TermDefinition
weathering the process by which rocks are broken down into sediments
erosion the process by which natural forces move weathered rock and soil from one place to another.
mechanical weathering example: the cracking of rock caused by the freezing and thawing of water
chemical weathering dissolving, warm and humid
absolute age the number of years since the rock formed
relative age a rocks age compared to the age of the other rocks.
law of superposition determines the relative ages of sedimentary rocks layers.
intrusion inside form when magma hardens below earths surface
extrusion exterior forms when lava flows on earths surface.
fold/fault cut or bend pre-existing rock layers.
fossils the bones of dinosaurs
geological time scale the life forms and geologic events in earths history.
ID, EX causes of erosion gravity: rock slides and landslides and avalanches.RW: most powerful: v-shaped. ice: u-shaped, stations and unsorted. wind: blows away.
ID, EX diff types of mechanical and chemical weathering m: the cracking of rock caused by the freezing and thawing of water. C: dissolving of limestone statue by acid rain, warm and humid.
ID the type of rock that can contain fossils sedimentary
demonstrate an understanding of the law of superposition the oldest layer is at the bottom. each higher layer is younger than the layer.
geological features of gravity mass movements: landslides, rock slides avalanches.
factors that affect rates of weathering surface area,
geological features of running water v-shaped, valleys, meandering rivers, floodplains, waterfalls, and deltas. most powerful agent of erosion
geological features of ice ice: u-shaped and glaciers, striations or deep scratches in rock and unsorted sediments
geological features of wind wind: blows away weathered sediments and sand dunes.
