stalacite
A deposit of sediment that hangs from the roof of a cave
chemical weathering
What process is the cause of groundwater erosion?
rills
tiny grooves in the soil
moving water
What is the major agent of erosion on Earth's surface?
stalagmite
slow dripping that forms a cone shape
stream
water that is continually flowing down a slope
karst topography
a type of landscape in rainy regions
alluvial fans, deltas, and soil on flood plains
What are the three features that result from deposition along a river?
flood plain, meanders, oxbow lake, valleys, waterfalls
What are five features that erosion forms along a river?
runoff
water that moves Earth's surface
oxbow lake
a river that has been cut off from a meander
carbonic acids break down limestone, limestone changes chemically and is carried away in a solution of water, this process gradually hollows out pockets in the rock, then over time the process develops holes underground, called caves.
How do groundwater erosion and deposirion produce a limestone cave?
alluvial fan
a wide, sloping deposit of sediment formed where a stream leaves a mountain range
meander
a curve in a stream
