Answer:

High salt content in soil limits the ability of seeds to germinate, as well as plant growth and crop yields. Controlled leaching, typically through irrigation, removes or reduces to the total salt content in the soil, allowing for healthier crops.

Answer:

Leaching occurs when crops drain the soil of its nutrients, making it less fertile. Leaching can be overcome, however, by crop rotation. For instance, legume helps to restore nitrogen in the soil, which is essential for plant growth. Another way to prevent leaching is to plant cover crops during the off-season. Cover crops act as natural fertilizers because they are left to die and mulch on the surface, then they are tilled into the soil before the next crops are planted. This cover crop then provides the nutrients needed for the desired crop to grow and survive.

6. Cultural convergence occurs more rapidly with
arsen [322]

Cultural convergence occurs more rapidly with improved transportation.

<h3>What is cultural convergence?</h3>

Cultural convergence is the phrase used to describe how civilizations tend to alter and adapt when they are frequently exposed to different cultures. Cultures will become more similar the more they interact with one another. Time and points of interaction are two major aspects that affect cultural convergence. Greater commonalities between cultures emerge from longer exposure times, of course. Increased contact rates, accessibility to communication and transportation, and membership in the same groups all speed up the rate of convergence. It will take longer for a civilization to absorb the traditions of another culture if they are just sometimes exposed to it through pop culture media than if they are exposed to their food, language, art, etc.

A decision matrix chart is a useful tool for
Wewaii [24]
Step 1

List all of your options as the row labels on the table, and list the factors that you need to consider as the column headings. For example, if you were buying a new laptop, factors to consider might be cost, dimensions, and hard disk size.

Step 2

Next, work your way down the columns of your table, scoring each option for each of the factors in your decision. Score each option from 0 (poor) to 5 (very good). Note that you do not have to have a different score for each option – if none of them are good for a particular factor in your decision, then all options should score 0.

Step 3

The next step is to work out the relative importance of the factors in your decision. Show these as numbers from, say, 0 to 5, where 0 means that the factor is absolutely unimportant in the final decision, and 5 means that it is very important. (It's perfectly acceptable to have factors with the same importance.)

Tip:

These values may be obvious. If they are not, then use a technique such as Paired Comparison Analysis  to estimate them.

Step 4

Now multiply each of your scores from step 2 by the values for relative importance of the factor that you calculated in step 3. This will give you weighted scores for each option/factor combination.

Step 5

Finally, add up these weighted scores for each of your options. The option that scores the highest wins!

St. Petersburg—Miami is a megalopolis. True or false?
Arturiano [62]
This is true.

The definition of megalopolis is that it is a large urban area, huge and densely populated. St. Petersburg is definitely one, however, Miami is relatively small compared to other megalopolises so it might not fall within that category.
