Answer:
Options (A), (B), (C), and (D)
Explanation:
The volcanic activity refers to the eruption of magma at the surface of the ocean floor and continental land areas, forming volcanoes.
Some of the tectonic settings that are associated with volcanic activity are as follows-
- Mantle plumes- These are the large uprising bodies of magma that are generated due to the formation of convection current in the mantle. These are localized body and are located away from the tectonic boundaries. For example, Hawaii is formed as the plates moved over the mantle plumes.
- Continental rifts- This refers to the eruption of magma at the surface of the continents, due to the divergent motion of two continental plates. It results in the formation of a rift, rift valley and then later forms an ocean.
- Island arcs- These are formed due to the collision of two oceanic plates, where the volcanoes are formed on the lighter oceanic plate due to the rising up of magma.
- Continental arcs- These are formed due to the collision between an oceanic and a continental plate, where the volcanoes are formed due to the uprising of magma in the lighter continental plates.

Determine an equation of a perpendicular line but with the same y intercept
Open bracket
A linear equation is represented with:
Where
By comparison:
So, the slope of is m
Because the new line is perpendicular to , the relationship between their slopes is:
Where
slope of the first equation
slope of the second equation
Substitute m for 
in
Hence, the slope of the new equation is: 
From the question, we understand that they have the same y intercept.
So, the equation of the new equation is:
Answer:
Magmas are mainly liquid and contain dissolved fluids such as water, most are less dense than the adjacent solid rock and so move upward.
Explanation:
Magma -
It is a semi solid particle and the igneous rocks are formed from magma .
Magma is basically found inside the surface of the Earth and may come out from Volcanoes , due to any tectonic movements .
The composition of magma is basically molten form of rock along with gas bubbles and some crystals .
The magma is very dense in nature and slightly viscous and hence can flow , being semi - solid in nature .
Answer:
Hinduism did not spread outside of its homeland in India.
Explanation:
Hinduism is one of the oldest religions in existence and it is also one of the major religions by having a very large number of followers. This religion is considered a national religion as well, and this is due to the fact that almost all of its followers live in one nation. Basically, this religion emerged in the Indian subcontinent and remained there.
Hinduism is the only polytheistic of the major religions. It came to be because of the mixing of the cultures and religious beliefs of the native Dravidians and migrating Aryans. By merging both religions, Hinduism arose and spread out all over the historic territory of India. With the rise of Islam, Hinduism lost some of its followers, mostly in what is now Pakistan and Bangladesh, while its followers remained almost exclusively in modern day India. Unlike the other major religions that managed to spread out of their cradles in one way or another, Hinduism did not.
