Answer:
Oceanic part of this layer has a relatively homogeneous composition, while the other part is less uniform in composition
Explanation:
Your question is base on the earth crust which is either oceanic crust or continental.
The earth Lithosperic layer is divided into two part namely the oceanic crust and the continental crust.
The oceanic crust is more uniform in composition than the continental crust because of the kind of earth events that is predominant here. For example sea floor spreading . The oceanic crust is composed dominantly of Mafic rocks. The Mafic rocks are extrusive igneous rocks. This rocks are formed when magma intrudes into the ocean surface, due to rapid cooling this rocks solidified quickly to form these rocks that are mainly basaltic. The oceanic rocks are dominantly basaltic. The basaltic dominance makes the oceanic crust relatively homogeneous in composition.
Events like sea floor spreading whereby the oceanic floor diverge forming two parts are one factors that causes mantle materials(molten magma) to reach the surface to form this basaltic rocks. The separating point, the mid oceanic ridges is where new crust are formed from the up-welling of magma. As you move away from the mid oceanic ridges the rocks become older.
The return stroke (the current that cause the visible flash) moves upward at a speed of about 320,000,000 ft per second or about 220,000,000 miles per hour (about 1/3 the speed of light).
R is proportional to the length of the wire:
R ∝ length
R is also proportional to the inverse square of the diameter:
R ∝ 1/diameter²
The resistance of a wire 2700ft long with a diameter of 0.26in is 9850Ω. Now let's change the shape of the wire, adding and subtracting material as we go along, such that the wire is now 2800ft and has a diameter of 0.1in.
Calculate the scale factor due to the changed length:
k₁ = 2800/2700 = 1.037
Scale factor due to changed diameter:
k₂ = 1/(0.1/0.26)² = 6.76
Multiply the original resistance by these factors to get the new resistance:
R = R₀k₁k₂
R₀ = 9850Ω, k₁ = 1.037, k₂ = 6.76
R = 9850(1.037)(6.76)
R = 69049.682Ω
Round to the nearest hundredth:
R = 69049.68Ω
