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.
Answer:
25 m
Explanation:
Given:
v₀ = 10 m/s
v = 0 m/s
a = -2 m/s²
Find: Δx
v² = v₀² + 2aΔx
(0 m/s)² = (10 m/s)² + 2 (-2 m/s²) Δx
Δx = 25 m

Answer:
Explanation:
There are three types of waves mainly.
1. Mechanical waves : Which needs a medium for there propagation. For example, sound waves
2. Non mechanical waves : Which do not need a medium or their propagation.
for example, light waves
3. Electromagnetic waves : Which are produced due to the interaction of electric and magnetic field. for example, X rays, light waves
The wave motion are of two types.
1. Transverse wave motion
2. Longitudinal wave motion
i hate this question.
Conservation of momentum - is when the total momentum before and after collision is equal.
Here is the formula darling,
p = p
mv = mv
See the pic for example. HmpH
