Sedimentary Rocks & Rock Formation

Sedimentary Rocks are formed in -

• layers

• fragments

• pieces

• lava

Which layer is the oldest layer?

• Top layer

• Bottom layer

• Middle Layer

Sediments get deposited in 

• buckets

• rocks

• layers

What the correct order of Sedimentary Rock Formation?

• Weathering, Erosion, Deposition, Cementation, Compaction

• Weathering, Erosion, Deposition, Compaction, Cementation

• Weathering, Deposition, Erosion, 

  Compaction, Cementation

What percentage of exposed rock found on the Earth's surface are sedimentary?

• 125 %

• 80%

• 25 %

• 75%

the sediments have been cemented, means -

• the sediments have been broken into smaller pieces of rock

• the sediments have been glued together 

• the sediments have been turned into gel.  

On the top layers of a sedimentary rocks we find the  -

• the oldest layers of sediments

• the youngest, newer layers of sediments

• there no sediments found 

How sedimentary rocks are formed from -

• fossil fuels that have been petrified over time

• dead plants and animals that have turned into rocks 

• sediments that have been deposited, compacted and cemented over long periods of time

What is weathering of a rock or the Earth's surface? 

• Weathering is the breaking down of rocks by water, wind and ice, into smaller particles, called sediments. 

• Weathering is the movement of sediments by the weather.

• Weathering is the placement of sediment elsewhere by the atmospheric preassure. 

What is erosion? 

• Erosion is when weathered sediments have become stable and are not moving anymore.

• Erosion is when weathered sediments are moved by water, wind or ice.
