is any body of water that flows down a slope in to a channel
area of land on either side of the stream that is underwater when its flooded
twists and turns in a stream channel
meanders that get cut off from the stream channel
fan-shaped deposit of sediment at the base of a mountain
area of land formed by the buildup of sediment at the end of a river
smaller river that flows in to a larger one
outside of meander
inside of meander
steep valley, no meanders
floodplain, some meanders
many meanders and oxbows
Processes by which rock, sand, and soil are broken down and carried away
Process in which sediment is laid down in new locations.
wearing down of rock surfaces by other rock or by sand particles
removal of fine sediment by wind
mounds of wind-deposited sand
millions of tons of fine grained sediment blown far distances and deposited
the general term for all of the materials carried and deposited by a glacier
a glacier that forms in the mountains
A thick sheet of ice covering a mass of land all year round; found ONLY in Greenland and Antarctica!
the slow downhill movement of weathered rock material
the rapid mass movement of rock down a steep slope or cliff
the sudden movement of rock and soil down a slope
the flow of a mass of mud or rock and soil mixed with a large amount of water
5 events that trigger mass movement
heavy rain; deforestation; construction on an unstable slope; earthquakes; volcanic eruptions
occurs in hilly areas; where a single unit of material falls down after a heavy rain
underwater or exposed ridge of sand, gravel, or shell material
created by longshore current over long periods of time; a long ridge of sand or narrow island that lies parallel to the shore
a water current that travels near and parallel to the shoreline
A depression created at Earth's surface when an underground cave collapses.
large boulder left behind by glacial deposition
formed about 7000 years ago from a huge continental ice sheet gouging out the land
formed from strong winds and loose sand
good fertile land for crops
Three things that affect a river's speed.
gradient, load, discharge
5 things that can trigger mass movement
volcanic eruptions, earthquakes, construction on unstable slope, deforestation, heavy rainfall
forms when groundwater levels lower and the roof of the cave collapses
Large areas of slow moving ice, form when more snow falls than melts each year.
