Answer:
A fault is a fracture or zone of fractures between two blocks of rock. ... This movement may occur rapidly, in the form of an earthquake - or may occur slowly, ... such as regions where one plate is being subducted under another as in Japan. When the dip angle is shallow, a reverse fault is often described as a thrust fault.
Explanation:
Answer:
Elevation
Index contours
Contour interval
Explanation:
Contour lines on topographic connect points of equal elevation on the earth crust.
They are used to delineate the elevation of the landforms in an area.
Index contours are heavier lines on the topographic maps. They have numbers for specific elevation. The elevation of the index contour is used in extrapolating those of other places on the map.
The difference in elevation between contour lines is called contour interval. Most maps usually have consistent contour interval.
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:
True
Explanation:
Water distribution around the globe is enough to meet the demands of the world populace, but the spatial distribution of freshwater is not. There are many regions around the world where domestic and economic water demands cannot be met due to environmental and climatological limitations. These are the challenges that limit the abstraction of clean water for anthropogenic use.
