WEDCC
Weathering
breaks it
What causes the day and night cycle?
Earth's rotation
How are canyons formed?
Weathering and Erosion
(river)
What are Fossil Fuels?
the remains of dead organisms used for fuel
Non-renewable
What is wind energy?
Wind energy is energy gathered from the wind using Wind Turbines.
wind spins turbine, generator stores electricity
Erosion
moves it
What causes Earth's seasons?
Earth's revolution
How are Sand Dunes formed?
Erosion and Deposition
Wind carries sediment and deposits it in a new location forming a hill-like structure.
How is coal formed?
heat and pressure
What is Solar Energy?
Energy from the Sun stored in solar panels.
Deposition
drops it
How long is Earth's revolution?
365 days
What is a Delta?
A triangular shaped (fan-shaped) structure that forms at the mouth of a river because of erosion and deposition of sediments.
How are oil/petroleum formed?
Tiny dead sea organisms that were trapped under sedimentary layers that became sedimentary rock
heat and pressure
Energy from moving water
Water held back and then released through pipes spins a turbine and generates electricity.
Compaction
sediments squeeze into layers
(pressure)
How long does it take for Earth to complete a rotation?
24 hours
What are the slow changes?
WEDCC
How is natural gas formed?
What is Geothermal Energy?
Energy from inside the Earth.
Water is pumped underground, the heat from the Earth turns it into steam, it shoots out and spins a turbine to generate electricity.
Cementation
the sediment layers harden into sedimentary rock
(glues)
The Sun rises in the ________ and sets in the _______.
East
West
What are the fast changes?
volcanic eruption resulting in volcanic islands
earthquake
landslide after heavy rains
What is non-renewable?
CANNOT be made again
What is Biomass/Biofuel?
Energy from living/once living organisms.
Plants and Animals
