Rocks Chapter 2
6th grade Advance Science - Rocks Part 2
Question | Answer |
---|---|
The process by which dissolved minerals crystallize and glue particles of sediment together into one mass. | Cementation |
The process by which sediments are pressed together under their own weight. | Compaction |
The process in which sediment is laid down in new locations. | Deposition |
Igneous rock that forms when magma hardens beneath Earth's surface. (granite-continental crust) | Intrusive Igneous Rocks |
Sedimentary rock that forms when minerals crystallize from a solution. (limestone) | Chemical Rock |
Sedimentary rock that forms when rock fragments are squeezed together under high pressure. (conglomerate) | Clastic Rock |
The process by which water, ice, wind, or gravity moves weathered rock or soil. | Erosion |
Igneous rock that forms from lava on Earth's surface. (basalt-oceanic crust) | Extrusive Igneous Rocks |
When the grains of a metamorphic rock are arranged in parallel layers or bands. (gneiss) | Foliated |
This type of rock forms from cooling magma or lava. | Igneous Rocks |
This type of rock forms when an existing rock is changed into a new rock by intense heat and pressure. | Metamorphic Rocks |
When the grains of metamorphic rocks are arranged randomly. (quartzite) | Nonfoliated |
Sedimentary rock that forms from remains of organisms deposited in thick layers. (coal) | Organic Rock |
A series of processes on the surface and inside the Earth that slowly changes rocks from one kind to another. | Rock Cycle |
Small, solid pieces of material that come from rocks or organisms; earth materials deposited by erosion. | Sediment |
This type of rock forms when particles or sediments from other rocks or remains of plants are animals are layered, pressed, and cemented together. | Sedimentary Rock |
The process that breaks down rock (mountains) on Earth's surface. It breaks down the rock into small particles called sediments. | Weathering |
