D. all of the above
(oil spills and whatnot for the fuel).
Answer:
We know that sin(x) = cos(90°-x). In that sense, we know that:
sin(25°) = cos(90°-25°) = cos(65°)
If you put both values in a calculator, we get that:
sin(25°) = 0.4226
cos(65°) = 0.4226
Therefore: Sin 25° = Cos 65°
Savanna fires keep tree cover low and control forests from encroaching on the grassland. When tree cover is high, as in a forest, fires cannot apply as easily, halting the savanna's advance into the forest
<h3>What causes fires in most savanna grassland?</h3>
These fires are usually lit by cattle growers as part of their traditional management of the Savannas where their animals graze.
<h3>How is fire wrong for a savanna grassland?</h3>
The researchers found that the commonness of fires determines whether forest or savanna will dominate an area more than other factors such as rainfall, seasons and soil texture, particularly in areas with moderate precipitation.
Regular fires prevent trees from setting and savannas from turning into forest.
