Light colored igneous rock is called felsic, it is high in quartz, muscovite mica, and orthoclase feldspar content. Dark colored igneous rock is called mafic, and contains a lesser amount of silica along with olivine, pyroxene, amphibole, biotite mica, and plagioclase feldspa
<span>Light coloured igneous rocks (felsic) tend to have greater silica and aluminum content and a lower iron and magnesium content than dark (mafic) rocks.</span>
Answer:
Line OX = 7.09
Explanation:
The question is incomplete. Find attached the complete question.
SOLUTION
Given:
Line OL is perpendicular to DX
Line DX = 13
Line PO = the hypotenuse of the larger triangle
Line PO = 10
Line BO = hypotenuse of smaller triangle
Line BO = 12
To find length of line OX, we would apply rule of similar and congruent triangles.
∆DPO = ∆XBO
<POD = <BOX
Line DP is parallel to line XB
Since length of side DX = 13
Side DX = side DO + side OX
Let side DO = x
Side OX = 13-x
(Adj of ∆DPO)/(Adj of ∆XBO) = hyp of ∆DPO/hyp of ∆XBO
DO/OX = PO/BO
x/ (13-x) = 10/12
12x = 10(13-x)
12x = 130-10x
12x +10x = 130
22x = 130
x = 130/22 = 65/11
x is approximately = 5.91
Therefore line OX = 13 - 5.91
Line OX = 7.09
Answer:
on Hudson Bay and extending for 8 million square km (3 million square miles) over eastern, central, and northwestern Canada from the Great Lakes to the Canadian Arctic and into Greenland, with small extensions into northern Minnesota, Wisconsin, Michigan, and New York, U.S.
Indirect effects include pluvial lakes, changes in sea level, and isostatic depression.
