form of pollution
snowball earth
describes the coldest global climate imaginable
what is weathering vs. erosion
Weathering breaks down rocks, Erosion moves the pieces.
igneous rocks
rocks formed by the cooling of molten rock (either magma or lava)
Typhoon
A tropical cyclone occurring in the western Pacific or Indian oceans
nebula
A large cloud of dust and gas in space
glacial period
a period of ice advance associated with falling temperatures
mechanical weathering vs. chemical weathering
Mechanical weathering- is the breakdown of rock into smaller particles, do not directly affect the rock's chemistry.
Chemical weathering-dissolution, carbonation, oxidation, or hydrolysis of rock and mineral by chemical means only, mostly from reactions with water or the acids contained in rainwater. Other materials are formed in the process.
sedimentary rocks
Rocks formed from the weathering, erosion, deposition, and compaction of other rocks
what is the formation of a hurricane?
when a tropical depression forms and massive amounts of heat and moisture
what are clouds
Collections of particles of water or ice suspended in the air that are visible above the earth's surface
