Rocks

Which statement about the rock cycle rock cycle is not true?

• Cementation is a process that leads to sedimentary rocks.

• When heat is applied to a rock and it melts, it may form a metamorphic rock.

• A sedimentary rock in the future may change into another type of sedimentary rock

• Solidification is always needed to form an igneous rock. Solidification is always necessary to form an igneous rock.

Which of the following is a characteristic of igneous rocks?

• Found near volcanic or previously volcanic regions

• Contain skeletons of sea creatures

• Formed in layers

• Subjected to heat and pressure

Rocks that are formed from sediments that have settled at the bottom of a lake, sea or ocean are called:

• Igneous

• Sedimentary

• Metamorphic

• All of the above

Rocks that have been subjected to tremendous heat and/or pressure, causing them to change into another type of rock are called:

• Igneous

• Sedimentary

• Metamorphic

• All of the above

Where extrusive igneous rocks do could be found?

• Near volcanoes

• Deep inside the crust

• On magma hotspot

• Near water bodies

How do you classify metamorphic?

• According to the presence of silica

• According to the place where it formed

• According to its banded appearance

• According to its mineral composition

Which of the following shows the sequence on how an igneous rock could change into metamorphic rock then into magma?

• melting → crystallization → heat and pressure

• melting → heat and pressure → crystallization

• crystallization → melting → heat and pressure

• crystallization → heat and pressure → melting

How does the igneous rock forms?

• By solidification

• By cementation

• By heat and pressure

• By weathering

Which of the following locations describes one example of a place where igneous rocks are forming?

• in a streambed or riverside

• on the surface of the sea floor

• everywhere beneath the earth's surface

• near or below an active volcano

Which of the following best describes a sedimentary rock?

• Can be classified based on the grain size

• Forms where there are bodies of water and usually contains fossils within it

• Undergone with the process of cooling and crystallization

• Can transformed into other rock depending on what process applied to it
