Answer:
B. Laccoliths
Explanation:
The intrusive landforms, or rather the intrusive igneous rocks, have been formed from magma that managed to cut through layers of rocks that already existed. As the magma has been cutting through, it has started to cool off inside the crust, and as it did, it solidified and formed the intrusive igneous rocks, or intrusive landforms. One of the landforms that are formed by intrusion are the laccoliths. The laccoliths have the shape of lens, or even as a mushroom, with their base part being relatively flat. The amount of magma that has built up managed to cause uplift of the land in the shape of domes.
Availability Heuristic
A heuristic is a mental shortcut that we often use to make judgments and decisions. Availability heuristic is based on the principle that the first things come to our mind when evaluating certain topics, events, and methods, must be the based on the more common occurrences, or must be more important than other available alternatives which do not easily come to mind.
The problem with this type of mental shortcut, however, is that it can easily be influenced or biased towards vivid, dramatic events, or recent news and information, especially those sensationalized by the media.
For example, people might take more precaution against murder and car accidents compared to illnesses such as diabetes and stomach cancer, as the two former are more sensationalized or are often reported in the news than the latter two. However, statistics show that in America, these illness actually take twice as much lives than murder and car accidents (source: http://study.com/academy/lesson/availability-heuristic-examples-definition-quiz.html).
Answer:
concern over germs
Explanation:
Contamination is a type of OCD characterized by obsessive concern about germs.
I would say the following:
1) access to food and water. This means that they should be next to water sources (rivers) and fertile ground
2) construction material: wood and/or stones
I would say that a location on a trade route would also be beneficial (and rivers were trade routes: this explains why so many cities were on rivers!)
