| 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 |
