| Question | Answer |
|---|---|
| To describe a rock’s __________________, geologists determine the size, shape, and pattern of the rock’s grain | texture |
| In __________________ ________________rocks, the grains are large and easy to see. | coarse-grained |
| __________________ rock forms from the cooling of molten rock, either magma below the surface or lava above the surface. | Igneous |
| Most metamorphic rock forms ________________ ____________________. | deep underground |
| __________________ igneous rock forms from lava that has erupted onto Earth’s surface. | extrusive |
| The texture of an igneous rock that has large crystals scattered on a background of much smaller crystals is __________________. | porphyritic |
| Chalk formed from sediments made of skeletons of microscopic living things in the ocean must be __________________ rock. | organic |
| __________________ is the process by which sediment settles out of water or wind. | Deposition |
| __________________ is the process in which dissolved minerals crystallize and glue particles of sediment together. | Cementation |
| As layer upon layer of sediments are deposited, the process of __________________ presses them together. | compaction |
| A __________________ rock is a sedimentary rock formed when rock fragments are squeezed together. | clastic |
| The skeletons of tiny ocean animals grow together to form __________________ ___________________. | coral reefs |
| An __________________is a ring-shaped coral island found far from land. | atoll |
| Heat and pressure deep beneath Earth's surface can change any rock into __________________ rock. | metamorphic |
| The heat that changes a rock into metamorphic rock comes from pockets of rising __________________ | magma |
| __________________ metamorphic rock has grains arranged in parallel layers. | Foliated |
| __________________metamorphic rocks have mineral grains arranged randomly. | Nonfoliated |
| A series of processes on Earth's surface and within its interior that slowly changes rocks from one kind to another is the __________________ | rock cycle |
| For igneous rock to form in the rock cycle, rock must be __________________ and __________________. | melted and cooled |
| __________________ occurs when subducting plates push rocks back into the mantle. | Melting |
| In the rock cycle, some rock melts and forms magma in the layer of Earth known as the __________________ | mantle |
| __________________ rock will most likely form if two colliding continental plates squeeze sedimentary rock. | Metamorphic |
| __________________ movements drive the rock cycle by pushing rocks back into the mantle. | Plate |
