Venn diagrams are used for comparing and contrasting
topics. The overlapping sections show characteristics that
the topics have in common, and the sections that are
unique to each topic show the characteristics that apply to
only that topic. This Venn diagram is comparing longitudinal
waves and transverse waves.
Parallel motion
Particles
only move
a small
amount
Perpendicular
motion
Where is the error in this Venn diagram?
Like moving a
spring up and
down
Particles do
not travel
with the
wave
Like moving a
spring back
and forth
"Parallel" and "Perpendicular" are switched.
The spring descriptions of motion are switched.
Particles travel along the wave in longitudinal waves.
Particles move long distances in transverse waves.

only about ten percent of the energy at one trophic level is passed on to organisms at the next trophic level. the remainder of the energy is used in life processes or lost as heat.

oxygen is the first element in group 16 (via) of the periodic table. the periodic table is a chart that shows how chemical elements are related to each other. the elements in group 16 are said to belong to the chalcogen family. other elements in this group include  sulfur, selenium, tellurium,  and  polonium.  the name chalcogen comes from the greek word  chalkos,  meaning "ore." the first two members of the family, oxygen and sulfur, are found in most ores.

oxygen is by far the most abundant element in the earth's crust. nearly half of all the atoms in the earth are oxygen atoms. oxygen also makes up about one-fifth of the earth's atmosphere. nearly 90 percent of the weight of the oceans is due to oxygen. in addition, oxygen is thought to be the third most abundant element in the universe and in the solar system.
