  3. Shale

  4. Marble

  5. Granite

Show answer
Correct Option: C
Explanation:

Shale is a sedimentary rock.

Which is TRUE about sedimentary rocks?

  1. limestone is made of nitrate minerals

  2. limestone readily fizzes with acid and limestone is made of carbonate minerals

  3. the red of sandstone is usually due to calcium compounds

Show answer
Correct Option: B
Explanation:

yes, it is true about limestone which is a sedimentary rock.

Which rock description is most likely to be that of the basalt?

  1. usually orange-red, porous, sometimes fossils

  2. larger crystals, many colours, close grained (non-porous), no fossils

  3. dark coloured, close grained, small crystals, no fossils

  4. usually white-grey-yellow, often fossils, porous

  5. usually white,porous,sometimes fossils

Show answer
Correct Option: C
Explanation:

yes,It is basalt,which is a igneous rock.

Which description corresponds to erosion?

  1. wearing away of a rock face

  2. settling out of rock grains or stones

  3. moving rock fragments by water, wind or glacier

  4. breaking down rocks into smaller fragments by someone

  5. breaking up of rocks by wind or rain

Show answer
Correct Option: A
Explanation:

yes,it is related to erosion.

In general, rocks can best be described as a

  1. mixtures of compounds

  2. pure element

  3. pure compound

  4. mixtures of metals

  5. mixture of acids

Show answer
Correct Option: A
Explanation:

Rocks are formed by the deposition of many inorganic minerals. So, it is a mixture of compounds.

What can you say from the experiment? A lump of basalt was weighed before and after dipping into water. The experiment was repeated with a lump of sandstone. The sandstone produced bubbles and gained significant weight. The basalt produced no bubbles and weighed about the same.

  1. the sandstone is more porous than basalt

  2. the basalt is made of large crystals

  3. the basalt is more dense than sandstone

  4. the sandstone removed the dissolved air from the water

  5. basalt has many layers

Show answer
Correct Option: A
Explanation:

Yes, sandstone is more porous than basalt,because it is a sedimentary rock.

Which sequence most closely describes the process of forming sandstone?

  1. burial, pressure, cementation, recrystallisation

  2. burial, melting, cooling

  3. weathering, erosion, transportation, deposition, burial, pressure, cementation

  4. may involve burial first, heat and/or pressure, recrystallisation without melting

  5. transportation, weathering, erosion, deposition, burial, cementation

Show answer
Correct Option: C
Explanation:

yes , it is the right sequence of forming sandstone.

Which statement is TRUE about fossils?

  1. they cannot be used to date rock formations

  2. the deeper a fossil is the more recent it is

  3. fossils are found in igneous rocks

  4. they cannot provide evidence for 'continental drift'

  5. they tell us much about the evolution of animal species

Show answer
Correct Option: E
Explanation:

yes, fossils tell us very much about the animal species.

Which statement is TRUE about weathering due to plant growth?

  1. the water running of the leaves is more acid than rain

  2. root growth in a crack can cause the rock to crack

  3. there will be more weathering due to the plant in winter

  4. it is a chemical form of weathering

  5. plant has no role in weathering

Show answer
Correct Option: B
Explanation:

Yes, the plant root grows into the narrow cracks,as the plant grows, the roots become thicker and break the rocks.

  3. Marble

  4. Granite

  5. Quartz

Show answer
Correct Option: C
Explanation:

Marble is a metamorphic rock which is formed from the action of heat and pressure on limestone.
