Oceanography is the study of the ocean and the cryosphere are the portions of the earth that are just frozen water (ice). When fresh water glaciers melt, they lower the salt levels in the ocean and and oceanographer studies that and makes sure that it wont have too much of an effect. The cryosphere plays a significant role in the global climate.
C. Infrastructure !!! Hope this helps
Polaris is a Cepheid star which means it is endlessly growing while the sun is a yellow dwarf also there would be about 46 suns in the polaris
In creases the density of the crust i think...
Answer:
1. x = 7.25
2. x = 36
Explanation:
1. Base on intersecting secants theorem, therefore:
DE × DF = DG × DH
DE = 11
DF = 11 + 10 = 21
DG = 12
DH = 12 + x
Therefore,
11*21 = 12(12 + x)
231 = 144 + 12x
231 - 144 = 12x
87 = 12x
Divide both sides by 12
x = 7.25
2. Based on the secant-tangent rule, we have:
CD*CA = CB²
CD = 12
CA = 12 + x
CB = 24
Thus:
12(12 + x) = 24²
144 + 12x = 576
12x = 576 - 144
12x = 432
Divide both sides by 12
x = 432/12
x = 36
