Lesson Worksheet: Rocks and Minerals Science

In this worksheet, we will practice identifying, naming, and describing igneous, sedimentary, and metamorphic rocks and explaining the formation of each.

Q1:

Which of the following is not a classification of rock?

  • AIgneous
  • BProgressive
  • CMetamorphic
  • DSedimentary

Q2:

Fill in the blanks: Igneous rocks take a time to cool and therefore produce crystals.

  • Aplutonic, shorter, smaller-sized
  • Bvolcanic, longer, larger-sized
  • Cplutonic, longer, smaller-sized
  • Dvolcanic, longer, smaller-sized
  • Eplutonic, longer, larger-sized

Q3:

Which of the following is not a difference between plutonic and volcanic rocks?

  • APlutonic rocks contain large crystals, while volcanic rocks contain small crystals.
  • BPlutonic rocks are igneous rocks, while volcanic rocks are sedimentary rocks.
  • CPlutonic rocks are formed deep underground, while volcanic rocks are formed on the surface.
  • DPlutonic rocks are formed from the slow cooling of magma, while volcanic rocks are formed from the quicker cooling of lava.
  • EVolcanic rocks often contain small holes from the extrusion of gases as they cool, while plutonic rocks do not.

Q4:

Which of the following statements correctly describes the difference between magma and lava?

  • ALava is molten rock underneath Earth’s crust, whereas magma is lava that has extruded to the surface.
  • BMagma is molten rock underneath Earth’s crust, whereas lava is gaseous rock underneath Earth’s crust.
  • CLava is molten rock underneath Earth’s crust, whereas magma is gaseous rock underneath Earth’s crust.
  • DMagma is molten rock underneath Earth’s crust, whereas lava is magma that has extruded to the surface.
  • EMagma is molten rock underneath Earth’s crust, whereas lava is molten soil.

Q5:

What is the correct order for the following statements to explain how sedimentary rocks are formed?

  • AB, F, E, D, A, C
  • BD, F, E, B, A, C
  • CC, D, F, B, E, A
  • DD, B, F, E, A, C
  • EE, C, D, F, A, B

Q6:

On a field trip, a student finds three different rocks. They note the appearance and structure of each rock and record their observations when a small amount of hydrochloric acid is added. Which of the rocks is likely to be a sedimentary rock?

ABC
Smooth texture
White color
Soft
Reacts with HCl, producing an effervescence
Rough texture
White color
Very hard
Reacts with HCl, producing an effervescence
Rough texture
Small holes
Very hard
No reaction with HCl
  • AB
  • BA
  • CC

Q7:

Which of the following correctly identifies the two conditions required to convert igneous or sedimentary rocks to metamorphic rock?

  • AHigh pressure and moisture
  • BLow temperature and low pressure
  • CLow temperature and a metal catalyst
  • DHigh temperature and high pressure
  • EHigh temperature and acidic conditions

Q8:

The image below shows an igneous rock. A student looking at the rock notices it contains a lot of small holes in its structure. Is this igneous rock likely to be plutonic or volcanic?

Pumice stone - igneous rock
  • AVolcanic
  • BPlutonic

Q9:

The image below shows a sample of marble. Which sedimentary rock can be converted to marble?

Mineral marble isolated on white background-edited
  • ASandstone
  • BGranite
  • CSlate
  • DBasalt
  • ELimestone

Q10:

The diagram below shows the various processes that occur under Earth’s crust. Which type of rock is likely to be formed at labels X, Y, and Z?

  • AX: sedimentary, Y: igneous, Z: metamorphic
  • BX: igneous, Y: sedimentary, Z: metamorphic
  • CX: igneous, Y: metamorphic, Z: sedimentary
  • DX: metamorphic, Y: igneous, Z: sedimentary
  • EX: sedimentary, Y: metamorphic, Z: igneous
