Rock Test
My test questions over rocks
| Question | Answer |
|---|---|
| Solid mixtures of crystals or one or more minerals | rock |
| Process by which new rock forms form old rock | rock cycle |
| Process by which sediment is removed form its source | erosion |
| Process by which sediment is dropped and comes to rest | deposition |
| The chemical makeup of a rock | composition |
| The size, shape, and position of grains that make up a rock | texture |
| This rock is not normally used as a construction material | halite |
| Scientists classify rocks by what? | composition and texture |
| What kind of texture does igneous rock have when magma cools slowly? | coarse-grained |
| What kind of texture does igneous rock have when magma cools rapidly? | fine-grained |
| What kind of rock is formed when magma intrudes into other rock? | intrusive igneous rock |
| Over time, grains of sand may be compacted and cemented together to form a rock called what? | sandstone |
| dissolved minerals separate from water and Become a natural, what, that binds the sedimentary rock together? | cement |
| Sedimentary rocks form at or near the Earth's what? | surface |
| The most noticeable feature of sedimentary rock is often its layers, or what? | strata |
| Rock or mineral fragments are called what? | clasts |
| Sedimentary rock that forms when rock or Mineral fragments are cemented together is called what kind of sedimentary rock? | clastic |
| Clastic sedimentary rocks can have coarse-, medium-, or fine-grained what? | textures |
| Sedimentary rock that forms when minerals crystallize out of solution, such as sea water, to become rock is called what kind of sedimentary rock? | chemical |
| Sedimentary rock that forms from the remains, or fossils, of plants and animals is called what kind of sedimentary rock | organic |
| Some limestone is made from the skeletons of tiny what that live in the ocean in huge colonies called what? | coral and reefs |
| Limestone made from the calcium carbonate form skeletons and shells of sea creatures is called what kind of limestone | fossiliferous |
| What is the process in which sedimentary rocks are arranged in layers? | stratification |
| What are the markings on sedimentary rocks that record the wave motion of wind and water called? | ripple marks |
| What do we call the structures that form when fine-grained sediments at the bottom of a shallow body of water are exposed to the air and dry out? | mud cracks |
| Which rock's name comes from the Greek words for "changed" and "shape"? | metamorphic |
| What kind of rocks are rocks in which the structure ,texture, or composition have been changed | metamorphic |
| What force or forces can create metamorphic rocks? | heat and pressure |
| A rock in which coarse-grained minerals separate into distinct bands | gneiss |
| A foliated metamorphic rock made from shale | slate |
| A metamorphic rock with mineral grains in planes or bands | foliated |
| a metamorphic rock made from phyllite that has been exposed to heat and pressure | schist |
| a sedimentary rock made of layers of clay | shale |
| a metamorphic rock made from slate that has been subjected to heat and pressure | phyllite |
| What is a change in the shape of a rock caused by a force placed on it called? | deformation |
| Explain the process by which sedimentary rock forms | through cementation and deposition |
| What are the three main categories of sedimentary rock? | organic, chemical, and clastic |
| What do we call metamorphic rocks in which mineral grains are NOT alligned ? | nonfoliated |
| What is the process in which a mineral changes composition during metamorphism called? | recrystallization |
| After quartz limestone has recrystallized, the new rock is called what? | quartzite |
| The heat and pressure at which some metamorphic rocks originally form allow them to sometimes remain what at pressures and temperatures that would melt other rock | solid |
| Pressure caused by large movements within the crust sometimes cause the what in metamorphic rocks to align themselves in parallel bonds | mineral grains |
| During what, is rock heated by nearby magma | contact metamorphism |
| The effect of heat on rock decreases as the rock's what from the magma increases and its what what increases? | distance and temperature |
| When pressure builds up in rock which is located under other rock formations, regional metamorphism occurs | regional metamorphism |
| Regional metamorphism occurs deep in the Earth's what? | crust |
| The minerals that a rock is made of determines the what of that rock | composition |
| what is a naturally occurring solid mixture of crystals of one or more minerals | Rock |
| Sediments are transported or moved from their original source by a process called what | eroision |
| When sedimentary rock is exposed to heat and pressure, what does it change in to? | metamorphic rock |
