| In the rock cycle, sedimentary rocks change to sediments by. | Weathering & erosion. |
| Igneous rocks are formed by this molten material deep inside the earth called. | Magma. |
| These distinguish foliated rocks. | Layers. |
| The only condition on Earth which DOESN'T cause metamorphic rocks to form. | Exposure to air. |
| A classification of metamorphic rocks includes whether or not they are ____. | Foliated or nonfoliated. |
| Formed when loose materials become pressed or cemented together OR when materials form from solutions. | Sedimentary rocks. |
| The only change which metamorphic rocks CAN'T undergo. | Melting. |
| Three examples of fine-grained, extrusive rock. | Gabbro, basalt and pumice. |
| Basaltic igneous rocks include. | Gebbro, basalt and scoria. |
| A frothy, extrusive, felsic, igneous rock that may float on water is | pumice |
| The crystals that form in slowly cooled magma produce what size minerals? | large |
| The crystals that form in quickly cooled magma produce what size minerals? | small |
| Why does magma from deep inside Earth come to the surface? | it is less dense |
| The presence of many metamorphic rocks in Virginia is an indication that the area has been subjected to what | intense heat and pressure |
| Because granite cools below the surface of Earth, it is considered what kind of rock? (three words) | igneous intrusive rock |
| Rock with flattened crystals,colored, parallel layers, and bent from being under pressure are classified as which of the three kinds of rock? | metamorphic |
| Which type of rocks have fossils? | sedimentary |
| Why do metamorphic rocks not have fossils? | pressure would destroy the fossil |
| Why do igneous rocks not have fossils? | The heat would destroy the fossils |
| What processes produce heat and pressure? | rifting and subduction |
| What process makes the sediment from which sedimentary rocks are formed? | erosion |
| What are the processes called that makes sedimentary rock? | sedimentation, cementation and compaction |
| What metamorphic rock is formed because of mountain building processes | gneiss |
| Marble rarely has fossils, because it is what type of rock? | metamorphic |
| One rock forms from another after undergoing metamorphic processes. What is the original rock called? | parent rock |
| Limestone makes ____________ when it undergoes pressure and heat. | Marble |
| What is a rock called that has rounded gravel-sized particles? | conglomerate |
| What is a mixture of minerals, mineraloids, glass or organic matter | rock |
