The main determining factor in defining boundaries between layers of earth's atmosphere would be temperature changes in these layers. Temperature is one essential property that varies in the atmosphere. Based from this variation, the atmosphere is divided into four major layers and further to three smaller layers - troposphere, tropopause, the stratosphere, stratopause, the mesosphere, mesopause, and the thermosphere.The troposphere is the layer that is nearest to the surface of the Earth. It is the part where humans, plants and animals survive. Also, it is the warmest layer of the atmosphere. And as we go higher the atmosphere, the temperature would drop making it much cooler.
It will be traveling exactly 24 miles per hour <span />
Answer:
both magnesium and strontium have 2 valence electrons
Explanation:
potassium has 8 valence electrons, and nitrogen has 5.
Higher resolution cannot be achieved with a light microscope because wavelength of light is larger that wavelength of electrons.
<h3>What is light microscope?</h3>
Light microscope is defined as the type of microscope that makes use of visible light to magnify objects into images that can be observed.
The wavelength of light is larger than that of the electrons, therefore, higher resolution cannot be achieved with a light microscope.
