Answer:
Protozoology should be the answer.
In short, it was caused by 3,000 consecutive strong earthquakes. and caused by the freezing of lava causing glass particles.
Red clouds were seen at the volcano. The eruption was the result of intense seismic activity and a high rate of characterization in the weeks prior to the eruption. coupled with magma, which fuels the volcano
The second eruption occurred beneath the ice of a glacier. The cold water caused by the melting of the ice quickly cooled the lava and shattered the frozen lava into glass. This produces tiny glass particles which are carried in the ash spout. which that event As a result, airlines that leave Europe and enter Europe have to shut down for several days. coupled with the size of the eruption This is estimated to be 10-20 times the size of the eruption at Fimverduhaus. This resulted in a high-level atmospheric high-level of glass-contaminated ash plumes. which is dangerous for aircraft
Answer:
chemical change.
Explanation:
There are two types of changes in matter: physical change and chemical change.
physical change- it is a change in matter that alters only its physical properties or its physical appearance. This type of change is reversible. For example- freezing of water, the water turns into solid ice and it can be reversed by melting the ice.
chemical change- it is a change in matter that alter its chemical and thus its physical properties. Most chemical changes are irreversible. for example- burning of paper, results in black soot and ashes- Thus changing both physical and chemical properties.
The scientists rely on the following cues to hypothesise and test for the presence of life on various extraterrestrial bodies:
1. Presence of water
2. Presence of hydrocarbons
3. Presence of carbon
4. Presence of salt pans
The presence of hydrocarbons may indicate that there's anaerobic life thriving beneath the surface of the meteorite. The presence of traces of carbon may indicate that there was life once thriving on its surface ( which however is not possible in case of a meteorite because of its size). The absence of any of the above listed items will indicate that the surface of the meteorite is devoid of any life.
Correct answer: False
A primary source provide the first hand proof and the original information of the event, object, person or work.
Example: Research data, e.g. public opinion polls, speech
Secondary source is that source of information that is not performed or collected by the individual but it is taken from old information. It is updated by someone who is not participation in the event or the research.
Example: Library, ebook, reviews.
