In frogs, different mating seasons are a barrier to reproduction.
The answer is 4 I’m pretty sure
This was a major breakthrough in geology because it meant that sedimentary strata in diverse parts of a country or area could be correlated as belonging to the same formation which means they were formed at the same time historically so helped to put them in the correct sequence. If these strata contained valuable minerals like coal then it could aid in the search for coal. This helped William 'Strata' Smith in England to create his first geological map in the world of a whole country.
3. It's because of the heat underneath the crust of the Earth. Because heat rises, the molten rock and such underneath the crust rises to the top and then the movement underneath causes things on top to move.
4. Plates are the different sections that the lithosphere has been cracked into. These plates once all fit together as a giant plate called Pangaea.
5. An earthquake is a sudden, sometimes violent shaking of the ground, as a result of the shifting of tectonic plates, or volcanic eruption.
6. On the magnitude scale, earthquakes range from 2.5 or less (usually never felt but strong enough to be detected by seismograph) to 8.0 or higher. Causes extreme damage; enough to destroy whole cities at once if close enough to the epicenter.
7. Depends on what kind you're looking for. I'd look it up for your specific topic.
8. To apply a forces to something, usually resulting in a stretch.
9. The action of compressing something, to flatten or squeeze by pressure
10. A strain on the layers of something because of pressure, resulting in the shifting of those layers.
11. In areas undergoing extension or stretching. It's when the crust is extended.
12. The hanging wall drops relative to the footwall.
13. This is what happens when the hanging wall <u>rises</u> relative to the footwall. (The opposite of a normal fault)
14.
Intelligence is most likely to be the criteria for random mating in humans.
Explanation:
If random mating is taking place on the conditions that no evolution is taking place the genetic pool will be maintained through generations.
Random mating will be based on intelligence in humans because this is the trait which gets exhibited only when showcased otherwise remains hidden while other characters like personality, appearance and athleticism are phenotypically expressed character.
Random mating is not under the influence of genotype. Intelligence is a trait which needs to be more in human as random mating takes genotype frequency in consideration.
