Unit 5: Sedimentary Rocks Review

Sedimentary rocks are formed by...

• Rocks or minerals formed by the cooling and solidification of magma
• Rocks or minerals formed by volcanic activity
• Rocks or minerals formed by the deposition and solidification of sediment
• Rocks or minerals formed by the erosion and weathering of sediment

The term sedimentary comes from the word sedimentum which means..

• layering

• stacking

• squishing

• compacting

_______________ is the process of

“squeezing” or compacting

(squishing) sediments

• compression
• consolidation
• cementation

• compaction

_______________ is the process where dissolved

minerals are deposited in

the tiny spaces among

sediments.

• compression
• consolidation
• cementation

• compaction

A clastic sedimentary rock is one that is...

• Made up of

  weathered bits of

  rocks only

• Made up of

  weathered bits of

  minerals only

• Made up of

  weathered bits of

  rocks and minerals

• Made up of

  chemically eroded bits of

  rocks and minerals

_____________________ form when dissolved

substances precipitate,

or separate, from

water solution.

• conglomerate

• coquina

• chemical/biochemical sedimentary rocks

• clastic sedimentary rocks

Why are fossils only found in sedimentary rocks?

• Other rocks get too hot

• Other rocks are not found in the correct location

• Other rocks have too much coloration

• Other rocks do not have the correct chemical compositon
