8th grade rock cycle/weathering/erosion

QuestionAnswer

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

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
