Afossilized tree killed by a volcano was studied. it had 6.25% of the amount of carbon-14 found in a sample of the same sized tree that is alive today. when did the volcanic eruption take place

There are a lot different kinds of volcanic activity and eruptions: phreatic eruptions, explosive eruption of high-silica lava, effusive eruption of low-silica lava, pyroclastic flows, lahars (debris flow) and carbon dioxide emission.

It concentrate of different volcanic gases can vary consider from one volcano to the next. Water vapor is typically the most abundant volcanic gas, followed by carbon dioxide and sulfur dioxide. Other main volcanic gases include hydrogen chloride, hydrogen sulfide, and hydrogen fluoride. A huge number of minor and trace gases are also found in volcanic emissions, for example, carbon monoxide, halocarbons, organic compounds, and volatile metal chlorides hydrogen.

a

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.
