Gly 2010 test 2 (Answered) 100% Correct.
Which of the following features would indicate an igneous rockcooled quickly?
small mineral crystals
What distinguishes a felsic extrusive rock (rhyolite) from a felsic intrusive igneous rock (granite)?
crystal size
Where is the most likely location for molten rock to cool and minerals to form quickly?
at Earth's surface
The presence of large amounts of igneous rocks composed of small mineral crystals is suggestive of
what process occurring in the past?
volcanic eruptions
Weathering that results in the transformation of one mineral into a different kind of mineral is
referred to as _____ weathering.
chemical
Which is an example of chemical weathering?
dissolving limestone by rainwater
Biological sediment includes
shells
Which assemblage of minerals would indicate the lowest weathering intensity?
quartz, feldspar, pyroxene, amphibole
As sediment is weathered and transported:
angular grains become rounded.feldspars are weathered to clay minerals.particle size becomes
smaller due to abrasion.quartz fraction increases as other minerals are winnowed out.
Well-rounded sediment suggests sediment has been____
transported a long distance
well-sorted quartz sand clasts were most likely deposited:
in a beach or dune environment
he occurrence of conglomerate, sandstone, and mudstone with asymmetrical ripples, mudcracks,
and root traces suggest a ____ environment.
river and floodplain
The occurrence of limestone and fossil coral suggest a _____ environment.
reef
Through compaction and cementation, sediment particles:
