SEM and TEM are electron microscopes whereas the SEM uses reflected electrons and TEM uses transmitted electrons to form an image

Explanation:

  • SEM is the scanning electron microscopes and TEM is the Transmission electron microscope
  • SEM works by detecting the scattered electrons to create an image of the sample whereas the TEM detects the transmitted electrons to create the image of the sample
  • SEM will only be analysing the surface of the sample whereas TEM collects data vertically also
  • TEM sample needs to cut thinner than SEM and TEM will give high-resolution images than SEM

How can a rise in temperature cause a change in a polar ecosystem
Dvinal [7]

Sea levels would rise.

Increase in temperature (for example due to global warming) increases the rate of melting of polar ice.

Consequently, the sea levels of the polar ecosystem would increase.

In addition, the melting of the ice caps also increases the temperature of the water in the oceans. As a result, the water expands which also increases the sea levels.
