What is the chant we learned for sedimentary rock formation...with hand motions!!!
Weathering breaks it, erosion takes it, when the motion stops, deposition drops! Millions of years later...compaction happens, and cementation finishes the creation.

What environment is natural gas found in?
Marine/Oceanic

What are the agents of change? With hand motions!!
Wind, Water, Ice

How are u-shaped valleys formed?
Glaciers eroding

What is the scientific vocabulary associated with sedimentary rock formation for "heat and pressure"?
Compaction and Cementation

A. What is the original source of the energy that is stored in fossil fuels?
B. What is the 'special ingredient' that makes fossil fuels and not just sedimentary rock that has the 'A's energy stored in it?
A. The sun! B. Decayed organic matter

Of the 4 main landforms we've discussed, which ones are formed by deposition?
Sand Dunes and Deltas
200
How are sand dunes formed?
Wind depositing

Describe the steps of the formation of coal. (Think about Fern Fossil!)
1. An ancient swap plant dies and falls to the bottom of the land.
2. Sediment is deposited on top of it in layers over millions of years.
3. Compaction and cementation form sedimentary rock and a seam of coal is formed within its layers.
300
How do glaciers move?
Veeeerrrrrrrryyyyyy slowlyyyyyyyy!!!
300
How do sand dunes changes over time?
Wind creates a slow change over time as it erodes sand and deposits it in new locations changing the size and shape of sand dunes.
300
How are deltas formed?
Rivers depositing
400
AND how does that contribute to sedimentary rock formation?
Erosion; it takes the weathered sediment to different locations to be deposited into layers over millions of years.
400
How is petroleum formed?
1. An ancient marine microorganism dies and falls to the bottom of the land.
2. Sediment is deposited on top of it in layers over millions of years.
3. Compaction and cementation form sedimentary rock and oil and natural gas are formed within its layers.

Of the 4 main landforms we've discussed, which ones are made by rivers?
Canyons and Deltas
400
Of the 4 main landforms we've discussed, which ones are formed by erosion?
Canyons and U-Shaped Valleys
400
How are canyons formed?
Rivers eroding
500
What are the 4 types of sedimentary rock we represented in our 'sandwich model'?
White bread = sandstone
Icing, chocolate chips, and cereal = conglomerate
Brown bread = shale
Icing and goldfish = limestone
500
What is missing from this diagram in order for oil to form?
Ancient marine microorganisms/decayed organic matter
500
Explain frost wedging.
Frost wedging is a special type of weathering where water freezes in the pores of sedimentary rock and expands breaking apart the rock in the process.
500
How do deltas change over time?
Rivers create a slow change over time as it erodes sediment/silt and deposits more and more at the mouth of the rivers causing the delta to grow in size over time.

What is a v-shaped valley also known as?
A canyon.
