Question | Answer |
Igneous rocks that cool quickly on Earth's surface are ? | extrusive |
The processes involved in the rock cycle include all of the following EXCEPT . | a) condensation |
A is a sedimentary rock made of clasts of minerals of rock fragments. | clasts rocks |
Sedimentary rocks form because of all of the following except ? | b) crystals solidifying from magma |
A is a broken piece of fragment of rock | clasts |
the rock cycle indicates that each type of rock can ? | all of the above |
sediments in sedimentary rocks are often ? | a) held together with natural cements |
which statements is correct regarding metamorphic rock formation? | d) the deeper into Earth's crust, the higher the pressure |
molten rock below the Earth's surface | magma |
molten rock that has erupted onto Earth's surface | lava |
are known as primary rocks | igneous rocks |
when volcanic material erupts, cools, and crystalizes on Earth's surface | extrusive |
when magma cools under ground rocks are formed | intrusive |
are formed when sediments are deposited | sedimentary rocks |
breaking up of rocks into smaller pieces | weathering |
movement or transportation of pieces of rocks | erosion |
compression rocks together | compaction |
dissolved minerals crystalize and cement rocks together | cemitation |
broken pieced or fragments are called | clasts |
kilobars= | kb |
any process that affects the structure of composition of a rock in a solid state as a result of changes in temperature, pressure, or the addition of chemical fluids | metamorphism |
rock that changes during metamorphism | parent rock |
magma comes in contact with existing rock, its thermal energy and gases interact with the surrounding rock | contact metamorphism |
formation of metamorphic rock bodies that are 100's of square kilometers in size | regional metamorphism |
have mineral grains with a random, interlocking texture/no obvious alignment of the mineral crystals | non-foliated |
contain parallel layers of flat and long gated minerals | foliated |
the series of processes that change one type of rock into another type of rock | rock cycle |
a structurally high area in the crust, produced by movements that raise the rocks, as in a broad dome or arch | uplift |
someone who studies rocks | geologist |
slow cooling form crystals | large |
fast cooling form crystals | small |
