Unlike food web that involve a network of complex interactions among various organisms in an ecosystem. Food chain involve only a single chain of energy transfer from one organism to another through consumption.
Answer: Protons and electrons are far apart with lots of empty space in between.
Explanation:
Atom is defined fundamental part of a matter. Atom is composed of three sub particles protons, electrons and neutrons.
In an atom, electrons are located in orbits around the nucleus. Nucleus of an atom is located at center of the atomic sphere where protons and neutrons are present. Hence, it will be correct to say that "protons and electrons are far apart with lots of empty space in between".
The magnetic readings taken across mid-ocean ridges provide evidence that "the sea-floor is spreading".
<u>Option: A</u>
<u>Explanation:</u>
As researchers analyzed trends in the ocean floor rocks, they noticed further encouragement for expanding the seafloor. Previously we read that Earth is behaving like a giant magnet, with a north pole and a south pole. Remarkably, throughout the Earth's past, Earth's magnetic poles flipped themselves several times.
The last turnaround occurred nearly 780,000 years ago. If the magnetic poles now unexpectedly flipped, one would find its compass needle pointing south. Researchers have found that the rock forming the ocean floor contain iron and thus resides in a form of magnetized stripes.
If the mountain was in the Front Ranges of the Rockies, I would look for a thrust fault underlying the mountain since thrusting is a low angle fault which juxtaposes older rocks on top of younger and thickens up the stratigraphic sequence. Also, mountains can form from normal faults whereby the hangingwall of the fault or the side of the fault which is towards the inclination of the fault drops down relative to the footwall (the side under the fault) so I would also look for a normal fault bounding a cliff face of the mountain.,
