weathering
the breaking of rock without changing the rock material
what is physical (mechanical) weathering
the transport or movement of weathered materials
what is erosion?
the drop off or settling of eroded material
what is deposition?
a natural feature of the Earth's surface such as mountains, valleys, rivers
What is a landform?
the outline of a coast
what is a coastline?
The changing of rock material into new material
What is chemical weathering?
wind and water
what are agents of erosion?
place where deposition takes place
what are beaches, floodplains, or river deltas?
what is a delta?
a large cave or chamber in a cave
what is a cavern?
4 examples of physical weathering
What are abrasion, ice wedging, plants, and animals?
wind
what is the primary agent of erosion in the dessert?
describe how sediment is deposited
what is by the transporting medium losing energy, allowing particles to settle?
a pile of windblown sand
what is a sand dune?
type of valley formed by glacier erosion
what are U-shaped vallies?
Examples of chemical weathering
What are oxidation and acid rain?
the main cause of erosion in coastal areas
What are ocan waves?
how does deposition contributes to the formation of landforms over time
What is by laying down sediment over time?
a body of water surrounded by land
what is a lake?
type of valley formed from river erosion
what are V-shaped valleys?
the breaking, scraping, and/or scratching of a rock by moving pieces of sediment (debris)
What is abrasion?
the process that transports sediments down a coastline
what is a longshore current?
explain the role of rivers in deposition
rivers carry sediment and when water slows down, such as a delta, the sediment is deposited
a large mass of ice formed by snow accumulation
what is a glacier?
an area of permeable rock that holds significant amounts of water
what is an aquifer?
