What is the meaning and definition of a TEM?

 

Transmission electron microscopy (TEM, also sometimes conventional transmission electron microscopy or CTEM) is a microscopy technique in which a beam of electrons is transmitted through a specimen to form an image. The specimen is most often an ultrathin section less than 100nm thick or a suspension on a grid. An image is formed from the interaction of the electrons with the sample as the beam is transmitted through the specimen. The image is then magnified and focused onto an imaging device, such as a fluorescent screen, a layer of photographic film, or a sensor such as a charge-coupled device.

Which Of The Following Is A Sign That A Volcano May Erupt ?, A.Earthquakes, B. Landslides , C.Emission Of Gases And Steam, D. Growth Of Plants And Ani

Which of the following is a sign that a volcano may erupt ? A.Earthquakes B. Landslides C.Emission of gases and steam D. Growth of plants and animals near the volcano   The answer to your question is both A. earthquakes and C. emission of gases and steam. An active volcano is continually piling up pressure inside of it which causes the eruption. It can cause small tremors or earthquakes near the volcano because of the pressure inside the volcano. Emissions of gases and steam on the other hand denotes that the volcano has a built up pressure below it, and therefore can erupt once it needs to release the pressure. These signs are not always taken seriously by volcanologists since they normally happen near an active volcano. However, they issue warnings and cautions, set up hazard areas, and continually monitor the volcano to prevent casualties should the eruption be near. The thing about this is that it is not 100% accurate, volcanologists can only do so much to pr...
