion deposition compacting cementing
igneous
when the minerals in the rock are both light and
dark in color
intermediate
no stipes and no bands on a metamorphic rock
non foliated
when sediments are pushed by water or wind into small ridges and valleys that look like ripples on water and are then cemented in that formation
ripple marks
