Weathering
The breaking down of rock into smaller pieces
What is weathering
The process of carrying rock, soil and sediment from one location to another
What is erosion
Wears earth surface down
What is destructive process
(blank) builds earth's surface up
What is constructive process
A desert sand dune is formed by this process.
What is deposition
Weathering can be caused by what four forces
What is ice, wind, gravity and water
Four ways that sediment, rock or soil can be moved
What is gravity, water,wind, and glaciers
One type of destructive process is...
What is a volcano, earthquake, landslide
What landforms could form as a result of volcanic eruptions?
What are mountains or islands
a flat piece of land made up of sediment deposited by a river near its mouth
What is a delta
Mechanical Weathering is...
What is breaking up rock (remember the sand and pebbles)
Ocean waves can cause erosion by...
what is washing away sand deposits
Strong (blank) can destroy buildings, bridges and roads by cracks in the ground
What are earthquakes
the dropping of material by water, wind or gravity
What is deposition?
Shells along the beach are deposited this way
What is ocean waves
Where ice forces rock apart over a period of time (chemical, physical, or mechanical)
What is physical weathering
The force that pulls pieces of rock downhill
What is gravity
(Blank) can cause destruction by killing trees, animals and plants with lava
What is a volcano
(Blank) can build mountains by rocks being pushed up along faults
What are earthquakes
a hill of sand deposited by wind
What is a sand dune
(Blanks) roots can cause weathering by pushing rock apart
What are plants
(Blank) would not happen without gravity
What is erosion
Both volcanoes and earthquakes are destructive, but they can also be....
What is constructive
Mountains can be formed by (blank) hardening after a volcano eruption
What is lava
a huge sheet of ice that moves slowly over land
What is a glacier
