Weathering / Erosion
the set of physical and chemical processes that break rock into smaller pieces
what is weathering?
The number representing all of the agents of erosion
what is four?
The name of the primary feature of sedimentary rocks involving horizontal layering
what is bedding?
the best-known feature of sedimentary rocks
what is fossils?
the most common sedimentary rock
what is clastic sedimentary rocks?
the small pieces of rock that are moved and deposited by wind, water, gravity, and glaciers
what is sediments?
the removal and transport of sediment
what is erosion?
the names for the two types of bedding found in sedimentary rocks
what is graded bedding and cross-bedding?
the preserved remains, impressions, or any other evidence of once-living organisms
what are fossils?
the increase in this causes rock layers to change into metamorphic rocks
what is temperature and pressure?
this forms when sediments become glued together
what is sedimentary rocks?
the name of the area describing where erosion takes place in the baseball example
what is the infield?
the result of sediment being moved into small ridges by wind or wave action
what is ripple marks?
the two things that fossils can prove about organisms
what is what organisms lived and how they have changed over time?
the two types of textural groups for metamorphic rocks:
what is foliated and non-foliated?
the process that involves minerals in rock dissolving or becoming chemically changed
what is chemical weathering?
the process of transported sediments being deposited on the ground or in a body of water
what is deposition?
the name for the layers that form after sediments are deposited across a horizontal surface
the rock where fossils are typically found
the textural group that has rocks with blocky crystal shapes
what is non-foliated ?
the process that involves rock fragments breaking off solid rock along fracture lines
what is physical weathering?
the two areas where sediments are usually deposited
valleys and ocean basins
the two ways that cause bedding to occur
what is water or wind?
the main requirement for organisms to become fossils
what is fossil remains must be buried and undisturbed?
the percentage of open spaces between grains in a rock
what is porosity?
