Sand grains are classified as:
immature, young, old, or mature
immature, young, old, or ancient
embryonic, young, old, or mature
immature, middle-aged, old, or mature
Sand from different locations contains different combinations of minerals. The most common mineral found in sand is:
an iron compound
mica
quartz
feldspar
Continental sand is composed mostly of quartz, mica, feldspar, and dark-colored minerals like hornblende or magnetite. If a high percentage of quartz is present, it means the sand is:
very young
from a polar climate
very old
from a temperate climate or high altitude
Volcanic sand is usually dark in color due to the presence of:
green basalt or black olivine
black basalt or green olivine
black basalt or black olivine
green basalt or green olivine
Volcanic sand is very
old and contains little or no feldspar, except for obsidian particles.
old and contains little or no quartz, except for obsidian particles.
young and contains little or no quartz, except for obsidian particles.
young and contains little or no feldspar, except for obsidian particles.
When is the best time of day to sight possible gravesites?
after a fresh rain or snow because the heat of the decaying body causes changes in how the moisture collects on the ground
when the sun is low and shadows are easier to see
after a wind storm because debris tends to collect in the area immediately surrounding the gravesite
all of these
What are the four primary sources of sand?
continental, compressed ash, feldspar, and mica
magnetite, skeletal, precipitate, and granite
continental, volcanic, muddy, and rock
precipitate, skeletal, volcanic, and continental
Oolitic sand can be found in various places including:
near Florida beaches
near Great Salt Lake
near Georgia beaches
near Lake Michigan
Distinct layers of soil are commonly labeled either O, A, E, B, C, or R. A term used to describe this sequence of layers is (a) .
Calcium carbonate will sometimes precipitate out of seawater, forming a coat of hard particles that resemble the layers of an onion. These layers eventually form small, round structures called (a)
(a) is the term used to describe the organic material contained in soil which includes decaying plants and animals
The materials that make up a type of soil determine that soil's (a) properties. An important chemical property of soil is whether it is acidic or alkaline (basic).
In anaerobic environments, the gases cadaverine and putrescine are produced by the decomposition of body proteins. Their stench can attract trained (a) dogs to bodies in shallow graves.
