Answer:
The pacific floor (oceanic crust) is thinner and more denser
Explanation:
The continental crust have a thickness of about 35 to 40 km on an average, and are composed of rocks that has less denser granitic minerals such as feldspar, quartz.
On the other hand, the oceanic crust have a thickness of about 7 to 10 km on an average, and it is comprised of denser mafic rocks that contains high amount of olivine and pyroxene minerals.
Due to this, the oceanic crust subducts below the continental crust during the time of collision.
Thus, the pacific floor (oceanic crust) is thinner and more denser, in comparison to the South American continental crust.
Answer: The rock cycle involves the transition of rocks from igneous to sedimentary and metamorphic
The older rock would underlie the younger, recently formed rocks
Explanation:
It has been noted by geologists that most of the oldest rocks on earth are metamorphic, this is because they have been buried to such a depth that temperature and pressure changes them.
These metamorphic rocks could be have been igneous or sedimentary, depending on their mode of formation (solidification of magma or denudation)
Metamorphic rocks can melt partially and find its way to the surface as magma, forming igneous rocks when they cool and solidify.
These igneous rocks can get exposed throught weathering, get eroded away and get deposited on another rock (either igneous, sedimentary or metamorphic) while cementation and compaction makes sure it hardens and consolidates properly
The law of superposition implies that younger rocks overlie the older ones, because they have been formed sequentially
In my opinion, the correct answer among the choices listed above is option C. The Big Bang Theory states that between 15 and 20 billion years ago, the universe began expanding out of an enormous explosion. However, the exact number is approximately 13.8 billion years ago.
By definition, Newton's First Law, also called the Law of inertia, indicates that "Every body perseveres in its state of rest or of uniform rectilinear motion unless it is forced to change its state by forces impressed on it."
This means that for a body to come out of its state of rest or of uniform rectilinear motion, it is necessary for a force to act on it.
<h3>Definition of inertia</h3>
So, in other words, all bodies are opposed to changing their state of rest or motion and this opposition is called inertia.
<h3>Body in equilibrium</h3>
In this way, a body is in equilibrium when the resultant of the forces acting on it is zero. That is, it is not possible for a body to change its initial state (be it rest or motion) unless one or more forces intervene.
