How long does it take coal and other fossil fuels to form?
Millions of years.
Sedimentary rock is easily identified by its ______________.
Layers
What forces cause the formation of landforms?
wind and water
What is weathering?
Weathering is the breakdown of rock into smaller pieces.
What does the CON in CONserve stand for?
Coal, oil, natural gas. We must CONserve our fossil fuels.
Why are fossil fuels called nonrenewable resources?
Fossil fuels like coal, oil, and natural gas take millions of years to form and, therefore, cannot be replaced or “renewed”.
What step is missing from the formation of sedimentary rocks like sandstone?
Weathering – Erosion – Deposition - _______?____ - Cementation
Compaction
Strong winds are most likely to change the shape of which landform?
While strong winds can weather hard rock over time, SAND DUNES would be most affected by strong winds.
Ms. Haley moved from Chattanooga which is a valley. What does this tell you about Chattanooga?
Chattanooga is a low area of land between two mountains/higher areas of land.
(A valley is a low area of land between two higher areas of land.)
Landslides can cause rocks to move to a new locations.
Where do fossil fuels originate?
Sedimentary rock is formed by the layering of sediments. What causes these sediments to form layers?
Sediment gets eroded by wind and water. It DEPOSITS in layers in new locations.
How do deltas form?
Over time, more and more sediments build up and cause the river to form a new branch.
What is likely to cause the formation of a valley?
A glacier sliding down and eroding the side of a mountain.

How is this landform created?
Caves are formed when water flows underground and carries away the minerals and sediment.
How is the fossil fuel oil formed?

Which layer is the oldest layer? How do you know?
A is the oldest layer because it is at the bottom. Over time, other layers have been deposited on top.
Canyons, like the Grand Canyon, are primarily formed by what?
Moving water.
How can ice weather a rock?
Water fills cracks in the rocks. When it freezes it forces the cracks wider. Over time, this thawing and freezing causes the rocks to break into smaller pieces.
A waterfall has been dropping onto the land for a long period of time. After millions of years, this waterfall has formed what landform?
A canyon.
Describe the process that forms the fossil fuel coal.
Peat moss in a swamp gets buried by sediment. Water is squeezed out by the pressure of the above layers and the peat decays. More layers means more and more heat. Heat and pressure turn the organic matter into coal.
What is something that both sedimentary rock and fossil fuels have in common?
Coastal areas often experience radical changes in their coastline. What mostly causes these changes?
Erosion of the coastline is caused by moving water from waves and storms.
How might a weathered mountain appear different from an unweathered mountain?
The weathered mountain would appear rounder and smoother in shape.
Why do we use fossil fuels?
They are relatively inexpensive (cheap) to produce, and they can be found within Earth's lithosphere.
