Which Type Of Rock Is Pegmatite?A. Extrusive IgneousB. SedimentaryC. MetamorphicD. Intrusive Igneous

Answers

Answer 1

Answer:

D. Intrusive igneous

Explanation:

Diorite, granite, pegmatite are examples of intrusive igneous rocks. Extrusive igneous rock: These rocks erupt onto the surface resulting in small crystals as the cooling takes place quickly. The cooling rate is for a few rocks is so quick that they form an amorphous glass. Basalt, tuff, pumice are examples of extrusive igneous rock.

Answer 2

Answer:

It is in fact D. (Intrusive igneous)

Explanation: Intrusive igneous rocks crystallize below Earth's surface, and the slow cooling that occurs there allows large crystals to form. Examples of intrusive igneous rocks are: diabase, diorite, gabbro, granite, pegmatite, and peridotite.

Answers

Number 2, Number 3, Number 4

The Earth and Moon have different geologic processes. The geologic processes that are responsible for the Earth's continuous deformation and Formation are plate tectonics and volcanic activity. The correct option is (C & D).

What do you mean by the Earth's formation?

Around the young sun, 4.6 billion years ago, a mixture of dust and gas gave rise to the Earth. It expanded as a result of numerous collisions with asteroids, dust particles, and other expanding planets, including one final massive impact that flung enough rock, gas, and dust into space to create the moon.

The core accretion model, which is the first and most widely recognized hypothesis, does a good job of explaining how terrestrial planets like Earth are formed, but it falls short when it comes to large planet formation.

Therefore, the Earth and Moon have different geologic processes. The geologic processes that are responsible for the Earth's continuous deformation and Formation are plate tectonics and volcanic activity.

While European governments may not always adopt the same social model, European welfare states have certain major traits.

Acceptance of political responsibility for employment levels and circumstances, social safeguards for all people, social inclusion, and democracy are examples of these.

Social democracy is a governing system with principles similar to socialism but operating inside a capitalist framework. The concept, called after democracy, in which people have a say in government acts, promotes a competitive economy with money while also assisting individuals with low-paying employment.

In the twenty-first century, it has been popular to refer to social democracy as the European social democracies, particularly the real governments in Northern and Western European countries, mainly in relation to their welfare state model and corporatism collective bargaining system.

Therefore, option C is correct.

How does the big bang theory came into existence?​

Answers

[tex] \huge \sf \red{Answer:-}[/tex]

The best-supported theory of our universe's origin centers on an event known as the big bang. This theory was born of the observation that other galaxies are moving away from our own at great speed in all directions, as if they had all been propelled by an ancient explosive force.

Answer:

Cosmic background radiation still exists from the Big Bang and can be seen with radio telescopes. The big bang theory is the explanation of the red shift observed by Hubble.  

Explanation:

It is the theory that the universe began expanding rapidly from a singularity about 14 billion your ago and the universe continues to expand to this day, we can tell the universe is expanding because the further an object is from us the faster it is moving away from us. The universe may have been infinitely large at the Big Bang and it is getting infinitely larger. In the 1920s Edwin Hubble made the observation that the universe had a prevailing red shift. This implied that the present observable universe had a beginning. The Big Bang theory is an attempt to explain the beginning of the universe implied by the evidence of an expanding universe.  Logically if the universe is expanding outwards then extrapolating backwards all the universe must have existed in one small space at the beginning. Einstein's theory suggests the existence of singularities where time and space does not exist. The entire universe is a small space would create a singularity because of the massive density of all the matter of the universe being in one place.  The theory is that this singularity with its mass exploded creating our present universe. The theory does not explain where or how the singularity came to exist, but does explain the beginning of the universe.  The previous theory of a steady state universe was abandoned because of the empirical evidence of an expanding universe that had a beginning. The present theories of an oscillating universe of big bangs and big crush is being seriously questioned by empirically evidence that rate of expansion of the universe is increasing. The evidence of an increasing rate of expansion indicates that the present observable universe will have an ending it will not recycle.

Peaks in immigration to the United States reflect changing circumstances at the global scale. Refer to the graph above to answer
the following:

C. Identify an economic motivation for migration.

G. Describe how chain migrations impact the cultural landscape.

Answers

Answer:

C. The great depression scared many people away from the United States to the difficulty in finding jobs or maintaining a healthy life. In 70's and 80's, production of goods and other things drove up the demand for labor, as seen in the graph. Most Asian workers who came to America did so in order to send back money to Asia in order to support their families. They thought that this would be more beneficial then staying in Asia due to the extremely low pay.

D. The mass influx in migration effects a nations culture. Why? An increase of global views and perspectives on something can change the way a mass thinks. For example, the cultural idea behind food, as to why Chinatown is a thing in various states.

Anne releases a stone from a height of 2 meters. She measures the kinetic energy of the stone at 9.8 joules at the exact point it hits the ground. What is the mass of the stone?

Answers

Eₖ = √1/2 mv²

Eₖ/v² = 1/2 m

2Eₖ/v² = m

mgh = 1/2 mv²

gh = 1/2 v²

2gh = v²

v = √2gh

= √2 × 10 N/kg × 2 m

= 6.324 ms⁻¹

m = 9.8/(6424)²

= 9.8/39.993

= 0.245 g

I am not sure if it's correct.

i transposed for m in the first equation then to find the velocity I combined the potential and kinetic energy equation. there was no mass because velocity doesn't depend on the mass

Then I used earth's gravitational field strength (g) 10 N/kg and the 2 m was the height provided in the question
