Terms
sediments carried from place to place by erosion and put in a new place
deposition
the breaking of larger rocks into smaller rock, called sediment
mechanical/physical weathering
a force that builds up surface features
constructive forces
can cause mechanical weathering
living things
what 2 things create chemical weathering, and changes rocks into other materials
water and weak acids
deposition builds up the land and creates new surface features such as
sand dunes and deltas
mech./physical weathering is done by...
wind, water, ice, and living things
a force that breaks down surface features
destructive processes
plant _____ can grow through cracks and break apart rocks
roots
three types of faults
normal, reverse, strike-slip
an area of new land at the mouth of a river
delta
in colder climates, what plays a major role in weathering
ice
the process by which sediments are moved from one place to another
erosion
_______ ______ push against rocks and allow water to move deeper into rocks and soils
burrowing animals
a normal fault is caused by
tension
when moving water slows down, sediment drops out of the water and gradually build up to form...
new land features such as deltas
as water freezes it _______ and can break the rocks apart
expands
moving water in streams, rivers, and oceans carries __________
sediment
the main factor that causes chemical weathering
water
reverse faults are caused by___
compression
____ ____ can cause mechanical weathering
Living things
moving _____ and _____ cause mech. weathering, like blown sand, or rushing water.
air / water
a stream slowly erodes a river channel.... creating a valley that becomes a _______
canyon
what does chemical weathering form below the surface
caves
strike-slip faults are caused by ______
sheer stress
