rock cycle - 8th
8th grade rock cycle/weathering/erosion
Question | Answer |
---|---|
process in which materials on or near earth's surface break down or change | weathering |
freeze and thaw cycle; an example of physical weathering | frost wedging |
chemical reaction of oxygen with other substances; an example of chemical weathering | oxidation |
Type of climate associated with most chemical weathering | warm and wet |
Type of climate associated with most physical weathering | cool and dry |
movement of weathered rock particles | erosion |
5 agents of erosion | water, wind, gravity, ice, and living things |
Final stage of the erosional process in which materials are dropped in another location | depostion |
cooling and crystallization of magma creates | Igneous rocks |
Old rocks that undergo intense heat and pressure creates | Metamorphic rocks |
Sediments that are compacted and cemented together creates | Sedimentary rocks |
cooling beneath the surface forming large crystals | intrusive |
cooling above the surface forming small crystals | extrusive |
obsidian, pumice, granite, and basalt are examples of | igneous rocks |
sandstone, limestone, and shale are examples of | sedimentary rocks |
marble, slate, and quartzite are examples of | metamorphic rocks |
continuous changing and remaking of rocks | rock cycle |
pieces of solid material deposited on Earth's surface | sediments |
Naturally occurring, inorganic solid with a specific chemical composition and a definite crystalline structure | mineral |
Mineral group that contains silicon and oxygen | Silicates |
factors that influence weathering | rock type, surface area, topography, and climate |
Coastal erosion creates | Arches and cliffs |
Coastal deposition leads to | dunes, sandbars, barrier islands, and beaches |
