How the fossil evidence helped you put the landmasses together (what was your process)
Otrada [13]

Explanation:

The idea behind using fossils to correlate two land masses was first put into limelight by a British geologist, Williams Smith.

According to the principle of fossil and fauna succession "fossils and fauna succeed one another in a define order".

This implies organisms evolve in predictable manner.

Since we know that certain types of organisms live within a period in time on the earth surface, we expect that such organisms would be fossilized in the geologic record and preserved.

  • Identify the fossil record in one part of the land mass. Log the rock types with the corresponding fossils in them.
  • On the other side, repeat the same process.
  • Look for unconformity surfaces where some part of the stratigraphic records might have been lost.
  • If the fossil records on one side corresponds with that on the other other side, it suggests that the land masses must have once been joined together.
  • The logic is that when the organism were on the same land mass, they thrived and lived together.
  • They became fossilized together till the lands separated.

What is the simplest formula of a solid containing a, b, and c atoms in a cubic lattice in which the a atoms occupy the corners,
Ilya [14]

Answer:

c. abc₃  

Step-by-step explanation:

1. a atoms

There are eight corners, each containing an a atom.

No. of a atoms = 8 × ⅛

No. of a atoms = 1

=====

2. b atoms

There is one central b atom.

=====

3. c atoms

There are six faces, each containing a c atom.

No. of a atoms = 6 × ½

No. of c atoms = 3

=====

4. Formula

The simplest formula is abc₃.

If an atom has 7 protons, 8 neutrons, and 10 electrons, then it has a net charge of . On the other hand, if an atom has 3 proton
zloy xaker [14]

Answer:

Neutrons play no role in the net charge of an atom, so you can ignore them here.

Proton = 7

Electron = 10

Net Charge = 7 - 10

= -3

Again,

Proton = 3

Electron = 2

Net Charge = 3 - 2

= 1
