<em>air moves because of two reasons..
1 temperature difference
2 pressure difference
<u>1 temperature difference :
</u> when there is temperature difference in the atmosphere ,,hot air rises and cold air takes its place ... so movement of air occurs..
<u>2 pressure difference:
</u><u /> also when there is pressure difference in atmosphere ,, air moves away from the area where there is more pressure..
<u>if there is no temperature and pressure difference then air will not move...

Lava flows are the least hazardous of all processes in volcanic eruptions. How far a lava flow travels depends on the flows temperature, silica content, extrusion rate, and slope of the land. A cold lava flow will not travel far and neither will one that has a high silica content. Such a flow would have a high viscosity<span> (a high resistance to flow). A basalt flow like those in Hawai'i have low silica contents and low viscosities so they can flow long distances. Such a flow can move as far away as 4 km from its source and have a thickness of 10 m (Bryant, 1991). These flows can move at rates of several kilometers per hour (Scott, 1989). </span><span>More silica-rich flows can move as far away as 1.3 km from their sources and have thicknesses of 100 m (Bryant, 1991). These flows can move at rates of a few to hundreds of meters per hour (Scott, 1989). If a lava flow is channelized or travels underground in a lava tube then the distance it travels is greatly extended.</span>
Answer:
Makes night and day and makes seasons
Explanation:
With a lack of resources, businesses are not able to keep up with production, causing a drop in products. with the drop in products will cause many businesses to lose money, and employees would have to be let go. aid farmers were to not be able to produce or sale their crops, they would not be able to make any profit, and the crops would not be used and would eventually rot. without the crops could bring a lack food in the cities. an example of a lack of resources is in the great depression with the dust bowl that caused the soil to be taken away from farms, and dust storms ravaged the plains.
Two artifacts found in the same stratigraphic layer are assumed to be of similar age due to the Law of Association.
The principal laws of the association are contiguity, repetition, attention, pleasure-pain, and similarity. The fundamental legal guidelines were formulated with the aid of Aristotle in about 300 B.C. and by way of John Locke in the 17th century.
Aristotle counted 4 laws of association when he examined the techniques of remembrance and recall: The law of contiguity things or events that occur near each other in space or time tend to get related collectively in the thoughts. Laws of the association are the principle underlying the connections inside the memory between certain ideas, feelings, or behaviors.
Aristotle's analysis of gaining knowledge of memory consists of four laws of association: the legal guidelines of continuity, assessment, frequency, and similarity. Accounting for learning and reminiscence in phrases of such legal guidelines of affiliation is referred to as institutions.
