In general, if a body of igneous rock is subjected to partial melting, the magma that is produced is expected to be

more felsic than the source rock.

Though typically nonfoliated, both marble and quartzite can be foliated if

differential stress is applied to the protolith.

How is the half-life of a radioactive parent isotope defined?

the time it takes for half of the parent isotope to decay to a daughter

Volcanoes are able to cool global climate in which of the following ways?

Aerosols and ash reflect sunlight, causing cooling.

How are chalk and chert different?

They have different chemical compositions.
