Answer:
D. Water is the most abundant atom in Earth’s atmosphere.
Explanation:
An atom can be defined as the smallest particle of an element (e.g., oxygen, hydrogen, etc). Water is a molecule (H2O) because its atoms are connected by molecular bonds (i.e., water is not an atom). Water is the most abundant molecule on the Earth's surface which covers more than 70 percent of the world's surface. A water molecule contains one oxygen (O) and two hydrogen (H2) atoms which are connected by covalent bonds. Water is also a compound known as a diatomic molecule, i.e., a molecule composed of two atoms of the same type.
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
Explanation: The reason why many scientist, and well informed people say "The History of planet earth is full of change", is because that planet earth has colliding continents, and such beings of evolution right now we think we are the only living BEINGS in the universe, so the reason why The history of planet earth is full of change is colliding continents one day New York will be with Europe, and new governments will start forming, and sooner than later humans will start to evolve onto what is "The New world"
