You could try writing flash cards with the word on one side and definition on the other or you could write the word and definition 3 times each on a piece of paper. remember not to try and cram the night before the quiz because you will lose sleep and you may not remember what you studied. (;
An economy based on trade
Answer:
Option (3)
Explanation:
The elasticity property of rock describes how a rock that is subjected to stress undergoes bending and again comes back to its original position. In nature, most of the rocks are non-elastic as they undergo deformation due to the stress acting on them. So the rocks are not always perfectly elastic.
According to Hooke's law, in case of a comparatively small deformations of an object, the displacement that occurs on the rocks or the deformation size that occurs is directly proportional to the amount of load that undergoes deformation.
Hence, the correct answer is option (3).
The map of the United States that is representing the soil erosion, shows us a trend that the soil erosion is the biggest in the areas where there is the most agricultural activity in the country, mostly the Midwest, the southern part, and the lowlands east of the Appalachians.
It is no wonder that the areas where there is the highest agricultural activity have the highest wind and water erosion. What is now agricultural land, in the past had a natural protection of wild plants, but now it doesn't.
The constant plowing of the soil results in making the soil much more loose several times in a year, sot he wind is able to pick up particles easily, and the water is able to easily move the top layers.
The heavy usage of pesticides, herbicides, fungicides, and artificial fertilizers are also making the soil very loos, so the erosion has big effect.
Depending on the irrigation method, it can have a big effect, especially if it is irrigation through ditches, as the water will be pushing from one side and moving toward the other side, moving the top soil with it.
