Answer:
The advantages of mixture a grasses and legumes is;
* extend the growing season of a pasture
* improve the quality of forage
* improve flexibility to survive environmental conditions
* reduce susceptibility to insects and disease attacks
* improve the palatability
* increase the organic matter content of the soil over time because of grass root system
* reduce weed encroachment
* reduce erosion
* produce higher yields
The probable pasture production for perennial ryegrass in the northern hemisphere leaves some time when the grass is dormant. There are times when other feed will be needed. Utilizing another grass or legume that flourishes during the less productive periods for perennial ryegrass extends the season for production and maintains the quality of feed.
Answer:
It takes much longer to heat and cool the oceans than the continents.
Explanation:
The Southern Hemisphere and Northern Hemisphere, despite being equal in size and receiving the same amount of sunlight, have big differences in climate. This is the case because the Northern Hemisphere has much more landmass, while the Southern Hemisphere has much more ocean water.
The land is changing temperature much faster because it can heat and cool off very quickly, thus the temperature variations are very large, not just from season to season, but also between day and night. The water, on the other hand, is heating up and cooling off much slower, so its temperature is never oscillating a lot. This results in much smaller temperature swings, so the climate tends to be much milder than the climate in the Northern Hemisphere.
There are limited amounts of resources in a general area. Some civilizations may not have the ability to produce resources that they need. That makes 2 routes:
1) cooperation: They can cooperate with another people group that lives in a different region and trade with them
2) conflict: They can attack/raid another people group in a different region for the resources
