- delta
- sediment deposited where a river flows into an ocean or a lake and builds up a landform
- groundwater
- underground water
- tributary
- a stream or river that flows into a large river
- gully
- a large channel in the soil that carries runoff after a rainstorm
- 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
- flood plain
- flat wide area of land along the river
