Weathering
What is Weathering?
Process that breaks down rock into sediment.
What is the definition of EROSION?
When sediment is moved from one place to another.
What is the definition of DEPOSITION?
When sediment is dropped in a new place.
Are Fossil Fuels Renewable or Non-Renewable?
Non-Renewable. They take millions of years to form.
What are sedimentary rocks?
Rocks made out of different types of sediment.
True or False: Weathering is the only process that is involved in landform formation.
FALSE!!!!!!
Erosion and Deposition also lead to landform formation.
What process happens once erosion has stopped?
Deposition.
What landform is formed by silt deposited from a river to the ocean?
Delta
What is the difference between renewable and non-renewable resources?
Renewable resources can be used multiple times and can be replenished quickly.
Non-Renewable can't be replenished quickly or used multiple times.
Over millions of years heat and ________ create sedimentary rock.
Pressure
What is the definition of sediment?
Broken Down Rock
Sediments are transported at different speeds. Which type of sediment transport is the slowest?
Transport by glaciers.
How are Sand Dunes and Delta's similar?
Both are formed by the the erosion of sediment. Both are formed once the sediment is deposited at a new location.
Name 3 Fossil Fuels
1) Oil/Petroleum/Petro
2) Coal
3) Natural Gas
Both formed by pressure over very long period of time.
What are three agents of change that can cause weathering?
Water, Wind, Ice
True or False: Erosion can occur both quickly and slowly.
TRUE!
When sedimentary rocks are formed what process occurs after the deposition of sediments?
What is coal formed from and where is it formed?
Formed by plants.
Formed in Swamps.
What is Cementation?
The process where the compacted layers harden and turn into rock.
You come across a giant rock that is split in half down the middle. What type of weathering most likely occurred?
Water frozen inside the rock and then thawed, which broke it apart.
How are canyons and mesa's similar
Both are formed by erosion by wind and water.
A fence was built between a sand dune and a road. What was the most likely reason?
To prevent the deposit of sediment all over the road.
What is the material that creates fossil fuels?
Decayed organisms.
Describe the process of compaction.
Pressure from the above layers pack the sediment layers tightly.
