Delimiter between question and answer:

Tips:

  • No column headers.
  • Each line maps to a question.
  • If the delimiter is used in a question, the question should be surrounded by double quotes: "My, question","My, answer"
  • The first answer in the multiple choice question must be the correct answer.

Why are sedimentary rocks important to scientists?
 
They record Earth’s surface history
 
They show magma movement
 
They form only deep underground
What would happen if compaction did not occur?
 
Sediments would remain loose
 
Rock would melt
 
Fossils would burn
Which condition is needed for cementation to occur?
 
Presence of mineral-rich water
 
High temperature magma
 
Strong sunlight
Why are older sediment layers usually found at the bottom?
 
They were deposited first
 
They are heavier
 
They formed by heat
What is the main source of sediments?
 
Pre-existing rocks
 
Earth’s core
 
The Sun
Which factor does NOT affect sedimentary rock formation?
 
Magnetic force
 
Water movement
 
Gravity
What happens to pore spaces during compaction?
 
They become smaller
 
They increase in size
 
They fill with air only
Why do sedimentary rocks often contain fossils in good condition?
 
They form slowly at low temperatures
 
They form quickly from lava
 
They cool rapidly
Which sedimentary rock forms from compacted clay?
 
Shale
 
Granite
 
Basalt
How does water help cementation?
 
It carries dissolved minerals
 
It increases temperature
 
It breaks minerals apart
Lithification includes which two processes?
 
Compaction and cementation
 
Weathering and erosion
 
Melting and cooling
Why are fossils rarely found in igneous rocks?
 
Heat destroys remains
 
No layers form
 
Pressure is too low
What evidence shows a rock formed from sediments?
 
Visible layers and grains
 
Interlocking crystals
 
Glassy texture
How does sediment size affect deposition?
 
Larger sediments settle first
 
Smaller sediments always settle first
 
All sediments settle together
What type of sediment forms conglomerate rock?
 
Large rounded pebbles
 
Fine volcanic ash
 
Melted magma
Which environment is MOST suitable for thick sedimentary rock layers?
 
River deltas and seabeds
 
Volcanic vents
 
Mountain cores
Why does cementation usually occur after compaction?
 
Water carries minerals into spaces between sediments
 
Pressure melts sediments
 
Heat fuses sediments
Which mineral commonly causes cementation?
 
Calcite or silica
 
Plastic or rubber
 
Iron metal
What increases the rate of compaction?
 
More layers piling on top
 
Less pressure
 
Lower temperature
Why do sediments form layers?
 
Different sediments settle at different times
 
All sediments fall at once
 
Layers form only underground
During deposition
 
what happens to sediments?
 
They settle when energy decreases
 
They melt into liquid
 
They turn into crystals
What mainly causes erosion of sediments?
 
Water wind and ice
 
Heat from magma
 
Earth’s core movement
Which process changes solid rock into sediments without moving them?
 
Weathering
 
Erosion
 
Deposition
Which sequence correctly shows how sedimentary rocks are formed?
 
Weathering-erosion-deposition-compaction-cementation
 
Melting-cooling-solidification
 
Heat-pressure-recrystallization
